Passports issued after 2018 are valid for exactly 10 years. But if your passport was issued before September 2018, it might be valid for up to 10 years and nine months. This is because, before 2018, the passport office would add up to nine extra months from your old passport to your new one.

This means some people have passports that haven’t officially expired and are still valid for travel worldwide. The exception is travel in Europe, where passports must be less than 10 years old.

To travel to Europe and Schengen countries, your passport must be:

• Issued less than 10 years before your departure date
• Valid for at least three months after your planned return date
