Faxkennung is the German word for fax number. A fax number is a unique identifier assigned to a fax machine that allows it to send and receive faxes. Fax numbers are typically formatted as follows: [country code]-[area code]-[fax number]. For example, a fax number in the United States might look like this: 1-212-555-1212.
Fax numbers are important because they allow businesses and individuals to send and receive faxes without having to use a physical fax machine. This can be a convenient and cost-effective way to communicate, especially for businesses that need to send and receive large volumes of documents.
