Duplicate leads in your GoHighLevel pipeline usually result from form misconfigurations, missing unique identifiers, or automation errors. Here's how to identify the root cause and prevent it going forward.

Why are leads duplicated in GoHighLevel pipeline?
If you’re seeing the same lead appear multiple times in your GoHighLevel (GHL) pipeline, you’re not alone. While it’s frustrating, especially when you’re trying to keep your CRM clean and accurate, duplicate leads are usually caused by misconfigured forms, automation logic, or missing unique identifiers.
Let’s go step-by-step to understand why this happens—and how to stop it.
Common Reasons for Duplicate Leads in GHL
1. Form Submissions Without a Unique Identifier
GoHighLevel relies on email addresses or phone numbers to identify contacts. If someone submits a form:
- Without these fields
- Or with a new email/phone number each time
GHL treats them as a new lead every time.
What to do:
- Always collect email OR phone number in every form
- Make sure these fields are required
- Avoid allowing users to bypass form fields using autofill or placeholders
2. Custom Form Fields Not Mapped Properly
If your form includes custom fields (e.g., “Company Name” or “Project Type”) and those aren’t mapped correctly in GHL, the system might create new entries rather than updating existing ones.
What to do:
- Go to Sites > Forms > Builder
- Check your field mappings (gear icon on each field)
- Confirm each field is linked to the correct custom field in Contacts
3. Multiple Entry Points with No Deduplication
If leads are coming in from:
- A website form
- A Facebook Lead Ad
- A Zapier webhook
- Manual imports
…and these channels don’t cross-check against existing contacts, GHL creates duplicates.
What to do:
- Enable contact merge logic in workflows
- Set email or phone number as the unique identifier when importing data
- Use workflows with
Update Contact
rather thanCreate Contact
where applicable
4. Workflows Creating New Opportunities Repeatedly
Sometimes, a contact isn’t duplicated — the opportunity is. If a workflow creates a new pipeline stage every time the contact takes an action (e.g., clicks a link, fills a form again), it might seem like the lead is duplicated.
What to do:
- Add a “Contact in Pipeline?” condition before creating a new opportunity
- Use “If opportunity exists → do nothing” logic
- Use tags or custom fields to track if a lead is already in the pipeline
5. Leads Are Manually Entered with Slight Variations
If team members manually enter leads and:
- Misspell names
- Enter alternate emails or phone numbers
- Skip fields inconsistently
…GHL can’t recognize the contact and logs them as new.
What to do:
- Create a lead intake SOP for your team
- Use a standardized format for phone numbers and names
- Use the Merge Contacts option in the Contacts section to clean up duplicates
Tools to Help
- GHL Contact Merge: Go to
Contacts > Smart List > Select Duplicates > Merge
- Zapier Filters: Use filters to check for existing contact before pushing into GHL
- Workflows: Add decision logic to check for existing contacts or pipeline entries
Quick Prevention Checklist
- Always collect email or phone number (and make it required)
- Ensure forms have correct field mappings
- Add deduplication logic in your workflows
- Check multiple entry points like Zapier, FB, and GHL native forms
- Train your team to enter consistent, clean data
- Regularly audit and merge duplicate contacts in GHL
Real Example
One client was seeing triple entries for every lead. The culprit? Their website, Facebook form, and Zapier were all sending leads independently without matching email IDs. After setting the phone number as a common unique field and updating workflows, the duplication stopped completely.
