Most new landline companies, like UPC Romania (formerly Astral) or Romania Data Systems (RDS), were granted new area codes with Z =3, e.g. 031-xxx-xxxx for Bucharest, and 03pp-xxx-xxx for the rest of the country. Because these area codes are shared between more companies, the entire number must be dialed, even within the same network.The numbers with Z =2, e.g. 021-xxx-xxxx or 02pp-xxx-xxx , belong almost exclusively to 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. Formerly within Romtelecom, local numbers were always dialed without area codes, but other numbers were always to be dialed with the area codes, even if it was the same one. Hovever this was changed beginning with 3 May 2008: from that date Romtelecom subscribers can dial full 10 digit numbers for local calls, and since 1 August 2008 they are required to dial the full 10 digit number. The mobile companies use area codes starting with 7: 71 for Romtelecom, 72 and 73 for Vodafone Romania (previously branded as Connex), 74 and 75 for Orange Romania (previously branded as Dialog), 76 for Cosmote Romania (previously branded as Cosmorom), 77 for RCS&RDS, 78 for Zapp Mobile, etc. Free phone numbers start with 800 (like 0-800-xxx-xxx ). Strangely, some companies to whom a numbering class is allocated may not grant toll-free access to those numbers for other networks. Therefore, sometimes a "toll-free" number is advertised as "toll free only within some operator". Some 08pp codes are used for various services, like:
