Questions about +40
Which country is +40?
+40, or country code 40, belongs to Romania. Numbers there follow the code with an area code, such as 021 for Bucharest, or a mobile prefix such as 07.
What is +40?
+40 is the part you dial before a Romanian number when you call from another country. It replaces the 0 at the start, so 0712 034 567 becomes +40 712 034 567.
What is the difference between +40 and 0040?
The + stands for your exit code. Romania's own exit code is 00, so 0040 and +40 reach the same number. From the US or Canada, dial 011 40 instead.
Do I drop the 0 after +40?
Yes. The 0 is Romania's trunk prefix and works only inside the country. Dial +40 211234567, not +40 0211234567.
Can I text a +40 number?
Yes. Write the number as +40 without its first 0, and your carrier sends the text abroad at its international rate.

ANCOM assigns the whole 60 to 69 range to mobile networks, together with 70 to 79, so a number starting with 06 is a real Romanian mobile, not a mistake.
