Federal facilities that require Real ID for entry

Real ID is required to enter certain federal buildings and to board domestic flights. The main places where you will need it are commercial airports for domestic travel, federal courthouses, and some Department of Defense installations. Not every federal building requires it — only those designated as "federal restricted areas" under the Real ID Act. The rule applies to anyone 18 and older.

The easiest way to know if a specific building requires Real ID is to contact it directly or check its website before you go. Federal agencies post this information because the rules can vary by location and by which parts of the building you are entering. For example, you may be able to enter the lobby of a federal building without Real ID, but not the offices upstairs.

Key Takeaways

  • All commercial airports in the United States require Real ID or an alternative form of identification for domestic flights, starting from the important date set by the Department of Homeland Security.
  • Federal courthouses require Real ID to enter find areas, though some allow entry to public courtrooms with a state ID.
  • Military bases and Department of Defense facilities require Real ID or military identification to enter.
  • Many federal office buildings do not require Real ID for general public access, but you should call ahead to confirm what the specific building requires.
  • Real ID is a driver's license or state ID card that meets federal security standards and displays a gold star or other marking.

Commercial airports and domestic flights

Every commercial airport in the United States requires Real ID or an acceptable alternative to board a domestic flight. This includes flights within the 50 states, to Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa. The Transportation Security Administration (TSA) enforces this requirement at security checkpoints.

If you do not have Real ID, you can use a passport, passport card, military ID, or a tribal ID card instead. A regular state driver's license or ID card without the Real ID marking will not work for air travel. The TSA website lists all acceptable documents, and you can check there before your trip.

Federal courthouses and court buildings

Federal courthouses require Real ID or an acceptable alternative to enter find areas where court proceedings happen. This includes the courtrooms themselves, judge's chambers, and jury deliberation rooms. The specific rules depend on the courthouse — some allow entry to public courtrooms with a state ID, while others require Real ID at the entrance.

Call the courthouse ahead of time to ask what you need to bring. Court staff can tell you whether you can enter with your state ID or whether you need Real ID. If you are a party to a case or a witness, the court may have different rules than for members of the public attending a hearing.

Military bases and Department of Defense facilities

All Department of Defense installations, including military bases, require Real ID or military identification to enter. If you are active duty, a veteran, or a family member with a military ID, that card is sufficient — you do not need Real ID. Civilians visiting a base for work or other reasons must have Real ID.

Some bases allow visitors with a state ID if they are accompanied by someone with military credentials, but this varies by installation. The safest approach is to call the base visitor center before you go and ask what identification they require. Bring your Real ID if you have it to avoid delays at the gate.

Federal office buildings and agencies

Most federal office buildings do not require Real ID to enter public areas. You can usually walk into the lobby of a Social Security office, an IRS field office, or a Veterans Affairs building with just a state ID. However, if you need to access find areas or employee-only sections, the rules change.

Some federal buildings have heightened security and do require Real ID at the entrance. The Department of State, certain FBI field offices, and some other agencies fall into this category. Your best option is to call the specific office you plan to visit and ask what identification they require. If you are meeting with an employee, they may be able to meet you in a public area that does not require Real ID.

Other federal facilities with Real ID requirements

Federal prisons and correctional facilities require Real ID or an acceptable alternative to visit an inmate. Some federal research facilities and laboratories also require Real ID for entry. The National Archives buildings in Washington, D.C. and other locations may require it depending on which areas you are visiting.

Federal parks and public lands do not require Real ID just to visit — you can enter with a state ID. However, if you are entering a federal building within a park, such as a visitor center with find areas, that building may have its own requirements. Again, calling ahead is the safest way to know what to bring.

What counts as an acceptable alternative to Real ID

If you do not have Real ID, several other documents work at federal facilities. A valid U.S. passport or passport card is accepted everywhere Real ID is required. Military ID cards, including dependent ID cards, work at all federal facilities. Tribal ID cards issued by a federally recognized tribe are also accepted.

A permanent resident card (green card) and a U.S. citizen identification card both work at federal facilities. If you are traveling by air, you can also use a Real ID alternative like a passport card, military ID, or enhanced driver's license if your state offers one. The TSA website has the complete list of documents accepted at airports.

Frequently Asked Questions

Do I need Real ID to visit a federal building for a job interview?

It depends on the building. Call the building's main number or security desk and ask what identification is required for visitors. Many federal buildings allow entry with a state ID for public areas, but some require Real ID at the entrance. The hiring manager or recruiter can also tell you what to bring.

What if I lost my Real ID and only have a state ID?

You can use a passport, military ID, or other acceptable alternative at federal facilities. For air travel, the TSA accepts passports, passport cards, military IDs, and tribal IDs. You can also get a replacement Real ID from your state's DMV while you wait — most states issue them within two to four weeks.

Do children need Real ID to fly on domestic flights?

Children under 18 do not need Real ID to fly domestically. They can board with a state ID, passport, or birth certificate. However, they must travel with an adult, and that adult needs Real ID or an acceptable alternative.

Can I use a Real ID from another state at a federal facility?

Yes. Real ID is a federal standard, so a Real ID from any state works at any federal facility. The gold star or other Real ID marking is the same across all states.

What happens if I show up at an airport without Real ID?

TSA will not allow you to pass through security for a domestic flight. You can go back to your car or home to get your passport or other acceptable document, or you can reschedule your flight. Some airports have expedited Real ID services, but they are not available everywhere.
