It is part of the Lithuanian national numbering plan, which adheres to the ITU-T E.164 recommendation. The code is used for fixed-line (PSTN) services within the Biržai region, which includes the city of Biržai and its surrounding administrative areas.
Geographic Coverage and Administration

Dialing Formats
When calling a fixed-line number in Biržai, the national dialing format is 8 450 XXXXX, where '8' is the trunk prefix used within Lithuania, followed by the area code 450 and the subscriber number (typically 5 digits). For international callers, the format is +370 450 XXXXX (or 011 370 450 XXXXX from North America). For example, a local number might be +370 450 12345.
When dialing within the same area code, callers may omit the trunk prefix and area code, but this practice is becoming less common with the adoption of closed dialing plans. However, it is always safe to use the full national or international format.
Overlay and Numbering Considerations
As of the latest updates, there is no overlay code for the Biržai area. The 450 code remains the sole geographic code for the region. Subscriber numbers in this area are typically 5 digits long, resulting in a total national significant number length of 8 digits (excluding the trunk prefix '8').

- Local callers (within Biržai): Dial the subscriber number directly if using a fixed line within the same exchange, or use the full national format 8 450 XXXXX for calls from other Lithuanian regions.
- International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 370 (Lithuania's country code), followed by 450 and the subscriber number.
