How this service works
Validates the ISO 6346 check digit and separates owner, category and serial components. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
Output
Returns a structured object indicating whether the ISO 6346 check digit is valid, and the parsed components: owner code (3-letter prefix), equipment category identifier, and 6-digit serial number. Fields that cannot be determined are returned as null and listed in an unavailable_fields array. Derived values include their calculation method; any source-backed values disclose source, time window, and data age.
Example use cases
Freight booking data quality check
“Before we book this shipment, validate the container number HLXU3456781 — I need to know if the check digit passes and what the owner code and category are.”
EDI message pre-processing validation
“I'm about to submit a customs declaration and need to confirm that container number TCKU7654321 is a valid ISO 6346 number with a correct check digit before I send it.”
Warehouse inbound receiving audit
“We just scanned container GESU4920154 at the gate — can you check if that container number is legitimate and break it down into its owner prefix, category, and serial components?”
Technical details
Endpoint
POSThttps://fracht.halowerk.com/v1/container-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically validate ISO 6346 shipping container numbers and parse their structured components (owner code, category, serial) in a logistics or freight automation workflow. It is purpose-built for container number validation specifically, unlike generic regex validators, and provides transparent disclosure of derived vs source-backed values along with null-safe field reporting via unavailable_fields.
Side effects
- Input container number not exactly 11 characters — schema enforces minLength/maxLength of 11
- Invalid characters in container number (must be alphanumeric per ISO 6346) — returns validation error
- Check digit fails — response indicates invalid with the expected vs actual check digit
- Network or payment failure via x402 protocol — 402 response if payment not settled
