How to address your fax to Mike Crapo
By convention, correspondence to a U.S. senator is addressed to “The Honorable Mike Crapo”, with the salutation “Dear Senator Crapo”. Postal mail and courier deliveries reach the office at: The Honorable Mike Crapo, 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 one-issue fax is far easier to log under the right topic than a three-issue letter.
- Your name and mailing address. Senate offices prioritize constituents; an address in Idaho signals your position should be counted as a Idaho voter.
- Keep it to one page. A short, specific message — what you want the senator to do, and why it matters to you — is far more likely to get a full read than a rambling three-pager.
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.
