faxNumber

FaxNumber is a string of characters representing a telephone number used for transmitting documents via a fax machine or a fax server. It typically consists of a series of digits, often preceded by an international dialing code, a country code, and an area code. Special characters such as hyphens, spaces, and parentheses may be used to improve readability, but are generally ignored by the fax transmission system.

The format of a fax number can vary significantly depending on the geographical location. For example, a fax number within the United States might follow the pattern (XXX) XXX-XXXX, while an international fax number would begin with a '+' followed by the country code and then the local number. Some fax systems also allow for the inclusion of extension numbers, which are appended to the main fax number, often separated by a comma or the letters "ext.".

In software development, a faxNumber is commonly stored as a string data type. Input validation is often implemented to ensure that the entered fax number conforms to expected patterns or character sets. Some applications may offer features to format or validate fax numbers automatically. The functionality of sending and receiving faxes is often integrated into software solutions, requiring a valid fax number to initiate or receive a transmission.
