Shipping Container Number Check (ISO 6346 Format, Check Digit and Carrier)

omnial/shipping-container-number-check

Checks a shipping container number against the ISO 6346 standard: whether its format is valid and its check digit is correct, the owner code, equipment category letter and serial number it is made of, and the carrier the owner code belongs to when it is known. It does not return a container's location or movements.
