You should not carry your passport at all times. Inside the United States, a driver’s license or state ID handles daily identification, and your passport is safer locked away at home. The situations that actually require the original document are narrow and mostly involve crossing an international border or following a specific foreign country’s law while you are abroad.
At Home in the U.S., Leave It Locked Up
Nothing about ordinary American life requires a passport on your person. Driving, banking, buying alcohol, picking up a package, checking into a hotel, and boarding a domestic flight all work with other identification. The Transportation Security Administration accepts REAL ID-compliant driver’s licenses, state-issued photo IDs, U.S. military IDs, passport cards, and several other documents at airport checkpoints.1Transportation Security Administration. Acceptable Identification at the TSA Checkpoint
The one thing that changed recently: REAL ID enforcement began on May 7, 2025. If your driver’s license doesn’t have the star marking or say “Enhanced,” TSA will not accept it for domestic flights.2Transportation Security Administration. REAL ID A passport or passport card works as a substitute, but the better fix is upgrading your license so your passport can stay home.
TSA now also accepts mobile driver’s licenses at more than 250 checkpoints in roughly two dozen participating states and territories, through Apple Wallet, Google Wallet, Samsung Wallet, or state-specific apps.3Transportation Security Administration.

When You Actually Need the Original Passport
There are a handful of situations where nothing else substitutes.
International air travel. Every U.S. citizen boarding an international flight, whether departing or arriving, needs a valid passport book.4U.S. Customs and Border Protection. U.S. Citizens – Documents Needed to Enter the United States and/or to Travel Internationally A passport card, a driver’s license, or a photocopy will not get you on the plane.
Land and sea crossings to Canada, Mexico, the Caribbean, or Bermuda. Under the Western Hemisphere Travel Initiative, U.S. citizens can present a passport book, a passport card, an Enhanced Driver’s License, or a trusted traveler card like NEXUS or SENTRI.5U.S. Customs and Border Protection. Western Hemisphere Travel Initiative Any air trip to those same destinations still requires the full passport book.
Foreign countries that require you to carry it. Japan, Indonesia, Italy, and Turkey all have laws letting police stop foreign nationals and demand identification at any time. Failure to produce a passport or valid immigration document can result in fines or temporary detention, depending on the country. Check the State Department’s country information page for your destination before you go.
Formal transactions abroad. Opening a bank account, signing a lease, registering with local police during a longer stay, and completing legal paperwork overseas almost always require the original passport, not a copy.
Should You Get a Passport Card Instead?
If you frequently drive or take a ferry across the Canadian or Mexican border, a passport card is worth considering as a second document. It’s wallet-sized, cheaper than the book, and REAL ID-compliant for domestic flights and federal facility access.6U.S. Department of State. U.S. Passports and REAL ID What it does not do: international air travel, and it has no visa pages, so it won’t work for any trip requiring a visa stamp. Its use is limited to land and sea travel between the United States and Canada, Mexico, and the Caribbean.
Abroad: Carry a Copy, Lock Up the Original
This is the situation where people most often assume they need to have their passport on them. In countries that legally require it, you technically do. But carrying the original everywhere raises the odds of losing it, being pickpocketed, or damaging it, and replacing a passport abroad is a serious inconvenience.
The practical compromise is to carry a photocopy of the passport’s ID page and keep the original locked up. The State Department’s own travel guidance takes the same position: “While overseas, carry copies of your passport ID page and foreign visa with you at all times.”7U.S. Department of State. Smart Traveler Tips A photocopy won’t satisfy border control or formal government checks, but it will generally satisfy a police officer doing a routine identity check. And if the original does get stolen, having a copy speeds up the replacement process at the nearest U.S. embassy or consulate.
A workable setup abroad:
- Original passport in the hotel safe or another secure location at your accommodation.
- Photocopy of the ID page (and any visa) in your wallet or day bag.
- Digital scan stored in a secure cloud service or emailed to yourself, so you can pull it up from any device.
- A second copy with a trusted contact back home.
Take the original with you when you know you’ll need it — an internal flight, a hotel change, a bank appointment, a train ride that crosses a border — and put it back in the safe when you return.
Keeping It Safe When You’re Not Carrying It
At home, a fireproof safe or lockbox is the right place. While traveling, use the hotel room safe or a locked bag in your room. Do not leave your passport in a car glove compartment, a beach bag, or a jacket pocket in a crowd.
When you do need to carry the original, a money belt worn under your clothing or a neck pouch keeps it close to your body and out of sight. A front pocket beats a back pocket or a purse that can be unzipped in a crowd. Passport theft in tourist-heavy areas is common enough that these habits matter.
Physical condition matters too. Normal wear like slightly bent pages or a minor crease is fine, but water damage, a significant tear, missing visa pages, unofficial markings on the data page, and a hole punch all count as damage that requires replacement.8U.S. Department of State. Replacing Your U.S. Passport After a Disaster A border agent who sees serious damage can refuse the document.
If Your Passport Is Lost or Stolen
Report it to the State Department immediately. You can file Form DS-64 online through the State Department’s form filler, call 1-877-487-2778, or print and mail the form.9U.S. Department of State. Report Your Passport Lost or Stolen An online report cancels the passport within one business day, which prevents anyone else from using it for identity theft or fraudulent travel.
If you lose it inside the United States, apply for a replacement at a passport acceptance facility using Form DS-11. Routine processing takes four to six weeks, and expedited processing takes two to three weeks.10U.S. Department of State. Processing Times for U.S. Passports
If you lose it abroad, contact the nearest U.S. embassy or consulate.11USAGov. Lost or Stolen Passports Embassies can issue emergency passports, often within one to two business days for a complete application. This is where the photocopy and the digital scan earn their keep. Walking in with a copy of your ID page, a second form of photo ID, and a police report from the local authorities makes the process dramatically faster than arriving empty-handed.
