📍 Geographic Location of Mumbai
Geographic Context and Coverage
The +91 225 area code is a geographic National Destination Code (NDC) assigned to Mumbai, the capital city of the Indian state of Maharashtra. Mumbai is India's financial, commercial, and entertainment hub, with a population exceeding 20 million in the metropolitan region. The 225 code serves the island city and its immediate suburbs, including key business districts such as Nariman Point, Fort, Colaba, and the southern peninsula. It is one of several area codes allocated to Mumbai; others include 22 (for the main city and western suburbs) and 240 (for the eastern suburbs and Navi Mumbai). The 225 code is specifically used for landline numbers in the southern part of Mumbai, often referred to as the 'Old City' area.
Dialing Formats and Usage
When calling a landline in the 225 area from within India, you must dial the trunk prefix '0', followed by the area code and the subscriber number. For example, to reach a number in Mumbai with the local number 1234567, you would dial 0225 1234567 from any other part of India. From outside India, callers should dial the international access prefix (e.g., 00 from most countries), followed by India's country code +91, then the area code without the leading '0', and the subscriber number. Thus, the international format would be +91 225 1234567.
Local calls within the same area code can be made by dialing only the 7-digit subscriber number. However, due to the implementation of the '0' prefix for all STD calls in India since 2015, even calls between different area codes within Mumbai require the full STD code. For example, a call from a 22 number to a 225 number must be dialed as 0225 followed by the subscriber number.
Numbering and Regulatory Details
Landline numbers under the 225 code are 8 digits long in total, including the area code? Actually, the subscriber number is 7 digits, and the area code is 3 digits, making the total 10 digits for the national significant number (NSN) when including the leading '0' for domestic calls. This aligns with the 10-digit numbering plan for Indian fixed-line services. The code is administered by the Department of Telecommunications (DoT) and is allocated to Bharat Sanchar Nigam Limited (BSNL) and private operators like Reliance Jio, Bharti Airtel, and Tata Tele. Subscriber numbers may be ported to other operators, but the geographic code remains unchanged.
Caller Instructions
For callers within Mumbai, if you are dialing from a mobile phone, you must always include the area code even for local calls, as mobile numbers are not tied to geographic areas. For international callers, ensure you drop the leading '0' when dialing +91 225. For example, a call from the UK to a Mumbai number would be dialed as 00 91 225 1234567. Always verify the subscriber number length, as some older numbers may have fewer digits.
