California ID Under 21: What It Looks Like and How to Apply

To get a California ID under 21, you apply through the DMV with proof of identity, your Social Security number, and (if you’re under 18) a parent or guardian’s consent on the application. The card costs $40, is valid for six years, and is printed in a vertical layout so anyone checking it can see at a glance that the holder is under 21.

What the Card Looks Like

The under-21 card is printed vertically. Cards issued to people 21 and older are horizontal, so the orientation alone tells a bartender, clerk, or door person your age status without them having to read the birthdate.

The front of the card carries a red bar showing the date you turn 21. If you’re under 18, a second blue bar shows the date you turn 18. Those two bars give an instant yes-or-no answer on anything age-restricted. The card also shows your photo, physical description, and a unique ID number, along with the standard security features on current California IDs.¹

What To Bring

California law requires every ID application to be backed by documentary proof of age and identity.² For a standard card, plan on three things:

An identity document: an original or certified birth certificate, a valid U.S. passport, or another item from the DMV’s acceptable-document list. The name on this document should match the name you put on the application.
Your Social Security number. You give it at the counter; you don’t need the physical card, but you need to know the number.³
Parental consent if you’re under 18. A parent or guardian completes a consent section on the application, which is built into the DMV’s online form.⁴

For a standard (non-REAL ID) card, the DMV does not require separate proof of California residency. That changes if you choose the REAL ID version.

How To Apply

Start online. The DMV’s web application collects your legal name, date of birth, and physical descriptors like height, weight, and hair color before you ever walk into an office.⁴ Use the exact spelling of your name as it appears on your birth certificate or passport so nothing is kicked back for a mismatch.

Next, book an appointment at a DMV field office. Walk-ins work, but appointments cut the wait significantly. At the office, a DMV employee will scan a thumbprint (required by state law before any ID is issued),² take your photo, and collect the $40 nonrefundable fee.⁵

Before you leave, you get a paper temporary ID. The plastic card is mailed to you within three to four weeks.³

Should You Get the REAL ID Version?

Federal REAL ID enforcement began May 7, 2025. A standard California ID without the REAL ID marking is no longer accepted for boarding domestic flights or entering certain federal buildings.⁶ A U.S. passport still works for those purposes, but if you want your state card to clear airport security, you need the REAL ID version.

Choosing REAL ID at application adds one documentation step: two different printed documents showing your California address, such as a utility bill, mortgage statement, or rental agreement. For minors whose names don’t appear on household bills, the DMV lets you present a birth certificate or similar document to trace your relationship to the person named on the residency paperwork.⁷

One thing to know if you’re applying for a child: TSA does not require any identification for domestic travelers under 18.⁸ REAL ID really matters for the 18-to-20 crowd who fly domestically without a passport.

Reduced-Fee and No-Fee Options

Not everyone pays $40. California runs two programs that cut the cost:

Reduced-fee ID for low-income applicants enrolled in qualifying public assistance programs, including CalWORKs, CalFresh, and county general assistance. You’ll need a voucher from a County Public Assistance Agency or qualifying nonprofit, submitted on DMV Form DL 937.⁹
No-fee ID for people who meet the definition of unhoused under the federal McKinney-Vento Homeless Assistance Act. A government agency or qualifying nonprofit verifies eligibility and issues Form DL 933.⁹

Either form has to reach the DMV within 90 days of being issued. Both programs apply only to ID cards, not driver’s licenses.

What Happens When You Turn 21

The vertical card doesn’t expire the day you turn 21. Standard California ID cards are valid for six years from the application date and remain a legal form of identification through that period.³ You can keep using it.

Most people replace it anyway. The vertical layout tells every bartender and door person “under 21” at a glance, so even after your birthday you tend to get extra scrutiny or an outright no at bars and liquor stores. To swap it for a horizontal card, you apply for a replacement ID the same way you applied the first time, starting online and finishing at a field office. The replacement fee is $40.⁵
