Hi
Andy That may work for US but what about the world-wide collector?
The Blanco Specialized Venezuela Catalog has Blanco, Yvert & Tellier and Scott catalog numbers.
I am sure collectors have spreadsheets, documents, etc. that are "cross references" to two or more catalogs. I know that Scott does not allow lists to be posted due to copyright laws and I am sure the other publishers are the same. Maybe the catalog publishers relax a little and allow these lists to be put on the internet, as long as one is not creating a catalog to be published.

So, by the logic I applied above, if Blanco is the numbering system that is most popular for Venezuela, Scott would use those numbers in their World Catalog, and if Blanco had a worldwide catalog, they would use Scott numbers in their US section. If all the catalog printers agreed to specialize and cross-license, we could then actually have a universal numbering system.
