The flights are booked, the group chat has a name, and you're already deep in lists of restaurants you can't pronounce. Then a quieter thought surfaces: where, exactly, is your passport? And is it… fine?
That thought deserves one evening, soon. Every document on this list is easy to fix months out and miserable to fix at the airport. Here's the whole checklist, roughly in order of how badly each one can ruin the trip.
Start with the passport — it has the longest lead time
Everything else on this list can be fixed in days. A passport takes weeks, which is why it goes first, on the day you book.
Find it (actually find it — "a drawer, probably" doesn't count), open the data page, and check the expiration date against the six-month rule: many countries require your passport to stay valid six months past your arrival or departure. A passport that expires four months after you land can get you denied boarding before you ever leave home. The full details — where the date is, renewal timelines, why kids' passports sneak up on families — are in our guide to checking your passport's expiration date.
If the date is anywhere near the danger zone, start the renewal now and read the rest of this list while you wait.
Visas: check even if you've "never needed one"
Visa-free doesn't mean paperwork-free anymore. A growing number of destinations that never asked for anything now want an electronic travel authorization applied for online before you fly — cheap and usually fast, but not something you can do standing at the gate.
So look it up per trip, even for countries you've visited before:
- Check the official government or embassy site of your destination — not a third-party "visa service" that appears above it in search results.
- Note whether approval is instant or takes days, and whether you need a printed confirmation.
- If you have a layover, check the transit country too. Some require a transit authorization even if you never leave the airport.
Save the confirmation email or PDF the moment it arrives. Future-you, in a customs line, will be grateful.
Insurance and health paperwork
Travel insurance is one of those documents that matters exactly once — and in that moment you'll want three things findable fast: the policy number, the 24-hour emergency assistance phone line, and what's actually covered (medical care abroad and evacuation are the parts worth reading twice; check whether your regular health insurance covers you overseas at all — many US plans don't).
Some destinations also want proof of vaccination — yellow fever is the classic example for parts of Africa and South America — and your doctor may recommend others depending on where you're headed. Check requirements early, because some vaccines need to be done weeks before travel to count. Then make sure the proof itself is somewhere better than a shoebox: here's how to keep vaccination records on your iPhone so the card is with you even when the paper isn't.
Copies, kept apart from originals
This is the cheapest insurance on the list. If your passport is lost or stolen abroad, a copy of the data page turns a multi-day embassy ordeal into a much shorter one.
The rule is simple: copies travel separately from originals.
- A paper copy of your passport data page and visa in your luggage, not in the same bag as the passport.
- A digital copy you can open without internet — saved to your phone itself, not sitting in an email you'd need Wi-Fi to fetch.
- One full set left with someone at home who answers their phone.
The same set belongs in your digital emergency binder anyway — a trip is just the deadline that finally makes you build one. This is also where Paperlock quietly earns its keep: photograph the passport, the visa, the insurance card once, and they live encrypted on your phone behind Face ID — openable in a foreign police station with zero bars, and findable later by just asking ("show my travel insurance"). It's how the whole app works, and it's coming soon to iPhone.
The numbers you hope you never dial
Five minutes of copying-and-pasting before you leave:
| Keep handy | Why |
|---|---|
| Your embassy or consulate at the destination | Lost passport, arrest, serious emergency |
| Insurer's emergency assistance line | Medical help and pre-approval abroad |
| Bank and card-loss numbers | Freezing cards works better before the thief shops |
| One contact at home | The person holding your spare document set |
| Where you're staying, written down | Immigration forms ask; jet lag deletes it |
Put these somewhere that works offline. A note on your phone is fine; a copy in your document vault is better; a folded paper in your bag never runs out of battery.
Traveling as a family? Multiply everything
Every item above, times each traveler — and kids add wrinkles of their own. In the US, children's passports last only five years, so they expire out of sync with the adults', usually unnoticed. Infants need their own passport; there's no riding on a parent's. And if a child is traveling with one parent, or with grandparents, some countries ask for a notarized consent letter from the absent parent — check your destination's embassy site well ahead, because notarizing something the night before a flight is nobody's favorite errand.
The efficient version: one evening, every passport on the table, every date checked against the six-month rule, every data page photographed. The earliest expiration in the family, minus six months, is your real deadline.
The one-evening version
Booked the trip today? Then tonight: find the passports, check the dates, look up visa and vaccination requirements on official sites, and photograph everything. That's it — maybe forty minutes, most of it spent finding the passports.
Everything after that is genuinely the fun part.
