Passport expiry checker
A passport stops being useful for travel months before the date printed inside it. Enter your expiry date — or the country and issue date and let the tool work it out — to see the days left, the point it falls foul of the six-month rule, and when to start renewing. Nothing you type leaves your browser.
Work out your dates
What is the six-month passport rule?
The six-month rule is the requirement, used by many countries, that your passport stay valid for at least six months after you arrive. Because of it, a passport becomes unusable for those destinations roughly six months before its printed expiry date — the last stretch of validity is dead time for travel, even though the document still looks current.
The reason is administrative headroom: a border officer wants a margin in case a visit runs long or a return is delayed. Airlines enforce it at check-in on the destination's behalf, so a passport inside the window can mean being turned away at the gate, not just at the border.
When should I renew my passport?
Start about nine months before the expiry date. The usable window already closes at the six-month mark, and a renewal can take anywhere from a couple of weeks to a few months — longer in the run-up to summer. Beginning nine months out gives a slow renewal room to land before any trip is at risk.
That is the date the tool above labels “best to start renewing by.” It is a planning cushion, not a deadline set by any government; the true constraint is the six-month rule plus however long your issuing authority currently takes.
Which countries enforce the six-month rule?
Many do, and the list is long enough that it is safer to assume six months and check the exceptions than the other way round. A great many countries in Asia, the Middle East and Africa require six months of remaining validity; others require three months; a handful require only that the passport be valid for the stay.
The Schengen area is the common exception travellers trip over: it asks for validity of at least three months beyond your intended departure, and that the passport was issued within the previous ten years. Because these rules change and are enforced by the airline as well as the border, confirm the current requirement for your specific destination with its embassy or your carrier before you book.
Where Sparky fits
This checker is free to use and needs no account. If it is useful to be reminded before the window closes, the tool can email you once, six months ahead — the same job Sparky Fetch does for a whole household's documents, quietly, in the background.
Sparky is a private, AI document archive: you forward or upload a passport, a lease, a tax slip, and it reads each one, files it, and answers questions like “when does my passport expire” across the family. It is in private beta, so the honest framing is an invite and a live demo — a fictional family's paperwork you can poke at without signing up.
Frequently asked questions
How many months before it expires does a passport stop working for travel?
For many destinations, six months. A large number of countries — across Asia, the Middle East and elsewhere — require at least six months of validity remaining on the day you enter, so a passport becomes unusable for those trips about six months before the date printed inside it. The Schengen area is stricter in one sense and looser in another: three months beyond your intended departure, and issued within the last ten years. Always confirm the exact rule with your airline or the destination's embassy.
How long does a passport renewal take?
It varies by country and by season, from a couple of weeks to a few months, and processing times lengthen before summer and holidays. Most issuing authorities offer a faster paid track. Because the usable window already closes six months before expiry, starting about nine months out leaves room for a slow renewal without grounding a trip. Check current processing times on your own government's passport pages.
Do you store my passport number?
No. The calculator runs entirely in your browser — nothing about your passport is sent to us, and there is no passport-number field. If you ask for a reminder, the only things stored are the email address you type and the expiry date the reminder is set for.
Is this immigration or legal advice?
No. It is general travel-document information to help you plan a renewal. Entry rules differ by destination and change without notice, so confirm the current requirement with the destination's embassy or your airline before you book or travel.
Will you email me?
Only if you ask. Enter your email and we send one confirmation now and, later, a single reminder six months before your expiry date. Every email has a one-click unsubscribe link, and the address is never used for anything else.
