This guidance represents the Food and Drug Administrations (FDAs) current thinking on this topic.  It 
does not create or confer any rights for or on any  person and does not operate to bind FDA or the public.  
You can use an alternative approach if the approach satisfies the requirements of the applicable statutes 
and regulations.  If you want to discuss an alternative approach, contact the FDA staff responsible for 
implementing this guidance.  If you cannot identify the appropriate FDA staff, call the appropriate

I.  INTRODUCTION  
 
 
This is one in a series of guidance documents intended to assist sponsors, applicants, and others 
making regulatory submissions to the Food and Drug Administration (FDA) in electronic format.   
 
This guidance explains how FDA will assign receipt dates to regulatory submissions to the 
Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and 
Research (CBER) for drug products.2  Although the guidance does not address receipt dates for 
citizen petitions, it applies to all of the following submission types: 
	   Investigational new drug applications (INDs) 
	   Premarket approval applications for drugs, including new drug applications (NDAs), 
abbreviated new drug applications (ANDAs), biologics license applications (BLAs), 
and amendments and supplements to these applications   
	   Master files (MFs) 
	   Postapproval studies (whether submitted as supplements to approved applications or 
otherwise) 
	   Submissions related to products marketed without an approved application  
                                                 
1 This  guidance has been  prepared by the Center for Drug Evaluation and Research  (CDER) and the Center for 
Biologics Evaluation and Research (CBER)  at the Food and Drug Administration. 
 
2 For purposes of this  guidance, unless otherwise specified, references to drugs and drug products include drugs 
approved under the FD&C  Act and biological products licensed under the PHS Act, other than biological products  
that also meet the definition of a device in section 201(h)  of the FD&C Act (21 U.S.C. 321(h)).  While CBER 
reviews some device submissions, this  guidance does not apply to submissions related to devices.

 Contains Nonbinding Recommendations 
	   Adverse event reports 
	   Original submissions, amendments, supplements, postmarket reports, and all other 
regulatory submissions to these applications.  
 
The guidance applies to these regulatory submissions if they contain information in either 
electronic or paper format, including hybrid submissions (i.e., mixed electronic and paper 
submissions sent in the same package to the appropriate receiving unit at FDA).  This guidance 
is not limited to those submissions made using the electronic common technical document 
(eCTD) format.  
 
Any provisions of FDAs regulations that describe how receipt dates or submission dates are 
determined for a particular type of submission take priority over this guidance.   
 
FDAs guidance documents, including this guidance, do not establish legally enforceable 
responsibilities. Instead, guidances describe the Agencys current thinking on a topic and should 
be viewed only as recommendations, unless specific regulatory or statutory requirements are 
cited. The use of the word should in Agency guidances means that something is suggested or 
recommended, but not required. 
 
 
II.  BACKGROUND 
 
When FDA receives a submission, the submission is assigned a receipt date.  This date may be 
used to determine important regulatory milestones.  For example, the receipt date of an IND 
establishes FDAs 30-day safety review cycle for the application.  Clinical investigations cannot 
begin during this 30-day time period, unless FDA notifies the sponsor that investigations may 
start earlier.3  Similarly, for a premarket approval application, such as an NDA, BLA, ANDA, or 
a supplement to an approved application, the receipt date determines the review performance 
goal date established under the applicable user fee legislation.4 It is important to recognize, 
however, that the receipt date as defined under this guidance may, as explained below, differ 
from the date of submission of an ANDA.  It is also important to distinguish, as explained 
further below, the receipt date as defined under this guidance from the decision by FDA 
whether or not an ANDA will be received within the meaning of the statute and FDA 
regulations. 
 
For certain postmarket submissions, the receipt date is used to help determine compliance with 
regulatory time frames.  For example, the receipt date for a postmarket study submission will 
determine whether the submission was received in accordance with the postmarket study 
requirements; the receipt date for a serious, unexpected postmarket adverse event report 
submission will determine whether the submission was received within the required 15 calendar 
day timeframe.

Biosimilar User Fee Act (BsUFA).

