🇷🇴 Romania Phone Number Format
Romanian phone numbers are 10 digits nationally. Mobiles start with 07 and are conventionally grouped 07XX XXX XXX — the spacing pattern that often prompts questions. The trunk 0 drops behind +40: 0712 345 678 becomes +40 712 345 678 internationally, or +40712345678 in strict E.164.

ANCOM, the 2007 Renumbering and the 07XX XXX XXX Convention
Romanian telecommunications is regulated by ANCOM (Autoritatea Națională pentru Administrare și Reglementare în Comunicații). The current 10-digit national plan took shape through a major renumbering in 2007, when all Romanian phone numbers were extended and standardised to reach 10 digits with the trunk 0 included — a change that eliminated older 6- and 7-digit subscriber formats and is the reason legacy databases sometimes contain shorter Romanian entries that no longer work.
Mobile operators are assigned specific ranges within the 07xx block: Orange Romania holds 072x and 073x, Vodafone Romania (now Digi Mobil following acquisition) occupies 074x and 075x, Telekom Romania Mobile covers 076x, and Digi Mobil also holds 077x. RCS&RDS / Digi added 078x as the fourth major entrant. The 07 prefix unambiguously identifies a mobile, making Romanian number type detection straightforward.
The conventional grouping for Romanian mobiles is 07XX XXX XXX — four digits, space, three digits, space, three digits. This specific spacing (rather than dashes or no spacing) is what users are searching for when they query "romanian phone number format spaces between digits." Landlines use Bucharest area code 021 and regional codes like 0232 (Iași), 0251 (Craiova), formatted as city-code + subscriber with a space between.
