Fax the U.S. Senate

Congressional inboxes bury individual messages — a fax arrives as paper on the office machine, gets picked up by a staffer, and is logged as official correspondence. Find your senators below, click Send fax, and we'll prefill the fax number and a cover page addressed to them — you just attach your document. For the other chamber, see the House fax directory; for state issues, the governor fax directory.

Why fax your senator instead of emailing?

Same-day arrival

Physical mail to Capitol Hill sits in security screening for weeks. A fax lands on the office fax machine the same day you send it.

It stands out

Contact-form emails are high-volume and mostly earn form replies. A short fax in your own words reads as personal correspondence — and offices give personal messages more weight.

It's on the record

Offices log incoming faxes and tally positions on issues, and you get a timestamped delivery confirmation — handy if you follow up or escalate later.

Pick your senators below, attach your letter, and hit send. $0.50 per page, no account, delivery confirmation included. Jump to the directory ↓

How to fax a senator

  1. Find your senators. Each state has two — search the directory above by name or state, and fax both. A Senate office only counts you as a constituent of your own state's senators, so make sure your address is in the state.
  2. Open the prefilled form. Click Send fax — the office fax number and a cover page addressed to “The Honorable …” are filled in for you.
  3. Attach your letter. One page is plenty: one issue, a specific bill number if you have one, what you want your senator to do, and your name and mailing address.
  4. Send and keep the confirmation. $0.50 per page, no account — the timestamped delivery confirmation is your proof of when you sent it.

Do faxes to the Senate actually work?

Yes — with realistic expectations. Senate offices count every incoming message — letters, calls, emails, and faxes — and tally positions by topic, so your fax adds one to the count for your side. What a fax changes is visibility: it shows up as paper on the office machine the same day, in your own words, instead of one more email in a filtered inbox, and it leaves you a timestamped record of exactly when you made your position known. Personalized faxes — one page, one issue, your constituent address — carry the most weight, which is why advocacy groups still build entire campaigns around them.

Frequently asked questions

Do senators have fax numbers?

Most Senate offices publish a fax line — the Washington, D.C. office where available, otherwise a public state-office line. 64 senators in this directory had active fax numbers as of September 2026; senators often publish additional state-office fax numbers, and we list the one most recently confirmed as active.

Is a fax better than email or a phone call?

All three get logged, but they behave differently. Emails and contact-form messages arrive in high volume and usually earn a form reply. A call reaches a staffer live but leaves no written record of your words. A fax arrives the same day as a physical page that a staffer has to pick up, and it gives you a timestamped record — which is why advocacy campaigns still run on faxes.

Does faxing a senator actually work?

Yes. Offices count and tally every incoming message by topic, so your fax adds to the count for your side — and unlike a form email, it arrives the same day as paper a staffer physically handles, with a timestamped confirmation for you. Personalized, one-issue faxes carry the most weight.

How much does it cost to fax a senator?

$0.50 per page with PerPageFax, charged at checkout — no account or subscription. Most letters to Congress fit on a single page.

What should I put in my fax?

One issue, one page. Reference a specific bill number if you can, say what you want your senator to do, and include your full name and mailing address so the office counts you as a constituent. See our fax cover letter examples for ready-made templates.

My senator isn’t accepting faxes — now what?

Some Senate offices switch their fax lines off periodically. Try your state’s other senator, call the Capitol switchboard at (202) 224-3121 and ask for the office, use the contact form on your senator’s senate.gov site, or fax your representative in the House.

Fax numbers listed are each senator's published Senate office line — the Washington, D.C. office where available, otherwise a public state-office line — collected September 2026. Where the senator's own senate.gov site publishes the number, their page here links to it.
