The honest bit

Look for a UL classification: it means the box was tested to a fire standard for a set time and temperature. Big temperature claims without one are marketing. Keep digital copies too: Ready.gov suggests saving documents to the cloud.

Before you buy

Check what it's rated for: UL fire classifications state a time and temperature, and some boxes add a water rating.

Heavy safes protect well but can't be carried out in an evacuation; a portable bag can.

Many households use both.

Store copies, not just originals, and keep digital copies.

Know what goes in: insurance policies, IDs, deeds, bank and medical records.

How we choose

We verify every product's specifications against at least two independent sources, re-check its US price and stock on a schedule where we can track it automatically, and cross-check safety-relevant claims against official guidance. Every review is labelled Researched or Used and reviewed by us: where we've bought a product, or been sent it free, and used it ourselves, its review says which; where we haven't, our verdict is a considered spec-and-evidence comparison, not a hands-on test — and commissions never change a ranking either way.

Common questions

What documents should I keep in a fireproof safe?

Ready.gov lists copies of insurance policies, identification and bank account records, kept electronically or in a waterproof, portable container.

Are fireproof bags really fireproof?

Many bags make temperature claims without a UL fire classification. Treat them as heat-resistant; a UL-classified box is tested protection.

What does UL Classified 1/2 hour at 1550°F mean?

The box was tested to keep contents safe for 30 minutes at that temperature. Longer ratings give more protection.

Should I keep originals or copies?

Copies in your grab-and-go container, originals somewhere safe, plus digital copies.
