The following information is displayed on the 2D barcode of the inner box label.
- Part number (1P)
- Total quantity (Q)
- Trace code (1T)
- Trace code quantity (14Q–15Q)
- Build code (2P)
- Wafer lot number (30T)
- Seal date (9D)
- Box ID (3S)
- nILN (31T)
The wafer lot number (30T) is the foundry's lot number used for traceability. nILN (31T) is Nordic Semiconductor's lot number used for inventory tracking. Both numbers are available only in the 2D barcode.
