Area Code 358 – Bolnisi

Geographic Overview

The +995 358 area code is a geographic National Destination Code (NDC) assigned to the Bolnisi region in the Republic of Georgia. Bolnisi is a historic town located in the Kvemo Kartli province, approximately 60 kilometers southwest of the capital, Tbilisi. The region is known for its cultural heritage, including the 5th-century Bolnisi Sioni basilica, and serves as an administrative and economic center for surrounding villages. The numbering area covers the town itself and nearby settlements, with fixed-line telephone services provided by local operators under the oversight of the Georgian National Communications Commission (GNCC).

Dialing Formats

To call a fixed-line number in Bolnisi from within Georgia, subscribers must dial the trunk prefix 0, followed by the area code 358 and the subscriber's 5-digit local number. The complete national format is 0 358 XX XX X. For example, a local number such as 12 345 would be dialed as 0 358 12 345 from any other part of Georgia. When calling from abroad, the international access code (typically 00 or +) is used, followed by Georgia's country code 995, the area code 358 without the leading zero, and the 5-digit subscriber number. Thus, the international format is +995 358 12 345.

Caller Instructions

• Local callers within Bolnisi: In most cases, local calls may be made using the 5-digit subscriber number alone, but to ensure proper routing, it is recommended to use the full national format 0 358 XX XX X.
• Callers from other Georgian cities: Dial 0 358 followed by the subscriber number. Do not omit the leading 0.
• International callers: Dial your country's exit code (e.g., 011 from North America), then 995 358 and the subscriber number. Do not include the leading 0 of the area code.

Numbering Plan Considerations

The Georgian numbering plan follows ITU-T E.164 recommendations. Geographic area codes are assigned based on administrative regions, and the length of subscriber numbers within an area code is fixed. As of the current plan, no overlay codes have been introduced for Bolnisi, meaning the 358 code is exclusively used for fixed-line services in this region. Mobile numbers in Georgia are identified by their own non-geographic prefixes (e.g., 5xx, 7xx) and are not affected by this area code. When dialing from abroad, it is essential to replace the leading zero of the national prefix with the +995 country code to ensure proper international routing.
