Labeling Cold Storage Backups Without Exposing Seed Material

When a miner calls us because they cannot find a backup, the problem is rarely cryptography. It is labeling. The metal card is in the right safe, but three identical envelopes sit beside it and nobody remembers which envelope belongs to which wallet.

Use location codes, not content descriptions

We recommend a three-part label on the outside of every backup container:

1. Wallet designation — A name you already use (“Primary BTC Ledger”, “Altcoin Paper 2”)
2. Location code — Room and container (“Office safe, slot B”, “Garage lockbox, key 3”)
3. Last verified date — Month and year you confirmed the backup matches the active address

Never write address fragments, seed words, or PIN hints on external labels. Those belong inside the sealed container only.

Color bands for coin type

Some clients use colored tape on hardware wallet cases: gold for Bitcoin payout wallets, silver for altcoin destinations, red for retired devices still holding historical keys. The color scheme is personal; what matters is that it is written down in the archive index.

The drawer problem

Home miners often store backups in desk drawers mixed with unrelated documents. We assign drawer contents a single archive page listing every item in that drawer, cross-referenced to wallet designations. When you add a new backup to a drawer, update the page before closing it.

What to do after a rotation

When you change a payout address, update the label last-verified date even if the physical backup did not move. Stale dates are a reliable signal that something may have changed since the last catalog session.
