NZBN Anatomy & Structure
The NZBN is a 13-digit GS1 identifier used across New Zealand commerce:
| Position | Field | Length | Meaning & Specification | Example |
|---|---|---|---|---|
| 1 to 5 | GS1 Government Prefix | 5 digits | New Zealand government prefix (94290) | 94290 |
| 6 to 12 | Entity Identifier | 7 digits | Company identification number | 3102458 |
| 13 | Check Digit | 1 digit | GS1 Modulo 10 check digit | 7 |
Validation Algorithm (GS1 Modulo 10)
Mathematical checksum validation based on GS1 standards:
Weighted sum of first 12 digits using alternating weights [1, 3].
- 1. Extract the first 12 digits and multiply by alternating weights 1 and 3.
- 2. Sum the products and compute modulo 10.
- 3. Confirm that the calculated check digit equals the 13th digit.
