Area Code 2539 – Alaverdi/Odzun/Tsaghkashat/Tumanyan, Lori

Geographic Coverage and Administrative Jurisdiction

The +374 2539 prefix is a geographic National Destination Code (NDC) assigned to the Alaverdi, Odzun, Tsaghkashat, and Tumanyan areas within the Lori Province of Armenia. This code is part of Armenia's public switched telephone network (PSTN) and is allocated to fixed-line services in these northern communities, which lie near the Debed River valley. The administrative jurisdiction falls under the Lori regional administration, with Alaverdi serving as the primary urban center, while Odzun, Tsaghkashat, and Tumanyan are smaller settlements within the same calling area.

Dialing Formats and Caller Instructions

For callers within Armenia, the national format requires dialing 0 2539 XXX XX (where X represents the local subscriber number). The leading '0' is the national trunk prefix, and '2539' is the NDC. For international callers, the format is +374 2539 XXX XX or 011 374 2539 XXX XX (from North America). The local subscriber number length is six digits, making the complete national significant number (NSN) eight digits (excluding the trunk prefix).

When calling from a mobile phone within Armenia, the same national format applies. If you are physically in the Alaverdi area and calling another local number, you may be able to dial just the six-digit subscriber number, depending on your operator's settings, but using the full national format is always safe.

Overlay Considerations and Numbering Plan

Armenia's numbering plan does not currently apply overlay codes for this region; the 2539 prefix is unique to the Alaverdi/Odzun/Tsaghkashat/Tumanyan area. However, as part of the broader E.164 plan, all geographic numbers in Armenia are fixed at eight digits after the country code. There is no per-call charge for dialing a geographic number within Armenia beyond the standard call rates, which vary by operator and subscription plan.

Service and Usage Notes

This prefix is exclusively for fixed-line services, including residential and business lines. It is not used for mobile or VoIP services, which have their own non-geographic prefixes (e.g., 77, 91, 93, 94, 98, 99 for mobile). If you receive a call from +374 2539, it originates from a landline in the Lori region. For emergency services, always dial 101 (fire), 102 (police), or 103 (ambulance) regardless of the prefix.
