Because the U.S. Mint is no longer making pennies, the United States Postal Service is rounding to the nearest nickel on change due customers for cash transactions when pennies are not available.
Change due to the customer ending in 1, 2, 6 or 7 cents will be rounded down. Amounts ending in 3, 4, 8 or 9 cents will be rounded up.
If the total cash visit amount is less than 5 cents, the purchase amount will be rounded up to 5 cents, unless paid with exact change.
The Postal Services still accepts pennies as payment.
Credit/debit card or check transactions will not be rounded.
