Why this site exists

Every summer, thousands of travellers are turned away at airport check-in because their passport doesn't meet the destination's validity rules. Most never knew the "6-month rule" existed. Passport 6 Month Rule was built to fix that — a free, fast checker plus plain-English guides so you find out before you book, not at the gate.

Who runs it

The site is independently owned and run by David Mansion, founder of Mansion Web Company. David personally researches, writes and updates the country pages and guides. There is no large content team — and no sponsored content masquerading as advice.

How we research the rules

Every country's passport validity rule on this site is checked against the destination government's own border or immigration site, the UK Foreign, Commonwealth & Development Office travel advice, the US State Department's country information, and IATA Timatic where available. Where airlines apply their own stricter rule, we note it.

How we make money

We don't charge readers for the checker or guides. Costs are covered by:

• Display advertising via Google AdSense.
• A small commission on a handful of travel-related affiliate links (visa services, travel insurance, flight search). We only link to services we'd happily use ourselves, and the commission never changes what we recommend.
