Sending an international fax uses the same procedure as sending a domestic fax; the only difference is in the amount of numbers you enter. To indicate to a phone/fax system that you want to send something outside the United Kingdom, you’ll add 00, then the country code, city code (akin to our area code) and fax number. The country code for Germany is 49.
Write down the full sequence of numbers, if you have not already.
Identify any missing parts in your fax number and add them. For example, the number 00-49-5555 does not have a city code. You must dial 00, which is the international code and 49, which is the country code for Germany. The city code comes before the actual phone number.
Verify that the city code you dial does not have a zero or, that when you dial, you don’t include the zero. For example, the city code for Stuttgart might look like 0711 or 711; in either case, you’d dial 711.
Send the fax as you normally would, except dial 00-49-city code-number. For example, 00-49-711-5555.
If you have to dial an authorisation code to get an outside line, such as on an office system, dial the code first according to the office’s instructions. On many office systems this is a "0." Note that while some European numbers have seven digits, others may have anywhere from five to eight.
