Overview of Romania's +40 775 Prefix
The +40 775 prefix is a non-geographic mobile number range assigned to Digi Mobil, the mobile virtual network operator (MVNO) arm of RCS & RDS, one of Romania's leading telecommunications groups. Unlike geographic area codes, 775 numbers are not tied to a specific city or region; they are used exclusively for mobile services, enabling subscribers to make and receive calls across Romania and internationally.
Technical Specifications and Numbering
In accordance with the ITU-T E.164 international numbering plan, a Romanian mobile number using the 775 prefix is structured as follows:
- Country Calling Code: +40
- National Destination Code (NDC): 775
- Subscriber Number: 6 digits (e.g., 123456)
- Full International Format: +40 775 123 456
- National Format (within Romania): 0775 123 456 (the leading zero is dropped when dialing internationally)
All Romanian mobile numbers, including those on the 775 prefix, have a total length of 10 digits in national format (including the leading zero) and 9 digits in international format (excluding the leading zero).
Dialing Instructions
Calling a 775 number from within Romania: Dial the full national number, including the leading zero: 0775 123 456. This applies to both landline and mobile callers.
Calling a 775 number from abroad: Dial the international access prefix of the originating country (typically 00 or +), followed by Romania's country code 40, then the NDC and subscriber number without the leading zero: +40 775 123 456.
Mobile Number Portability and Interoperability
Romania implemented Mobile Number Portability (MNP), allowing subscribers to retain their 775 numbers when switching to another mobile operator. Consequently, a number starting with 775 may not always be actively served by Digi Mobil; it could be ported to another network. Conversely, numbers from other operators may be ported to Digi Mobil. However, the prefix remains a reliable indicator of the original allocation.
Services and Usage
Digi Mobil offers a range of prepaid and postpaid plans using the 775 prefix, including voice, SMS, and high-speed data services (4G/5G). These numbers support standard mobile features such as international roaming, SMS, and MMS. For international SMS delivery, the number must be formatted in full international format: +40 775 123 456.
As a non-geographic prefix, 775 numbers are not tied to any physical location, making them suitable for individuals and businesses that require a mobile presence without regional constraints. They are widely used across Romania, from urban centers to rural areas, and are recognized as standard mobile numbers by all Romanian networks.
