Police register: what a repairer must record when buying back
Buying used devices requires keeping a register. What it contains, and how to keep it without paper.
In France, a business that buys used goods to resell them must keep a register (article 321-7 of the French criminal code), often called the « livre de police ». It identifies each item bought and the person who sold it.
What it contains for a phone
- The buyback date and its sequence number.
- The description of the device, with its IMEI or serial number.
- The seller’s identity and ID document reference.
- The price paid.
In Fixara, each buyback is recorded with the seller’s on-screen signature, and no entry can be deleted: see buybacks and the police register.
To check
The exact entries and retention period depend on your activity: ask your prefecture or your advisor.
