With Certified Proof

Never miss an SSA deadline. Get a certified receipt proving your appeal or application arrived — before the 60-day window closes.

From $0.60 with credits · $1.29 pay-as-you-go · No account needed

SSA appeals must be filed within 60 days of a denial. A SHA-256 certified receipt proves the exact date your appeal arrived at SSA — not the date you sent it, the date it was delivered. Verifiable by anyone at faxseal.com/verify.

Frequently asked questions

Why does the submission date matter for Social Security?

SSA appeal deadlines are strict — typically 60 days from the date of a denial notice. Missing by even one day can mean starting the process over from scratch. A certified receipt with a tamper-evident timestamp proves you submitted before the deadline, protecting your appeal rights.

What is a SHA-256 certified receipt?

When your fax is delivered, FaxSeal generates a receipt containing the SHA-256 cryptographic hash of your exact document, the SSA fax number dialed, and the confirmed delivery timestamp. The hash permanently ties the receipt to that specific document — verifiable by anyone at faxseal.com/verify.

How do I find my SSA field office fax number?

Each Social Security field office and Disability Determination Service has its own fax number. Visit ssa.gov/locator to find your local office, then call to confirm the correct fax number for your document type before sending.

Can I sign SSA forms and fax them in one step?

Yes. Use the Sign & Fax tool — draw your signature, place it on the SSA form, and fax directly from the same screen. No printing, no scanning, no fax machine required.

What if the fax fails to deliver?

You are never charged for an undelivered fax. Your card authorization is released immediately. If a fax fails near a deadline, retry immediately or contact your SSA office directly to confirm an alternative submission method.

Can a disability attorney use this for clients?

Yes. FaxSeal credits never expire — buy a bundle and use them across all your clients. Each fax gets its own certified receipt, giving you individual proof of timely submission for every case.
