Area Code 3656 – Isfana, Naryn region

Geographic Overview

The area code 3656 is a geographic National Destination Code (NDC) assigned to the town of Isfana and its surrounding administrative area within the Naryn region of the Kyrgyz Republic. Although Isfana is geographically located in the western part of the country, near the Tajikistan border, the code 3656 is officially allocated under the Naryn regional numbering plan, reflecting the administrative jurisdiction of the Kyrgyz national telecommunications regulator. This code is used for fixed-line (PSTN) services, and it routes calls to subscriber lines within the Isfana exchange area.

Dialing Formats

For callers within Kyrgyzstan, the national trunk prefix is 0, followed by the area code and the subscriber number. The local subscriber number length in the 3656 area is typically 6 digits, making the complete national dialing sequence 0 3656 XXX XXX (11 digits total). For example, a local number might be 0 3656 12 34 56.

For international callers, the Kyrgyzstan country code is +996, and the leading trunk prefix is omitted. Therefore, the international dialing format becomes +996 3656 XXX XXX. For instance, to call a subscriber with the national number 0 3656 12 34 56, an international caller would dial +996 3656 12 34 56.

Caller Instructions

Local callers within Isfana may be able to dial the 6-digit subscriber number directly without the area code, depending on the local exchange configuration. However, for clarity and to avoid routing errors, it is recommended to always use the full national format, especially when calling from mobile networks.

Callers from other regions of Kyrgyzstan must dial the trunk prefix 0 followed by 3656 and the subscriber number. For example, from Bishkek, one would dial 0 3656 12 34 56.

International callers should replace the trunk prefix with the country code +996 and drop the leading zero. Thus, the correct international format is +996 3656 12 34 56.

Numbering Plan Considerations

As of the latest ITU-T E.164 national numbering plan, there are no overlay codes for the 3656 area. The code is exclusively geographic and is not used for mobile or non-geographic services. Mobile numbers in Kyrgyzstan are identified by distinct prefixes (e.g., 5xx, 7xx) and are not tied to geographic regions. Fixed-line numbers under 3656 are assigned to the incumbent operator, Kyrgyz Telecom, and are not portable to other fixed-line operators within the same geographic area. For VoIP or international calling services, users should ensure that their service provider supports termination to geographic numbers in Kyrgyzstan, as some providers may have restrictions on certain destinations.
