Area Code 2057 – Auchi

Geographic Overview

The Nigerian area code +234 2057 is a geographic National Destination Code (NDC) assigned to the city of Auchi, located in Edo State, south-south Nigeria. Auchi is a significant commercial and administrative hub in the northern part of Edo State, serving as the headquarters of the Etsako West Local Government Area. The code covers the Auchi metropolis and its immediate environs, including neighboring towns such as Iyekhei, Uzairue, and South Ibie. This geographic code is part of the Nigerian numbering plan administered by the Nigerian Communications Commission (NCC) under the ITU-T E.164 standard.

Dialing Formats

Understanding the correct dialing sequence is essential for both local and international callers.

• Local calls (within Nigeria): Dial 02057 followed by the subscriber's 5-digit local number. For example, to call a landline in Auchi with the local number 12345, you would dial 02057 12345 from other parts of Nigeria.
• International calls (from outside Nigeria): Dial your country's international access prefix (typically 00 or +), then Nigeria's country code 234, then the area code without the leading zero, and finally the subscriber number. For instance, from the United States, you would dial 011 234 2057 12345 or simply +234 2057 12345 from a mobile phone.
• Within Auchi (local area): In many fixed-line networks, local calls within the same exchange may require only the 5-digit subscriber number, but this depends on the operator's dialing plan. It is advisable to use the full national format 02057 + number for consistency.

Geographic Allocation and Overlays

As a geographic code, +234 2057 is tied to the physical location of the fixed-line infrastructure. This means that the number is associated with a specific exchange in Auchi, and the call routing is based on the destination's geographic location. There are currently no overlay codes in Auchi, meaning that the 2057 prefix is unique to this area. However, with the increasing adoption of VoIP and fixed wireless services, some operators may route calls using this code to non-traditional infrastructure, but the geographic association remains for regulatory and numbering purposes.

Caller Instructions

• For local callers: Always include the trunk prefix 0 when dialing from outside the Auchi area. For example, from Lagos, you would dial 02057 12345.
• For international callers: Omit the trunk prefix 0 and use the country code. For example, from the UK, dial 00 234 2057 12345 or +234 2057 12345.

This code is essential for businesses and residents in Auchi who require a fixed-line presence. For accurate billing and connectivity, always verify the subscriber number length, as Nigerian fixed-line numbers typically consist of 5 digits after the area code, making the total national significant number (NSN) 8 digits (excluding the trunk prefix).
