Klaus, Rick, Richard,
Maybe NRAs don't have detailed numbering data, for the purposes of daily admin.
But at least they will have administrative or strategic visibility and statistics on national porting activities and know who donors and recipients of numbers are, exactly.
In the EU 25 countries the European New Electronic Communications Regulatory Framework directive and Universal Service directives mandate the NRA ownership of national numbering resources along with the national administrations.
Provisions are in built to the USO directive recitals 40 to 42 and Article 30 is where you can find the suite of porting reference data.
Note the consumer aspects and pro competitive aspects of same.
From a PSTN point of view, both databases and onward routing can unilaterally or co-exist. These decisions are historically entrenched in administration matters including numbering policy and costs of implementation at a national, fixed line and mobile/GSM level.
For ENUM and its origins at the beginning, my understanding is that if was derived in order to assist with Number and address portability in the Swedish market.
This discussion might assist in a numbering administration and spectrum tidy up. E.g. ENUM early days.
I can send these directives out for your perusal if you like.

In most CEPT countries MNP is implemented using centralised NP
databases. These are typically managed by a consortia of network
operators, so NRAs may not have any information about ported numbers.
Well, I think that this fact is not very important.
At least also Malta and Cyprus has distributed MNP databases, but does
this mean that the validation information is not available or is it
possible to gather the required data from multiple databases maintained
by different operators?

Austria uses onward routing for fixed line NP. There is no centralized
DB which shows which number has been ported to whom.
The NRA only keeps tabs on what number have been ported, but this DB
does not include the information necessary to route calls.
