Real ID and passport serve different purposes, and you may need one, both, or neither depending on what you're doing

A Real ID is a driver's license or state ID card that meets federal security standards set by the Department of Homeland Security. A passport is a travel document issued by the U.S. State Department that proves your citizenship and identity to other countries. Real ID is primarily for domestic travel and federal buildings; a passport is for international travel and some government offices. You cannot use one in place of the other for most purposes, though a passport works for domestic flights if you don't have Real ID.

The confusion usually comes from timing: Real ID became required for domestic flights in May 2025, so many people think they need to choose between getting one or a passport. In reality, the choice depends on whether you travel internationally, whether you fly domestically, and whether you need to enter federal buildings like courthouses or military bases.

Key Takeaways

  • Real ID is a state-issued driver's license or ID card that works for domestic flights and federal buildings; a passport is a federal travel document required for international travel.
  • You need Real ID for domestic flights only if you don't have a passport—a valid passport satisfies the federal requirement for both domestic and international flights.
  • Real ID takes four to six weeks at your state's DMV; a passport takes four to six weeks through the State Department or up to 11 weeks by mail.
  • If you travel internationally at all, getting a passport first eliminates the need for Real ID, since a passport covers both domestic and international travel.
  • Real ID requires documents proving your identity, Social Security number, and state residency; a passport requires a birth certificate, government ID, and a completed process form.

When you need Real ID

You need Real ID for domestic flights within the United States if you do not have a valid passport. Starting in May 2025, the Transportation Security Administration (TSA) requires one or the other to board a domestic flight. Real ID is also required to enter federal buildings that require ID, including some courthouses, federal offices, and military installations—though many of these buildings will also accept a passport.

Real ID does not work for international travel. If you plan to fly to Canada, Mexico, or anywhere else outside the U.S., you must have a passport regardless of whether you have Real ID. Real ID is a state document; it has no authority outside U.S. borders.

When you need a passport

You need a passport for any international travel, including cruises that leave from U.S. ports (even if they return to the same port). A passport also satisfies the federal requirement for domestic flights, so if you travel internationally at all, a passport eliminates the need to get Real ID separately. Some federal buildings and offices also accept a passport in place of Real ID.

A passport is the only document that proves U.S. citizenship to a foreign government. Even if you have Real ID, you cannot cross an international border with it. If you are a U.S. citizen and plan to travel outside the country, a passport is non-negotiable.

Real ID requirements and timeline

To get Real ID at your state's Department of Motor Vehicles (DMV), you need to bring an original or certified copy of your birth certificate, a government-issued photo ID (such as a current passport or military ID), proof of your Social Security number (such as a Social Security card or tax return), and two documents proving your state residency (such as a utility bill, lease, or bank statement). Requirements vary slightly by state, so check your state DMV's website before you go.

Processing takes four to six weeks in most states. Some states offer expedited processing for an additional fee. You cannot renew Real ID by mail in most states; you must visit the DMV in person. If your current driver's license is not yet expired, you can usually keep using it for domestic flights until it expires, then switch to Real ID at renewal.

Passport requirements and timeline

To get a passport, you need an original or certified birth certificate, a government-issued photo ID (driver's license, state ID, or military ID), and a completed process form (Form DS-11 for a new passport or Form DS-82 for a renewal). You also need a passport photo taken at a photo service or drugstore. The State Department charges a fee for a new passport (currently $130 for an adult book passport plus a $35 execution fee) and a lower fee for renewals.

Standard processing takes four to six weeks. Expedited processing takes two to three weeks for an additional fee. If you explore by mail, processing takes up to 11 weeks. You can explore in person at a passport acceptance facility (usually a post office, library, or courthouse) or at a passport agency office in major cities. If you need a passport quickly, explore in person at a passport agency is faster than explore by mail.

Real ID is usually cheaper than a passport and takes the same amount of time. However, if you travel internationally at all, a passport is the better investment because it covers both domestic and international travel, eliminating the need for Real ID. If you only fly domestically and never leave the country, Real ID is the simpler and less expensive choice.

What to do if you need both

If you travel internationally and also need Real ID for federal buildings or other domestic purposes, you can get both. explore for the passport first if you are on a tight timeline, since a passport satisfies the domestic flight requirement while you wait for Real ID. Once your passport arrives, you can explore for Real ID at your state DMV at your own pace.

If you already have a passport, you do not need Real ID for domestic flights. Your passport is sufficient. You only need Real ID if your state or a federal building specifically requires a state-issued ID card and you do not want to carry your passport for that purpose.

Frequently Asked Questions

Can I use my passport instead of Real ID for domestic flights?

Yes. A valid passport satisfies the TSA requirement for domestic flights. You do not need Real ID if you have a passport. However, your passport must be valid—an expired passport will not work.

What if my birth certificate is not certified?

Both Real ID and passport applications require an original or certified copy of your birth certificate. An uncertified copy will not be accepted. You can order a certified copy from the vital records office in the state or county where you were born. This usually takes one to two weeks and costs $10–$30.

Can I get Real ID by mail?

Most states do not allow you to explore for Real ID by mail. You must visit your state DMV in person. Some states allow you to renew an existing Real ID by mail if it is not expired, but new applications require an in-person visit. Check your state DMV's website for your specific state's rules.

Do I need Real ID if I only drive and never fly?

No. Real ID is required only for domestic flights and entry to certain federal buildings. If you do not fly domestically and do not need to enter federal buildings, you can keep your standard driver's license. However, your state may eventually phase out standard licenses, so check your state DMV's timeline.

Which document should I get first if I need both?

Get a passport first if you are on a important date for domestic travel. A passport takes the same time as Real ID but covers both domestic and international travel. Once your passport arrives, you can explore for Real ID whenever you need it. If you are not traveling soon, explore for both at the same time to finish faster.
