Can A Mobile Number Have 11 Digits? Exploring Mobile Number Lengths

The Telecom Regulatory Authority of India (TRAI) has officially addressed the question of whether the country will adopt an 11-digit phone numbering system for mobile telephone services. In response to this query, as of June 1, 2020, TRAI made a clear and definitive decision. According to their recommendations, India will not transition to an 11-digit mobile numbering plan. Instead, the nation will retain its existing 10-digit numbering system for mobile phone services. This decision provides clarity and continuity in the country’s telecommunications sector, ensuring that consumers and service providers can continue to rely on the familiar 10-digit phone numbers for the foreseeable future.

Is it possible for a mobile number to have 12 digits? Phone number formats vary from country to country, with most countries using phone numbers that range from 7 to 11 digits. However, it’s important to note that certain countries have introduced longer phone numbers, which can include up to 12 digits. This variation in phone number length is primarily due to differences in country-specific numbering plans and telecommunications regulations.
