Stamp

Also called: notary stamp, seal, official stamp

The rubber or inked device a Pennsylvania notary uses to emboss or mark their name, commission ID, and expiration date onto a notarial certificate. Required by RULONA § 317 on every notarized document; format governed by 4 Pa. Code Chapter 167 as amended March 2026.

Under the 2026 final rule, every PA notary stamp must display the notary’s full commissioned name, the seven-digit commission ID, the words “Notary Public,” the county of appointment, and the commission expiration date. Stamps ordered before the 2026 rule should be replaced no later than commission renewal — sooner if the old stamp lacks the seven-digit ID.
