IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9976707 this registry holds 7 other vessels, whose median build year is 2024 and which range from 2024 to 2025. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2025.

Its IMO number, 9976707, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 9×6 + 7×5 + 6×4 + 7×3 + 0×2 = 197 — and the last digit of that total, 7, must equal the seventh digit, 7. It does, so this number is well formed.