A.  Regulatory Distinction Between Submission and Receipt  
  
In some situations, the statute or regulations assign significance to the date on which an ANDA 
is submitted. For example, the date on which a substantially complete ANDA is submitted may 
determine whether or not that ANDA earns 180-day exclusivity vis-a-vis other ANDAs.  As 
stated in the guidance 180-Day Exclusivity When Multiple ANDAs Are Submitted on the Same 
Day, FDA applies a multiple first applicant approach to eligibility for 180-day exclusivity by 
considering all substantially complete ANDAs, amendments, and supplements containing a 
paragraph IV certification to a listed patent that are submitted on the same day as being first 
applicants when no paragraph IV certification to the patent has been submitted on any previous 
day, as long as the applications comply with the applicable requirements for submission. 5  
 
The Generic Drug User Fee Amendments of 2012 (GDUFA) include a provision regarding the 
date of submission for Type II drug master files and abbreviated new drug applications 
(ANDAs), including amendments and supplements to ANDAs.  Under this provision, these 
submissions are deemed to be submitted to FDA on the day when transmission to the electronic 
submission gateway (ESG) is completed, except when such a submission arrives on a weekend, 
federal holiday, or day when the FDA office that will review the submission is otherwise not 
open for business.  In that case, the submission is deemed to be submitted on the next day when 
that office is open for business.  GDUFA further states that if such a submission arrives in 
physical media form, it is deemed to be submitted on the day it arrives at FDAs appropriate 
designated document room.6  As explained further below, there may be a short lag time between 
the completion of the submission of an ANDA to the ESG and completion of the transmission 
from the ESG to the appropriate Center and production of the corresponding Official Center 
Acknowledgement.  In rare circumstances (when completion of the submission to the ESG fell at 
the very end of one day and the transmission of the corresponding Official Center 
Acknowledgment occurred at the beginning of the next day), that could mean that the date of 
submission would be different from the date of receipt. 
 
B.  Decisions to  Receive or File an Application for Review   
 
FDA regulations set forth criteria for the receipt and initial review of NDAs, BLAs, and ANDAs 
to determine whether they may be filed (in the case of NDAs and BLAs) or received (in the case 
of ANDAs) and placed into review.7  The decision whether or not the NDA may be filed or the 
ANDA may be received depends both on whether appropriate fees have been paid and whether 
the applications are found to be adequate for review. The receipt date for a premarket 
application, as described in this guidance, is the date on which an application is deemed to have 
arrived at FDA.  It should not be confused with our subsequent decision to file an NDA or a BLA 
for review or to receive an ANDA for review.

Act (making the date of  submission an issue  with respect to  forfeiture of 180-day exclusivity).

III.  POLICY 
 
A.  Receipt Date 
 
For the purpose of assigning receipt dates, if an electronic submission covered in this guidance 
arrives via the ESG Monday through Friday, it is deemed to have arrived at FDA on the date and 
time corresponding to the Official Center Acknowledgment (second acknowledgment) that is 
automatically sent to the submitter by the ESG.8  However, except as described under heading C 
below, if such a submission arrives through the ESG on a weekend, a federal holiday, or another 
day on which the FDA office that will review the submission is not open for business, it is 
deemed to have arrived at FDA on the next day when that office is open for business.  If a 
submission covered in this guidance is submitted in physical media (e.g., paper or CD-ROM), it 
is deemed to have arrived at FDA on the date on which it arrived physically at the appropriate 
receiving unit, while open for business, for the FDA center that will review the submission.    
 
The hours during which FDA can receive a submission  for the purpose of assigning a receipt 
date  are summarized in the following table. 9    
 
Delivery Method  Hours for Receipt of Submission 
Postal Service or Private  CDER  7:00 AM through 6:00 PM 
or Commercial Courier  CBER  8:00 AM through 4:30 PM 
   
ESG  Monday through Friday 12:00 AM to 11:59 PM,10 excluding 
federal holidays and days when the FDA office that will review 
the submission is closed  
 
B.  Submission Date 
When an application is submitted electronically, the submission and receipt occur at almost the 
same time.  In rare instances, however, an application submitted electronically may be submitted 
shortly before midnight and received shortly after midnight.  As referenced above, GDUFA 
states that certain types of submissions (i.e., Type II drug master files, ANDAs, and amendments 
and supplements to ANDAs) are deemed to be submitted to FDA on the day when transmission 
to the ESG is completed.  This occurs slightly sooner than the Official Center Acknowledgment 
                                                 
8 Additional information on  ESG acknowledgements can  be found  on FDAs website (Electronic Submissions 
Gateway  - Frequently Asked Questions).
9 The unusual situation  of a lapse of appropriations  requires a special explanation.  In some circumstances, as in  
October 2013,  some FDA functions may continue during a lapse in appropriations because funding is available from  
user fees that were collected in the previous fiscal year but not yet expended.  During a lapse in appropriations, 
however, FDA cannot accept  new applications for which required user  fees were not  paid prior to the lapse in  
appropriations.  This means that, for purposes  of receipt of such new applications, the government is considered not 
to be open  for business during a lapse in appropriations.  For that reason,  even if  document rooms are open during  
the lapse period, those rooms will not be considered to have received physical submissions of such new applications 
during that period.  Similarly, for ESG submissions,  new applications for which required user  fees were not paid  
prior to the lapse in appropriations will not be received until the lapse ends (i.e., the FDA office that will review the  
submissions will  not be considered  to be open  for business during  the lapse period). 
10 All times referred to in this guidance are Eastern Standard Time/Eastern Daylight  Time.

