Area Code 45 – Kisvarda

Overview of Area Code 45 (Kisvárda, Hungary)

Area code 45 is a geographic National Destination Code (NDC) assigned to the Kisvárda telephone exchange area within the Hungarian numbering plan, as defined under ITU-T E.164. It serves the town of Kisvárda and its surrounding administrative district in Szabolcs-Szatmár-Bereg County, located in the Northern Great Plain region of northeastern Hungary. The coverage area includes Kisvárda itself, along with nearby settlements such as Ajak, Anarcs, Döge, Fényeslitke, Gyulaháza, Pap, and Újkenéz. This code is used exclusively for fixed-line (PSTN) services, including traditional analog lines, ISDN, and fixed VoIP services that are registered to a physical address within the exchange area.

Dialing Formats and Procedures

When calling a subscriber within the Kisvárda area, the number format is 45 XX XX XX (eight digits total, including the area code). For local calls within the same exchange area, callers may dial the subscriber number without the area code, depending on the operator's dialing plan. However, for all calls from outside the area code, including mobile and VoIP, the full national number must be used: 45 XX XX XX. International callers must dial the Hungarian country code +36, followed by the area code without the leading zero, and then the subscriber number: +36 45 XX XX XX. For example, a local number 45 123 456 would be dialed as +36 45 123 456 from abroad. It is important to note that Hungary uses closed dialing plan, so the leading '0' is only used for domestic calls, not for international calls.

Geographic and Administrative Context

Kisvárda is a significant economic and cultural hub in the region, with a population of approximately 16,000. The area code 45 is one of several geographic codes in Hungary, each corresponding to a specific primary exchange area. The assignment is managed by the National Media and Infocommunications Authority (NMHH). As of the latest numbering plan updates, no overlay code has been introduced for this area, meaning that the 45 code is the sole geographic code for the region. Subscribers in this area may have the option to switch to VoIP services, but if they retain a geographic number, it will still be associated with the Kisvárda exchange.

Caller Instructions

• Local callers (within the 45 area): dial the 6-digit subscriber number directly (e.g., 123 456).
• National callers (from other Hungarian areas): dial 45 followed by the subscriber number (e.g., 45 123 456).
• International callers: dial the international access prefix (e.g., 00 or +), then 36, then 45, then the subscriber number (e.g., +36 45 123 456).

This code is not used for mobile services; mobile numbers in Hungary begin with 20, 30, 31, 50, 70, etc., and are non-geographic. For any assistance, contact your service provider for specific dialing instructions.
