The phone recognizer accepts only numbers with an explicit international prefix, such as +49… or 0044…. That lets it read the calling code from the number itself instead of guessing where the user is located.

The current calling-code map prioritizes major European codes plus commonly used codes for Mainland China, Hong Kong, Macao, Taiwan, Singapore, Japan, Korea, Vietnam and the North American Numbering Plan.

1. 01Enter a number beginning with +, or use the common 00 international dialing prefix.
2. 02The tool removes spaces, parentheses, dots and hyphens, then checks the E.164 total length.
3. 03When the calling code is known, it shows the code, possible region codes and the national-number portion.

ITU-T E.164 defines the international public telecommunication numbering plan and limits an international number to at most 15 digits. A local number without a country context is ambiguous across numbering plans. Guessing a country from browser language or IP can look convenient while producing false certainty, so this tool requires the number itself to carry an international code.

• This is E.164-oriented structural recognition, not a complete national phone-number library.
• One calling code may cover several countries or territories. For example, +1 belongs to the North American Numbering Plan; the tool does not guess a specific country without deeper plan data.
• It does not determine assignment, reachability, mobile/fixed status or current carrier. Number portability makes carrier inference from prefixes particularly unreliable.
• It does not send SMS messages, place calls or query subscriber identity.

• Clean CSV or CRM fields that contain international phone numbers.
• Check whether a user supplied an explicit international-number shape.
• Read a calling code before handing the number to a more specialized numbering-plan tool.

Phone parsing runs locally in the browser. Phone numbers are personal contact information; do not enter unrelated third-party numbers, and do not treat a format match as proof of ownership or identity.
