What is another name for the official seal used by notaries?

The official seal used by notaries is commonly referred to as a notary stamp. This term accurately describes the tool used by notaries to impress an official mark on documents, which signifies that the notarization is authentic and that the notary has fulfilled their legal duties. The notary stamp typically includes essential information such as the notary's name, the state of commission, the commission number, and the expiration date of the commission.

This terminology is widely recognized and used in legal contexts, making it clear to all parties involved what the seal represents. Other terms like "notary annulus," "notary badge," or "notary imprint" are not standard terminology within the practice of notary services and do not convey the same universally understood concept of the official tool used for notarization. Therefore, the correct term highlighting the essential function of the seal in a notarial context is indeed notary stamp.
