2139847 is the station's full identifier. It factors as 199 × 10753, and both factors are prime.
2139847 falls below the cardinality of a PubMed record, a Canadian patent application, a European patent application. Those systems assign identifiers sequentially, so it necessarily holds one in each. This is a property of the registries, not of the number. The cardinalities are published here.
