Some recent companies appear to be missing from all databases at UKCH. For example, company number 10002943 does not exist, even in WebCheck. Based on the two numbers above and below it, it would have been incorporated on 12-Feb-2016. Across the numeric range, I have made the following count of missing companies:
7000000-7999999: 2178
8000000-8999999: 3803
9000000-9999999: 562
10000000-10699999: 630
Did these companies ever exist, and if so, what has happened to them?
