Romania numbering plan & how to dial
Under country code +40, Romania numbers follow an open plan built from a 2-digit area or mobile prefix and a 7-digit subscriber line — 9 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Romania internationally.
3 major networks cover Romania (Orange Romania, Vodafone Romania, Digi Mobil), against 87% internet penetration. VoIP is permitted and regulated by ANCOM (National Regulatory Authority for Communications). Because Romanian is the primary language and RON the local currency, both should inform IVR scripts, SMS content, and support hours.
Most European numbering plans follow ITU-T E.164 with a national trunk prefix that is dropped for international dialing, and 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.
Permitted — ANCOM regulated
Regulated by ANCOM (National Regulatory Authority for Communications)
- VoIP providers must register with ANCOM under the Law no. 159/2016 on Electronic Communications.
- Emergency service access (112) is mandatory for all VoIP operators serving Romanian subscribers.
- Lawful interception obligations apply to all licensed Romanian VoIP operators under security law.

FAQ
Calling Romania — frequently asked questions
Romanian is the primary language in Romania — IVR prompts, SMS copy, and support scripts should be written in it for the best response rates. Getting the greeting and menu options right in the local language is often the difference between a caller staying on the line or hanging up.
Romania's ISO 3166-1 alpha-2 code is RO, distinct from its dialing code (+40). The ISO code is used in things like domain names and shipping forms, while the dialing code is what actually routes a phone call.
Calls from the US to Romania start at $0.010/min on Twiching, billed per second on Tier-1 routes. That's the same rate whether the call lands on a mobile or fixed-line number in the country.
3 major networks serve Romania: Orange Romania, Vodafone Romania, Digi Mobil. Twiching interconnects directly with these carriers over Tier-1 routes rather than relying on third-party transit.
Yes — Twiching interconnects directly with Orange Romania and other major Romania networks over Tier-1 routes for consistent call delivery. That direct interconnect is what keeps answer-seizure ratios high compared to routing through third-party wholesale transit.
Yes. VoIP is permitted in Romania, regulated by ANCOM (National Regulatory Authority for Communications), so businesses can run cloud numbers and SIP termination on compliant routes. There's no special licensing hurdle for a Twiching customer to clear before calling or texting into Romania.
