# Global Shipment Identification Number (GSIN) (`gsin`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

GS1 identification key that a seller (shipper) gives to a shipment: the logistic units that it sends together to one buyer. Seventeen digits: a GS1 Company Prefix, a shipper reference and a GS1 check digit. In barcodes it is carried by Application Identifier (402); the element string is the pattern gs1_ai_402.

- Personal data (PII): no
- Categories: GS1 standards (gs1), Shipping and delivery (shipping), Transportation (transport)
- Countries: global
- Languages: Common to most languages (common)
- Classification: identifier
- Patterns: `gs1_ai_402`

## Detection

Regular expression (Python `re`):

```
^\d{17}$
```

Check digit algorithm: `gs1_mod10`

## Examples

- `95287650000042178` — Synthetic value with the GS1 demonstration prefix 952 and a valid check digit
- `95287651000275160` — Synthetic value with the GS1 demonstration prefix 952 and a valid check digit
- `95287650000042179` (invalid example) — Last digit changed: fails the GS1 check digit
