Understanding Real ID Requirements for Domestic Air Travel
As of May 7, 2025, the federal government requires all air passengers to present an acceptable form of identification at airport security checkpoints for domestic flights within the United States. This requirement, known as the Real ID Act, applies to anyone 18 years or older boarding a commercial airplane for travel within the country.

The Real ID Act was passed by Congress in 2005 following recommendations from the 9/11 Commission. The law set new security standards for state-issued driver's licenses and identification cards. These standards ensure that identification documents meet certain federal requirements for authentication and security features. States have gradually implemented these standards over the years, and by May 2025, the TSA (Transportation Security Administration) requires all domestic air travelers to carry either a Real ID-compliant document or an acceptable alternative.
Real ID-compliant documents include a star or logo in the upper right corner of the card. This marking indicates that the document was issued according to federal standards. Not all states issued Real ID-compliant cards on the same timeline. Some states began offering them as early as 2009, while others took longer to implement the requirements. If you're unsure whether your current state ID or driver's license meets Real ID standards, you can check the card itself for the star marking or contact your state's Department of Motor Vehicles.
The Real ID requirement applies to all airports in the United States, including small regional airports and major hubs. This means whether you're traveling from a large city airport or a smaller local airport, you'll need to present acceptable identification at the TSA checkpoint. The requirement applies to all domestic flights, regardless of flight duration or distance traveled.
Practical Takeaway: Check your current driver's license or state ID card for the star or logo in the upper right corner. If you don't see it, contact your state's Department of Motor Vehicles to learn whether your card is Real ID-compliant or what steps you need to take to obtain one.
Acceptable Forms of Identification for Domestic Flights
The TSA accepts several forms of identification for domestic air travel, giving travelers multiple options beyond just a Real ID-compliant driver's license. Understanding what documents are accepted can help you prepare for your trip and avoid delays at the airport.

Real ID-compliant driver's licenses and identification cards from any U.S. state or U.S. territory are the most common form of acceptable identification. These documents must display the star marking and must not be expired. You can use a Real ID card from any state, not just the state where you're traveling from or to, as long as it was issued by a state or territory and meets federal standards.
If you don't have a Real ID-compliant document, the TSA maintains a list of other acceptable documents. These include passports (U.S. passports, U.S. passport cards, and passport books), military identification cards (including military dependent ID cards), tribal identification cards issued by federally recognized tribes, commercial driver's licenses with HAZMAT endorsement, and permanent resident cards (Green Cards). Additionally, documents issued by the U.S. government such as employee identification cards for federal employees are acceptable at TSA checkpoints.
For travelers younger than 18 years old, no identification is required for domestic air travel, though the TSA recommends bringing identification anyway. Children traveling with an adult can simply board with the accompanying adult, who will need to present acceptable identification.
It's important to note that expired identification is generally not accepted at TSA checkpoints for domestic flights. If your Real ID-compliant driver's license or ID card has expired, you'll need to renew it before your flight. Many states allow you to renew identification online or through the mail, which can be faster than visiting a DMV office in person. Some states also offer extended validity periods for certain age groups or circumstances.
Practical Takeaway: Make a list of the acceptable documents you currently have at home (passport, military ID, etc.). If none of these are available, visit your state's DMV website to learn about obtaining a Real ID-compliant driver's license or identification card and how long the process typically takes.
State-by-State Real ID Compliance Status and How to Obtain One
All 50 states, U.S. territories, and Washington D.C. now offer Real ID-compliant documents to their residents. However, the process for obtaining one varies by location, and some states charge fees while others don't. Understanding your specific state's process can help you obtain a Real ID document before your travel plans.

To obtain a Real ID-compliant driver's license or identification card, you'll generally need to visit your state's Department of Motor Vehicles office in person. Most states do not allow you to renew or obtain a Real ID through mail-only services, since the process requires in-person verification and document inspection. During your visit, you'll need to provide proof of identity, proof of Social Security number, and proof of residence. These requirements exist across all states, though the specific documents accepted may vary slightly.
Proof of identity typically includes your current driver's license, passport, or birth certificate. Proof of Social Security number can be your Social Security card, W-2 form, or tax return. Proof of residence can include a utility bill, lease agreement, mortgage statement, or bank statement with your current address. Some states accept additional documents, so it's worth checking your state's DMV website for the complete list.
The cost of obtaining a Real ID-compliant document varies by state. Some states charge a higher fee for Real ID documents compared to standard identification, while others charge the same amount for both. Fees typically range from $20 to $50, depending on the state and whether you're renewing or obtaining a new card. Processing times also vary—some states can issue a Real ID document within 1-2 weeks, while others may take 4-6 weeks or longer during busy periods.
If you need a Real ID document quickly, many states offer expedited processing for an additional fee. Some states also allow you to request an interim document while your permanent Real ID card is being processed, which can be used at TSA checkpoints temporarily. Checking your state's DMV website for current processing times and options can help you plan accordingly.
Practical Takeaway: Visit your state's Department of Motor Vehicles website and note the required documents for obtaining a Real ID, the current processing time, and the cost. Gather your proof of identity, Social Security number, and residence documents, then schedule an appointment at your local DMV office (if required by your state).
Using a Passport as an Alternative to Real ID
If obtaining a Real ID-compliant driver's license is inconvenient or takes too long, a valid U.S. passport is an excellent alternative for domestic air travel. Passports are accepted at all TSA checkpoints for domestic flights and have several advantages over driver's licenses for frequent travelers.

A U.S. passport book (the traditional booklet format) or passport card (a wallet-sized document) are both acceptable forms of identification for TSA security checkpoints on domestic flights. The passport book is more commonly known and widely recognized, but the passport card is more convenient to carry due to its smaller size. Both documents must not be expired to be used at TSA checkpoints. An expired passport cannot be used for domestic air travel identification, though expired passports can sometimes be renewed more quickly than new passport applications.
The process for obtaining a U.S. passport differs from obtaining a Real ID. You'll need to apply at a passport acceptance facility, which includes post offices, libraries, courthouse, or dedicated passport agencies in major cities. For a new passport, you'll need to apply in person with proof of citizenship (such as a birth certificate), proof of identity, a photo, and payment. The standard processing time for a new passport is typically 6-8 weeks, though expedited processing is available for an additional fee if you need it within 2-3 weeks.
One advantage of a passport is that it's useful for international travel as well as domestic air travel. If you travel internationally at all, having a passport means you have a document that works for both domestic and international trips. Passports are also valid for 10 years (for adults), which is longer than many state driver's licenses, though they may cost more upfront.
If you already have a passport that's expired, you may be able to renew it by mail or through a renewal application, which is faster and less expensive than applying for a new passport. However, if your passport expired more than
