While U.S. Post Offices aren’t open on Sundays, USPS self-service kiosks offer a convenient way to buy stamps and send mail outside of regular business hours.[1]

Several major retailers like Walmart and Kroger also sell stamps, allowing you to complete multiple errands in one stop.[2][3]

Below, I list where to buy stamps on Sundays (including available quantities).

What I Recommend

The best place to buy stamps on Sunday is your local U.S. Post Office. Although Post Offices close on Sundays, most lobbies are open and have self-service kiosks that sell stamps and postage for parcels.[4]

While you’re there, you can also drop off letters or parcels for USPS to process the next day.[4]

You can immediately apply the postage and drop your item in the dropbox instead of waiting for pickup or making an extra trip to the post office on a weekday.[4]

If your local Post Office doesn’t have a self-service kiosk, Walmart will likely be your best option; it’s local to most and is typically open from 6 a.m. to 11 p.m. on Sundays.[2]

The List

You can buy postage stamps at the register at the following places. Stamps are typically available for purchase during regular business hours, seven days a week.

I confirmed this information by contacting customer service representatives for each company and viewing online policy documentation.

The list below is in order beginning with the best options based on convenience and widespread availability.

Tip: U.S. postage stamps that are severely damaged are not valid, so be sure to keep them somewhere safe until you send your mail.[17]

Places That Don’t Sell Stamps

In the course of my research, I found that the following businesses don’t sell stamps on any day of the week.

I confirmed this by contacting several store locations for each retailer.


How can you find out if your nearest post office has a self-service kiosk?

You can use the USPS locator. Tap “Show Filters,” then mark “Self-Service Kiosk” and search for nearby locations.[6]

What are Forever stamps?

Forever stamps don’t have an amount printed on them and you can continue to use them to mail letters even after postage prices rise.[1]

What’s the maximum your letter can weigh with a single stamp?

If your letter weighs more than one ounce, you will need additional postage.[23]

In Summary

Although the United States Post Office closes on Sundays, you can still purchase stamps at one of its self-service kiosks in the lobby.[1]

You can also purchase stamps on Sundays at several major retailers, such as Kroger and Walmart.[10][2]
