IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7028415 this registry holds 37 other vessels, whose median build year is 1970 and which range from 1922 to 1971. That places this hull’s registration in the same part of the series; no build year is recorded for this vessel itself.

Its IMO number, 7028415, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 0×6 + 2×5 + 8×4 + 4×3 + 1×2 = 105 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
