Step-by-step verification

  • Check the passport expiration date before buying nonrefundable travel.
  • Open the destination's official entry or travel-advisory page.
  • Confirm whether the rule is valid through entry date, departure date, or months after travel.
  • Check blank-page, visa, transit, and nationality-specific requirements.
  • Renew early if the official requirement is unclear or close to your travel dates.

What can differ

  • Rules can differ by nationality, destination, route, visa type, and transit airport.
  • Children's passports can have shorter validity than adult passports.
  • Some airlines may refuse boarding even if a traveler thinks the destination will allow entry.

FAQ

Do all countries require six months on a passport?

No. Some do, some do not, and the date rule can differ. Check the official destination rule.

Does a visa override passport validity?

No. A visa or ETA does not usually fix a passport that fails the validity rule.

Should I renew if my passport is close to expiring?

If the destination or airline requirement is close, renewal is usually safer than relying on a borderline interpretation.
