Use the SCAC lookup when you need to identify the ocean carrier associated with a known code. Container prefixes identify the equipment owner or principal operator, which may differ from the carrier moving the box. Bill of lading and booking lookups match a known leading SCAC first, then use SCACbot for a clearly labeled probability-based prediction when no prefix matches.
Use the check-digit calculator for a different job: checking whether an ISO 6346 container number is mathematically consistent before entering it into another system.
