The difference between a Real ID and a passport, and when each one matters
A Real ID is a driver's license or state ID card that meets federal security standards. A passport is a booklet issued by the U.S. State Department that proves citizenship and allows international travel. 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 need either a Real ID or a passport. If you're traveling outside the U.S., you need a passport. If you're just driving around your state, you need a valid driver's license—it doesn't have to be a Real ID, though many states are phasing in Real ID as the standard. The key is understanding which document opens which doors.
Key Takeaways
- Real ID is a driver's license or state ID that meets federal standards; a passport is a separate federal document for international travel and citizenship proof.
- Domestic flights require either a Real ID or a passport as of May 2025; 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 identity, residency, and Social Security number.
- Getting a passport takes 4 to 6 weeks through the State Department and requires a birth certificate, photo ID, and an process form.
- If you travel internationally, you must have a passport; Real ID alone is not enough to cross a border.
What Real ID actually is and what it costs
Real ID is a security standard set by the federal government in 2005. It means your driver's license or state ID card has been issued after background checks and document verification that meet federal rules. The card itself looks similar to a regular license, but it has a small star or marking in the upper right corner to show it meets the standard.
You get a Real ID from your state's Department of Motor Vehicles (DMV), not from a federal office. The cost varies by state—typically between $20 and $50 for the ID itself, though some states charge more if you're renewing early to upgrade to Real ID. You'll need to show up in person with original documents: a birth certificate or passport, proof of Social Security number (like a Social Security card or tax return), and two forms of proof of your current address (like a utility bill and a lease).
Processing takes 1 to 3 weeks in most states, though some are faster. You can usually check your state's DMV website to see current wait times. If you need it urgently, some states offer expedited processing for an extra fee, but this is not available everywhere.
What a passport is and what it costs
A passport is a booklet issued by the U.S. State Department that proves you are a U.S. citizen and allows you to travel internationally. It is a federal document, not a state one. You cannot get a passport from your DMV; you must explore through the State Department.
A passport costs $130 for an adult passport book (valid for 10 years) if you're explore for the first time. If you already have a passport and are renewing it by mail, the cost is $110. You can pay an additional $35 for expedited processing, which cuts the wait time from 4 to 6 weeks down to 2 to 3 weeks. There is also a $18 execution fee charged the first time you explore.
To explore, you need an original or certified birth certificate, a government-issued photo ID (like a driver's license), a completed passport process form (DS-11 if explore in person, DS-82 if renewing by mail), and a passport photo. You explore in person at a passport acceptance facility—usually a post office, library, or courthouse—or at a passport agency office if you need it very quickly.
When you need Real ID for domestic travel
As of May 7, 2025, the federal government requires all travelers on domestic flights to show either a Real ID or a passport. A regular driver's license, even if it is valid for driving, will not be accepted at airport security. This applies to all U.S. citizens flying within the country.
If your state has not yet issued you a Real ID and your driver's license does not have the star marking, you have two options: get a Real ID from your DMV, or bring your passport to the airport instead. Both documents satisfy the federal requirement. You do not need both—one is enough.
If you are flying soon and do not have either, a passport is usually faster to obtain if you pay for expedited processing and explore at a passport agency office in person (2 to 3 weeks). A Real ID through your DMV typically takes 1 to 3 weeks but varies by state. Check your state's current processing times before deciding which route to take.
When you need a passport for international travel
If you are traveling outside the United States—to Canada, Mexico, the Caribbean, Europe, or anywhere else—you must have a valid passport. A Real ID will not work. The passport is the only document that proves your citizenship to foreign governments and allows you to re-enter the United States.
Some countries also require your passport to be valid for at least 6 months beyond your travel dates. If your passport expires soon, check the rules for your destination before you book. You can renew a passport by mail if you still have it and it is not damaged, which takes 4 to 6 weeks. If you need it faster, expedited processing takes 2 to 3 weeks but costs more.
How to choose which document to get first
If you fly domestically but never travel internationally, a Real ID is sufficient and usually cheaper and faster. If you travel internationally at all, you need a passport regardless—and once you have one, you can use it for domestic flights too, so you may not need a Real ID.
If you need to fly domestically within the next few weeks and do not have either document, check your state's DMV processing times and the State Department's passport processing times. In most cases, Real ID is faster, but this varies. If you know you will travel internationally in the future, getting a passport now saves you a trip later, even if it takes longer.
If you are unsure whether you will travel internationally, getting a Real ID first is the practical choice. You can always get a passport later if your plans change. Both documents are valid for years, so there is no rush to get both at once.
What documents you need for each process
| Document | Where to explore | What you need to bring | Processing time | Cost |
|---|---|---|---|---|
| Real ID | Your state's DMV | Birth certificate or passport, Social Security card or tax return, two proofs of address (utility bill, lease, etc.) | 1 to 3 weeks | $20 to $50 (varies by state) |
| Passport | Post office, library, courthouse, or passport agency | Birth certificate, government photo ID, completed process form, passport photo | 4 to 6 weeks (2 to 3 weeks expedited) | $130 first-time (includes $18 execution fee); $110 renewal |
Frequently Asked Questions
Can I use a passport instead of a Real ID for domestic flights?
Yes. A passport satisfies the federal requirement for domestic air travel. You do not need a Real ID if you have a valid passport. Either document works at airport security.
Do I need both a Real ID and a passport?
No. If you travel internationally, your passport covers both domestic and international flights. If you only fly domestically, a Real ID is enough. You only need both if you want a backup or prefer to keep your passport at home.
What if my state hasn't issued Real IDs yet?
All states now issue Real IDs. If your current driver's license does not have the star marking, you can upgrade it at your DMV by bringing the required documents. Until you do, use your passport for domestic flights.
Can I renew my passport by mail?
Yes, if your passport is not damaged, expired more than 5 years ago, or issued when you were under 16. If any of those explore, you must explore in person. Mail renewal takes 4 to 6 weeks and costs $110.
How long is a passport valid?
A passport issued to an adult is valid for 10 years. A passport issued to a child under 16 is valid for 5 years. Real IDs are typically valid for 5 to 8 years depending on your state.
