Thanks for working on this proposal.

Introduce a new reg-nr: attribute for RIPE NCC co-maintained organisation objects, containing verified company registration numbers issued by national authorities. Will this have some kind of scope to a country/registry? If I see a number, how do I know where to look it up? It might even be ambiguous without scope, as the same number might be used in different company registries. I don't know if all countries have a single registry. For countries with multiple regional company registries, such as Germany or the USA, we would specify which registry contains the legal entity’s record. For countries with a single national registry, the existing attribute with country code of legal registration together with the new company registration number attribute should be sufficient to identify the resource holder.
This sounds like a good thing to have.
Can we get that in WHOIS and then also have that as a dump for easy ingestion?
An example WHOIS entry on how this could look like could be a good example.
Here is an example for the RIPE NCC itself, adding a reg-nr: attribute : organisation: ORG-RIEN1-RIPE org-name: Reseaux IP Europeens Network Coordination Centre (RIPE NCC) country: NL org-type: LIR descr: RIPE NCC Operations address: P.O.
