To undo a deleted WhatsApp contact, restore it from your phone’s contacts backup (Google Contacts for Android or iCloud for iPhone). Once restored, it will automatically reappear in WhatsApp.

Tip: You can also check Google Contacts → Trash (within 30 days) and restore the deleted contact.

You can’t undo a deleted WhatsApp contact directly, just restore it from your phone’s contacts backup (Google Contacts/iCloud), and it will reappear in WhatsApp after syncing.

Using the contact service on your phone is the best way to retrieve a deleted contact. To get the number, check the Trash/Bin folder in your Google Contacts (Android) or restore contacts from a recent iCloud backup (iPhone). The contact will reappear in WhatsApp after it has been restored.
