Area Code 7149 – Kostanai

Geographic Overview

The +7 7149 dialing prefix is a geographic National Destination Code (NDC) assigned to the Kostanai (Kostanay) region of the Republic of Kazakhstan. While the +7 country code is historically shared with Russia, Kazakhstan has been progressively implementing its own country code (+7 7xx) and is transitioning to +997; however, as of the current numbering plan, +7 7149 remains the correct international dialing format for fixed-line subscribers in this area. The code serves the administrative center of Kostanai city and its surrounding districts, including the towns of Rudny, Lisakovsk, and Zhetikara, as well as numerous rural settlements within Kostanai Region.

Dialing Formats

For callers within Kazakhstan, the national trunk prefix is 8, followed by the area code and the subscriber number. The local number is typically six digits, making the complete national format: 8 7149 XX-XX-XX. For international callers, the format is +7 7149 XX-XX-XX (or 007 7149 XX-XX-XX from certain countries). It is essential to drop the leading 8 when dialing from abroad.

Caller Instructions

• Local calls within Kostanai: If you are in the same locality, you may often dial the six-digit subscriber number directly without the area code, depending on your operator's local dialing plan. However, for clarity and consistency, using the full national format is recommended.
• Calls from other regions of Kazakhstan: Dial 8, then 7149, followed by the six-digit number.
• Calls from abroad: Dial your country's international access code (e.g., 00 from most European countries, 011 from the US/Canada), then 7, then 7149, then the six-digit number. Example: from the US, you would dial 011 7 7149 123456.

Numbering and Overlay Considerations

The 7149 area code is part of the Kazakhstani numbering plan, which follows ITU-T E.164 recommendations. The total length of a national significant number (NSN) for geographic numbers in Kazakhstan is 10 digits, including the area code. There is currently no overlay in the Kostanai region, meaning that the 7149 code is the sole geographic code for this area. However, as Kazakhstan migrates to the +997 country code, subscribers in this region will eventually need to update their international dialing habits. Until then, +7 7149 remains valid and operational.

Service and Usage

Numbers under +7 7149 are primarily used for fixed-line PSTN services, including residential and business telephony. They are not portable to mobile networks, but fixed number portability within the same geographic area is possible. Businesses in Kostanai often use these numbers to establish a local presence, and international callers should be aware that calling these numbers may incur international tariffs, depending on their service provider.
