Romania numbers sit under country code +40 in an open plan. Each one has a 2-digit area or mobile prefix and a 7-digit subscriber line. That is 9 digits in all. A domestic "0" usually comes before the prefix. Drop it when you dial Romania from abroad.
Carriers & language
3 major networks cover Romania: Orange Romania, Vodafone Romania, Digi Mobil. Internet penetration is 87%. VoIP is permitted and regulated by ANCOM (National Regulatory Authority for Communications). Romanian is the main language and RON is the currency. Use both when you write IVR scripts, SMS content and support hours.
Europe context
Most European numbering plans follow ITU-T E.164. They use a national trunk prefix that is dropped for international dialing. Cross-border VoIP is widely supported across the region.
Skipping the exit code
Reaching Romania from the US requires the 011 exit code ahead of +40 — skip it and the call won't connect.
Keeping the national trunk "0"
If a Romania number is written with a leading 0 for domestic use, omit that 0 after the +40 country code when calling from abroad.
Ignoring the time difference
UTC+2 governs local business hours in Romania; confirm the time there before placing the call.
