Phone Number Analyzer
The phone formatter validates and normalizes international phone numbers according to the E.164 standard and country-specific formatting rules. Enter a phone number in any format and the tool returns its canonical E.164 form, national format, international format, country code, and country name. It supports over 200 countries and regions.
What is the Phone Number Formatter?
The phone formatter is a tool for parsing, validating, and reformatting telephone numbers from around the world. Different countries have different rules for how phone numbers are written — national vs international dialing, area code conventions, and local format variations. The tool uses the libphonenumber standard (developed by Google) to normalize any input into a canonical form and validate whether the number is structurally possible for the indicated country.
How does it work?
Enter a phone number with or without country code. If you do not include a country dial prefix, select the default country from the dropdown. The parser identifies the country, strips formatting characters, validates the number length and pattern, and outputs it in multiple standardized formats: E.164 (+49891234567), national (089 1234567), and international (+49 89 1234567). Invalid numbers are reported with an explanation of why they fail validation.
Typical Use Cases
- Normalizing phone numbers to E.164 format before storing in a database
- Validating customer-submitted phone numbers in a web form
- Formatting a phone number for display according to local conventions
- Parsing a mixed-format phone number list from an imported CSV file
Step-by-step Guide
- Step 1: Enter the phone number in any format (with or without spaces, dashes, or parentheses).
- Step 2: Select the default country if the number does not include a dial prefix.
- Step 3: Click Format to validate and parse the number.
- Step 4: Copy the E.164, national, or international format as needed.
Example
Input
(089) 123-4567, Country: Germany
Output
E.164: +4989123456 | National: 089 123456 | International: +49 89 123456
Tips & Notes
- Always store phone numbers in E.164 format in your database — it is the universally unambiguous form.
- E.164 numbers start with + followed by the country code and subscriber number, with no spaces or formatting.
- Validate phone numbers at input time, not at use time — invalid numbers stored in a database cause downstream problems.
Frequently Asked Questions
What is E.164?
E.164 is the ITU-T standard for international telephone numbering. It defines numbers as a + sign followed by up to 15 digits, including the country code and subscriber number, with no spaces or punctuation. Most telephony APIs and SMS services require E.164 format.
Can the formatter detect the carrier or line type?
The formatter can determine whether a number is a mobile, landline, toll-free, or premium rate number based on number range databases, though carrier assignment may not be available for all regions.
