Passport validity rules: the 6-month rule, the EU’s 10-year rule and how to check

Why an in-date passport can still get you turned away

Many countries want your passport to stay valid for some time after you arrive or leave, so that you aren’t left stranded with an expired document if your trip runs late. The US State Department says many countries require at least 6 months’ validity remaining to enter, and that passengers won’t be allowed to board an international flight if they don’t have the validity their destination requires.

That last point matters most: the airline checks your passport at check-in, and if it doesn’t meet the rules, you won’t fly. Under UK passenger rights, an airline can refuse boarding for inadequate travel documents without paying compensation, as our guide to denied boarding explains.

Passport validity by destination

These are the rules for British and American passport holders on official government pages, checked in November 2026. They’re a starting point, not a substitute for checking your own destination.

The EU and Schengen rules for British passports

Since the UK left the EU, British passport holders are treated as non-EU nationals, and the Schengen Borders Code applies. GOV.UK’s travel advice for EU countries such as France says your passport must meet two conditions on the day you travel: it must have been issued less than 10 years before the date you arrive, and its expiry date must be at least 3 months after the day you plan to leave. Both conditions apply; meeting one isn’t enough.

The 10-year rule catches people out. Before October 2018, the UK added up to 9 extra months to a new passport if you renewed before the old one expired. GOV.UK warns that passports renewed before 1 October 2018 may have an issue date more than 10 years ago, so a passport with an expiry date well in the future can still fail the rule. Look at the issue date on the photo page, not only the expiry date.

The same rules apply to US citizens visiting the Schengen area: the State Department says your passport must be valid for at least 3 months beyond your planned departure, and recommends having 6 months. The EU’s new Entry/Exit System registers non-EU travellers at the border but doesn’t change these validity rules; our EES and ETIAS guide has the details.

Travelling to the US and the UK

For British citizens visiting the US, GOV.UK says your passport must be valid for the length of your planned stay. You also need an approved ESTA or a visa before you fly, and a valid ESTA doesn’t guarantee entry. GOV.UK reminds travellers to check the rules for any country they transit too, since many countries require 6 months’ validity. Our guide to the ESTA and the UK ETA explains both systems.

For Americans visiting the UK, you need a passport valid for your whole stay and, under the UK’s Electronic Travel Authorisation scheme, an ETA approved before you travel (GOV.UK says US nationals are covered). Flying New York to London or London to New York, check both documents well before departure.

Countries with a 6-month rule

The 6-month rule isn’t universal, but it’s common, especially in Asia, Africa and the Middle East. GOV.UK says the UAE requires 6 months from the date you arrive, and Thailand requires 6 months from arrival along with a blank page. If you’re only transiting the UAE without passing through immigration, GOV.UK says 3 months from the transit date is enough.

Some countries set 6 months only as a recommendation. The State Department, for example, recommends 6 months for France and Germany while the legal requirement is 3 months after departure. Our advice: if your passport has less than 6 months left, check every country on your route, including transit stops, before you book.

How to check and renew in time

Do this as soon as you start planning, not the week before you fly.

1. 1Find your passport’s issue date and expiry date on the photo page
2. 2Look up your destination on GOV.UK foreign travel advice (UK passports) or travel.state.gov (US passports), under entry requirements
3. 3Check the rules for any country where you change planes, too
4. 4Check that you have enough blank pages: Thailand, for example, requires at least one
5. 5If you’re close to a limit, renew before you book, and allow for processing times shown on GOV.UK or travel.state.gov
6. 6Once you have a new passport, update the number in any ESTA, ETA or airline booking: an ESTA is linked to a specific passport