 Contains Nonbinding Recommendations 
(the ESGs second acknowledgment), which is used to determine the date of receipt.  For 
ANDAs and Type II drug master files, the date of submission is determined in accordance with 
GDUFA (i.e., the date on which transmission to the ESG was completed).     
For most submissions, the distinction between submission and receipt will have no significance.  
In rare instances, however, the date of submission thus determined may differ from the date of 
receipt, and certain significance may attach to the date of submission (see examples 1.k and 1.l in 
the Appendix to this guidance). 
C.  When Reporting Deadlines are Established in Terms of Calendar Days 
FDA regulations require that some information be reported to FDA within a certain number of 
calendar days. For example, 21 CFR 314.80 requires applicants to report each adverse drug 
experience that is both serious and unexpected as soon as possible and no later than 15 calendar 
days of initial receipt of the information by the applicant.  Whenever information must be 
reported to FDA by a deadline established as calendar days and the report is submitted 
electronically through the ESG, the information will be deemed to have arrived at FDA on the 
date and time corresponding to the Official Center Acknowledgment (second acknowledgment) 
that is automatically sent to the submitter by the ESG, whether that occurs on a weekday, 
weekend, federal holiday, or other day on which the FDA office reviewing the information is not 
open for business. 
D.  Deficiencies   
 
Occasionally, a submission that is provided in electronic format may have technical deficiencies 
that prevent FDA from processing, reviewing, and archiving the submission.  Examples of such 
deficiencies include, but are not limited to: 
 
	   Damaged media (e.g., unreadable CD-ROM) 
	   Failure to provide an electronically readable and valid FDA Form or submission (e.g., 
Form FDA 1571, Form FDA 356h), sent to FDA through the ESG 
	   Failure to provide a properly formatted and electronically readable CD 
	   Providing an electronic common technical document (eCTD) submission without the 
required index.xml and us-regional.xml files or using a sequence number that was 
submitted previously11  
	   Presence of a computer virus 
	   File format incompatibility 
	   Incorrect or inaccurate metadata, such as application type or number 
	   Providing an incomplete submission form that will not pass an internal technical 

validation for mandatory fields of metadata 

	   Incorrect or missing filename extensions that specify the file types 
                                                 
11    See the eCTD Validation Specifications  on the FDA website 
5 
 Contains Nonbinding Recommendations 
 
When such technical deficiencies occur, FDAs processing of the submission cannot begin until 
the technical deficiencies are corrected.  FDA considers a technically deficient electronic 
submission to be not received  (i.e., not present at FDA and not under review)  until all technical 
deficiencies are resolved and the submission is in a format that we can process, review, and 
archive.  Therefore, it is in the interest of applicants to prevent or identify and expeditiously 
correct technical deficiencies associated with an electronic submission, so that the submission 
can be processed and reviewed promptly and receipt dates and times can be set efficiently. 
 
The following describes the potential effects of technical deficiencies in a submission: 
	   The receipt date of an electronic submission is established tentatively when the 
submission arrives through the ESG and then established permanently when the 
submission is determined to be technically acceptable.  FDA posts technical information 
that describes the validation checks that FDA performs on each type of submission in 
electronic format (e.g., INDs, NDAs, BLAs).12      
	   FDA notifies the submitter of any technical deficiencies and asks that these be corrected 
as each difficulty is encountered.  It may not be possible to discover all technical 
difficulties at once.  For example, some  problems, such as an unreadable CD-ROM, 
prevent the discovery of further problems  within the content of a submission; those 
would be communicated at a later date. 
	   FDA determines the official receipt date to be the date a non-deficient submission, or 
resubmission, arrives at the appropriate designated receiving unit. 
If technical deficiencies in a premarket approval application are not resolved before the start of a 
new fiscal year (October 1), the user fee associated with the submission may be adjusted.   This 
would occur when there are changes to user fees at the beginning of the fiscal year.    
                                                 
12 Certain validation information, including the eCTD Validation Specifications, is posted on  the FDA website, 
under Electronic Submissions to CDER.

