Overview of Bulgarian Mobile Prefix 89
The prefix +359 89 is a non-geographic mobile network code assigned within Bulgaria's national numbering plan, as defined under ITU-T E.164. Unlike geographic area codes that correspond to specific cities or regions, the 89 prefix is used exclusively for mobile services, enabling subscribers to be reached anywhere in the country and abroad. Numbers bearing this prefix are typically 9 digits long after the country code, formatted as +359 89 XXX XXXX when dialed internationally, or 089 XXX XXXX for domestic calls.
Numbering and Allocation
The 89 prefix is allocated to multiple Mobile Network Operators (MNOs) and Mobile Virtual Network Operators (MVNOs) operating in Bulgaria. The leading '8' in the national significant number (NSN) indicates a mobile service, while the subsequent digits (in this case '9') further identify the specific operator or operator group. This structure allows for number portability, meaning that a subscriber may retain their 89 number even when switching providers. As a result, the prefix alone does not guarantee a particular network; verification of the current operator is possible through number portability databases.
Dialing Formats and Usage
- Domestic calls: Dial 089 XXX XXXX from any fixed or mobile line within Bulgaria. The leading '0' is the trunk prefix used for national dialing.
- International calls from abroad: Dial +359 89 XXX XXXX (or 00359 89 XXX XXXX using the international prefix from many countries). The leading '0' is omitted.
- International calls from Bulgaria: Dial 00 followed by the country code and the recipient's number, e.g., 00 44 89 XXX XXXX for a UK number.
Technical Considerations
Mobile numbers in Bulgaria are used for both voice and SMS services. For international SMS, the sender should use the international format +359 89 XXX XXXX. Calls to 89 numbers are routed via the home network of the subscriber, and when roaming, the call is connected through the visited network with applicable roaming charges. Number portability does not affect the dialing format; the caller always uses the same number regardless of the underlying network.
Regulatory and Cost Aspects
The allocation and management of the 89 prefix are overseen by the Communications Regulation Commission (CRC) of Bulgaria, in accordance with the national numbering plan. Tariffs for calls to 89 numbers vary depending on the caller's operator and subscription plan. Typically, calls to mobile numbers are charged at a higher rate than calls to fixed lines. For users calling from abroad, international rates apply, which are determined by the caller's home operator. It is always advisable to check with your service provider for specific charges.
