How to Fax Your U.S. Representative, Senator, or Governor
Find the published fax number for a U.S. representative, senator, or governor, then send the document online. Offices with no public fax stay listed with phone, address, and website.
A representative, senator, or governor fax goes to that office, and only when the office has published a number. There is no single Capitol fax line.
Start with the directory for the office you mean:
- Fax the U.S. House for a representative, delegate, or resident commissioner
- Fax the U.S. Senate for a senator
- Fax governors for a state or territory governor
Each page shows the phone, office address, and website. When a fax number is published, Send a fax fills it in. Domestic sends start at $0.99 for up to 10 pages, then about $0.08 per extra page. You see the quote before you pay. Pay on success: if delivery fails, the card hold is released.
This is a constituent fax, not a voted ballot. Where a state allows fax return of an absentee ballot, that packet goes to the election office in the instructions, not to a member or a governor. See Can You Fax an Absentee Ballot in 2026?.
Pick the right office
| Who you want to reach | Where to start | Then |
|---|---|---|
| U.S. representative, delegate, or resident commissioner | Fax the U.S. House | State, then the member |
| U.S. senator | Fax the U.S. Senate | State, then the senator |
| Governor | Fax governors | The state page |
House and Senate names, phones, and office addresses come from the public congress-legislators current file. A fax number is stored only when that office’s own website labels it as a fax. Governor pages are checked against each office’s published contact page. The directory shows the date those contacts were checked.
If you are not sure who represents you, use Find your representative on House.gov or Contact your senators on Senate.gov, then come back to the matching SingleFax page.
Send the fax
- Open the office page and confirm the name and state.
- If a fax number is listed, choose Send a fax. The number, name, and office are filled in on the send form.
- Put your name and a mailing address in the district or state on the document. Congressional offices usually expect that before they treat a message as coming from a constituent.
- Upload the pages and pay. Keep the transmission receipt.
A receipt records that the fax network reported delivery to the number on the page. It does not prove a staffer read the document, logged your position, or changed a vote.
Offices with no public fax still have a page: phone, address, and website, and no send button. Wait until that office publishes a number. Do not copy a fax from a third-party list or from an old news article.
What this page is not
- Not a ballot return. Faxing a voted ballot is a different rule, a different destination, and often not allowed. Follow the packet from your election office.
- Not an IRS or SSA filing. Those forms use their own numbers. See How to fax the IRS and How to fax Social Security.
- Not a promise the office will reply. Some offices answer by mail or not at all. The fax only delivers the pages to the published number.
