Which document you need depends on what you're using it for
A driver's license and a passport are not interchangeable for Real ID purposes. A Real ID-compliant driver's license is what you need to board a domestic flight or enter a federal building. A passport works for international travel and some federal purposes, but it is not a state-issued ID and does not replace a driver's license for everyday identification.
If you drive, you will eventually need a Real ID-compliant driver's license or state ID card — that is the document your state's DMV issues. A passport is a separate federal document issued by the U.S. Department of State. The two serve different purposes, and most people end up carrying both.
Key Takeaways
- A Real ID-compliant driver's license is issued by your state's DMV and is required to board domestic flights or enter federal buildings after the important date.
- A passport is a federal document issued by the State Department and works for international travel, but does not replace a state ID for domestic purposes.
- You can use a passport to board a domestic flight even without a Real ID-compliant license, but you cannot use a driver's license for international travel.
- Getting a Real ID-compliant license requires visiting your DMV in person with specific documents; a passport requires a separate process to a passport acceptance facility.
- Both documents have expiration dates and renewal processes, and both cost money — neither is free.
When you need a driver's license instead of a passport
You need a Real ID-compliant driver's license or state ID card if you drive, rent a car, or want to board a domestic flight using your state-issued ID. After the federal important date, TSA will not accept a standard driver's license at airport security — only a Real ID-compliant one, a passport, a military ID, or a few other federal documents.
For everyday purposes — buying alcohol, proving your age, renting an apartment, opening a bank account — your state's driver's license is the standard form of ID. A passport is not practical for these situations because you would carry it everywhere and risk losing it.
If you do not drive, you can get a Real ID-compliant state ID card instead of a license. It serves the same purpose for federal buildings and domestic flights, but it does not authorize you to drive.
When a passport works for federal purposes
A passport is a valid form of ID for boarding domestic flights and entering federal buildings, even if your driver's license is not Real ID-compliant. This is one of the few domestic situations where a passport substitutes for a state ID.
However, a passport is primarily for international travel. If you need to leave the country — by air, sea, or land to Canada, Mexico, or the Caribbean — you must have a valid passport. A driver's license, no matter how compliant, will not work at an international border.
A passport also works as a backup form of federal ID if your driver's license is lost, expired, or suspended. But carrying a passport daily for domestic purposes is not practical, and replacing it if lost is more difficult and expensive than replacing a driver's license.
Documents you need and where to get them
To get a Real ID-compliant driver's license or state ID, you visit your state's DMV in person. You will need to bring an original or certified copy of your birth certificate, a Social Security card or document showing your number, proof of your current address, and a completed process form. Your state's DMV website lists the exact documents it accepts — some states take a passport as proof of citizenship, while others do not.
To get a passport, you visit a passport acceptance facility — usually a post office, library, or courthouse in your area. You need an original or certified birth certificate, a completed passport process form (DS-11 or DS-82 depending on whether you are renewing), a government-issued photo ID, and a passport photo taken to specific requirements. You also pay a fee.
Both processes require you to appear in person. You cannot mail in an process for a new passport or a first-time Real ID license. Renewals sometimes allow mail-in options, but the rules vary by state and by document type.
How long each takes and what it costs
A Real ID-compliant driver's license usually takes two to four weeks to arrive by mail after your DMV appointment, though some states offer expedited processing for an extra fee. The cost varies by state — typically between $20 and $60 for a license renewal or new ID card.
A passport takes longer. Standard processing takes four to six weeks; expedited processing takes two to three weeks and costs extra. A new passport book costs around $130 for an adult, plus a $35 execution fee at the acceptance facility. A passport card (a smaller, wallet-sized version valid for land and sea travel to Canada, Mexico, and the Caribbean, but not air travel) costs less but takes the same amount of time.
Both documents expire — a driver's license typically after four to eight years depending on your state, and a passport after ten years for adults. Plan ahead if either is expiring soon, because processing times can back up during peak travel seasons.
Real ID compliance and passport status
A passport is always federally compliant for domestic flights and federal buildings — you do not need to check whether it is "Real ID-compliant" the way you do with a driver's license. The Real ID requirement applies only to state-issued IDs like driver's licenses and state ID cards.
If your driver's license was issued before your state began issuing Real ID-compliant licenses, or if you have not yet renewed it, your current license may not meet the federal standard. Your state's DMV can tell you whether your license is compliant, or you can check your license itself — Real ID-compliant licenses usually display a star or other marking in the upper right corner.
If you are unsure whether you have time to get a Real ID-compliant license before the important date, a passport is a valid backup. However, obtaining a passport takes weeks, so do not wait until the last moment.
Renewing and replacing each document
Renewing a driver's license often allows you to mail in your process and old license, though some states require an in-person visit every few years. The cost and timeline are similar to getting a new one. If your license is lost or stolen, you must visit the DMV in person to request a replacement, and it usually arrives within two to four weeks.
Renewing a passport by mail is possible if your passport is not damaged, was not issued when you were under 16, and you still have it in hand. You mail in your old passport, a completed renewal form, a new passport photo, and the fee. Processing takes four to six weeks standard or two to three weeks expedited. If your passport is lost or stolen, you must explore in person for a replacement, which is treated as a new process and takes longer.
Replacing a lost or stolen passport is more complicated and expensive than replacing a lost driver's license, so keeping your passport in a safe place at home — not in your wallet — is worth the inconvenience.
Frequently Asked Questions
Can I use my passport instead of getting a Real ID license?
Yes, for boarding domestic flights and entering federal buildings. However, you still need a driver's license or state ID for everyday identification, renting a car, and driving. Most people end up carrying both because they serve different purposes.
Do I need both a passport and a Real ID license?
If you drive and travel internationally, yes. If you only drive domestically, a Real ID license is enough. If you do not drive but travel internationally, you need a passport and a state ID card for federal buildings and domestic flights.
What happens if I only have a passport and no driver's license?
You can board domestic flights and enter federal buildings with your passport. However, you cannot legally drive, and many everyday situations — renting an apartment, opening a bank account, buying alcohol — expect a state-issued ID. You would need to get a state ID card from your DMV.
Which document should I renew first if both are expiring?
Renew your driver's license first if you drive regularly, because losing the ability to drive affects your daily life when ready. A passport can wait a few weeks if you do not have international travel planned. However, if you have a flight booked before your license renewal will arrive, renew the passport first so you have a backup for TSA.
Can I use an expired passport for domestic flights?
No. TSA requires a valid, unexpired form of ID. An expired passport will not work, and neither will an expired driver's license. Both must be current to use them for federal purposes.
