Dialing Code to Country Info

About this calculator

This tool reverse-looks-up an international dialing code (the country calling code assigned under the ITU-T E.164 numbering plan, such as +90 or +1) and returns the country it belongs to, along with its capital city and official currency. Some codes are shared by multiple territories (like +1 across the US, Canada and Caribbean nations under the North American Numbering Plan), in which case the tool shows the relevant matches.

Call center agents and customer-support teams use it to sanity-check where an inbound caller is from, travelers and expats use it to figure out how to correctly dial or save an unfamiliar international number, and developers use it as a quick reference when building phone-number validation, formatting, or country-selector logic. Import/export businesses and VOIP providers also rely on it to route or price international calls correctly.
