These are sequences of digits generated without a specific pattern, intended to resemble telephone numbers within the California area code system. They are not actual assigned numbers and serve various purposes, such as testing communication systems, creating sample data for software development, or representing potential numbers in fictional scenarios.
Their usefulness lies in their ability to simulate real-world data. This allows developers to test systems’ handling of phone number formats and validate data entry processes. Furthermore, such data helps to avoid using and potentially misdialing real, assigned telephone lines during testing, which could be disruptive to service subscribers.
