International dialling codes for every country. Search by country name or by code (e.g. "+91" → India). Useful for making international calls and form validation.
International subscriber dialling (ISD) codes - also called country calling codes - are numerical prefixes assigned by the International Telecommunication Union (ITU) under the E.164 standard to route telephone calls across national networks. The system was standardised in 1960 and has been maintained ever since. India's country code is +91, assigned as part of the Zone 9 (South Asia) block. When dialling internationally from India, you first dial 00 (the international access code), then the destination country code, then the local number.
With over 32 million Non-Resident Indians (NRIs) in countries ranging from the USA (+1) and UAE (+971) to the UK (+44), Canada (+1), and Australia (+61), international calls are a daily necessity for millions of Indian families. India's telecom market had over 1.17 billion mobile subscribers as of 2024 (TRAI data), and international calling plans from Airtel, Jio, and BSNL are among the most competitively priced globally. Businesses exporting to or importing from foreign markets must also verify dial codes for invoice contact details, KYC documentation under FEMA rules, and customer service portals.
