The six-month passport rule · 🇵🇹 Portugal

Does your passport meet Portugal's rule?

Portugal needs your passport valid at least 3 months beyond the day you leave, or you can be refused boarding. Check yours below.

Portugal requires your passport to be valid for at least 3 months beyond your intended departure. Schengen also requires the passport to have been issued within the last 10 years on the day you enter.

Your passport dates are checked in your browser and never sent anywhere.

Entry rules change without notice and airlines make the final call — verify with your carrier or the destination's embassy before you fly.

The rule, in one minute

Immigration authorities want a buffer on your passport in case you overstay, fall ill, or get stranded. So instead of asking "is it valid today?", many ask "will it still be valid six months from now?" — and your airline enforces the answer at check-in, because carriers are fined for flying in passengers who get turned away.

But "the six-month rule" is really three different rules:

Six months from entry
The most common form — Thailand, Indonesia, China, India, the UAE and most of Southeast Asia and East Africa. Your passport must be valid six months past the day you arrive.
Three months beyond departure
The Schengen area's version — plus a second clause people miss: the passport must have been issued within the last ten years when you enter.
Valid for the stay
The UK, US, Canada, Japan, Australia and much of the Americas only require validity through your trip — though a thin margin still invites questions.

What this means for your Portugal trip

For a trip arriving August 15, 2026 and leaving August 29, 2026, Portugal needs your passport valid until November 29, 2026 — 3 months beyond the day you leave.

Questions travelers actually ask

Is it six months from arrival or from departure?

Depends on the destination. Most six-month countries count from your date of entry; a few count from your intended departure. Schengen counts three months from departure. The checker above uses the right anchor for each destination.

What if my passport expires in exactly six months?

You're on the line, and airline agents apply these rules conservatively. Anything under a month of margin should be treated as a renewal trigger, not a pass.

Who actually enforces this — the country or the airline?

Usually the airline, at check-in, against the industry Timatic database. Most travelers caught by the rule never reach immigration — they're stopped at the departure airport, where no amount of arguing changes the database's answer.

Does the rule apply to connections and layovers?

If you stay airside in international transit, usually not. If you must clear immigration to change terminals or re-check bags, the transit country's rule can apply. Your final destination's rule is checked at first check-in regardless.

Do children's passports follow the same rule?

Yes — and they're the ones that catch families out, because child passports expire in five years instead of ten. Check every passport in the household, not just yours.

Why is Schengen's rule different?

The Schengen Borders Code asks for three months of validity beyond your departure from the area, and for the passport to have been issued within the previous ten years on the day you enter.

How early should I renew?

Start at nine months remaining. You stay clear of every six-month rule while the renewal processes, and most countries issue the new passport with its own full validity, so you rarely lose time by renewing early.

My passport meets the rule — am I guaranteed entry?

No. Validity is one requirement among several (visas, blank pages, onward tickets, proof of funds). This site checks the validity rule only.

Where does this site's data come from?

Each destination's rule is encoded from its embassy or immigration-authority guidance and reviewed periodically — the verdict shows the source and review date. Rules change without notice; your airline has the final word.

Check the rule for a specific country

The six-month rule isn't the same everywhere. Open your destination for its exact requirement, the anchor date it counts from, its source and when it was last reviewed — with the checker already pointed at that country.
