A passport card is not accepted as Real ID for domestic flights or federal building access

The passport card — the wallet-sized version of a U.S. passport — does not meet Real ID requirements. The Department of Homeland Security accepts only the full-size passport book as a Real ID-compliant travel document. This matters because starting May 7, 2025, you will need Real ID-compliant identification to board a domestic flight or enter a federal building that requires ID.

The passport card was designed for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It contains the same biometric data as the passport book but in a smaller format. However, DHS does not recognize it as meeting the security standards required for Real ID compliance, even though it is a valid federal travel document for other purposes.

If you hold only a passport card and need to fly domestically after May 7, 2025, you will need to obtain a different form of Real ID — either a passport book, a Real ID-compliant driver's license, or another approved document.

Key Takeaways

  • The passport card does not count as Real ID, even though it is a valid U.S. travel document for land and sea crossings.
  • Only the full-size passport book meets Real ID requirements for domestic flights and federal building access.
  • Starting May 7, 2025, you must show Real ID-compliant identification to board a domestic flight or enter certain federal facilities.
  • If you have only a passport card, you can obtain a passport book, a Real ID-compliant driver's license, or another approved document to comply with the requirement.
  • A passport card remains valid for travel to Canada, Mexico, Bermuda, and the Caribbean by land or sea.

Why the passport card does not meet Real ID standards

Real ID is a federal security standard set by the Department of Homeland Security. It requires that identification documents contain specific security features, be issued by a state or federal agency following strict verification procedures, and be machine-readable in a standardized way. The passport book meets all these requirements and is on the official list of Real ID-compliant documents.

The passport card, while issued by the U.S. State Department and containing security features, was not designed to meet the Real ID technical specifications. DHS has not added it to the list of compliant documents. The reason is partly practical: the card's smaller size and different format do not align with the scanning and verification systems that airports and federal buildings use to check Real ID compliance.

This does not mean the passport card is invalid or insecure. It straightforward means it was created for a different purpose — convenient travel to nearby countries — and does not fit the Real ID framework.

What documents do count as Real ID

The documents that meet Real ID requirements include the U.S. passport book, passport card for travel to Canada, Mexico, Bermuda, and the Caribbean by land or sea (note: this is different from Real ID compliance), a Real ID-compliant driver's license, a Real ID-compliant state ID card, a military ID, a Trusted Traveler card (such as Global Entry or NEXUS), a permanent resident card, and a tribal ID issued by a federally recognized tribe.

Most people obtain Real ID compliance through their state's driver's license or ID card. To get one, you visit your state's DMV with proof of identity, proof of Social Security number, and proof of residency. The process takes a few weeks to a few months depending on your state. Some states charge a fee for a Real ID-compliant license; others do not.

If you already have a passport book, you already have a Real ID-compliant document and do not need to obtain anything else for domestic travel or federal building access.

How to upgrade from a passport card to a passport book

If you hold a passport card and want to use a passport book for Real ID compliance, you can explore for a passport book through the U.S. State Department. You will need to submit Form DS-11 (process for a U.S. Passport) or Form DS-82 (U.S. Passport Renewal process) depending on whether you are renewing an existing passport or explore for the first time.

The process typically takes 6 to 8 weeks for routine service or 2 to 3 weeks for expedited service. Expedited service costs extra. You will need to appear in person at a passport acceptance facility or passport agency if you are explore for the first time or if your passport book has expired for more than five years.

If you already have a valid passport book that expired within the last five years, you can renew by mail using Form DS-82, which is faster and cheaper than explore in person.

Real ID requirements for domestic flights

Beginning May 7, 2025, the Transportation Security Administration (TSA) will require all passengers to present Real ID-compliant identification at airport security checkpoints for domestic flights. This applies to all U.S. citizens and lawful permanent residents. If you do not have Real ID-compliant identification, you will not be allowed to pass through security, even if you have a valid passport card.

The passport card does not meet this requirement. You will need to bring a passport book, a Real ID-compliant driver's license, a military ID, or another document on the approved list. TSA agents will check your document at the checkpoint before you enter the security line.

If you are flying before May 7, 2025, a passport card is still accepted because the important date has not yet passed. However, it is wise to obtain Real ID-compliant identification now rather than waiting until the last moment, as demand for passport books and Real ID licenses typically increases as the important date approaches.

Real ID requirements for federal buildings

Federal buildings that require visitor identification — such as federal courthouses, Social Security Administration offices, and some federal office buildings — will also require Real ID-compliant identification starting May 7, 2025. A passport card will not be accepted at these facilities.

The specific buildings and offices that enforce this requirement vary by location and agency. Some federal buildings have always required ID; others are implementing the requirement for the first time. If you plan to visit a federal building, contact the specific office ahead of time to confirm what identification they accept.

Military bases, federal prisons, and certain other find federal facilities have their own identification requirements and may not accept standard Real ID documents. Check with the facility directly before your visit.

Frequently Asked Questions

Can I use my passport card to fly domestically after May 7, 2025?

No. After May 7, 2025, TSA will require Real ID-compliant identification for domestic flights. A passport card does not meet this requirement. You will need a passport book, a Real ID-compliant driver's license, or another approved document.

Is a passport card still valid for travel to Mexico and Canada?

Yes. A passport card remains valid for land and sea travel to Canada, Mexico, Bermuda, and the Caribbean. It is not valid for air travel to these countries — you need a passport book for that. The Real ID requirement applies only to domestic flights and federal building access within the United States.

How long does it take to get a passport book if I already have a passport card?

Routine service takes 6 to 8 weeks. Expedited service takes 2 to 3 weeks and costs extra. If your passport book expired within the last five years, you can renew by mail, which is faster and cheaper than explore in person.

What if I get a Real ID-compliant driver's license instead of a passport book?

A Real ID-compliant driver's license works just as well as a passport book for domestic flights and federal building access. Visit your state's DMV with proof of identity, Social Security number, and residency. The process typically takes a few weeks to a few months depending on your state.

Do I need Real ID if I have a military ID?

No. A military ID is Real ID-compliant and can be used for domestic flights and federal building access. You do not need to obtain additional identification.
