What is REAL ID? Do you need one to fly, what else TSA accepts, and the documents to apply (California example)

REAL ID is a driver license or state ID card that meets federal security standards. Since May 7, 2025, a regular (non-REAL ID) license is no longer accepted at TSA airport checkpoints for domestic flights. Newcomers usually ask three things: do I have to get one, can I still fly without one, and what do I bring to apply? Here are the answers from TSA and the California DMV.

1. What REAL ID is

The REAL ID Act, passed by Congress in 2005, set minimum security standards for state-issued licenses and ID cards. Compliant cards are REAL IDs and can be used to board domestic flights and enter military bases and most federal facilities that check ID. It is not a separate card but a version of your license or ID: in California you choose either the REAL ID version or the standard version marked “Federal Limits Apply”.

2. Do I need one?

California DMV says REAL ID is optional. You need it only if you want to use your license or ID to fly domestically or enter secure federal facilities. TSA’s acceptable ID list also includes US passports and passport cards, permanent resident cards, USCIS employment authorization cards (I-766), trusted traveler cards such as Global Entry, and foreign government-issued passports. So international students and work-visa holders can fly within the US with their passport.

Temporary paper licenses are not accepted. TSA currently accepts acceptable IDs up to two years after expiration. Travelers under 18 do not need ID for domestic flights, but the adult traveling with them does. DMV notes you do not need REAL ID to apply for Social Security benefits, enter a post office, visit a hospital or ride Amtrak.

No California license yet?Choose the REAL ID version when you apply for your first license. See the full checklist and the free practice test.

3. Forgot your ID? The $45 TSA ConfirmID

Since February 1, 2026, if you cannot show an acceptable ID, you can pay $45 to use TSA ConfirmID, and TSA will try to verify your identity:

• Pay only on Pay.gov, ideally before you travel, and keep the email receipt (printed or on your phone) to show at the checkpoint;
• One payment covers 10 days from the travel date entered; each traveler 18 or older without ID pays separately;
• The fee is non-refundable, verification is not guaranteed, and TSA says it may take about 30 minutes, so you could miss your flight.

It is a fallback. Frequent flyers should carry a REAL ID or passport.

4. Applying for REAL ID in California

For your first REAL ID, California DMV requires an office visit; it cannot be done through online or mail renewal. Bring:

• One identity document (original or certified copy) showing your full name and date of birth. Non-citizens can use, for example, an unexpired foreign passport with a valid US visa and approved I-94, a valid green card, or a valid EAD. If your current name differs, bring name-change documents such as a marriage certificate.
• Two different California residency documents with your name and the California mailing address that will be printed on the card, for example a utility or phone bill, bank statement, insurance document or vehicle registration. DMV’s document list says residency documents may be photocopies but must be printed on paper.
• Your SSN (DMV lists exceptions; you do not need to bring the card).

To save time, start the application online, upload your documents and save the confirmation code, then book an appointment. DMV notes knowledge tests are not started after 4:30 p.m. Fees are on the DMV licensing fee page.

5. Students and H-1B holders: can I get one, and when does it expire?

Yes. California DMV says anyone who can prove lawful presence can apply, including people on valid student or work visas. For temporary status, the card expires on the same date as your legal presence documents; after an extension you can apply for a new card with the extension documents.

6. Which option is easiest?

• Fly domestically often and do not want to carry a passport: get the REAL ID version of your license or ID.
• Just arrived and no license yet: fly on your passport, and pick the REAL ID version when you apply for a license so you only visit once (see the California driver license checklist).

Frequently asked questions

Do I need a REAL ID to fly in the US?

Not if you have another acceptable ID. Since May 7, 2025, a standard license is not accepted at TSA, but a valid passport (US or foreign), green card, employment authorization card or trusted traveler card is.

Can I fly domestically with my foreign passport?

Yes. Foreign government-issued passports are on the TSA list of acceptable identification.

What happens if I arrive at the airport without REAL ID or a passport?

Since February 1, 2026, you can pay $45 on Pay.gov for TSA ConfirmID. TSA will try to verify your identity, which may take about 30 minutes, but success is not guaranteed and the fee is not refunded.

What documents do I need for a California REAL ID?

One identity document (original or certified copy), two California residency documents with your name and address, and your Social Security number unless an exception applies. The first REAL ID requires an office visit.
