Requirements for the Use of Your California State Notary Public Seal

Becoming a notary public gives you the versatility to provide an essential service to businesses and individuals alike. The ability to have a document notarized is something that almost everyone at one point in their life is going to need – notaries are never going to go out of style. However, some states, like California, have rigid standards that must be met for any notary public that wishes to put their seal of approval on a document. Here’s what you need to know about what your California notary public stamp and seal should look like.

In California, a notary public is required to use a rubber stamp as their official seal of office.

However, this doesn’t mean that you can’t use an embossing seal as well; while it can’t be used in lieu of a rubber stamp, it can be affixed in addition to it. However, you can’t use an embossing seal by itself, as California state law prohibits this.

Requirements for the Design and Layout of Your California State Notary Public Seal

There are some very strict requirements for California notary public stamps and seals in that the impression left behind by the seal must be clear enough to be reproducible via photograph. While notaries in California can choose between either a circular seal or a rectangular one, round seals cannot exceed two inches in diameter. Rectangular ones cannot exceed 2.5 inches in length and 1 inch in width; additionally, a rectangular seal must have either a milled or serrated edge border. All stamps must be made in black ink. Information that must be included within the seal itself is as follows:


  • The words “notary public”
  • The name of the notary as it appears on their commission
  • The county of origin regarding the notary’s bond and oath of office
  • The notary’s commission number
  • The expiration date of their commission
  • The seal manufacturer’s identification number
  • The State Seal of California

There are several other conditions and regulations that need to be met or abided by if you wish to be able to use your California notary public stamp or seal. For a more comprehensive list of this information, visit the appropriate section of the California Secretary of State’s website.

Much as it is in other states, notaries in California are responsible for providing their own stamps and seals. However, with the strict guidelines for California notary public stamps and seals, you need someone you can trust to provide you the right equipment.
