4.2 Acceptable Identification Documents

Key Takeaways

  • Passport, driver's license, and government nondriver ID cards are the primary qualifying documents
  • Any qualifying ID may be current or expired no more than 3 years before the act
  • Other government IDs qualify only if they bear the individual's signature OR photograph
  • The document must still be satisfactory to the notary, who may demand more
  • Social Security cards, credit cards, and birth certificates never qualify alone

The Three Primary Documents

MCA 1-5-603 names three documents that automatically qualify as documentary proof of identity when they meet the currency rule:

DocumentIssuerCurrency Rule
PassportU.S. or foreign governmentCurrent or expired ≤ 3 years
Driver's licenseAny U.S. state or jurisdictionCurrent or expired ≤ 3 years
Government nondriver ID cardState or federal governmentCurrent or expired ≤ 3 years

Note that a passport and a state ID card do NOT need to display a signature -- the statute treats these named documents as qualifying on their own. The signature-or-photo requirement (below) attaches to the catch-all "other government ID" category.

The 3-Year Expiration Window

This is the single most-tested number in the chapter. Montana, unlike many states that demand a current ID, accepts an expired document so long as it has not been expired for more than three years before the notarial act.

ID StatusAcceptable?
Current (not expired)YES
Expired 1 day to 3 yearsYES
Expired more than 3 yearsNO

Worked example: Today is 2026-06-14. A license that expired on 2024-02-01 (about 2.4 years ago) is acceptable. A license that expired on 2022-01-01 (over 3 years ago) is NOT acceptable, no matter how clearly the photo matches.

Other Government-Issued IDs

Beyond the three named documents, MCA 1-5-603 accepts any other government-issued identification only if it satisfies ALL of these:

RequirementDetail
Government issuerIssued by a government entity, not a private company
CurrencyCurrent or expired no more than 3 years
Signature OR photographMust contain at least one of the two
SatisfactoryMust satisfy the individual notary

Common qualifying examples: U.S. military ID, tribal ID, permanent resident ("green") card, foreign national ID card, and government-issued student IDs.

What Never Qualifies on Its Own

DocumentWhy It Fails
Social Security cardNo photo AND no signature requirement met as government photo ID
Credit or debit cardNot government-issued
Birth certificateNo photograph of the adult signer
Library or club cardNot government-issued
Any ID expired > 3 yearsOutside the statutory window

ID Inspection Checklist

When a document is presented, run this quick scan before relying on it:

  1. Photo matches the living person in front of you.
  2. Name matches the name on the document to be notarized.
  3. Expiration date falls within current-or-3-years.
  4. Signature (where present) appears consistent.
  5. Security features (holograms, microprint, UV elements) look authentic.
  6. No tampering -- no peeling lamination, mismatched fonts, or altered data.

Handling Name Discrepancies

A frequent real-world snag is a mismatch between the name on the ID and the name on the document. A signer named on a deed as "Elizabeth A. Carter" who presents a license reading "Beth Carter" or "Elizabeth Anne Carter-Smith" forces a judgment call. The notary must be reasonably certain the person on the ID is the same person named in the document. A nickname or a missing middle initial is usually reconcilable; a different surname (after marriage or divorce) often is not, without supporting documentation or a credible witness.

The safe practice is to notarize using the name as it appears on the ID, or to decline until the discrepancy is resolved. The exam rewards the cautious choice -- never "just write whatever the document says."

Foreign and Tribal Documents

Montana's acceptance of "any state" driver's licenses and U.S. or foreign passports matters for a state with significant cross-border traffic and seven federally recognized tribal nations. A foreign passport that is current or expired no more than three years qualifies as a named document. A tribal ID falls under the "other government-issued ID" category and must therefore bear the individual's signature or photograph and satisfy the notary. The same is true of a permanent resident card.

When a document is in a language the notary cannot read, the safest approach is to rely on the photo, the romanized name fields, and the machine-readable zone, and to demand a second qualifying ID if anything is unclear.

Worked Scenario: Multiple Documents

A signer offers a Social Security card and a credit card, insisting that "together they prove who I am." Neither qualifies: the Social Security card is not a government photo ID under the statute, and the credit card is not government-issued at all. Stacking two non-qualifying documents does not create one qualifying document. The notary must request a passport, driver's license, government nondriver ID, or another qualifying government ID -- or fall back to a credible witness. This is a favorite exam trap precisely because it feels reasonable in everyday life.

On the Exam

  • 3-year rule: the headline number -- expired up to 3 years is fine.
  • Named documents (passport, license, nondriver ID) qualify without a separate signature test.
  • Other government IDs need signature OR photo, never "both" as a requirement.
  • Notary discretion survives a technically valid ID -- more proof can still be demanded.
