IMO numbers are issued in broadly chronological blocks. Within 500 either side of 7048221 this registry holds 31 other vessels, whose median build year is 1969 and which range from 1946 to 1972. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1971.

Its IMO number, 7048221, carries its own check digit. The first six digits are weighted seven down to two and summed — 7×7 + 0×6 = 111 — and the last digit of that total, 1, must equal the seventh digit, 1. It does, so this number is well formed.
