What Is the TSA?
The Transportation Security Administration (TSA) is a federal agency within the U.S. Department of Homeland Security (DHS). Created in November 2001 in response to the September 11 attacks, the TSA is responsible for security screening at airports, protecting the nation’s transportation systems, and enforcing federal regulations related to air travel safety.
For most travelers, the TSA is best known for the security checkpoint process at U.S. airports — the screening area where passengers present identification, walk through metal detectors or body scanners, and have their carry-on bags inspected before boarding a flight.
What ID Do You Need at TSA Checkpoints?
Since May 7, 2025, all passengers aged 18 and older must present a form of identification that meets federal standards at TSA airport checkpoints. Acceptable forms of ID include:
- REAL ID — A state-issued driver’s license or ID card marked with a gold or black star
- U.S. passport or passport card
- U.S. military ID (active duty or retired)
- Enhanced Driver’s License (EDL)
- DHS Trusted Traveler cards — Global Entry, NEXUS, or SENTRI
- Permanent Resident Card (Green Card)
A standard driver’s license without the REAL ID star is no longer accepted for boarding domestic flights as of May 7, 2025.
TSA PreCheck: Faster Airport Screening
TSA PreCheck is a trusted traveler program that allows pre-approved, low-risk passengers to use expedited security screening lanes at more than 200 U.S. airports. PreCheck members enjoy benefits like:
- Keeping shoes, belts, and light jackets on
- Leaving laptops and liquids in carry-on bags
- Using shorter, dedicated screening lines
To apply for TSA PreCheck, you need to submit an online application, pay a fee ($78 for 5 years), and attend an in-person appointment for fingerprinting and identity verification. A certified birth certificate or valid passport is required as proof of citizenship during the enrollment process.
Once approved, you receive a Known Traveler Number (KTN) that you add to your airline reservations to access PreCheck lanes.
TSA PreCheck vs. Global Entry vs. CLEAR
| Program | What It Covers | Cost | Validity |
|---|---|---|---|
| TSA PreCheck | Expedited security screening at U.S. airports | $78 | 5 years |
| Global Entry | TSA PreCheck + expedited U.S. customs for international arrivals | $120 | 5 years |
| CLEAR Plus | Biometric identity verification to skip the ID check line (still need to go through physical screening) | $189/year | Annual |
What Documents Do You Need for TSA PreCheck?
When you attend your in-person enrollment appointment, you must bring:
- Proof of citizenship: A certified birth certificate, valid U.S. passport, Certificate of Naturalization, or Permanent Resident Card
- Photo ID: A government-issued photo ID such as a driver’s license or state ID
If you need a certified copy of your birth certificate for your TSA PreCheck enrollment, order it through Vital Records Online for fast, secure processing.
Frequently Asked Questions
Can I fly without an ID?
If you arrive at the airport without acceptable ID, TSA may still be able to verify your identity using alternative procedures, but this process takes significantly longer and is not guaranteed. It is always best to carry a valid, federally accepted form of identification.
Does a birth certificate count as a valid TSA ID?
A birth certificate alone is not accepted as a standalone form of ID at TSA checkpoints for adults. However, it is required when applying for documents that are accepted — such as a REAL ID, passport, or TSA PreCheck membership.
Do children need ID to fly?
Children under 18 do not need to show ID at TSA checkpoints when traveling with an adult. However, the accompanying adult must present valid identification.
Is TSA PreCheck worth it?
For frequent travelers, TSA PreCheck can save significant time at the airport. At $78 for five years (about $1.30 per month), most regular flyers find the convenience well worth the cost. If you also travel internationally, Global Entry at $120 includes TSA PreCheck and adds expedited customs processing.