APPENDIX:  EXAMPLES OF DETERMINING RECEIPT DATE 
 
 
The following examples illustrate how FDA will determine the receipt date of submissions 
provided in electronic format.   
 
1.   All-electronic submissions, e.g., INDs, IDEs, BLAs, NDAs, ANDAs  
 
a.	   An IND arrives on October 1 via the ESG. The submission passes technical validation on 
October 2. The receipt date will be October 1, the date the submission was received.  
 
b.	   An IND in eCTD format arrives on March 3 via the ESG and is received by FDAs 
Center for Devices and Radiological Health (CDRH).  The submission has been directed 
to the incorrect receiving unit.  The submitter is notified of the error and is asked to 
resubmit the submission to the proper receiving unit.  The sponsor corrects its error, and 
the IND submission is received at CDER on March 4 and passes technical validation.  
The receipt date will be March 4, the date the submission was received at the proper 
receiving unit. 
 
c.	   An amendment to an IND  a special protocol assessment (SPA)  arrives on October 
1 on a CD-ROM and, after loading, it is determined that a critical document is corrupt.  
FDA notifies the sponsor, and the sponsor submits a replacement document on October 4; 
it is loaded and determined accessible.  The receipt date for the SPA will be October 4.  
 
d.	   A BLA in eCTD format arrives on October 1 via the ESG.  The index.xml file, a 
necessary component of the eCTD, is missing; therefore, the submission fails technical 
validation. FDA notifies the applicant that the submission failed the technical validation 
check and requests a corrected replacement eCTD.  The applicant submits a corrected  
replacement eCTD on October 4.  The corrected replacement eCTD passes technical 
validation on October 5. The receipt date will be the arrival date of the corrected 
replacement eCTD, October 4.  
 
e.	   An ANDA in eCTD format arrives on October 1 via the ESG.  The submission fails 
technical validation. FDA notifies the applicant that the submission failed the technical 
validation check and requests a corrected replacement eCTD.  The applicant submits a 
corrected replacement eCTD at noon on October 4.  The corrected replacement eCTD 
passes technical validation on October 5. The date of submission of the ANDA is the 
arrival date of the corrected replacement eCTD, October 4.  Whether the ANDA is 
received for review within the meaning of 21 CFR 314.101(b) is determined in 
accordance with that regulation. 
 
f. 	  An applicant submits an adverse event individual case safety report (ICSR) for an NDA 
product via the ESG on October 1.13  The submission passes through the ESG to the 
receiving unit, but cannot be loaded into the appropriate FDA safety database due to 
                                                 
13  FDA determines the receipt date for adverse event reports based on the  date the submission reaches the receiving 
units inbound folder. The ESG sends a first acknowledgment, and assuming that the report is successfully received 
by the inbound folder, a second acknowledgment is sent and used as the official center receipt date. 
7 
 Contains Nonbinding Recommendations 
errors in the incoming submission.  The reporter receives an acknowledgement from the 
system indicating the errors that prevented the submission from loading successfully.  
The reporter corrects the errors and submits the corrected submission via the ESG on 
October 3. The submission passes through the ESG to the receiving unit and successfully 
loads into the appropriate FDA safety database  on October 4.  The receipt date will be the 
arrival date of the corrected submission to the receiving unit, October 3. 
 
g. 	  A licensed manufacturer submits an adverse event ICSR for a BLA product via the ESG 
on October 1. The submission passes through the ESG to the receiving unit, but the 
target FDA safety database is unavailable due to a planned system outage for 
maintenance.  The database becomes available again on October 3, and the report is 
processed and loaded into the database at that time.  The receipt date will be the arrival 
date of the report to the receiving unit, October 1.  
 
h. 	  A manufacturer submits an adverse event ICSR for a prescription product without an 
approved application via the ESG on October 1.  Due to a technical problem FDA is 
having with the ESG, the report is not received by the ESG or the receiving unit, so the 
receipt date is not set.  The manufacturer is informed of the problem on October 3 and 
resubmits the report that day.  The report is now successfully received by FDA, via the 
ESG, which sets the receipt date as October 3.  Because the delay was the result of an 
FDA problem, FDA re-sets the receipt date to October 1. 
 
i. 	  An NDA in eCTD format arrives on September 29 on two CD-ROMs.  It fails technical 
validation due to a damaged CD-ROM.  The applicant is notified and resubmits new 
CD-ROMs.  The new CD-ROMs are received at FDA on October 4 and pass technical 
validation. Because the application is received on October 4, the next fiscal year, the user 
fee will be assessed at the new fee amount, and the applicant will be required to submit 
the appropriate user fee payment.   
 
