You can’t directly use your existing personal or business WhatsApp number to register in GoHighLevel (GHL) unless that number is first migrated or connected through the WhatsApp Business API via Meta.

When You Can Use Your Existing Number

You can use your existing WhatsApp number if all of the following are true:

• The number is not currently linked to WhatsApp Messenger or the WhatsApp Business app
  OR

• You are willing to delete your WhatsApp account from the app to free up the number for API use

• You complete the GHL WhatsApp API onboarding process 

• Meta successfully verifies and approves the number under your Business Manager (WABA)

Once connected, your WhatsApp messages will be sent and received directly inside GHL.

When You Can’t Use Your Existing Number

You cannot use your number in GHL

• The number is still active on the standard WhatsApp or WhatsApp Business app

• You want to use the same number both on your phone and in GHL at the same time — Meta does not allow this.

  A number can only be connected to one platform: either the app or the API (GHL), not both.

Recommended Options / Workarounds

Option 1: Migrate Your Existing Number

1. Delete your WhatsApp or WhatsApp Business account from the phone app.

2. During the GHL WhatsApp API setup, verify the same number.

3. Once approved, all WhatsApp messages will now be managed within GHL.

⚠️ Important: Once the number is connected to the WhatsApp API, you will no longer be able to use it in the mobile app.

Option 2: Use a New Number

• Get a new phone number for your WhatsApp API (to use with GHL).

• Keep your existing WhatsApp number active on your phone for personal or direct use.

This is often the easiest and safest option if you don’t want to lose access to your current WhatsApp app chats.
