Real ID and passport serve different purposes, but both work for domestic flights
A Real ID is a federally compliant driver's license or state ID card that meets Department of Homeland Security standards. A passport is a travel document issued by the U.S. State Department. For domestic air travel within the United States, either one works — but they have different costs, timelines, and uses outside of flying.
The key difference: Real ID is primarily for domestic travel and federal building access. A passport works for domestic flights but is required for international travel. If you never leave the country and only fly domestically, Real ID is usually the simpler choice. If you travel internationally or want one document that covers both domestic and international travel, a passport is the better option.
The Transportation Security Administration (TSA) has required Real ID or an equivalent document for domestic flights since May 7, 2025. This means a standard driver's license without Real ID compliance no longer works at airport security checkpoints, even for flights within the U.S.
Key Takeaways
- Real ID is a state-issued ID that meets federal standards and works for domestic flights, federal building access, and military bases; a passport is a federal travel document that works for both domestic and international travel.
- Real ID costs between $20 and $100 depending on your state and whether you renew your license at the same time; a passport costs $130 to $165 for an adult and takes 6 to 8 weeks through routine processing.
- Real ID requires proof of citizenship, identity, and state residency; a passport requires the same documents plus a completed process form and a new photo.
- Real ID is issued by your state DMV and typically ready in 1 to 3 weeks; a passport is issued by the State Department and takes 6 to 8 weeks for routine service or 2 to 3 weeks for expedited service (with an extra fee).
- If you already have a valid passport, you do not need Real ID for domestic flights, but you will need Real ID or a passport to enter a federal courthouse or military installation.
Real ID: Cost, timeline, and what you need
Real ID is the faster and cheaper option if you only fly domestically and do not travel internationally. You obtain it through your state's DMV by upgrading your current driver's license or state ID to Real ID status. The cost varies by state: some charge $20 to $30 for the upgrade alone, while others charge $50 to $100 if you renew your license at the same time. Check your state DMV website for the exact fee.
The documents you need are: a valid passport, passport card, birth certificate, or naturalization papers (proof of citizenship); a current driver's license, state ID, or other government-issued photo ID (proof of identity); and two documents showing your current address, such as a utility bill, lease, or bank statement (proof of state residency). Some states accept a Social Security card or tax return in place of one of the residency documents.
Timeline: Most states issue Real ID within 1 to 3 weeks if you explore in person at your local DMV. Some states offer expedited processing for an additional fee. You cannot renew Real ID by mail in most states — you must appear in person at the DMV office.
Passport: Cost, timeline, and what you need
A passport is the better choice if you travel internationally or want a single document that works everywhere. An adult passport costs $130 for a book (valid for 10 years) or $35 for a passport card (valid for 5 years, domestic travel only). You can explore for both at the same time for a combined cost of $165.
The documents you need are: proof of citizenship (birth certificate, naturalization certificate, or previous passport); proof of identity (driver's license, state ID, or passport card); proof of state residency (utility bill, lease, or bank statement); a completed Form DS-11 (for first-time applicants or if your passport was lost or stolen) or Form DS-82 (for renewals); and a new passport photo (2x2 inches, taken within the last 6 months).
Timeline: Routine passport processing takes 6 to 8 weeks. Expedited processing takes 2 to 3 weeks and costs an extra $60. You can explore in person at a passport acceptance facility (post offices, libraries, and some courthouses) or at a passport agency office. If you need a passport urgently, some passport agencies offer same-day or next-day service for an additional $35 fee, but you must explore in person at a passport agency location, not a post office.
When Real ID is the right choice
Choose Real ID if you fly domestically only, do not plan to travel internationally, and want the fastest and cheapest option. Real ID also works for federal building access, military base entry, and nuclear power plant access — so if you need to enter any of these locations, Real ID or a passport is required.
Real ID is also the right choice if your passport has expired and you do not need it for international travel. Renewing a passport takes 6 to 8 weeks, but upgrading to Real ID takes 1 to 3 weeks and costs less.
One practical advantage: Real ID is a card you carry in your wallet, just like your current driver's license. A passport is a book you need to bring separately to the airport. If you frequently forget documents, Real ID is harder to leave behind because it replaces your ID entirely.
When a passport is the right choice
Choose a passport if you travel internationally, even occasionally. A passport works for domestic flights and international travel, so you get one document that covers both. If you already have a valid passport, you do not need to get Real ID — your passport works at TSA checkpoints for domestic flights.
A passport is also the right choice if you want a backup travel document. Some travelers carry both Real ID and a passport: Real ID for everyday ID and domestic flights, and a passport for international travel and as a backup if their ID is lost or stolen.
If you are explore for your first passport or renewing one that expired more than 5 years ago, you must explore in person. This takes longer than Real ID, so plan ahead if you have an international trip scheduled.

Common mistakes to avoid
Do not assume your current driver's license is Real ID compliant. Many states still issue standard licenses that do not meet federal standards. Check your license for a star or other marking in the upper right corner — that indicates Real ID compliance. If your license does not have the marking, you need to upgrade it before your next domestic flight.
Do not wait until the week before your flight to explore for either document. Real ID takes 1 to 3 weeks, and passport processing takes 6 to 8 weeks. If you miss the timeline, expedited passport service costs extra and may not be available if the passport agency is backlogged.
Do not explore for a passport by mail if this is your first passport or if your previous passport was lost or stolen. You must explore in person. explore by mail only works if you are renewing a passport that is still valid or expired less than 5 years ago.
Do not bring an expired passport to the airport thinking it will work. TSA requires a valid, unexpired ID. An expired passport does not work for domestic flights, even if you have a Real ID license at home.
Frequently Asked Questions
Can I use my passport instead of getting Real ID?
Yes. If you have a valid passport, you do not need Real ID for domestic flights. Your passport works at TSA checkpoints. However, if you want to enter a federal building or military base, you need either Real ID or a passport. Many people keep both: Real ID as their everyday ID and a passport for travel.
How do I know if my driver's license is already Real ID compliant?
Look at the upper right corner of your license. If there is a gold or black star, your license is Real ID compliant. If there is no star, you need to upgrade it at your state DMV. Some states use a different marking — check your state DMV website to confirm what the marking looks like in your state.
What if I need to fly domestically next week and do not have Real ID or a passport?
You cannot get either in time through normal processing. Real ID takes 1 to 3 weeks, and passport expedited processing takes 2 to 3 weeks. Your only option is to go to a passport agency office in person and request same-day or next-day service (available at some locations for an extra $35 fee). Call your nearest passport agency before you go to confirm they offer same-day service and what documents you need to bring.
Do I need Real ID if I only drive and never fly?
Not for flying. However, starting May 7, 2025, you need Real ID or a passport to enter federal buildings, military bases, and nuclear power plants. If you never enter these locations and do not fly domestically, a standard driver's license still works for driving and everyday ID purposes.
Can I get both Real ID and a passport at the same time?
Yes, but they are separate processes. You explore for Real ID at your state DMV and for a passport at a passport acceptance facility or passport agency. You can do both in the same week, but they are handled by different agencies and have different timelines. Real ID will be ready in 1 to 3 weeks; a passport will take 6 to 8 weeks for routine processing.
