Railroad Retirement Board: How to Find Your Fax Number

Does the Railroad Retirement Board accept fax?

Not for the purpose most people search for. The Railroad Retirement Board's own guidance is direct: "photocopied, faxed, or emailed documents are not acceptable as supporting documentation" for an annuity application. Its File-an-Application and Contact Us pages never name fax as a route for a beneficiary to submit an application or documents.

Where to fax, and where not to

• Form AA-12, Notice of Death and Request for Service Needed for Eligibility (the deceased worker's employer, not the beneficiary): fax (312) 751-7129. Source: RRB's own official Form AA-12.
• General field office correspondence (anyone, no stated purpose): each RRB field office lists its own fax on its own official Field Office Locator page (for example, Chicago 312-751-7136), but RRB doesn't say what should be faxed there.
• Annuity application or supporting documents (beneficiary or applicant): not by fax, RRB's own guidance excludes faxed documents. Use myRRB, Secure Message, mail, or an in-person field office visit instead.

Which route should I use?

1. If you're an employer verifying eligibility after a worker's death: fax Form AA-12 to (312) 751-7129.
2. If you're a beneficiary or applicant with supporting documents: don't fax them, RRB's own guidance says faxed documents aren't accepted, use myRRB, Secure Message, or mail instead.
3. If you need general correspondence with a specific field office: that office's own contact page lists its fax, though RRB doesn't specify what to send there.
