According to the ITU E.164 country-code list and Romania's national numbering plan published by ANCOM, +40 is the country calling code for Romania. Romanian phone numbers use a 9-digit national significant number, while domestic dialing commonly includes the national prefix 0. Enter the full number in Fonable's live checker to confirm a callable rate before you call.

Romania's official numbering plan uses the +40 country calling code followed by the 9-digit national significant number. Domestic numbers are often written with the national prefix 0, so a Bucharest landline 021 becomes +40 21 internationally and a mobile number beginning 07 becomes +40 7 internationally.

The leading 0 is Romania's national prefix for domestic dialing. Remove it before adding +40: a local Bucharest landline written as 021 234 5678 becomes +40 21 234 5678, and a local mobile written as 0721 234 567 becomes +40 721 234 567. The remaining 9 digits stay the same.
The exact Fonable price depends on the full Romanian number, not only the +40 country calling code. Use the live number checker on this page to see whether Fonable can confirm a callable rate and the current per-minute price for that specific number.
Romania uses the Europe/Bucharest time zone, with Eastern European Time in winter and Eastern European Summer Time in summer. In Romania's numbering plan, common geographic codes include 21 for Bucharest, 264 for Cluj-Napoca, 232 for Iasi, and 241 for Constanta. The table also shows the current local time.

For business calls, check the recipient's published office hours before you dial. Romania changes between EET and EEST, so the local time difference can shift during daylight saving transitions.
This guide uses the ITU E.164 country-code list for +40, Romania's national numbering plan, and ANCOM's E.164 numbering presentation for examples of domestic and international formatting. Static examples explain number format; they do not promise that Fonable can call a particular number.
For an exact Fonable price, use the live number checker. Its result is the authority for whether Fonable can confirm a callable rate for the full number. For callback safety, remember that a displayed +40 number can be spoofed and verify unknown callers through a separately trusted source.

+40 is the country calling code for Romania. The ITU assigns 40 to Romania in the E.164 country-code list. When you enter a Romanian number in Fonable, use +40 followed by the Romanian national significant number and remove the domestic prefix 0 from locally written numbers.
Romanian phone numbers use a 9-digit national significant number. Domestic dialing often adds the national prefix 0 in front, which is why locally written landlines and mobile numbers often appear as 10 digits. In international format, drop 0 and use +40 plus the same 9 digits.
No. The leading 0 is Romania's national prefix for domestic dialing. Remove it before adding the +40 country calling code. A locally written mobile starting 07 becomes +40 7, and a Bucharest landline starting 021 becomes +40 21 in international format.
Enter the number in international format: +40 followed by the 9-digit Romanian national number without the domestic prefix 0. A mobile written locally as 0721 234 567 becomes +40 721 234 567. Use the live number checker to confirm the exact callable rate before you sign in to call.
Enter the number in international format: +40 followed by the 9-digit Romanian national number without the domestic prefix 0. A Bucharest landline written locally as 021 234 5678 becomes +40 21 234 5678. The same rule applies to other geographic codes such as 264 for Cluj-Napoca or 241 for Constanta.
Bucharest commonly uses the geographic code 21 in Romania's numbering plan. In international format, a Bucharest landline begins +40 21, followed by the remaining subscriber digits. ANCOM also documents other Romanian geographic codes such as 264 for Cluj-Napoca, 232 for Iasi, and 256 for Timisoara.
Yes. Romanian mobile numbers are commonly written domestically with 07, and in international format they appear as +40 7 followed by the remaining digits. The domestic prefix 0 is removed when you convert the number to international format, so 07 becomes +40 7 rather than staying 07.
Yes. Romania uses Europe/Bucharest, which changes between Eastern European Time and Eastern European Summer Time. That means the time difference can shift during daylight saving transitions. If your call is time-sensitive, check the current Romania time on the page instead of assuming the offset is fixed all year.
Yes. 0040 and +40 both lead into Romania when the calling service supports 00 as the international access prefix. The 00 is not part of the Romanian country calling code itself. In Fonable, enter the number with +40, not with the 00 prefix.
Yes. Fonable is a browser-native calling service. Enter the full Romania number in international format, use the live checker to confirm a callable rate, and sign in only when you are ready to place the outbound call. Checking the number itself does not require a login.
The most useful reference cities are Bucharest, Cluj-Napoca, Timisoara, Iasi, Constanta, Brasov, Craiova, Galati, Oradea, and Sibiu. Those cities cover several of the geographic prefixes users search for when they want to verify whether a Romanian landline format looks correct before dialing it internationally.
Check whether you recognize the caller and whether the full number matches a contact or an official website. A familiar Romanian prefix does not prove the caller's identity because caller ID can be spoofed. When in doubt, use a separately verified number instead of returning the missed call directly.
Check a specific number's live callable rate, look up another country calling code, or open the browser dialer after you have confirmed the number.
A +40 caller ID does not prove that the call came from Romania because caller ID can be spoofed. If you do not recognize the caller, verify the person or organization through a trusted channel and use a separately sourced number instead of relying only on the missed-call display.
Enter a Romanian number such as +40 721 234 567 in the live number checker. Checking requires no login. If Fonable confirms a callable rate, sign in to place the outbound international call from your browser.
