How to Find Your Representative's Mailing Address

Writing a letter to a member of Congress or to a state legislator is one of the most powerful things you can do as a citizen. Staff members count and report letters from real constituents because letters take more effort than emails or phone calls. A handwritten or typed letter on paper carries weight in a way that a tweet never will. The challenge is that finding the correct mailing address is not always obvious. Federal House members, federal Senators, state senators, state representatives, and the governor all have different addresses, and many of them have both a Washington office and one or more local offices in their home district.

For federal officials, the two main websites are house.gov and senate.gov. Both are official government websites maintained by the United States Congress. House.gov has a search tool where you type in your zip code and it tells you which one of the 435 House members represents you, along with the address of their Washington office and their local offices. Senate.gov lets you pick your state from a drop-down menu and shows you both of your state's two senators, with full contact information for each office. There are no ads, no fees, and no sign-ups. The information is free and accurate.

For state officials, you go to your state legislature's website. Every state has one. The address pattern is usually "[your state]legislature.gov" or "leg.[state].gov" or something similar. A web search for "[your state] legislature find my legislator" will take you straight there. Most state legislature websites have a "Find Your Legislator" tool that uses your home address to point to your state senator and your state representative. The site lists their office address at the state capitol and their email or phone number.

A few tips will save you trouble. First, members of Congress prefer mail sent to their district office rather than the Washington office, because mail to Washington is screened for security and can take weeks to arrive. Second, write the office address as it is listed on the official website word for word, including suite numbers and zip-plus-four. Third, address the envelope properly. For a House member, write "The Honorable [Full Name]" on the first line and "United States House of Representatives" on the second line. For a Senator, use "United States Senate" on the second line. With these basics, your letter will arrive at the right desk and have the best chance of being read by a staff member who can help.
