History
The National Numbering Plan 2003 standardized ten-digit national significant numbers and organized fixed-line numbering around Short Distance Charging Areas. TRAI reviewed the plan in 2024 and issued recommendations in February 2025; proposals are not presented here as active unless adopted by the Department of Telecommunications.
Indian STD codes vary in length and cover charging areas rather than perfectly matching city or state boundaries. Number portability means mobile prefixes are not reliable indicators of the current operator.

Current operator and market-share data are dynamic. This page avoids assigning a specific number to a carrier from its area code alone.
Landline
Area code 40 is a geographic fixed-line identifier. Consult Department of Telecommunications; TRAI advises on numbering for live allocation or licensing information.
Wireless
Wireless numbers commonly use separate non-geographic ranges. Number portability prevents reliable current-carrier identification from a prefix alone.
