📍 Geographic Location of Mumbai
Geographic Coverage and Administrative Jurisdiction
Area code +91 224 is a geographic National Destination Code (NDC) assigned to the western Indian state of Maharashtra. It specifically serves the Mumbai Metropolitan Region (MMR), including the island city of Mumbai and its immediate suburbs. The jurisdiction falls under the Mumbai Telecommunication District of BSNL and the Maharashtra circle of the Department of Telecommunications (DoT). The code covers key administrative areas such as the Mumbai City district, Mumbai Suburban district, and parts of Thane and Raigad districts that are integrated into the MMR.
Primary Cities and Localities Served
This prefix routes calls to the heart of India’s financial and entertainment capital. Subscribers within this code include those in South Mumbai (e.g., Colaba, Fort, Nariman Point), Central Mumbai (e.g., Dadar, Parel), Western Suburbs (e.g., Bandra, Andheri, Juhu), and Eastern Suburbs (e.g., Chembur, Ghatkopar). It also covers the Navi Mumbai nodes of Vashi and Nerul, as well as the Thane city area, which are all part of the contiguous urban agglomeration.
Dialing Formats and Caller Instructions
For local callers within the Mumbai metro area, the standard local dialing format is the 8-digit subscriber number only, without the trunk prefix or area code. For callers from other parts of India, the dialing format is: 0 224 XXXXXXXX (where X represents the 8-digit local number). For international callers, the format is: +91 224 XXXXXXXX (or 011 91 224 XXXXXXXX when dialing from North America).
Overlay and Numbering Considerations
Mumbai operates with multiple geographic area codes due to its massive subscriber base. While +91 22 is the primary code for the city, +91 224 is an overlay code introduced to expand numbering capacity. This means that a single local calling area may have multiple codes, and callers must dial the full NDC even for local calls when the called number uses a different code. The 8-digit subscriber number length is consistent across these codes.
Technical and Regulatory Notes
All geographic numbers in India, including those under +91 224, are subject to the Telecom Regulatory Authority of India (TRAI) guidelines. They are primarily used for fixed-line PSTN services, though some VoIP and wireless local loop operators may also use them. Number portability allows subscribers to retain their number when changing operators within the same geographic area. For accurate billing and routing, always include the full international prefix when dialing from abroad.
