U.S. passports expire on a fixed schedule: every 10 years for anyone issued a passport at age 16 or older, and every 5 years for children under 16.1U.S. Department of State. Frequently Asked Questions about Passport Services The exact expiration date is printed on the data page of the passport book. That date isn’t always the deadline that matters for travel, though, because many countries won’t let you in unless your passport stays valid for months beyond your trip.
The 10-Year and 5-Year Rules
If you were 16 or older when your passport was issued, it lasts 10 years from the issue date. If you were under 16, it lasts 5 years.1U.S. Department of State. Frequently Asked Questions about Passport Services
Passport cards follow the same schedule: 10 years for adults, 5 years for children. A card only works for land and sea travel between the U.S. and Canada, Mexico, Bermuda, and Caribbean countries. It can’t be used for international air travel.1U.S. Department of State. Frequently Asked Questions about Passport Services
Children’s passports run on the shorter cycle because kids change so much in a few years that the photo stops being useful for identification. That shorter window catches families off guard, especially when a passport was issued for a baby or toddler and everyone assumes it’s still good years later.
Why the Printed Date Isn’t Your Real Deadline
Even if your passport hasn’t technically expired, many countries refuse entry unless it stays valid for at least six months beyond your arrival or departure date. This “six-month rule” is one of the most common reasons travelers get turned away at the gate or denied boarding. Not every country measures it the same way. Some count six months from entry, others from your planned departure. Check the State Department’s country information pages for every destination on your itinerary.
Blank pages matter too. Most countries require at least one blank visa page in your passport, and some require two or three, particularly if they issue a full-page visa rather than a small entry stamp. Running low on empty pages is reason enough to renew early, even if the expiration date is still years away.
Put those two rules together and the practical shelf life of a 10-year passport is closer to nine and a half years for a frequent international traveler, and the shelf life of a 5-year child’s passport is closer to four and a half.
When to Renew Before a Trip
The safest approach is to renew about nine months before any planned international trip. Standard processing runs 4 to 6 weeks, and expedited processing runs 2 to 3 weeks.2U.S. Department of State. Processing Times for U.S. Passports Those estimates don’t count the days your application spends in the mail on the way to the agency and on the way back. Add roughly a week on each end if you’re mailing rather than renewing online.
A nine-month window leaves room for routine processing, a corrected photo if the first one is rejected, and the six-month validity buffer many destinations require. If you cut it closer than that and something goes wrong, you can end up scrambling for a last-minute appointment at a regional passport agency, which is limited to travelers whose departure is within 14 days, or within 28 days if a foreign visa is also needed.3Travel.State.Gov.

How Adult Renewal Works
Adults have two routine paths: renewal by mail using Form DS-82, or online renewal through the State Department’s website. Mail renewal is available if you still have your passport, it’s undamaged, it was never reported lost or stolen, it was issued within the last 15 years, you were 16 or older when it was issued, and it’s in your current legal name (or you can document a name change).4U.S. Department of State. Renew Your Passport by Mail
Online renewal is narrower. Your passport has to have been issued for 10 years and be either expiring within the next year or expired less than 5 years ago; you have to be 25 or older; you can’t be changing your name, sex, or other personal information; you can’t be traveling internationally for at least 6 weeks from your submission date; you have to be inside a U.S. state or territory when you submit; and the passport can’t be damaged or have been reported lost or stolen.5U.S. Department of State.

If you miss any of the mail-renewal criteria, you’ll apply in person using Form DS-11 as a first-time applicant would, which adds both time and an in-person acceptance fee.
Children Can’t Renew — They Reapply Every Time
A child’s passport can’t be renewed by mail or online. Every time a child under 16 needs a new passport, you apply in person using Form DS-11, the same form used for first-time applicants.4U.S. Department of State. Renew Your Passport by Mail
Both parents or legal guardians generally must appear in person with the child and present their own identification. You’ll also need documentation of the parental or guardian relationship, such as a birth certificate listing both parents. If one parent can’t attend, there’s a specific procedure involving a notarized consent form, and skipping that step can derail the appointment.
Because of the 5-year cycle plus the six-month validity buffer, a passport issued to a 3-year-old is realistically usable for international travel until around age 7 and a half, not age 8.
Situations That End a Passport Early
A lost or stolen passport can’t be renewed. It has to be replaced with a brand-new application: Form DS-64 to report the loss or theft, plus Form DS-11 to apply in person for a replacement.
Damaged passports follow the same in-person path. The State Department considers a passport damaged if it has water damage, a significant tear, unofficial markings on the data page, missing or torn-out visa pages, or a hole punch. Normal wear — a bent spine from being carried in a pocket, or visa pages fanning out from frequent use — doesn’t count.1U.S. Department of State. Frequently Asked Questions about Passport Services For genuine damage, you submit the damaged passport, a signed statement explaining what happened, and a full DS-11 application.
A legal name change doesn’t shorten a passport’s life, but it does affect how you renew. For a mail renewal, you include a marriage certificate, a divorce decree that specifically grants you use of a former name, a court-ordered name change, or a certificate of naturalization issued in your new name; the document must show both your former and current names.4U.S. Department of State.

The Bottom Line on Timing
The printed expiration date tells you the legal lifespan: 10 years for adults, 5 for kids. The real renewal deadline is earlier. If you travel internationally, treat any passport with less than nine or ten months of remaining validity as one that needs renewing soon, and treat a child’s passport as needing replacement well before the printed date. Check the expiration on every passport in your household once a year, and check it again before you book any international trip.
