IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5138656 this registry holds 6 other vessels, whose median build year is 1954 and which range from 1905 to 1961. 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, 5138656, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 1×6 + 3×5 + 8×4 + 6×3 + 5×2 = 116 — and the last digit of that total, 6, must equal the seventh digit, 6. It does, so this number is well formed.
