Writing a physical letter is one of the most intentional, impactful ways to make your voice heard—but it only works if it lands on the right desk.
Whether you are dropping a postcard to a local city council member or reaching out to a federal representative, getting the address right is the first step. Below are trusted, non-partisan tools to help you locate your representatives at every level of government by simply entering your address or zip code.
1. Elected Officials
To see a complete list of your federal senators, congressional representatives, and state-level officials all in one place, use the Common Cause lookup tool.
2. United States Senators
If you want to look up specific committee assignments, contact forms, or Washington D.C. office addresses for your state's two U.S. Senators, you can search the official Senate directory.
3. U.S. House of Representatives
To find the direct mailing address for the specific representative serving your congressional district, use the official House directory.
A Quick Tip for Mail Delivery
Congressional staff members handle thousands of pieces of mail a week and often discard envelopes immediately after opening them to save space. To ensure your message receives a response, always write your full name, address, and zip code clearly on the back of your postcard.
