# USPS The **USPS Addresses API** validates address information to help improve delivery accuracy and reduce failed shipments. **Setup** 1. Log in to the USPS developer portal at\ \ (You may need to create an account if you don’t already have one.) 2. Once logged in, select **My Apps** from the top-right toolbar. 3. Under **Getting Started**, follow the instructions to add a new app to your portal. 4. When prompted, add a name to your App - we suggest using "Formsort". 5. After the app is created, copy your **Consumer Key** and **Consumer Secret**. 6. Paste both values into the **USPS Addresses** integration settings in Formsort. Be sure to add a description, as this will help *you* identify your credentials in the Formsort UI. 7. Make sure to deploy/redeploy your flows after integration setup. Your USPS integration is now ready to validate addresses within your forms. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
