Arizona D — U.S. Senator
This office is not accepting faxes right now
Mark Kelly's office was listed as not accepting faxes as of August 2026. Senate offices turn fax lines off periodically — below are current ways to reach Senator Kelly, including other Senate offices that do.
How to address your fax to Mark Kelly
By convention, correspondence to a U.S. senator is addressed to “The Honorable Mark Kelly”, with the salutation “Dear Senator Kelly”. Postal mail and courier deliveries reach the office at: The Honorable Mark Kelly, United States Senate, Washington, DC 20510.
What to include
- One issue per fax. Reference a specific bill number or regulation if you have one — offices sort mail by topic, and a single clear ask gets tallied accurately.
- Your name and mailing address. Senate offices prioritize constituents; an address in Arizona signals your position should be counted as a Arizona voter.
- Keep it to one page. A short, specific message — what you want the senator to do, and why it matters to you — is read fully and logged.
Why fax still works for Senate offices
Security screening delays physical mail to Capitol Hill by weeks, and email forms bury individual messages. Fax arrives the same day with a timestamped transmission record, which is why offices — and the advocacy groups that track them — still publish fax numbers. Sending online, you get the delivery confirmation without a fax machine.
