In theory there are about 45M unique LSIDs in UniProt (27M of which 
represent non-UniProt resources). But note that few of these resources 
follow the rules (such as not changing), and none of these identifiers can 
at the moment be resolved with the official mechanism.

The number would increase substantially if you also counted obsolete 
versions (though only few databases have version numbers and support 
retrieval of obsolete versions).
