CNPAC - Czech Number Portability Administrative Center

The number portability nation-wide reference database (RNPDB) is a service that serves to all operators in the country as a sole valid source of information on ported numbers.

RNPDB presents an integrated database, to which all operators of public telecommunication networks can turn to in order to find out, whether a certain number was ported, to which operator this number was transferred and by which operator the number has been passed.
