What ID Do You Need for a Notary in California?

California is strict about acceptable identification for notarization. The rules come from Government Code §8202.1, and a notary who fails to verify identity correctly can face license suspension or criminal liability. Here's exactly what's acceptable, what's not, and what to do when you don't have ID.

The four required elements (Gov Code §8202.1)

Any ID used for California notarization must include all four of the following:

• Photograph of the bearer
• Physical description (height, weight, eye color)
• Signature of the bearer
• Serial or identifying number

The ID must be issued by a federal or state government authority. Tribal IDs and certain foreign government IDs qualify under specific conditions.

Acceptable IDs (the complete list)

Tier 1: Always acceptable (no extra steps)

• California driver license or state ID card issued by the California DMV
• Driver license or state ID card from another US state or territory (any state, plus DC, Puerto Rico, Guam, US Virgin Islands, Northern Mariana Islands, American Samoa)
• US passport book or passport card
• US military ID (CAC card, retiree ID, military dependent ID, Veterans Affairs ID)

Tier 2: Acceptable with conditions

• Foreign passport — only if stamped by U.S. Citizenship and Immigration Services (USCIS). The stamp must be visible and in the passport itself, not on a separate piece of paper.
• Inmate ID issued by California Department of Corrections and Rehabilitation (CDCR), with all four required elements, when the signer is in custody.
• Mexican Consular ID (matricula consular) — accepted by California notaries by long-standing practice, though not explicitly listed in §8202.1.

Tier 3: NOT acceptable

• Costco membership card
• AAA / auto club card
• Library card
• Employer badge or company ID (even with photo)
• Student ID from a private school
• Social Security card (no photo)
• Birth certificate (no photo)
• Bank card (debit/credit, even with photo)
• Concealed weapons permit (varies by state)
• Foreign driver license (without other qualifying ID)
• Foreign passport WITHOUT USCIS stamp

The five-year expiration rule

California is unusually permissive about expired IDs: Government Code §8202.1(c) allows an ID to be used if it was issued within the previous five years, even if it has since expired. This matters because:

• A driver license issued in 2022 that expired in 2025 is still acceptable until 2027 (5 years after 2022 issue).
• A passport issued in 2018 that expired in 2028 is still acceptable until 2023 — oh wait, the passport hasn't expired yet. Different math: a passport issued in 2018 that expired in 2023 is acceptable until 2023.
• An ID expired more than 5 years from its ISSUE date is not acceptable, regardless of expiration date.

This rule is especially helpful for elderly signers who don't drive anymore but still have a years-old expired license, or for international travelers with old passports.

Credible witness identification (when no ID is available)

If the signer has no acceptable ID at all, California allows credible witness identification under Government Code §8202.1(b). Two flavors:

Single credible witness

One person who:

• Personally knows the signer
• Personally knows the notary (or is known to the notary by sight)
• Has acceptable ID themselves
• Signs the notary's journal and takes an oath that the signer is who they claim to be

Two credible witnesses

Two people who:

• Personally know the signer
• Are not necessarily known to the notary
• Have acceptable ID themselves
• Have no financial interest in the document being signed
• Are not named in the document
• Both sign the journal and both swear under oath to the signer's identity

Credible witness identification is most commonly used for: very elderly patients in hospitals or care facilities whose IDs have long since expired or been lost, recent immigrants without USCIS stamps yet, or signers whose wallets were stolen.

What we do at the appointment

1. Visually inspect the ID for signs of tampering, expiration, and presence of all four required elements.
2. Compare the photo to the signer in front of us.
3. Compare the signature on the ID to the signature the signer makes on the document.
4. Record the ID details in the notary journal: type, serial number, issuing authority, and expiration date.
5. Photograph or thumbprint for certain documents (real estate documents involving a deed require a thumbprint per California Probate Code §8206(a)(2)(G)).
