The two passport rules for travel to Europe, and why they get confused

One rule looks at when your passport was issued. The other looks at when it expires. They are measured from different days, they fail independently, and almost every story about somebody being turned away at a European airport comes down to treating them as a single rule.

What GOV.UK actually says

The entry requirements on GOV.UK's country pages for Schengen destinations are worded almost identically wherever you look. France, Germany and Spain all say that your passport must:

The France page adds a clarification that settles the argument outright: the expiry date does not need to be within 10 years of the date of issue. That single line is the confirmation that these are two separate tests rather than one rule expressed twice.

Rule one: the date of issue

This is the rule people have never heard of, and the one most likely to cost them a flight. It asks a question about the age of the document: was it issued less than 10 years before the day you arrive?

For any passport issued today the answer is automatically yes, because a passport valid for 10 years reaches its expiry date and its tenth birthday on the same day. The problem is confined to a specific group of documents. Before 10 September 2018, when you renewed a passport early, HM Passport Office added the remaining months from the old one to the new one, up to a maximum of 9 months. A passport issued that way can run 10 years and 9 months from issue to expiry.

GOV.UK's France page puts the consequence plainly: if you renewed your passport before 1 October 2018, it might have a date of issue that is more than 10 years ago, making it invalid for entry to the Schengen area. The passport is not fake and it has not expired. It simply fails a test that has nothing to do with the expiry date.

Those passports are now working through the last of their life, since even a passport issued in September 2018 with the full 9 months added expires in mid-2029 and passes its tenth birthday in 2028. Until then, if your passport was issued in 2018 or earlier, the issue date is the number to check first.

Rule two: the expiry date

The second rule asks whether the document has enough life left in it, and the measurement runs from the day you plan to leave the Schengen area rather than the day you enter it.

That detail changes the answer for longer trips. Someone flying out on 1 May and returning on 8 May needs an expiry date on or after roughly 8 August. Someone spending ten weeks travelling and leaving the Schengen area on 15 July needs an expiry date on or after roughly 15 October. Same passport, same departure date, different verdict.

It is also worth noticing that the rule refers to leaving the Schengen area, not leaving the first country you land in. A trip that runs France to Italy to Slovenia is one continuous stay for this purpose, and the date that counts is the day you leave the area altogether.

A passport can pass one and fail the other

The checker on this site runs both tests at once for a chosen destination, which is the quickest way to find out which one, if either, is the problem.

Where the rules apply

These are Schengen area rules, and the Schengen area currently has 29 members: 25 EU member states plus Iceland, Norway, Switzerland and Liechtenstein. Bulgaria and Romania became full members on 1 January 2025. Cyprus is an EU member state that has not yet joined the Schengen area, and Ireland has an opt-out from the Schengen rules.

Ireland sits outside all of this. GOV.UK is explicit that although Ireland is in the EU, it is not part of the Schengen area and Schengen rules do not apply. British and Irish citizens continue to travel freely under the Common Travel Area, and a British national is not legally required to show a passport to enter Ireland, although carriers set their own identification requirements and some now insist on one.

For non-Schengen countries elsewhere in Europe, and for the rest of the world, check the entry requirements page for the specific destination on GOV.UK. A six month requirement is common outside Europe, but it is neither universal nor a substitute for reading the country's own rules.

The separate 90 day limit

Validity is not the only thing counted at a Schengen border. British citizens can visit without a visa for up to 90 days in any 180 day period, and visits to Schengen countries in the 180 days before you travel count towards that total. Since 10 April 2026 the Entry/Exit System records entries and exits digitally instead of stamping passports, which means the count is now automatic rather than something a border officer works out from ink.

What to do before you book

• Read both dates off the personal details page and write them down rather than working from memory.
• Check the issue date first if the passport was issued in 2018 or earlier.
• Measure the expiry rule from your planned departure from the Schengen area, not from your arrival.
• Read the entry requirements for your destination on GOV.UK, because they are updated and this page is not the source.
• Leave a margin. Meeting a rule by three days is technically compliant and practically uncomfortable, particularly if plans slip.
