How to Manage Duplicate Contacts in GoHighLevel
By Marnix Geerkens. Published 2025-09-16. Updated 2026-06-02.
GoHighLevel gives you a global toggle to allow or block duplicate contacts created through forms and Zapier connections. When duplicates are blocked, the CRM updates the existing record instead of creating a new one, matching first by phone or email depending on your preference. For contacts already doubled up, a manual merge tool lets you pick which data points to keep, handling up to 10 contacts at once.

Summary. The contact deduplication setting in GoHighLevel applies to inbound contacts arriving via forms or Zapier, not to CSV uploads (those go through a separate import flow). Turning the toggle off prevents new duplicate records and lets you choose whether the system matches on phone number first or email first. When you need to clean up existing duplicates, select up to 10 contacts and use the merge tool to decide field by field which version of the data to keep.
