Area Code 320 – Lviv

Geographic Overview and Administrative Coverage

The +380 320 country-and-area code combination is the national destination code (NDC) for the city of Lviv and its surrounding administrative district within the Lviv Oblast of western Ukraine. As a geographic allocation under the national numbering plan, this code is tied to the PSTN (Public Switched Telephone Network) infrastructure of the region. Subscribers within this area are assigned numbers in the format +380 320 XX XX XX, where the NDC is followed by a seven-digit subscriber number. The code serves both residential and business lines, including fixed-line operators that have been authorized to provide services in this area, such as Ukrtelecom and alternative local carriers.

Dialing Procedures and Number Formats

For international callers, the complete E.164 format must be used: the international access prefix (e.g., 00 or +), followed by Ukraine's country code 380, the area code 320, and the seven-digit local number. For example, a call to a Lviv landline might be dialed as +380 320 123 4567 from abroad. Domestic callers within Ukraine must dial the trunk prefix 0, then the area code 320, and the subscriber number: 0 320 123 4567. When dialing from a phone within the same area code, the national format typically requires the full national number (including the trunk prefix and area code) because of the seven-digit numbering scheme and the possibility of number portability. No overlay codes have been introduced for this region, so the 320 code remains the sole geographic identifier for Lviv's fixed-line services.

Caller Instructions and Practical Considerations

Local callers should always include the trunk prefix and area code even for calls within Lviv, as this is mandatory for all fixed-line calls in Ukraine. For foreign callers, it is essential to replace the trunk prefix 0 with the country code 380 when dialing from abroad. The code is exclusively for fixed-line services; mobile numbers in Ukraine are allocated under separate non-geographic prefixes (e.g., 50, 63, 67, 95, etc.) and are not associated with the 320 area code. If you receive a call from +380 320, it originates from a landline in the Lviv region. However, due to number portability, a fixed number may be routed to a VoIP or mobile network, but the geographic significance of the prefix remains for billing and emergency services purposes.
