Quick answer
To fly within the US, adults need a REAL ID-compliant licence (marked with a star) or another accepted ID such as a US passport. Without one, you must verify your identity with TSA ConfirmID and pay a $45 fee, which is valid for 10 days and does not guarantee you will be cleared.
What ID can you use instead of a REAL ID?
- A US passport or passport card
- A trusted traveller card (Global Entry, NEXUS, SENTRI)
- A US military ID
- A permanent resident card
How does TSA ConfirmID work?
- Verify your identity on TSA.gov and pay the $45 fee (you can pre-pay on Pay.gov).
- Show the confirmation email at the checkpoint.
- Allow extra time: verification can take 10–30 minutes or longer.
- The receipt is valid for 10 days.
Do children need a REAL ID?
TSA does not require children under 18 to show ID when travelling with an adult within the US. Your airline may have its own rules.
