All you need to do is read the blog carefully and follow the steps that we are going to mention.

Causes of Duplicate Contacts in WhatsApp

Duplicate contacts appearing on WhatsApp can be really frustrating and is usually caused by a number of different reasons. Here are the most common reasons:

Multiple Contact Sources: WhatsApp reads contacts from your mobile phone’s contact list, which may be synced from Google accounts, SIM card, phone storage, and elsewhere. If the same person appears in multiple sources, you may see duplicates unless those entries are linked correctly.
Contacts Not Merged: Contacts with the same name and number may exist separately in different accounts, such as Google + SIM. If they are not linked correctly, WhatsApp may show them as separate entries.
WhatsApp Permission or Sync Issues: If your WhatsApp has outdated or unsynced contacts, it may show duplicates until it updates.
SIM Card Contacts: The SIM card often stores contacts separately without any name or formatting. If both your mobile phone and SIM card contacts are in use, duplicates may appear in your WhatsApp account.
Import/Export Errors: If you imported your contacts in CSV or VCF format, they may contain duplicates.
