How to Merge Company with HubSpot's Duplicate Management Tool 🔧
If you have a Professional-tier Hub, you get access to HubSpot’s Duplicate Management tool, which scans your CRM and flags potential duplicates. While the tool helps surface potential duplicates, suggested matches aren’t always accurate, especially for companies with similar names or shared domains.
HubSpot runs a daily scan based on:
- Contacts: First Name, Last Name, Email address, IP country, Phone number, Zip Code, and Company Name.
- Companies: Company Domain Name, Company Name, Country/Region, Phone Number, and Industry.
HubSpot shows up to 2,000 duplicate companies (or 5,000 for Data Hub Pro, 10,000 for Enterprise).
