The Web Tools API platform stops working
Stopped working
Calls to these calls on USPS Web Tools stopped working on January 25, 2026.
What to use instead of these calls
Move to the USPS APIs on apis.usps.com (OAuth 2.0), mapping each Web Tools API to its equivalent: Addresses v3, Domestic and International Prices v3, Labels v3, Tracking v3r2, Locations v3.
The USPS APIs need a new account, OAuth credentials and, for labels, a payment authorization on the USPS Developer Portal.
The USPS Web Tools API platform was retired on January 25, 2026 and service disruptions are underway.
