Fictitious telephone number

A fictitious telephone number is like a pretend phone number that people make up. It's not a real phone number that you can call to talk to someone. People use these pretend phone numbers in movies, TV shows, and books to help tell a story. It's like when you play with your toys and make up stories, you might pretend that one of your toys is a phone and say a pretend phone number for your toy friend to call you on. Fictitious phone numbers are just like that but used by grown-ups to tell stories.
