Getting Started

The Do Not Pay (DNP) Portal matching logic is dependent on the search 

criteria or specific searchable fields available with each data source. DNP 

cannot give you specific guidance on what to do with a Portal match, but 

we can help you interpret the data shown and understand the reasons a 

match occurred using our different Portal functionalities (Online Search, 

Batch Matching, Continuous Monitoring).

Your Program’s Policies

Refer to your program’s policies on how DNP match data should be used 

from Online Search, Batch Matching, or Continuous Monitoring. DNP 

cannot be the only determinant of payment eligibility. You should check 

against another source to make a determination for payment eligibility 

and verification.

The Portal Matching Logic Explained

A. The Portal allows users to search for matches against relevant data 

sources using a variety of data elements:

B. The DNP Portal operates using an exact matching logic, meaning the 

text typed into the search boxes must match exactly to the record in 

the data source in order to produce a match. Therefore, it is crucial 

to type the data correctly in the search bar for the best results.

C. Not all data sources contain information in each of the searchable 

fields within the Portal. If you search within a field that is not 

included within a data source, no matches are returned against that 

data source.

For example, if you enter only a SSN/EIN/TIN, no matches are 

returned against LEIE-Public, OFAC, or SAM Exclusions-Public. Or if 

you enter only a Name, no matches are returned against CAIVRS. 

The primary search fields are SSN/EIN/TIN for restricted data 

sources and Name fields for public data sources except IRS tax 

exempt data sources that are public but searchable by TIN.

D. The Portal matching logic prioritizes the SSN/EIN/TIN field over the Name field. 

Data sources that can match on both the SSN/EIN/TIN field and the Name field 

will first look at the SSN/EIN/TIN field. If there is not a match with the entered 

SSN/EIN/TIN, the Name field is disregarded. Alternatively, if the SSN/EIN/TIN 

field is blank, then it will match against the Name field only.

Online Search Recommendations

Recommended Search Criteria for the Best Results Using Online Search

Since the Portal matching logic is dependent on the unique identifiers that are associated with each 

data source (i.e. SSN/EIN/TIN for restricted sources and Name for public sources), DNP recommends 

that you search as many data sources as you are legally approved for with all the search fields that you 

have access to for the best results.

This chart shows our recommended search criteria combinations to use to produce the highest 

number of matches on the two types of possible searches—an individual search or an entity search. In 

order to have the most accurate matches, use three search fields, if those data points are all available. 

If you suspect a resulting match is not actually the same entity you searched for (known as a “false 

positive”), we recommend attempting two separate searches—first using the SSN/EIN/TIN by itself and 

then using the Name by itself to avoid search logic prioritization issues.

Bulk Matching Functionalities:

DNP offers bulk file matching in two functionalities within the Portal:

Batch Matching

This function allows agencies to send a bulk payment file to DNP to be 

compared against their approved data sources. Matches at the time of 

the file submission are returned in the Portal.

Continuous Monitoring

DNP takes in an agency’s payee file and compares it against the 

approved data sources for that agency. These data sources are 

refreshed on a regular basis to continuously match the file when there 

is an update to either the agency file or the data source.

Match Result Strength

Within Batch Matching or Continuous Monitoring, matches are ranked 

according to their strength—Conclusive, Probable and Possible. See 

the chart below for the hierarchy and strength of the match results.

Matches will identify the data element that matched against a record 

in the relevant data source, and will help you determine the strength 

and relevance of the record match returned.

Important to note: If an entity is present on System for Award 

Management (SAM) Entity Registration Records (SAMENT), they 

are considered eligible to do business with the federal 

government. In the instance of bulk file matching, when an entity 

is not present on SAMENT, they are then flagged and the agency 

receives a “negative match result,” stating the “UEI/TIN is not in 

SAMENT.” Essentially, the DNP Portal produces a match result for 

not getting a match against SAMENT, meaning agencies then must 

verify payment eligibility of this entity who is not on SAMENT.

**Examples of Match Level and Match Type

Whitelisting

If a match that you know represents a proper 

payment repeatedly shows up in bulk file 

match results, you can choose to apply a 

Whitelist Reason, which will hide that match 

result for up to 90 days from that current 

date. You can whitelist matches for the 

reasons shown on the side.

Research Can Eliminate False Positive Matches 

Returned in the Portal

Screen for False Positives

Each match will contain different information such as matched criteria, birth date, death 

date, etc. This information may be used to help determine if the entity referenced is the 

entity for which you are searching. You must do further research on whether the Portal 

match is indeed the same entity the payment is referencing, or whether it is a false 

positive—a match to some data elements that may appear in your results that actually 

belong to a different entity from the one you are screening.

The matching logic in the DNP Portal does not differentiate between Social Security 

Numbers, Employer Identification Numbers, and Taxpayer Identification Numbers across 

available data sources. Keeping the matched data source in mind, determine whether 

any match within the SSN/EIN/TIN field is relevant to the search you were conducting. 

Pay special attention to the differences in match results when searching for an individual 

vs. a business, where the nine-digit SSN/EIN/TIN could indicate either entity or could 

produce matches for both entities.
