Passport validity rules for travel: what agencies should check before booking

Short answer: for the Schengen area a passport must be valid for at least 3 months after the traveler leaves, and issued within the previous 10 years. Many other destinations ask for 6 months of validity beyond the trip, and airlines enforce whatever the destination requires — they can refuse boarding at the gate. Both checks take one minute with the passport in hand, which is why they belong at booking time.

A rejected passport is one of the few problems an agency can fully prevent and almost never fix later. The traveler has the document, you have the trip dates, and the destination’s rule is public. Still, passports fail at check-in every day, because the check happened too late or never happened. This page collects the rules that matter for small agencies and a routine to run before you take payment.

We make Viaondo, and our free passport validity checker runs the arithmetic for one trip in a few seconds; the rules below are what the check applies. Nothing here is about visas — a valid passport does not mean a visa is not needed, and the two checks are separate.

What are the Schengen passport validity rules?

The Schengen Borders Code sets the entry conditions for travelers from outside the EU in Regulation (EU) 2016/399, Article 6(1)(a): the passport’s validity must extend at least three months after the intended date of departure from the Member States’ territory, and the document must have been issued within the previous 10 years. Border officers may waive the three-month rule in a justified emergency — that waiver exists for genuine emergencies, not for bookings that could have been checked.

The 10-year rule catches people who renewed early. GOV.UK’s entry requirements for Spain explain the practical case: a passport renewed before 1 October 2018 may carry extra months beyond 10 years from its issue date, and those extra months do not count for Schengen entry. The expiry date printed on the cover can look comfortably valid while the document fails the issue-date test. When you check a client’s passport, read two dates — expiry and issue — not one.

The 3-month clock runs from the day the traveler leaves the Schengen area, not from arrival. A two-week trip planned in the final months of a passport’s life can pass or fail on the departure day alone. For the length-of-stay side of European trips, the 90/180-day rule calculator works the other half of the check.

Which destinations require six months of passport validity?

Outside the Schengen area there is no single European rule — each destination sets its own, and many converge on the same figure. The U.S. State Department’s passport FAQ states it directly: some foreign destinations require that a passport have at least 6 months of validity beyond the dates of the trip, and some airlines will not allow boarding when the requirement is not met.

The numbers really do differ per country. GOV.UK’s country pages, checked on the date in the table above, ask for an expiry date at least 150 days after arrival for Turkey, and at least 6 months after arrival for Thailand and Egypt. Two things follow for an agency:

• The number is not always 6 months, and it is not the same everywhere — Turkey’s margin runs from arrival, the Schengen rule runs from departure. The authoritative source for each destination is that country’s own entry rules, which is why the check has to be run per trip, not from memory.
• Airlines operationalize the requirement through Timatic, the database maintained by IATA that airlines, ground handlers and travel agents use for document requirements — over 700 million passenger document checks run through it each year. When check-in staff refuse a passport, Timatic’s rule for that destination is what they are applying.

What your agency should check before taking payment

Four lines, one minute, at booking time:

1. Expiry date vs the destination’s margin. Will the passport still be valid 3 months after the traveler leaves the Schengen area — or 6 months beyond the trip, where the destination asks for it?
2. Issue date. For Europe, was the passport issued within the 10 years before arrival? Renewals from before 1 October 2018 need a second look at GOV.UK’s country pages.
3. The whole party. Check every traveler, not the booker. Children’s passports expire fastest: in the U.S., a child’s passport is valid for 5 years and cannot be renewed, only replaced.
4. The trip’s own dates. Late changes push the departure out — and can push a once-valid passport over the line. Re-run the check when dates move.

Run the numbers with the passport validity checker, save the result with the trip, and you have a record that the check happened. For what you may store and for how long when you keep copies of client documents, see our guide on client passports and itinerary software under the GDPR. The same passport data feeds the EU’s ETIAS travel authorization: our ETIAS application guide covers what the application will ask for and how your agency may file it.

What to tell clients

One paragraph, ready to paste:

Before we finalize your booking, please send me a photo of the passport photo page for every traveler. I check each passport against your destination’s validity rules — 3 months after you leave Europe plus the 10-year issue rule for the Schengen area, and the six-month rule where the destination requires it. If anything is close, it is much better to find out now than at the airport.

If a passport is close to the line, the fix is time, not cleverness: renew before the trip. Renewal times vary by season and by country, so the safe move for a client with a borderline passport is to renew first and book after — an honest message that also protects your agency from holding money against a trip that cannot depart.

Where this lives in your workflow

The validity check is one of the boring checks that make an agency look flawless: passport validity, the 90/180-day count, local arrival times, documents in the traveler’s pocket. We build Viaondo so those checks live in one place — every trip’s dates, times and documents checked before you publish, and each client carries the whole trip in an app with your brand.
