USPS Form 3544, the Postal Service Receipt for Money or Services, is a hand-written receipt a postal clerk fills out and hands you when the retail terminal can’t generate a standard register receipt, or when you’re making certain account-based payments like a permit imprint deposit. You don’t fill it out yourself. But it’s your only proof of payment for the transaction, so what’s written on it matters.
When a Clerk Issues Form 3544
The most common trigger is a technology failure. If the retail terminal or network goes down while you’re paying for postage, renewing a PO Box, or buying any other service, the clerk pulls a book of Form 3544 from behind the counter and writes the receipt by hand. Post offices are required to keep these books on hand for exactly this scenario.1United States Postal Service.

Even with the computers working, Form 3544 is the standard receipt for several account-based transactions:
- Permit imprint deposits. When you add funds to a permit imprint mailing account at the retail window, the clerk records your name, permit account number, and amount on Form 3544. A copy routes to the employee or business mail entry unit that manages your account in PostalOne! so the deposit is credited properly.
- Business Reply Mail and Postage Due account deposits. Same process, with the BRM or postage due account number written on the form.
- Sale of surplus equipment, supplies, or scrap by a post office.
- Release-of-information fees, when USPS charges for releasing certain records.
Permit imprint deposits are the most frequent reason business mailers see this receipt, because the form ties directly into PostalOne! for the account balance update.2United States Postal Service. Postal Bulletin 22136 – Handling Customer Permit Accounts
What the Receipt Should Show
The clerk completes every field. Form 3544 captures three essentials: your name, the amount of the transaction, and the account or permit number the payment applies to.2United States Postal Service.

Once payment is complete, the clerk applies an official round-date stamp. That stamp prints the specific post office location and exact date, and it functions as the post office’s seal confirming the transaction happened.1United States Postal Service.

What to Check Before You Leave the Counter
Take a few seconds to look over the receipt while you’re still at the window. Confirm your name is spelled correctly, the dollar amount matches what you paid, and the permit or account number is right if the payment was for a mailing account. A wrong account number can send your deposit to someone else’s permit, and untangling that later takes time.
Also check that the round-date stamp is legible. If you ever need to dispute a transaction or prove a deposit was made, a smudged or missing date stamp weakens your documentation. The clerk should have already applied it, but it’s worth a glance.
How Long to Keep Your Copy
If you paid for a business expense such as a permit deposit, bulk mailing fees, or postage, Form 3544 is a valid receipt for tax purposes. The IRS doesn’t require a specific format; it requires only that your records clearly substantiate the expenses you claim.4Internal Revenue Service. Recordkeeping A Form 3544 showing the date, amount, and purpose of the transaction meets that standard.
The general rule is to keep supporting records for three years from the date you file the return claiming the expense.5Internal Revenue Service. How Long Should I Keep Records If you underreport income by more than 25 percent, the IRS has six years to assess additional tax, so keeping the receipt longer is reasonable if that could apply to you.6Internal Revenue Service.

Beyond taxes, hold onto the receipt if a dispute over your permit account balance is possible. The post office keeps its own copies under federal retention schedules, but having your original means you’re not depending on someone else’s filing system when a question comes up.
