John Cornyn Fax Number
Texas R — U.S. Senator
This office is not accepting faxes right now
John Cornyn'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 Cornyn, including other Senate offices that do.
How to address your fax to John Cornyn
By convention, correspondence to a U.S. senator is addressed to “The Honorable John Cornyn”, with the salutation “Dear Senator Cornyn”. Postal mail and courier deliveries reach the office at: The Honorable John Cornyn, 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 Texas signals your position should be counted as a Texas 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.
