The numbers with Z=2, e.g. "021-xxx-xxxx" or "02pp-xxx-xxx", belong almost exclusively to Telekom Romania (formerly called Romtelecom). However, smaller companies were granted numbers with these area codes, like "021-59x-xxxx", and the local numbers are assigned in descending order of the first 3 digits, like (599xxxx, 598xxxx, ..., or 529xxxx, 528xxxx, ...). In Bucharest, local numbers starting with "5" were not used by Romtelecom, hence the usage of this digit. For other counties, if "5" had not been used by Romtelecom, it is preferred for the first digit of numbers of other companies. There are few companies requesting numbering resources with Z=2, and in most cases the companies provide local service only and do not extend their network in the whole country.
