The USPS Funds Transaction Report is PS Form 8105-A, and the Postal Service requires it any time your money order purchases reach $3,000 or more in a single business day.1United States Postal Service. Money Orders – The Basics The clerk will ask for photo identification and personal details before completing the sale, and the record goes to the Treasury Department’s Financial Crimes Enforcement Network. The rule comes from federal anti-money laundering law, which treats USPS as a financial institution because it sells money orders and moves funds electronically.2Office of the Law Revision Counsel. 31 US Code 5312 – Definitions and Application
When the $3,000 Threshold Applies
Federal law bars any financial institution from selling a money order for $3,000 or more in currency without verifying the buyer’s identity and recording specific personal information.3Office of the Law Revision Counsel. 31 US Code 5325 – Identification Required to Purchase Certain Monetary Instruments A single domestic USPS money order tops out at $1,000, so reaching the threshold always means buying at least three.4United States Postal Service. Sending Money Orders
Regulations treat all money order purchases made during a single business day as one transaction for reporting purposes.5eCFR. 31 CFR 1010.415 – Purchases of Bank Checks and Drafts, Cashiers Checks, Money Orders, and Travelers Checks Going to a second window, walking to a different branch, or coming back after lunch does not restart the count. Only the face value of the money orders counts toward $3,000; the fees you pay on top do not. You can pay with cash or a debit card, but not a credit card.4United States Postal Service.

What Information PS Form 8105-A Collects
The form is designed to tie the transaction to a specific person. You’ll provide:
- Full legal name
- Residential address
- Social Security number, or alien identification number if you’re not a U.S. citizen
- Date of birth
- Occupation
- The type and serial number of each money order and the dollar amount of each one
The Privacy Act statement on the form describes occupation as voluntary, but refusing to give it may prevent the clerk from completing the sale.6United States Postal Service. PS Form 8105-A, Funds Transaction Report The regulation itself specifies the name, address, Social Security or alien ID number, date of birth, and the instrument details as required entries.5eCFR. 31 CFR 1010.415 – Purchases of Bank Checks and Drafts, Cashiers Checks, Money Orders, and Travelers Checks
If you’re buying money orders for someone else, whether a person, a business, or another organization, a separate section on the form captures that party’s name, tax identification number, and the nature of their business.
Fill it in with blue or black ink, and check that every field is legible before handing it to the clerk. Blank fields, an address that doesn’t match your ID, or an expired document will stop the transaction.
Acceptable Identification
You have to present a valid, unexpired photo ID. The clerk records the document’s identification number, the issuing jurisdiction, and the expiration date.6United States Postal Service. PS Form 8105-A, Funds Transaction Report Common documents include:
- Driver’s license
- State-issued ID card
- U.S. passport
- Military ID
- Foreign passport
- Matricula Consular card issued by Mexico
- NEXUS card issued by Canada
Digital or electronic versions of any of these are not accepted.7United States Postal Service. Acceptable Forms of Identification Bring the physical card.
Where the Report Goes
Once your ID is verified and the form is complete, the clerk enters the information into the Postal Service’s retail system, which transmits the record to the Financial Crimes Enforcement Network at the Treasury Department. FinCEN analysts look for patterns across the reports they collect from banks, check-cashing services, and the Postal Service.
Federal regulations require the records to be kept for five years and remain accessible during that period.8eCFR. 31 CFR 1010.430 – Nature of Records and Retention Period Filing a Funds Transaction Report is not an accusation and does not open an investigation. Most of these reports document ordinary transactions: rent payments, tuition, money sent to family.
Why You Cannot Split Purchases to Avoid the Form
Breaking a purchase into smaller pieces to stay under $3,000 is a federal crime called structuring. Buying $2,900 in money orders today and returning tomorrow for another $2,900, specifically to avoid the report, violates 31 U.S. Code 5324 even if the money itself is entirely legitimate. The statute punishes the act of evading the reporting requirement, not the source of the funds.9Office of the Law Revision Counsel. 31 US Code 5324 – Structuring Transactions to Evade Reporting Requirement
A structuring conviction carries up to five years in federal prison, a fine, or both. If the conduct is tied to other criminal activity or involves more than $100,000 in a 12-month period, the maximum doubles to 10 years and the fine goes up. Federal authorities can also pursue civil asset forfeiture against the funds. If you genuinely need $5,000 in money orders, buy them all at once, show your ID, fill out the form, and be done in a few extra minutes.
The Separate $10,000 Currency Rule
A different reporting rule applies to any currency transaction over $10,000 at a financial institution, which triggers a Currency Transaction Report to FinCEN.10eCFR. 31 CFR 1010.311 – Filing Obligations for Reports of Transactions in Currency For the Postal Service, that obligation does not cover payments made solely for postage or stamp-collecting products. For money order buyers, the $3,000 form is the one you’re almost always going to run into first.
