IMO Ship Number Validator API — Check Digit Verification

The IMO Ship Number Validator API validates IMO ship identification numbers using the official 7-digit check-digit algorithm (weights 7 down to 2, modulo 10). It verifies vessel IMO numbers instantly and returns clean JSON, with no login required.

What the IMO validator checks

Format — a 7-digit number, optionally prefixed with "IMO".
Check digit — the last digit computed from the first six via the official weighted sum.

API usage

GET /validate?imo_number=9074729

The response returns validity, the normalized number, and the expected vs. given check digit.

Use cases

Validate vessel IMO numbers in maritime, port, insurance and logistics systems, and clean ship-registry data before import.

Pricing

Pay-per-event: $0.001 per API call.

Notes

This Actor performs offline check-digit validation only; it does not look the vessel up in any live registry.
