GeneralAccount and Profile

Don’t recognize contact’s account

Whenever someone switches phone numbers, you should make sure to delete their old number from your phone's address book. Since mobile providers recycle numbers, you might incorrectly identify an account in WhatsApp as your friend's account, but the number belongs to the new owner of the phone number.

WhatsApp only uses phone numbers to identify accounts and displays the names saved in your address book for those contacts.
