The primary function of the notary seal is to provide authentication for the notarization. A notary seal serves as a crucial tool in the notarial process, verifying the identity of the signer, the legitimacy of the document, and confirming that the notarization took place as required by law. The seal includes important information such as the notary's name, the state of commission, and the commission number, all of which contribute to its validity.

When a notary applies their seal to a document, it indicates that they have followed the necessary procedures, properly identifying the signer and witnessing their signature. This authentication is what lends legal weight to the document and can help prevent fraud by ensuring that the parties involved are who they claim to be.

Other options, while they may touch on aspects of a notary's role, do not capture the essential purpose of the seal. For instance, while making documents look official is an incidental benefit of using the seal, it lacks the fundamental legal significance that is associated with its use. Similarly, endorsing a contract legally and collecting fees pertain more to the broader duties of a notary rather than the specific function of the seal itself.
