Yes. Tex. Gov Ann. 406.013 requires a Texas notary to use a seal of office to authenticate all his or her acts. A Texas notary must use a seal of office that clearly shows, when embossed, stamped, or printed on a document, the words "notary public, State of Texas" around a star of five points, the notary public's name, the date the commission expires, and the notary ID number. The notary seal may be a circular form not more than 2" in diameter or a rectangular form not more than one inch in width and 2 1/2 inches in length.
