📍 Geographic Location of Mumbai
Overview of Mumbai Area Code 223
Area code 223 is a geographic National Destination Code (NDC) assigned to the city of Mumbai, the capital of the Indian state of Maharashtra and the financial, commercial, and entertainment capital of India. Under the ITU-T E.164 international numbering plan, the full country calling code for India is +91, and the complete international dialing format for a landline number in this area is +91 22 3XXX XXXX (or more precisely, +91-22-XXXXXXX for 8-digit local numbers; see below).
Geographic Coverage and Administration
The 22 NDC covers the entire Mumbai metropolitan region, including the island city and its suburbs, as well as parts of the Mumbai Metropolitan Region (MMR) such as Thane and Navi Mumbai. The prefix 223 is a specific central office (exchange) code within the 22 NDC, indicating a particular telephone exchange or group of exchanges in the city. It is administered by the Department of Telecommunications (DoT) of India, under the Ministry of Communications.
Dialing Formats and Numbering Structure
In the national format, local numbers in Mumbai are 8 digits long. When dialing from within India (outside Mumbai), you must prefix the area code with the trunk prefix 0, so the format becomes 022-XXXX XXXX. For example, a number with the exchange 223 might be 022-223X XXXX (where X represents the remaining digits). Internationally, callers dial +91 22 XXXX XXXX (omitting the leading 0). It is important to note that the 22 area code is an overlay for the entire Mumbai region; no additional overlay codes have been introduced, and all fixed-line numbers share the same 8-digit length.
Caller Instructions
- Local callers (within Mumbai): Dial the 8-digit subscriber number directly, without the area code. For example, if the number is 2234 5678, simply dial 2234 5678.
- National callers (outside Mumbai): Dial the trunk prefix 0, then the area code 22, then the 8-digit number: 022 2234 5678.
- International callers: Dial your country's exit code (e.g., 00 or 011), then India's country code 91, then the area code 22 (without the leading 0), then the 8-digit number: +91 22 2234 5678.
Important Considerations
As with all geographic numbers in India, fixed-line numbers in Mumbai are portable within the same geographic area (intra-circle mobile number portability is not applicable to fixed lines, but fixed-line portability is available within the same short distance charging area). When calling from a mobile phone, it is recommended to use the full national format (022-XXXX XXXX) to ensure proper routing. For international callers, always replace the leading 0 with +91.
