Calling Romania from United Kingdom: what to know

Romania answers on the country code +40, with the capital in Bucharest and most business concentrated around Bucharest, Cluj-Napoca and Timișoara. The working language for business is Romanian, and local offices generally keep hours of 9:00 to 18:00.

From United Kingdom the outbound access code is 00, so a manual dial reads 00 then +40 then the local number. StartACall removes that step: the call goes through your browser, so there is nothing to install and no SIM card to swap when you travel between United Kingdom and Romania.

Most mobiles in Romania sit on operators such as Orange Romania, Vodafone Romania, Digi Mobil (RCS&RDS). Romanian numbers are 9 digits after +40; drop the leading 0 from the trunk format (Bucharest landline '021 xxx xxxx' → '+40 21 xxx xxxx').

Romania runs on UTC plus 2, and it shifts for daylight saving, so confirm the current difference before an early or late call.
