How do I mail a letter to my congressman?

Updated · By the SendMyLettersOnline team

Find your representative on house.gov and your senators on senate.gov, then mail your letter to their district or state office, or to their Washington office (ZIP 20515 for the House, 20510 for the Senate). Mail to Washington offices is screened for security, which delays it, so a local office or the member's web contact form is usually faster.

Writing a letter that gets read

  • Write to your own representative or senators; offices prioritize constituents.
  • Put your full home address on the letter so staff can confirm you live in the district or state.
  • Keep it to one issue, and name the bill number if there is one.

Asking for help with a federal agency (casework)

Congressional offices can contact agencies like USCIS, the IRS or Social Security for you. Because of privacy law, they usually need a signed privacy release form, found on the member's website. Include your case or receipt number and a short timeline.
