Why do PO boxes keep going up?
USPS increases PO Box fees when private competitors raise prices in the same ZIP code.
As of 2026, 237 locations switched from “market-dominant” to “competitive” fee groups, letting USPS match nearby private rates. Fee hikes hit urban areas hardest, where private mailbox rentals (like UPS Store or FedEx Office) are common. You can check your ZIP code’s fee group on USPS.com under “PO Box Fees.” If your fee jumps unexpectedly, ask your local post office why.
What forms of payment does the post office accept?
USPS accepts Visa, MasterCard, American Express, Discover, Diners Club, JCB, and China Union Pay for online and in-person payments.

Add “Attn: [Name]” if the box is shared. Handwritten labels? Use a #2 pencil for barcodes. Unsure about formatting? USPS’s free “Create a Label” tool generates a compliant address block for you.

What happens if you put stamped mail in metered mail box?
Stamped mail and metered mail are both accepted, but metered mail bypasses the stamp line at the post office.

How long will mail take from zip code to zip code?
Standard mail averages 3 to 4 days, Priority Mail takes 1 to 3 days, and Priority Express Mail delivers in 1 to 2 days.
