Phone Numbers: Fact or Fiction

As a developer, it's essential to consider how phone numbers are used in apps, as using real numbers can lead to unwanted calls and interactions with real individuals or businesses. Fortunately, many countries have designated specific ranges of phone numbers for fictional use, such as the 555 block in the US, which allows developers to use safe numbers without accidentally using a real person's or business's number. By using these designated ranges, developers can avoid potential issues and ensure their examples and demos are more realistic and less prone to prank calls or unwanted interactions.
