Required for IPAC Billing 

■ Agency Location Code (ALC) — Enter the 8-digit Agency Location 

Code (ALC) if the method of payment will be IPAC. An ALC is an identifier 

assigned by Treasury for reporting purposes. The first 2 digits of the 8-digit 

ALC identify the department or agency, the third and fourth digits identify 

the particular bureau within the department, and the remaining 4 digits 

identify the particular agency account section within that bureau. An ALC 

is required for all IPAC transactions. Without the ALC, an IPAC transaction 

cannot be processed. If unknown, the ALC can be acquired from the 

agency’s finance or budget office.

■ Treasury Account Symbol (TAS) — Enter the agency’s Treasury Account 

Symbol (TAS) if the method of payment will be IPAC. The TAS is an 

identification code assigned by Treasury, in collaboration with OMB and 

the owner agency, to an individual appropriation, receipt, or other fund 

account. If unknown, the TAS can be acquired from the agency’s finance or 

budget office.

■ Business Event Type Code (BETC) — Enter the 8-character Business 

Event Type Code (BETC) if the method of payment will be IPAC. A BETC 

is an 8-character code used in the Central Accounting Reporting System 

to indicate the type of activity being reported, such as payment, collection, 

etc. It must accompany the TAS and the dollar amounts in order to classify 

the transaction against the fund balance with Treasury. If unknown, the 

BETC can be acquired from the agency’s finance or budget office.
