Share only the information needed to complete and evidence the sale. A genuine buyer may need model, condition and a privately supplied identifier; they do not need unrestricted access to your account, identity documents or one-time security codes.
Protect device identifiers
Keep the full IMEI and serial number out of public listing photographs. Provide them privately where a serious buyer needs to run a check, and retain your own dated record before postage or collection. Redact unrelated personal details from receipts.
Protect payment and account access
- Open the banking or marketplace app independently rather than using a link in a message.
- Never disclose a password, one-time code or account-recovery answer.
- Do not install “payment verification” or remote-control software.
- Check the recipient and amount before sending money.
- Keep communication inside the platform where protection depends on it.
Use photographs carefully
| Useful evidence | Information to hide |
|---|---|
| Overall condition and disclosed damage | Full IMEI, serial, home address and notifications |
| Device settings showing model and storage | Apple Account, Google Account and phone number |
| Packing process | Shipping labels before public posting |
| Receipt showing date and seller | Payment card, order account and unrelated purchases |
For in-person testing
Use a temporary test SIM where appropriate and supervise the phone. Do not allow a stranger to browse private messages, photographs or saved passwords under the pretext of testing. Complete backups and sensitive account removal before the meeting, then erase only after the buyer has inspected the functions that need to be visible.
After the transaction
Remove the device from any remaining trusted-device, insurance or management lists where appropriate, but retain necessary sale evidence. Delete buyer or seller personal data when it is no longer needed for a legitimate dispute, warranty or record purpose.
