Required since 7 May 2025. Here's what counts, what alternatives the TSA accepts, and what to do if you arrive at the airport without one.
You may still fly. Get to TSA at least 2–3 hours before departure. Tell the officer you don't have REAL ID — they'll route you to identity verification. You'll need to answer questions and provide other identifying info (utility bills, credit cards, mail with your address, etc.). TSA can refuse; this is at the officer's discretion. Read the steps below.
A REAL ID-compliant driver's license has a star marking in the upper portion of the card — usually gold or black, sometimes inside a circle or shaped like your state's outline. If your license has no star and isn't marked Enhanced, it's NOT REAL ID-compliant for flying.
The five Enhanced Driver's Licenses (Michigan, Minnesota, New York, Vermont, Washington) also count — they're federally equivalent to REAL ID for domestic flights.
Children under 18 are not required to show ID when travelling with an adult.
If you don't have a REAL ID driver's license, any one of these works for US domestic flights:
Mobile Driver's License (mDL): Apple/Google Wallet driver's licenses are accepted at select TSA PreCheck lanes in a handful of airports (BWI, DEN, PHX, SFO and growing) but only as a supplement. Always carry the physical card too.
If you fly more than 2-3 times a year, paying $85-$120 once for a Trusted Traveler program saves you hours per year at security. TSA PreCheck ($85 for 5 years) keeps your shoes/laptop/liquids in your bag at any TSA checkpoint. Global Entry ($120 for 5 years) adds expedited US Customs re-entry from abroad and INCLUDES PreCheck. Clear ($199/year) is a separate biometric ID-verification line that gets you to the X-ray faster (then you still need PreCheck or standard screening). See the PreCheck / Clear / Global Entry decision tool to pick the right one for how you fly.
Apply through your state DMV. Standard documents required:
Cost varies by state ($15–$80). Most states process in 4–6 weeks. If you have a passport, you don't need REAL ID at all for domestic flying — though a star-marked license is more convenient than carrying a passport for short trips.
