If you need a fictitious phone number for an example in your docs, use a North American phone number in the range +1-555-555-0100 through +1-555-555-0199. The North American Numbering Plan set aside this range of phone numbers to use in examples and in fiction.

If you need a fictitious international phone number for an example in your docs, you can use the fictitious Australian phone number of +61-2-5550-9988.

Never use a real phone number as an example.
