Overview of Area Code +7 421
Area code +7 421 is a geographic National Destination Code (NDC) assigned to the Khabarovsk Territory (Khabarovsk Krai) in the Russian Far East. This code is used for fixed-line (PSTN) and some VoIP services within the region. The territory’s administrative center, the city of Khabarovsk, is the primary hub, along with other major localities such as Komsomolsk-on-Amur, Amursk, and Sovetskaya Gavan. The numbering area covers a vast geographical expanse, reflecting the region’s strategic position near the Amur River and its border with China.
Dialing Formats and Usage
When dialing a fixed-line number in the Khabarovsk Territory from within Russia, the trunk prefix 8 is used, followed by the area code and the subscriber number. The full national format is 8 (421) XXX-XX-XX. From abroad, callers must use the international access prefix (e.g., 00 or +), the country code 7, the area code 421, and the subscriber number, resulting in +7 421 XXX-XX-XX. The subscriber number length is seven digits, making the total international number length 11 digits (including the country code).
Geographic Coverage and Local Significance
The +7 421 area code is non-geographic in the sense that it does not correspond to a single city but rather to a whole federal subject. However, it is still a geographic code tied to the Khabarovsk Territory. The region is a major industrial, transportation, and administrative center in the Russian Far East, with a population of over 1.3 million. Khabarovsk itself is the largest city and serves as the administrative center of the Far Eastern Federal District. The code is essential for businesses and residents in the region, supporting local communication and connectivity.
Overlays and Numbering Changes
As of the latest updates, there are no overlay codes for the Khabarovsk Territory. The +7 421 code remains the sole geographic area code for fixed-line services in the region. However, due to the growth of VoIP and mobile services, some numbers may be assigned to non-geographic services, but the code itself is primarily used for traditional fixed-line telephony. Callers should always verify the correct dialing format, especially when calling from mobile phones, as some mobile networks may require the use of +7 even for domestic calls.
Practical Dialing Examples
- Local call (within Khabarovsk): Dial the 7-digit subscriber number directly, e.g., XX-XX-XX.
- National call (from another Russian city): Dial 8 (421) XXX-XX-XX.
- International call (from abroad): Dial +7 421 XXX-XX-XX.
Understanding these formats is crucial for both domestic and international callers to ensure successful connection to any fixed-line subscriber in the Khabarovsk Territory.
