TSA PreCheck enrollment centers and the TSA contact center accept fax for name corrections and documentation updates. Use the fax number from your enrollment paperwork or TSA's website. Include your Known Traveler Number on all correspondence.

Why get a certified receipt when faxing CBP or TSA?

Federal agency correspondence often has response windows and appeal deadlines. A SHA-256 certified receipt creates an immutable record proving the exact delivery date and time — important if an agency claims they never received your submission or that you missed a deadline.

Can I fax customs import documentation to CBP?

Yes. Customs brokers and importers routinely fax CF-28 responses, entry corrections, and protest documentation to CBP port directors and import specialists. FaxSeal provides certified transmission records suitable for audit trails.

Can I sign CBP or TSA forms before faxing?

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

What if the fax fails to deliver?

You are never charged for an undelivered fax. Retry immediately and follow up by phone if a deadline is involved. Keep the failed transmission record as evidence of good-faith timely filing.
