Why a Hardware Wallet Serial Number Belongs in Your Inheritance File
Device identification helps heirs distinguish between multiple wallets and verify they have the correct physical unit before engaging recovery specialists.
When heirs inherit cold storage, the first object they encounter is usually a small plastic or metal device with no obvious label. A Ledger Nano S looks identical to every other Ledger Nano S. Without documentation, an heir cannot confirm whether the device in the desk drawer is the one holding Bitcoin or an empty spare purchased as a backup.
What to Record
For each hardware wallet in your possession, note:
- Manufacturer and model (e.g., Ledger Nano X, Trezor Model T, Coldcard Mk4)
- Serial number, printed on the device or packaging
- Firmware version at last update
- Date of purchase and original vendor
- Associated blockchain networks and approximate allocation
This information does not expose your funds. It orients heirs and recovery professionals before any seed material is handled.
Where Heirs Look First
In our experience, heirs search in this order: home office drawers, safe deposit boxes, attorney files, and email archives. A single indexed document that lists device locations eliminates weeks of searching through unrelated storage.
A Common Oversight
Many holders maintain a “decoy” or empty wallet for travel. Without serial numbers in the record, heirs may spend effort on the wrong device. Listing each unit by serial number prevents this confusion.
If your inheritance record is more than two years old, schedule an annual review to add devices acquired since the last filing.