j. 	  An applicant submits an NDA via the ESG at 8:30 pm Pacific Standard Time on June 1.  
This corresponds to 11:30 pm Eastern Standard Time (EST).  Arrival of the NDA 
through the ESG is not complete until 12:01 am EST on June 2.  If it passes technical 
validation, the NDA will be assigned a receipt date of June 2. 
 
k. 	  Three substantially complete ANDAs are sent to FDA electronically on April 20, all 
relying on the same reference listed drug and all containing paragraph IV certifications  
challenging a patent for the reference listed drug.  No applicant has previously challenged 
the patent. Of these three ANDAs, the last to arrive is transmitted to the ESG and that 
transmission is completed at 11:55 pm EST, but that ANDA does not completely arrive at 
CDER until 12:01 am EST the next day, April 21, according to the second  
acknowledgment automatically generated by the ESG.  Assuming they pass technical 
validation, the first two ANDAs will be assigned  a receipt date of April 20, and the third 
will be assigned a receipt date of April 21.  In accordance with GDUFA, however, all 
three ANDAs will be assigned a submission date of April 20 because the transmission of 
all three to the ESG was completed on April 20.  Consistent with the guidance 180-Day 
Exclusivity When Multiple ANDAs are Submitted on the Same Day, all three applicants 
8 
 Contains Nonbinding Recommendations 
are regarded as first applicants and may be eligible for shared 180-day generic drug 
exclusivity. Applicants in this situation are encouraged to make their submissions with 
time to spare, taking into account possible unexpected delays in transmission time to the 
ESG. 
 
l. 	 As in the last example, three substantially complete ANDAs are sent to FDA 
electronically on April 20, all relying on the same reference listed drug and all containing 
paragraph IV certifications challenging a patent for the reference listed drug.  No 
applicant has previously challenged the patent.  The third applicant begins transmission 
to the ESG at 11:55 pm EST on April 20.  Due to a slow connection, transmission to the 
ESG is not completed until 12:05 am April 21.  Assuming they pass technical validation, 
the first two ANDAs will be assigned a receipt date of April 20, and the third will be 
assigned a receipt date of April 21 (receipt dates corresponding to the ESGs second 
acknowledgment).  In accordance with GDUFA, the first two ANDAs will be assigned a 
submission date of April 20, and the third will be assigned a submission date of April 21, 
the date on which transmission to the ESG was  completed.  Consistent with the guidance 
180-Day Exclusivity When Multiple ANDAs are Submitted on the Same Day, the first two 
applicants are regarded as first applicants and may be eligible for shared 180-day generic 
drug exclusivity. The third is not. 
 
m.  An applicant submits an NDA via the ESG at noon on June 1.  T	 he applicable user fee for 
the application is not paid until June 10.  FDA will adjust the receipt date for the NDA to 
June 10. (This applies to physical as well as electronic submissions.)     
 
n. 	 An applicant submits an ANDA via the ESG at noon on June 1.  The applicable user fee 
for the application is not paid until June 30.  FDA will adjust the receipt date for the 
ANDA to June 30. (This applies to physical as well as electronic submissions.)  In 
addition, because the fee was paid more than 20 days after it was due, by statute FDA 
must consider the ANDA not to have been received until June 30.14   
 
 
2.         Hybrid (or mixed) submissions (electronic and paper) 
 
a. 	  A hybrid NDA containing 100 volumes in a paper format and datasets and labeling in an 
electronic format on a CD-ROM arrives on October 1.  The CD-ROM contains certain 
datasets in an incompatible file format; therefore, the submission fails technical 
validation. FDA notifies the applicant that the submission failed the technical validation 
check and requests a corrected replacement CD-ROM.  The applicant has difficulty 
reliably converting the files to an appropriate file format, which delays the arrival of the 
corrected replacement CD-ROM to November 15.  The corrected replacement CD-ROM 
passes technical validation. The receipt date for the complete mixed submission will be 
November 15.  
                                                 
14 FDCA Section  744B(g)(3).   Moreover, the ANDA will not be considered to be substantially complete when 
submitted,  and can only be  considered to be substantially complete as of the date the fee is paid, FDCA Section  
744B(n), a fact that can have important implications for claims of 180-day  exclusivity.  
9 
 Contains Nonbinding Recommendations 
b. 	  A BLA in electronic format arrives on October 1 via the ESG.  It passes technical 
validation on October 2. The receipt date would be October 1.  However, the application 
is actually incomplete and an amendment to the BLA in a paper format arrives on 
October 15. FDA chooses to review the amendment and has sufficient time to permit
