Integrated USPS shipping No longer functioning for US addresses

As of 3/30/2025, USA based customers reporting an error message on checkout:

“No shipping methods are available for your order Please review your shipping address or contact us”

We are using the integrated shipping methods on the dashboard, specifically USPS.
Oddly, international shipping with USPS still works without issue, but domestic shipping within the US is not showing any options. Our USPS api and user ID is correct.

Anybody having similar problem? Solutions?

Update: After investigation, it appears to be an issue caused by a recent update to USPS API that has not yet been updated on Snipcart’s backend.

It seems that the old api will not be changed until next year –

" The Web Tools API platform will be retired on January 25, 2026. To avoid any service disruptions, migrate to the new USPS APIs. Contact API Support for help and provide any feedback via the [feedback form]

In the meantime, the USPS link is not working.

I am in contact sith the Snipcart support and dev team. The issue here seems to be that USPS Made changes to their API a few days ago, and those changes are incompatible with the existing code written by the Snipcart dev team. They are actively working on the issue.

Hey!

As @Eyegis-Garr said, there’s been a small change with the USPS web services. Thanks all for your patience as we worked to address the issue.

Cheers!
