The standard Russian phone number format uses the country code +7, followed by a 10-digit national number. This russian phone number format is commonly written as +7 (AAA) XXX-XX-XX for landlines and +7 9XX XXX-XX-XX for mobile numbers.
What is the russian phone number format?
A Russian phone number consists of the country code +7 and a 10-digit national number. The first digit (2-9) indicates the type of service; landline numbers typically start with 3, 4, 8, or 9, while mobile numbers often start with 9. The first few digits after +7 indicate the type of service or geographic region, and the remaining digits form the subscriber number. For geographic numbers, the format is +7 (AAA) XXX-XX-XX, where AAA is a 3-4 digit area code. For mobile numbers, the format is +7 9XX XXX-XX-XX, where 9XX is the mobile prefix. The total length is always 10 digits after the country code.
International (+7) vs. domestic (8) format
The critical distinction when dialing a Russian number is whether you are calling from abroad or inside Russia. When dialing from outside Russia, you use the international format starting with +7. When communicating internationally or on digital platforms, include the country code +7 at the beginning to ensure accurate dialing. When dialing from inside Russia, you replace +7 with the trunk prefix 8. For example, the same Moscow landline would be dialed as +7 (495) 123-45-67 from abroad and 8 (495) 123-45-67 from within Russia. Similarly, a mobile number would be +7 916 123-45-67 internationally and 8 916 123-45-67 domestically.
Understanding Russian landline numbers
Russian landline numbers are geographic numbers that include an area code (also called a city code) that is usually 3 to 4 digits. Moscow uses two area codes: 495 and 499. After the area code, the remaining digits form the local subscriber number, which is often grouped in the format XXX-XX-XX. So a complete landline number written in international format looks like +7 (495) 123-45-67.
Understanding Russian mobile numbers
Russian mobile numbers have a consistent structure. After the country code +7, they begin with 9 followed by two more digits, forming the 9XX prefix. The three digits after the 9 in a mobile number form the mobile network code (MNC), which identifies the specific mobile carrier. The total length is 10 digits after +7. The standard format for a mobile number is +7 9XX XXX-XX-XX. For example, a mobile number might be written as +7 916 123-45-67.
