The short answer: both are correct, but "driver's license" is more common in American English

In the United States, you will see both "driver's license" and "driver license" used officially and informally. The version with the apostrophe — driver's license — appears more often in everyday writing and in most state government documents. However, some states use "driver license" without the apostrophe on their official documents and websites. Neither version is wrong; the difference comes down to style and regional habit rather than grammar rules.

The apostrophe version treats "driver's" as a possessive noun (the license that belongs to a driver), which follows standard English punctuation. The no-apostrophe version treats "driver" as a modifier or descriptor of the license itself, similar to how you might write "student ID" or "library card." Both constructions are grammatically defensible, which is why you see them both in official use.

Key Takeaways

  • "Driver's license" with an apostrophe is the more traditional and widely used form in American English and appears in most state documents.
  • "Driver license" without an apostrophe is also used officially by some states and is not incorrect, just less common.
  • The difference reflects two valid ways of treating the relationship between "driver" and "license" grammatically.
  • When filling out forms or official documents, use whichever version your state's DMV uses on their own materials.
  • Grammar guides like the Associated Press Stylebook and Merriam-Webster prefer the apostrophe version, but both are understood everywhere.

Why some states dropped the apostrophe

Starting in the 1980s and 1990s, some state governments began removing apostrophes from compound nouns on official documents as part of a broader shift toward simplified, modernized writing. This trend affected not just driver licenses but also documents like "teachers certificate" and "mechanics license." The reasoning was partly practical — fewer characters to print and store — and partly stylistic, reflecting how people actually spoke and wrote in casual contexts.

States that made this change include California, Texas, Florida, and several others. You can verify which version your state uses by visiting your state's Department of Motor Vehicles website or looking at a sample license image. The version on the actual card or in the official state documents is the one to use when you need to match official language.

This shift was not unique to motor vehicle documents. Many government agencies, businesses, and organizations have adopted the no-apostrophe style as part of modernizing their written materials. It reflects a practical decision to streamline documentation rather than a judgment that one version is superior to the other.

What grammar guides say

The Associated Press Stylebook, which sets the standard for news writing across most American newspapers, recommends "driver's license" with the apostrophe. Merriam-Webster's dictionary lists "driver's license" as the primary entry. The Chicago Manual of Style also favors the possessive form. However, these guides acknowledge that "driver license" is used and understood without confusion.

The reason grammar guides prefer the apostrophe is that it clarifies the relationship: the license belongs to or is issued to a driver. Without the apostrophe, the relationship is less explicit, though context makes the meaning clear. In formal writing — essays, official correspondence, or professional documents — using "driver's license" is the safer choice because it aligns with what most educated readers expect.

Which version to use on forms and documents

When you are filling out a form, process, or official document, match the version used by the organization asking for the information. If your state's DMV website uses "driver license," use that version. If a federal form or a bank uses "driver's license," use that version. Consistency with the source document matters more than which version is technically "correct."

If you are writing something for yourself — an email, a note, a personal document — either version is acceptable. The apostrophe version is more formal and more widely recognized as standard, so if you have no reason to choose otherwise, "driver's license" is the safer bet. This approach keeps your writing aligned with what most readers will recognize as conventional.

How this applies to related terms

The same split appears with other license and certificate terms. You will see "teacher's certificate" and "teachers certificate," "mechanic's license" and "mechanics license," and "professional's license" and "professionals license" used interchangeably. The pattern is consistent: the apostrophe version is more traditional and formal, while the no-apostrophe version is increasingly common in official and simplified contexts.

This trend reflects a broader shift in American English toward removing apostrophes from compound nouns, especially in government and business writing. It is not a sign of error or carelessness; it is a deliberate stylistic choice made by organizations to modernize their language and reduce punctuation complexity. Understanding this pattern helps you recognize that both versions will continue to exist side by side.

When consistency matters most

If you are writing a document that will be read by others — a resume, a cover letter, a professional email — pick one version and stick with it throughout. Switching between "driver's license" and "driver license" in the same document looks careless, even though both versions are correct. Choose whichever version matches the tone and formality of your document, then use it consistently.

For official government or legal documents, follow the version used by the issuing agency. For personal or informal writing, either version works. The key is that your choice should reflect the context and audience, not uncertainty about which version is "right."

Frequently Asked Questions

Will using the wrong version cause problems with my process or document?

No. Both versions are understood and accepted everywhere. Government agencies, banks, employers, and other organizations will not reject a document or process because you used one version instead of the other. The difference is stylistic, not substantive.

What if I see both versions used in the same document?

Inconsistency within a single document usually reflects that it was written or edited by multiple people, or that it was updated over time without full revision. If you are writing something, pick one version and use it consistently throughout. If you are reading something with mixed usage, it does not indicate an error in the document itself.

Is "driver license" becoming the standard?

It is becoming more common in official government documents, but "driver's license" remains the more widely used version in everyday American English and in formal writing. Neither is replacing the other; both are likely to remain in use indefinitely.

Which version should I teach my children to use?

Teaching "driver's license" with the apostrophe is the safer choice because it aligns with what most grammar guides recommend and what most formal writing uses. Once they understand that both versions exist and are correct, they can adapt to whatever style their school, employer, or organization prefers.
