The 12 documents every adult should have scanned and backed up

Most "important documents" articles tell you to scan thirty things. Forty. Sometimes fifty. The list is correct. It's also why nobody does it. You read the list, feel briefly virtuous, close the tab, and a year later you're still digging through a shoebox for a passport copy at 11pm before a flight.

So this is the short version. Twelve documents. The ones that, if missing the night before something important, will turn a stressful evening into a panicked one. Scan these and you've handled most of the risk. The other eighteen on the longer list are nice-to-haves you can knock out later.

Quick framing before the list: scanned means a clear, edge-to-edge phone photo or PDF that's actually readable when zoomed in. Backed up means the file lives somewhere you can find it from a different device — not just buried in your camera roll between holiday photos and screenshots of memes.

1. Your passport (photo page and visa pages)

The scenario: you're abroad, your wallet and passport are gone, and you need to walk into your embassy. A clear scan speeds up everything that follows — police report, emergency travel document, replacement application. The embassy staff still has to verify you, but a passport scan turns a four-hour ordeal into a one-hour one.

Scan the photo page plus any pages with stamps or visas. If you have multiple passports (some people do), scan all of them.

2. Driver's license or national ID

The day your wallet goes missing, the first thing a bank, mobile carrier or rental company asks for is photo ID. Replacement of the physical card might take weeks. A scan gets you most of the way through any "prove who you are" conversation that doesn't require the original.

3. Birth certificate

You'll go decades without thinking about your birth certificate. Then one day you'll need it for a passport renewal, a name change after marriage, opening a bank account in a new country, enrolling a child in school, or settling an estate. Getting a replacement copy from a vital records office can take 6 to 12 weeks. A scan saves you that wait.

4. Marriage certificate (or divorce decree)

Less ceremonial than it sounds. You'll need it for joint mortgages, joint tax filings, name changes, immigration paperwork, and unfortunately also for separation or estate proceedings. If you've been divorced, scan the decree — it proves the marriage ended and is required for any future legal filing where marital status matters.

5. Your most recent tax filing

Applying for a mortgage, a personal loan, a rental property, a credit increase, a visa, a new bank account — almost all of them will ask for the last year or two of tax filings as proof of income. Scan the full submitted return, not just the cover page. Banks often want to see the supporting schedules too.

6. Health insurance card (both sides)

The card you'll need at the worst possible moment. Snap both sides — the policy number on the front, the helpline numbers on the back. If you cover dependents, include their cards. If you have separate dental or vision insurance, those too.

7. Vaccination records

For yourself, especially for children. Schools, employers, embassies and clinics will ask for this at moments that are usually not convenient — the day before a school year starts, an hour before a flight, the morning of a new job. Many clinics no longer keep paper records past a few years, so a personal scan is sometimes the only copy that survives.

8. A list of your bank and investment accounts

Not the statements (those are too detailed). Just a one-pager: bank name, account type, last 4 digits, branch contact number. Same for retirement accounts, brokerage accounts, and crypto wallets if you have any. This document doesn't exist anywhere by default — you have to create it. It's also the single most useful thing your family will find if something happens to you.

9. Property deed or current lease agreement

Proof that you live where you say you live. Banks, governments, insurance companies, and schools all ask for it. If you own, scan the deed and title insurance documents. If you rent, scan the current lease. Update the scan when you renew.

10. Vehicle title and registration

If you own a car, the title is the document that proves it. Theft, fire, or an insurance claim will all require it. Same with the registration card. Keep the physical originals in a fireproof location, but the scan is what you'll actually pull up when you need it.

11. Will and power of attorney

If you don't have one, that's a different conversation. If you do, scan it. Make sure at least one trusted person knows where the original is and that a scanned copy exists. The same applies to advance medical directives — they're useful precisely in moments when nobody can ask you where you put the paperwork.

12. An emergency information sheet

This is the document most people skip and most regret skipping. One page. Contains: your blood type, allergies, current medications, primary doctor's number, two emergency contacts, your insurance policy number. Print one copy and put it in your wallet. Scan another. If you're ever unconscious in an emergency room, this is the page that does the talking for you.

How to actually do this in one weekend

The reason most people never finish is they imagine sitting down at a flatbed scanner for hours. You don't need a scanner. Your phone is better than a scanner now — Apple's built-in document scanner (Notes app, or the iOS Files app) detects edges, deskews, and exports as PDF in about three seconds per page.

Start with Tier 1 — items 1 through 4 above. These are the identity documents. They take fifteen minutes total. Most people stop there and never come back. That's fine: you've done the most important 30 percent of the work.

If you have another half hour: Tier 2 — items 5 through 8. Money and ownership. Add another half hour and you finish Tier 3, the health items.

The supporting paperwork — utility accounts, transcripts, warranties — can wait. They're useful, but losing them isn't a 3am crisis.

Where to keep the files

Wherever you keep them, the test is: can you find a specific document in 60 seconds from a different device? If the answer is "I'd have to scroll through 12,000 camera roll photos," you haven't actually backed anything up — you've just delayed losing it.

Three options that work, in rough order of effort:

• A dedicated folder in your phone's Files app. Free, lives on your device, syncs to iCloud Drive if you want a backup. Downside: documents mixed with everything else, no real organisation, searching is brittle.
• An encrypted cloud folder. Dropbox, Google Drive, iCloud with Advanced Data Protection — all give you syncing and findability. Downside: your documents now live on someone else's server, indexed by their systems. Acceptable for some people, a non-starter for others.
• A dedicated app for important documents. Which is what we're building. filedup is a private document organiser for iPhone — documents stay on your device, never uploaded, never trained on. We launch soon. If that sounds useful, join the waitlist.

The point isn't perfection

Most people who start a project like this aim for total coverage on day one, get overwhelmed, and quit. Twelve documents is achievable in a weekend by anyone. It also handles the worst-case scenarios — lost wallet abroad, stolen passport, hospital emergency, sudden tax audit, a death in the family.

If you scan nothing else this year, scan these twelve. The other eighteen on the long list can wait until you feel like it. The peace of mind you get from knowing the worst case is covered is worth the hour it took.

Now go open your scanner.
