IMO numbers are issued in broadly chronological blocks. Within 500 either side of 9682875 this registry holds 62 other vessels, whose median build year is 2014 and which range from 2011 to 2017. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 2016.

Its IMO number, 9682875, carries its own check digit. The first six digits are weighted seven down to two and summed — 9×7 + 6×6 + 8×5 + 2×4 + 8×3 + 7×2 = 185 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
