You can fly within the US without a REAL ID if you carry another ID on TSA’s list, such as a passport. What stopped working on May 7, 2025, is the standard state license without the REAL ID marking. Below are the 17 IDs TSA accepts, how to spot a compliant license, the rules for expired IDs and children, and the $45 ConfirmID fee for travelers with none of them.
Yes, with another acceptable ID. TSA requires adults 18 and older to show valid ID at the checkpoint, and a REAL ID-compliant license is only 1 of 17 entries on its list. Your situation decides what happens at security:
| Your situation | At the checkpoint | Cost |
|---|---|---|
| You have any ID on TSA’s list, or one that expired up to 2 years ago | Show it and go through screening | Nothing extra |
| You are under 18 on a flight within the US | No ID needed by TSA, though your airline may ask | Nothing |
| You are 18 or older with nothing on the list | Pay for TSA ConfirmID first, then verify your identity at the checkpoint | $45, valid 10 days, no guarantee |
TSA’s list covers citizens, residents, visitors and federal workers, and it can change without notice.
| Who usually holds it | IDs on TSA’s list | Note |
|---|---|---|
| US citizens | REAL ID-compliant state license or ID card; state Enhanced Driver’s License or Enhanced ID; mobile driver’s license; US passport; US passport card; DHS trusted traveler card (Global Entry, NEXUS, SENTRI, FAST) | A mobile license must come from an approved state and be based on a REAL ID, EDL or EID |
| Noncitizens living in the US | Permanent resident card; USCIS Employment Authorization Card (I-766) | A state REAL ID also works |
| Foreign visitors | Foreign government-issued passport; border crossing card; Canadian provincial driver’s license or Indian and Northern Affairs Canada card | No US license needed |
| Military, veterans, federal and transport workers | US Department of Defense ID; HSPD-12 PIV card; Veteran Health Identification Card; Transportation Worker Identification Credential (TWIC); US Merchant Mariner Credential | Defense IDs issued to dependents count |
| Tribal members | Photo ID from a federally recognized Tribal Nation | Includes Enhanced Tribal Cards |
TSA also accepts Apple Digital ID, Clear ID and Google ID pass as part of ongoing testing, but you must bring your physical ID too. A birth certificate and a Social Security card are not on the list. A suffix mismatch, such as Jr. on the boarding pass but not on the ID, is accepted.
Look at the top of the card: a compliant license carries a REAL ID marking in the upper portion, usually a star. No marking means TSA will not accept it. The exception is an Enhanced license or ID from Michigan, Minnesota, New York, Vermont or Washington, marked with a US flag and the word Enhanced, which TSA accepts although most carry no star.
Every state now issues compliant cards. According to TSA’s REAL ID FAQ, the DMV asks at minimum for proof of your full legal name, date of birth and lawful status, your Social Security number and 2 proofs of address. States can add requirements of their own.
TSA currently accepts the IDs on its list up to 2 years after they expire, so a US passport that ran out last year still works for a domestic flight. Stricter limits, such as 6 months of validity left on arrival, are set by the countries you fly to, not by TSA. Check the passport’s condition too: the State Department warns that airlines may deny boarding on a damaged passport, and it counts stains, significant tears and missing pages as damage.
Not for TSA on flights within the US: children under 18 do not need to show ID at the checkpoint, though a child flying alone needs one to get TSA PreCheck screening. Airlines set their own rules for travelers under 18, so check with yours.
International trips are different. Every child, infants included, needs a passport or trusted traveler document to enter the US, and when one parent stays home, some countries also ask for a consent letter signed by that parent.
TSA ConfirmID started on February 1, 2026, as the fallback for adults with nothing on TSA’s list.
The fee covers 10 days from the travel date on the receipt, so 1 payment can cover a short round trip. Each adult without ID pays separately, and anyone can pay for you if your name and dates are entered correctly. TSA’s ConfirmID FAQ confirms that travelers with a valid passport do not need it.
How to use TSA ConfirmID
A REAL ID is for domestic use only. On a trip abroad, the passport goes first on the list of documents you pack, because a REAL ID cannot be used to cross into Canada or Mexico, for other international travel or for international sea cruises. Enhanced licenses go further: DHS also designates them as border-crossing documents under the Western Hemisphere Travel Initiative.
Yes, if you pay $45 for TSA ConfirmID and TSA manages to verify your identity, which it does not guarantee. Without an acceptable ID or ConfirmID, an adult may not get through security. Children under 18 need no ID from TSA on flights within the US.
Not on their own if you are 18 or older, because neither is on TSA's list of acceptable IDs. An adult carrying only those needs ConfirmID, while children under 18 need no ID from TSA on flights within the US.
TSA will not accept it unless it carries another REAL ID marking at the top of the card or is an Enhanced license or ID, marked with a US flag and the word Enhanced. Without either, bring a passport or another listed ID, or pay $45 for ConfirmID before you fly.
Only if you also travel abroad. At TSA on flights within the US, a passport and a REAL ID work the same, but a REAL ID cannot be used for international travel.
No. A REAL ID cannot be used for international travel, and on a flight abroad your passport serves as your ID at the TSA checkpoint.
