Serial numbers
A serial number can be registered only once in your store. If a customer enters a serial that is already registered, they see the same "couldn't verify" message as for a wrong code; check it in Registrations if they contact you.
Formats
Must match a format checks the shape of the serial number:
| Character | Means |
|---|---|
# | a digit |
A | a letter |
| anything else | itself |
TJ-##### accepts TJ-00421 and tj-00421, but not TJ-421.
Imported lists
Must be on my imported list accepts only serials you imported under Settings → Serial numbers:
- Upload a CSV or text file, or paste the serials, one per line.
- Optionally add the SKU after a comma:
TJ-00001,TJ-BAG-01. With a SKU, a customer who bought the product elsewhere can register the serial without choosing the product. - A header row is skipped. Import shows how many serials were added, how many were already on the list or repeated, and which lines couldn't be read. Up to 10,000 lines per import.
- Imports lists each import; you can undo one.
- Look up a serial number shows whether a serial is on the list and whether it's registered.
Voided registrations
When you void a registration, its serial number can be registered again. See Claims and registrations.
