As part of the overall effort to migrate our on-prem API environment to the cloud, beginning January 6th, 2025, the USPS API Developer Portal account registration process has moved to the Cloud USPS Developer Portal.
New Users
Please navigate to the Cloud USPS Developer Portal to get started. If you are using a 3rd-party software or plug-in and have been directed here by your provider, please note that they have given you a link for setup that is no longer valid, indicating that their integration is running on outdated technology. Before you can proceed, they will need to update their USPS integration. Please have your software provider contact us through API Support to request assistance with their cloud migration.
Current Users
Current users can still view their apps and credentials on the legacy Developer Portal and may continue to use their existing credentials to access the USPS APIs. To authorize an existing App to access protected account information (such as payment accounts, permits, CRIDs, MIDs, and subscriptions), please copy the App’s Consumer Key and enter it here. Should existing users wish to move to our Cloud environment, they can use their existing account to log into the Cloud USPS Developer Portal to create an app.
