Romania at a glance
The numbers and facts you need before you dial.
What is the country code for Romania?
Romania sits behind +40 — one of Europe's shorter country codes, fittingly easy for a nation whose people are scattered across the continent. Add it after your exit code when calling in from abroad. At home, every Romanian number wears a trunk 0 (021 for Bucharest, 07xx for mobiles); that 0 steps aside for +40 the instant the call crosses a border.
Code +40 was assigned to Romania by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Romania.
How to call Romania from anywhere
Three moves get you through: exit code, 40, then the national number minus its leading 0. Whether you're calling a Bucharest office or a relative who's relocated to Italy and kept their +40 line, the sequence holds.
Full example: +40 21(31) XXX XXXX — drop the local leading 0 when calling from abroad.
Romania phone number format explained
Domestically every Romanian number runs to 10 digits, trunk 0 included — drop that 0 and you have the +40 form. A neat quirk of the plan: the capital gets a short 2-digit code while the rest of the country uses 3.
Landline
0 + area code (2 digits for Bucharest, e.g. 21; 3 digits elsewhere, e.g. 264 for Cluj) + subscriber number. Example: 021 XXX XXXX → +40 21 XXX XXXX. Bucharest also carries 031.
携帯
07 + 8 digits. Example: 07XX XXX XXX → +40 7XX XXX XXX. Every Romanian mobile opens with 07.

Romania mobile network prefixes
The prefix after +40 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Orange Romania
Vodafone Romania
DIGI Mobil (RCS&RDS)
Telekom Romania Mobile
Romania time zone
Romania runs on Eastern European Time, UTC+2, and — unlike its EAT neighbours further south — it does spring forward, jumping to EEST (UTC+3) from late March to late October. Factor that DST swing into any recurring call schedule.
09:00–17:00 EET tracks the Romanian working day. A Bucharest morning meets the US East Coast late afternoon, so American teams calling the diaspora or partners are best off dialing before lunch their time.

Reading a 07x prefix as proof of carrier: with full portability live for years, a Romanian number can sit on Orange, Vodafone, Digi or Telekom regardless of how it starts
the most common assumption people get wrong.
Leaving the trunk 0 in place: don't dial +40 0 21…
the 0 disappears once +40 is on.

Tips to reduce the cost of calling Romania
Hand out a local +40 virtual/DID number so Romanian callers reach you at domestic rates.
Carry traffic over VoIP/SIP rather than carrier IDD tariffs.
Travelling in? A local eSIM (Orange, Vodafone or Digi) covers data plus on-net calling for a fraction of roaming.
Keep calls inside the EET working day to cut down on missed-call ping-pong.
