What is Certified True Copy?

A copy of a document stamped and signed to certify it is a faithful, unaltered reproduction of the original.

A certified true copy is a duplicate of an original document — an ID, a certificate, a contract — that an authorised person stamps and signs to attest it faithfully matches the original. Banks, embassies, courts, and registries routinely require certified copies. PDF Verified lets an authorised user apply a "Certified True Copy" stamp with a date and serial, seal the file with a SHA-256 hash, and expose a public verification link so the certifying act is itself auditable.

Who can certify a copy

Typically a notary, lawyer, commissioner for oaths, or an authorised officer of the issuing organisation. The certifier applies a stamp and signature attesting the copy is true. Digitally, the certifier's identity, the timestamp, and a tamper-evident hash are captured automatically.

Tamper-evidence

Because PDF Verified hashes the sealed copy with SHA-256 and publishes the hash on a verification page, anyone can confirm the certified copy has not been altered since it was certified — something a paper certified copy cannot offer.
