USPS gives you a hard deadline on every PO Box renewal, not a soft reminder. Payment is due by the 10th of the month it is owed.
The box closes on the 11th if that payment does not arrive. There is no grace period built into that schedule anymore.
A COVID era extension used to soften the deadline, but USPS ended it in 2023. Knowing exactly how renewal works keeps your address, and everything addressed to it, intact.
Does USPS remind you before PO Box renewal is due
USPS often mails or emails a renewal notice ahead of the due date. Treat that notice as a courtesy, not a guarantee.
Notices can go to an old email address or get lost with other mail. The responsibility for on time PO Box renewal stays with you, notice or not.
How to renew your PO Box online
Sign in to your account at the official USPS PO Box page and open the Manage PO Box section. From there, select Renew PO Box.
Choose your term: 3, 6, or 12 months. The 3 month term requires automatic renewal with no opt out.
The 6 and 12 month terms let you turn that setting off. Pay with a credit or debit card, and you can save up to three cards on file for future renewals.
Review the confirmation before you submit. Keep the receipt in case a payment question comes up later.
Other ways to pay for PO Box renewal
A self service kiosk at many Post Offices accepts payment without a counter visit. Insert a card, select your box, and pay the same way you would online.
You can also mail a check to your local postmaster. Address it to the specific Post Office that issued your box.
In person payment at the counter remains available too. It is the most direct option if you already have questions for staff.
What happens if you miss the deadline
Your box closes automatically on the 11th of the month payment was due. USPS does not hold it open on a promise that payment is coming.
Renewing more than 10 days after the original due date can trigger a lock replacement fee. That fee exists on top of the rental cost itself.
A lapsed box sometimes gets reassigned or reset for security reasons. Avoid the entire situation by renewing a few days before the 10th rather than on the deadline itself.
Managing your box between renewals
Your online account is not just for paying. It also shows your current term, your renewal date, and your saved payment methods in one place.
Update your card on file before it expires. A declined payment at renewal time works exactly like a missed one.
Check your renewal date periodically rather than relying on memory. This matters most on the 3 month term, since it renews four times a year.
Closing a PO Box and requesting a refund
Sign in to your account and use the Close or Request Refund link if you no longer need the box. You can also tell a clerk in person at your Post Office.
USPS can prorate a refund for the unused portion of your term in many cases. The exact amount depends on how much time is left.
File a Change of Address form at the same time. That way, mail sent to your old box number forwards to wherever you are going next.
Forwarding typically lasts up to a year. After that, senders using your old address will need updated information from you directly.
Keeping the size or address you already have
Renewal keeps your existing size and box number. Nothing changes unless you specifically request it.
If your mail volume has grown, renewal is a natural moment to check whether a larger size fits better. See our guide to PO Box sizes if you feel like you are outgrowing your current box.

The bottom line
PO Box renewal comes down to one firm date each cycle. Pay by the 10th, or the box closes on the 11th.
Online renewal through your USPS account is the fastest way to stay ahead of it. Keep a current card on file, and check your renewal date occasionally rather than waiting for a reminder that may not come.
If your needs have changed, renewal is also a good moment to reconsider your size or close the box for a prorated refund. For everything else about how the box itself works, see our guide to what a PO Box is and how it works.
