Frequently asked questions
Answers to common questions about the phone number formatter
E.164 is the international telephone numbering standard from the ITU (International Telecommunication Union). An E.164 number starts with a + followed by the country code without a leading zero and the subscriber number without separators. Example: +4930123456789 for a Berlin landline number. This format is expected by SMS APIs, VoIP systems and most telecommunication services worldwide.
When a number is entered without an international prefix (e.g. 030 12345678), the tool needs to know which country the number belongs to. The default country code is used to supplement the missing country information. If you enter a number with +, the tool automatically detects the country code.
The type detection (landline/mobile) is based on simple number prefixes and is therefore only implemented for some countries (e.g. Germany, Austria, Switzerland, UK). For other countries "Unknown" is shown. For accurate type detection in all countries, the Google libphonenumber library would be required.
The tool accepts phone numbers in various formats: with or without country code (+ or 00), with or without leading 0 for the area code, with spaces, hyphens, brackets or dots as separators. The number is automatically cleaned and analyzed.
The tool provides a simple validity check based on the length of the national number (4–15 digits according to ITU-T E.164). For robust validation in production systems, we recommend using the Google libphonenumber library, which provides complete country and format validation.
