How to Use the Passport 6-Month Validity Rule Checker
It's easy to assume a passport with just a few months left is still fine to travel on, but many countries actually require your passport to remain valid for at least 6 months beyond your entry date. Travelers who don't know this rule sometimes get turned away right at the airline check-in counter before they ever board the plane. This checker takes your travel date and passport expiration date and tells you instantly whether you meet the common 6-month standard.
The 6-month rule traces back to guidance from the International Civil Aviation Organization (ICAO) along with individual countries' own immigration policies, and it exists to prevent travelers from being stuck abroad with a passport that expires mid-trip. Airlines are often required to enforce this rule on behalf of the destination country, which means you can be denied boarding at your departure airport even before immigration ever sees your passport — so it's worth confirming well before your trip rather than discovering the problem at the gate.
Not every country applies exactly 6 months; some only require your passport to be valid through your planned stay, and a few use a 3-month standard instead. This checker applies the widely used 6-month benchmark, so for your exact destination, always double-check the specific requirement with that country's embassy or official immigration website before booking.
Frequently Asked Questions

No. Requirements vary by country, and some only require validity through your planned length of stay rather than a full 6 months. Always confirm the exact requirement with the destination country's embassy or official immigration site before you travel.
