Common Formats for Phone Number in JavaScript

When it comes to formatting phone numbers in JavaScript, there are several common formats that you might encounter. Knowing these formats can help you write more effective code and ensure that your phone numbers are displayed correctly.

1. International Format

The international format for phone numbers begins with a plus sign (+) followed by the country code, area code (if applicable), and local phone number. For example: +1 555-123-4567. This format is commonly used for global communication and is recognized by most countries.

2. National Format

The national format for phone numbers varies by country but usually includes the area code (if applicable) and local phone number. For example: (555) 123-4567 in the US. This format is commonly used for domestic communication.

3. E.164 Format

E.164 is an ITU-T recommendation for the international public telecommunication numbering plan. It specifies the format of phone numbers used internationally and has become a standard format in many countries. The format includes the plus sign (+) followed by the country code and local phone number. For example: +15551234567.

4. RFC3966 Format

RFC3966 is a format for phone numbers specified by the Internet Engineering Task Force (IETF). It includes the phone number, the phone context (such as a trunk prefix or extension), and the dialing parameters for the call. For example: tel:+1-555-123-4567;ext=1234.

By understanding these common formats for phone numbers in JavaScript, you can improve the functionality and user experience of your applications.
