Frequently asked questions

Why does certified proof matter for insurance claims?

Insurance companies impose strict filing deadlines — often 30–180 days from the date of service for health claims, and 24–72 hours for auto accidents. A SHA-256 certified receipt creates an immutable record proving the exact delivery date, protecting you if the insurer later claims the submission was late or never received.

Where do I find my insurer's fax number?

For health insurance: check the back of your insurance card or log in to the member portal. For auto and home claims: the fax number is usually on your claim acknowledgment letter or the insurer's claims department page. For prior authorizations: providers find the fax number in the insurer's provider directory.

Can I fax a prior authorization request?

Yes. Prior auth fax submissions are standard in healthcare — your doctor's office does it daily. FaxSeal sends the fax to your insurer's prior authorization department and gives you a certified receipt proving the exact time it was received.

Can I sign forms before faxing?

Yes. Use the Sign & Fax tool — draw or type your signature, place it on the form, and fax in one step. No printing or scanning required.

What if my insurer says they didn't receive my claim?

Your SHA-256 receipt links directly to a verification page at faxseal.com/verify. Share the verify URL with your insurer — it proves the exact fax number dialed, the document hash, and the confirmed delivery timestamp.

What if the fax fails to deliver?

You are never charged for an undelivered fax. Your card authorization is released immediately. Retry immediately — insurance deadlines are strict and most claims departments answer their fax lines continuously.
