TSA ID backup: passports work

If your driver’s license is not REAL ID-compliant, a United States passport book or passport card still gets you through Transportation Security Administration screening for domestic flights. (tsa.gov) The Transportation Security Administration began REAL ID enforcement on May 7, 2025, and noncompliant state licenses are no longer accepted by themselves at airport checkpoints. The agency says travelers 18 and older must show a REAL ID-compliant license or another acceptable document, including a passport. (tsa.gov) The State Department says both the passport book and the wallet-sized passport card are REAL ID-compliant. It says either one can be used for domestic air travel if you do not have a compliant state license. (state.gov) That distinction matters because many travelers still treat REAL ID as a separate travel document requirement, when the rule is really about what kind of identification the Transportation Security Administration will accept at the checkpoint. A passport satisfies that identity check even if your state license does not. (tsa.gov) Since February 1, 2026, the Transportation Security Administration has offered a paid fallback called TSA ConfirmID for travelers who arrive without a REAL ID or another acceptable ID. The agency’s identification page says the fee is $45. (tsa.gov) The Transportation Security Administration’s ConfirmID page says the $45 payment must be made through Pay.gov before the identity-verification process continues. A Pay.gov form for the program says it is for travelers 18 and older who do not have a REAL ID, valid passport, or another acceptable ID. (tsa.gov) (pay.gov) ConfirmID is not a substitute document. The Transportation Security Administration says it will attempt to verify identity after payment, which means a traveler without acceptable ID can still face extra screening and may not be allowed through. (tsa.gov) A passport card has one limitation that trips people up: the State Department says it works for domestic flights, but not for international air travel. Travelers who want one document for both domestic flights and overseas flying still need the passport book. (state.gov) For airport lines, the practical split is simple: a noncompliant driver’s license can slow or stop you, while a valid passport book or passport card counts as accepted identification at the checkpoint. That makes the passport the cleaner backup than paying $45 for ConfirmID at the airport. (tsa.gov)
