IMO numbers are issued in broadly chronological blocks. Within 500 either side of 8990902 this registry holds 25 other vessels, whose median build year is 1991 and which range from 1943 to 2004. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1996.

Its IMO number, 8990902, carries its own check digit. The first six digits are weighted seven down to two and summed — 8×7 + 9×6 + 9×5 + 0×4 + 9×3 + 0×2 = 182 — and the last digit of that total, 2, must equal the seventh digit, 2. It does, so this number is well formed.
