A California ID card for someone under 21 is a state-issued photo ID from the DMV that costs $40, stays valid for six years, and prints vertically so anyone checking it can see the holder is under 21 without reading a birthdate. You apply the same way as any adult applicant, with one added step if you’re under 18: a parent or guardian has to sign off.
What To Bring to the DMV
California requires documentary proof of both age and identity before issuing any ID card.1California Legislative Information. California Vehicle Code VEH 13000 – Identification Cards Gather these before your appointment:
- An original or certified birth certificate, valid U.S. passport, or another item from the DMV’s identity document checklist. The name has to match what you put on the application.
- Your Social Security number. You’ll give it to the DMV clerk; the physical card isn’t required, but you need to know the number.2California Department of Motor Vehicles. Identification (ID) Cards
- Parental or guardian consent if you’re under 18. A parent completes a consent section on the application, and the DMV’s online form has a spot for it.3California Department of Motor Vehicles. Apply Online for a Driver License or ID Card
Proof of California residency is not required for a standard ID. That requirement only applies if you go with the REAL ID version.
How to Apply
Start online. The DMV’s application form takes your legal name, date of birth, and physical description, and completing it in advance shortens what you handle in person.3California Department of Motor Vehicles.

Then book an appointment at your local field office. Walk-ins work, but appointments cut the wait sharply. At the counter, a DMV employee will:
- Scan your thumbprint. State law requires one on file before any ID card is issued.1California Legislative Information. California Vehicle Code VEH 13000 – Identification Cards
- Take your photo, which goes straight onto the card.
- Collect the $40 nonrefundable fee.4California DMV. Licensing Fees
You leave with a temporary paper ID. The plastic card arrives in the mail within three to four weeks.2California Department of Motor Vehicles. Identification (ID) Cards
What the Card Looks Like
The card prints vertically instead of horizontally, which is the layout California reserves for anyone 21 or older. A red bar shows the date you turn 21. If you’re under 18, a second blue bar shows the date you turn 18. Both bars give a bartender, cashier, or bouncer a straight yes-or-no on age-restricted purchases without having to work out the math from a birthdate.
Otherwise the card carries the same features as any current California ID: your photo, physical description, and a unique ID number.
Should You Get a REAL ID Version?
Federal REAL ID enforcement began on May 7, 2025. A standard California ID without the REAL ID marking no longer works for boarding domestic flights or entering some federal buildings.5Transportation Security Administration. REAL ID A U.S. passport still covers those uses, but if you want your California ID to get you through airport security, choose the REAL ID version.
You’ll know a REAL ID by the gold bear with a star in the upper-right corner. Selecting it at the time of application adds one requirement: two different printed documents showing your California address, such as a utility bill, mortgage statement, or rental agreement. If you’re a minor whose name isn’t on any household bills, the DMV lets you use a birth certificate or similar document to link yourself to whoever’s name is on the residency paperwork.6California DMV.

One boundary worth knowing: TSA does not require any ID from travelers under 18 on domestic flights.7Transportation Security Administration. Acceptable Identification at the TSA Checkpoint The REAL ID option matters most for 18-to-20-year-olds who fly domestically without a passport.
Reduced-Fee and No-Fee Options
Not every applicant pays $40. California has two programs that cut the cost:
- A reduced-fee ID for low-income applicants enrolled in qualifying public assistance programs, including CalWORKs, CalFresh, and county general assistance. You need a voucher from your County Public Assistance Agency or a qualifying nonprofit, submitted on DMV Form DL 937.8California DMV. Reduced/No Fee ID Card Program Information for Organizations
- A 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 on Form DL 933.8California DMV. Reduced/No Fee ID Card Program Information for Organizations
Either form has to reach the DMV within 90 days of being issued by the verifying organization. Both programs cover ID cards only, not driver’s licenses.
What Happens When You Turn 21
The vertical card doesn’t expire on your 21st birthday. California ID cards are valid for six years from the application date, and yours stays a legal ID until that date passes.2California Department of Motor Vehicles. Identification (ID) Cards Legally, you don’t have to replace it.
In practice, most people do. The vertical layout tells every bartender and door person “under 21” at a glance, and many venues will refuse or heavily scrutinize a vertical card even from someone clearly past their birthday. To switch to a horizontal card, apply for a replacement through the DMV. The fee is again $40,4California DMV.
