A facsimile signature is a reproduced copy of a handwritten signature, printed or stamped onto a document, not a digital or electronic signature.
- A facsimile signature is a reproduced copy of a handwritten signature, applied by stamp, print, or scan rather than written by hand each time.
- It is distinct from an electronic or digital signature, which is created and verified through software rather than reproducing a physical mark.
- Facsimile signatures have long been used on repetitive documents like checks, forms, and cover sheets, including ones sent by fax.
What Is a Facsimile Signature?
A facsimile signature is a reproduction of someone's handwritten signature, applied through a rubber stamp, a pre-printed image, or a scanned copy, rather than written by hand on each individual document. The word uses "facsimile" in its original sense, an exact copy, the same root behind the word facsimile itself.
Facsimile Signature vs. Electronic Signature
A facsimile signature is not the same thing as an electronic or digital signature. A facsimile signature reproduces a physical mark, while an electronic signature is created and verified through dedicated software with its own audit trail and identity checks. Businesses that need that software-based verification, rather than a reproduced physical mark, are looking at a different category of tool entirely.
Facsimile Signatures and Faxed Documents
Documents carrying a facsimile signature, like pre-signed forms or stamped approvals, have long been sent by fax exactly as printed, the signature travels with the rest of the page since it's part of the document's image rather than a separate data field. Sending that same document through secure fax keeps it encrypted in storage without changing anything about how the signature itself is reproduced or read.
A Common Case: A Pre-Signed Purchase Order
A supplier's accounting department stamps a facsimile signature onto routine purchase orders instead of signing each one by hand, since the same authorized signer approves every batch. Faxing that stamped order to a vendor sends the signature exactly as it appears on the page, no different from faxing any other printed document.
FAQ
Is a facsimile signature legally valid?
In many contexts, yes, a facsimile signature has been accepted on business documents for decades. Validity depends on the specific document, agreement, and jurisdiction involved, so checking with legal counsel is the safer path when enforceability really matters.
Is a facsimile signature the same as an electronic signature?
No. A facsimile signature reproduces a physical handwritten mark through a stamp, print, or scan. An electronic signature is created and verified through dedicated software with its own audit trail and identity checks, a different category of tool entirely.
