Telephone numbers in Bulgaria


Telephone numbers in Bulgaria are administered and regulated by the Communications Regulation Commission, which publishes information about the National Numbering Plan for telephone services. Internationally the country participates in the E.164 world numbering plan with telephone country code 359.
For all calls within the country, the full national number must be dialed for all calls. Dialing between area codes the national number is prefixed with trunk code of 0.

Dialing example

For example, to call a number in Sofia, dial:
  • 02 xxx xxxx from inside Bulgaria
  • +359 2 xxx xxxx from outside Bulgaria

    Fixed-line numbers

Domestic numbers are limited to eight digits in length. Area codes vary in length from one to five digits. Subscriber number lengths vary accordingly, from seven digits down to three digits. Sofia lines on digital switches have seven-digit numbers, those on analog switches had six; in Plovdiv, Varna and Ruse both are six digits; and in most other province capitals lines on digital switches have six-digit numbers and analog had five.
For a very long time, the state-owned Bulgarian Telecommunications Company had a monopoly on fixed telephone networks. However, this ended when a special law was adopted. BTC was privatized in 2004 and competing operators appeared.
Larger areas, such as Sofia, Plovdiv, Varna, and Burgas, are subdivided into zones. Although one cannot further reduce the number of dialed digits, the number itself shows which zone it is located in. For example, in Sofia, numbers starting with 2, 82, 92 are located in the Western suburbs, 7, 87, 97 in the Eastern suburbs, and 98 in the central area.
Around 2010, the intensive process of replacing the old analog switches with modern digital ones completed. In some areas it is even possible to guess if a subscriber number was changed from analog to digital during its existence or was subscribed as digital initially. For example, in Blagoevgrad a number starting with 88 was subscribed as digital, and a number starting with a single 8 was analog before.
The first digit also shows if a particular subscriber number is operated by BTC or another operator.
The area codes are always cited with the trunk code. When dialing, all subscriber numbers must be prefixed with trunk and area code except short codes. Numbers starting with 700, 800 and 90x as well as mobile ones are prefixed by '0' only. When dialing from abroad, the trunk code 0 is replaced with the country code 359.

Mobile numbers

Until 20 July 2003 GSM networks used six-digit subscriber numbers in accordance with the limit of eight digits for the domestic part of a number. With the increase of subscribers, all acquired new access codes. On 20 July 2003, Mobiltel used three codes 87, 88, and Globul used two 98 and . When these limits were also to be overwhelmed, seven-digit subscriber numbers and single access codes per operator were introduced, hence M-tel reverted to 088 only, while Globul took the old M-tel code 089 , and the rest were freed up. 799 to .
Dialing to a mobile network requires the access code together with the 0. Dialing from a mobile network requires either an area or access code with the trunk or international format. The latter becomes a normal practice, since most people use number lists of their handsets, more people use their phones in roaming and all four operators show the caller ID in international format.

Area codes

As in many countries, an area code is often written with the trunk code 0 prefixed.
