Which of the following elements must be included in a notary stamp?

A notary stamp must include specific elements to ensure it meets legal requirements and clearly identifies the notary. The inclusion of the words "Official Seal" alongside the notary's name is crucial because it signifies the legitimacy of the stamp and the authority of the notary. This combination helps to prevent fraudulent activities and ensures that the notary's identity is authenticated whenever the stamp is used.

In contrast, including personal information like a notary's date of birth or a list of services provided is not necessary for the identification of the notary's official capacity. Additionally, while a notary's signature is important for the notarization process, it is not a mandatory element of the notary's stamp itself. Thus, adhering to the specific requirements, as highlighted in the correct answer, is essential for the proper function of the notary stamp within legal documents.
