How to Find Duplicates in HubSpot Using the Search Bar 🔍

If you're actively working in your CRM, HubSpot's global search bar can help you find duplicates on the fly. While this is a reactive approach, it’s useful for quick checks when you're already searching for a specific record.

Steps to Find Duplicates using Search:

1. Use the search bar in the top navigation to look up a contact, company, deal, or ticket.

2. Look for multiple results with the same or similar names.
   
   

3. Open one of the duplicate records.

4. In the top left of the record page, click Actions → Merge.
   
   

   
   
   

✅ Pros:

• Simple for merging individual records on the fly

• Helpful when actively working on a record

❌ Cons:

• Reactive, not proactive

• Manual effort that doesn’t scale well
  
  

How to Find Duplicates in HubSpot with the Duplicate Management Tool 🔧

If you're on a Professional or Enterprise plan, you can use HubSpot’s Duplicate Management tool, which automatically scans your CRM for potential duplicates. HubSpot does not allow you to customize which properties are used for duplicate detection, and duplicate scans run once per day.

How HubSpot Finds Duplicates:

• Contacts: Uses a combination of properties such as First Name, Last Name, Email, IP Country, Phone Number, Zip Code, and Company Name.
• Companies: Matches on Domain Name, Company Name, Country/Region, Phone Number, and Industry.

• Up to 2,000 duplicates (Professional)
• Up to 5,000 with Operations Hub Pro
• Up to 10,000 with Enterprise
  
  

Steps to Use the Duplicate Management Tool

1. Start by navigating to the duplicate management tool via Contact or Companies → Actions → Manage Duplicates
   
   
   

   
   

2. Select either the Contacts or Companies tab to review potential matches

   

✅ Pros:

• Automatically scans your HubSpot for duplicates

• No setup or configuration required

❌ Cons:

• Limited transparency into how duplicates are detected

• Capped number of duplicates shown

• Scans run only once per day

• Only available for contacts and companies (not deals or tickets)
