What is how to know if someone changed their number?

Here are some signs that someone might have changed their phone number:

• Communication Ceases Abruptly: One of the most obvious signs is a sudden stop in communication. If you were regularly in contact and now can't reach them, it's possible they've changed their number. Look at your message history for the last successful contact.

• Messages Not Delivering: If you send a text message and it doesn't deliver (you don't see the "delivered" notification, or you receive an error message), their old number might be disconnected. However, this can also indicate other issues like a dead phone battery or network problems, so don't jump to conclusions immediately.

• Calls Go Straight to Voicemail: Consistently being sent straight to voicemail, especially when you'd normally expect them to answer, can be a sign. Their old number may not be in service, or they may have blocked your number. See more about voicemail behavior.

• Social Media or Other Accounts Not Updated: Check if their phone number is used for any accounts where you can view the associated number (e.g., some social media profiles, ride-sharing apps, etc.). If they haven't updated those accounts, the listed number is likely outdated. Also, look at their social media activity for clues or announcements.

• Asking Mutual Contacts: If you have mutual friends or contacts, discreetly inquire whether they have the person's current number. This is often the most reliable way to confirm a number change. You can compare it with your current information.

• "Number Not in Service" Message: If you call and hear a recording stating that the number is no longer in service, or has been disconnected, it's a clear indicator they've changed it or canceled service. It is better to also check new phone number possibilities.

• Unexpected Replies: If you send a text and receive a reply from someone claiming to be a different person, they have likely been assigned the old number. Check the possibility of incorrect number.
