The core difference: what each document proves and where you can use it
A passport proves your citizenship and identity to foreign countries. A Real ID is a driver's license or state ID card that meets federal security standards set after 9/11. They serve different purposes, and you may need one, both, or neither depending on what you're doing.
If you're flying domestically within the United States, you can use either a passport or a Real ID. If you're entering a federal building, a military base, or traveling internationally, the rules differ. The confusion usually comes from the fact that both work for domestic flights, but they're not interchangeable for everything else.
Real ID became mandatory for domestic air travel on May 7, 2025. Before that date, a regular driver's license worked. After that date, the TSA will only accept a passport, a Real ID, a military ID, or a handful of other federal documents at airport security checkpoints.
Key Takeaways
- A Real ID is a state-issued driver's license or ID card with enhanced security features; a passport is a federal document proving citizenship and used for international travel.
- For domestic flights after May 7, 2025, you need either a Real ID, a passport, a military ID, or a tribal ID — a regular driver's license no longer works.
- Getting a Real ID takes 1 to 3 weeks at your state's DMV and requires proof of citizenship, residency, and identity; a passport takes 4 to 12 weeks through the State Department.
- If you travel internationally, you must have a passport; Real ID alone is not sufficient for any foreign country.
- You can have both documents at the same time, and many people do — they serve different needs and have different expiration dates.
When you need a Real ID and when a passport works instead
For domestic air travel, either document works. Walk up to the TSA checkpoint with a Real ID or a passport, and you're through. A regular driver's license stopped working on May 7, 2025.
For federal buildings, military bases, and nuclear power plants, you need a Real ID or a passport. A regular ID card will not get you past security. If you work in or frequently visit any of these locations, a Real ID is usually faster to obtain than a passport.
For international travel, you must have a passport. A Real ID will not work at any border crossing, airport departure gate, or customs checkpoint outside the United States. If you plan to travel to Canada, Mexico, the Caribbean, or anywhere else, a passport is required.
For everyday purposes — opening a bank account, voting, buying alcohol, renting a car — either a regular driver's license or a Real ID works. A passport is overkill for these situations.
How to get a Real ID at your state DMV
Visit your state's Department of Motor Vehicles website and check what documents they require. Most states ask for proof of citizenship (a birth certificate or passport), proof of residency (a utility bill or lease), and proof of identity (your current driver's license). Some states have additional requirements, so confirm before you go.
Bring the original documents or certified copies — photocopies usually don't count. You'll fill out an process form at the DMV, have your photo taken, and pay a fee that ranges from $10 to $30 depending on your state. Some states charge extra if you want a Real ID instead of a regular renewal.
Processing time varies by state. Most DMVs issue a Real ID within 1 to 3 weeks. Some states offer expedited service for an additional fee. You can check your state's DMV website for current wait times before you go.
Your Real ID will have a small star in the top right corner of the card. That star is what TSA agents look for at airport security. Without it, your driver's license won't work for domestic flights after May 7, 2025.
How to get a passport through the State Department
You can explore for a passport at a passport acceptance facility, which includes most post offices, libraries, and county clerk offices. Go to the State Department's website and find the nearest facility in your area.
Bring proof of citizenship (a birth certificate, naturalization certificate, or previous passport), proof of identity (a driver's license or Real ID), and proof of residency (a utility bill or lease). You'll also need a passport photo, which you can get at most pharmacies or passport facilities themselves.
Fill out Form DS-11 (for a new passport) or Form DS-82 (for a renewal) at the facility. Pay the process fee, which is $130 for an adult passport book plus a $35 execution fee. Processing time is typically 4 to 12 weeks, though expedited service (1 to 3 weeks) costs an extra $60.
Your passport arrives by mail. Once it's in hand, it's valid for 10 years if you're an adult, or 5 years if you're under 16. You can use it when ready for international travel and domestic flights.
Cost and processing time comparison
| Document | Cost | Processing Time | Valid For | Works for Domestic Flights | Works for International Travel |
|---|---|---|---|---|---|
| Real ID (new) | $10–$30 (varies by state) | 1–3 weeks | 4–8 years (varies by state) | Yes | No |
| Real ID (renewal) | $10–$30 (varies by state) | 1–3 weeks | 4–8 years (varies by state) | Yes | No |
| Passport (standard) | $130 + $35 execution fee | 4–12 weeks | 10 years (adults) | Yes | Yes |
| Passport (expedited) | $130 + $35 execution + $60 expedite | 1–3 weeks | 10 years (adults) | Yes | Yes |
Should you get both, or just one?
If you fly domestically and never travel internationally, a Real ID is cheaper and faster. You'll spend $10 to $30 and wait 1 to 3 weeks. A Real ID is also easier to replace if you lose it — you just go back to the DMV.
If you travel internationally at all, you need a passport regardless. Many people get both because they serve different purposes. Your Real ID stays in your wallet for everyday use and domestic flights. Your passport stays at home in a safe place until you need it for a trip.
If you already have a passport, you don't need a Real ID for domestic flights — your passport works. But if your driver's license is expiring soon and you don't travel internationally, getting a Real ID at renewal time is simpler than carrying a passport everywhere.
If you travel internationally more than once a year, a passport is worth the cost and wait time. You'll use it repeatedly, and it's the only document that works at foreign borders.
What to do if you're traveling soon and don't have either
If you're flying domestically in the next few weeks and your driver's license is not a Real ID, you have three options: get a Real ID at your state DMV (1 to 3 weeks), get an expedited passport (1 to 3 weeks), or use a military ID, tribal ID, or other federal document if you have one.
Call your state DMV now and ask about wait times. Some states are backlogged and taking longer than the standard 1 to 3 weeks. If your DMV is backed up, an expedited passport might be faster — call a passport acceptance facility and ask.
If you're traveling in less than a week, you may not have time for either. Check with the TSA or your airline about what documents they'll accept in your specific situation. Some airlines have exceptions for people who have already started the process.
Frequently Asked Questions
Can I use my passport instead of a Real ID for domestic flights?
Yes. A passport works at TSA checkpoints for domestic flights just like a Real ID does. If you already have a passport, you don't need a Real ID for flying within the United States. However, a Real ID is more convenient for everyday use because you don't have to carry your passport around.
Do I need a Real ID if I have a passport?
No. A passport is sufficient for domestic flights and federal buildings. You only need a Real ID if you want to use your driver's license for those purposes. Many people keep their passport at home and use a Real ID for daily activities.
What happens if I try to fly with a regular driver's license after May 7, 2025?
The TSA will not accept it at the security checkpoint. You'll be turned away unless you have a Real ID, passport, military ID, or other accepted federal document. You won't be able to board your flight.
Can I renew my driver's license as a Real ID at the same time?
Yes. When your driver's license is expiring, you can renew it as a Real ID at the DMV. Bring the same documents you'd need for a new Real ID. The process is the same, and the cost is similar to a regular renewal in most states.
How long is a Real ID valid?
A Real ID is valid for 4 to 8 years, depending on your state. Check your state's DMV website for the exact validity period. When it expires, you'll need to renew it at the DMV just like a regular driver's license.
