For this reason, you should delete phone numbers from old contacts on WhatsApp.

When using WhatsApp , you've probably never considered how many people you actually talk to on Meta's instant messaging network. Perhaps you have a ton of contacts, but you don't even communicate with half or even a quarter of them.

Just like when we have old photos taking up space, it's always helpful to clean them up from time to time. The same thing happens with contacts, as older ones may have changed numbers and are now people you don't know. which can bring you some trouble.

This is why you should delete contacts from strangers on WhatsApp.

Many carriers may reuse numbers that previously belonged to other people . This could be for a variety of reasons, from the person canceling the service or simply deactivating it, meaning a number belonging to one of your contacts could belong to someone you don't know .

On WhatsApp, this number will appear with the name of the contact you had saved before . Even if you've never spoken to them, it will appear on your phone with that contact's name, which could easily be a friend or family member, and which now belongs to someone you don't know.

So, when a friend or someone you know notifies you that they're changing their number, it's best to delete it and add the new one to avoid any privacy issues.
