HubSpot uses the Company domain name property value to differentiate between company records. It's also used to associate contact records to company records, if automatic association is enabled.

If you work with a potential customer whose company has multiple domain names, you should add all the domain names to one company record. This helps activities from associated contacts with different email domains appear in the same company record's timeline. Learn more about having multiple domain names in a company record.

For example, when a company record has both hubspot.com and inbound.org as their company domain names, any form submissions from either email domain will be logged on the same company record and contacts with either email domain will be associated to the same company record when automatic association is enabled.

You can also explore creating parent-child company associations. However, parent-child company associations do not transfer or share data (e.g., activities) between the records.

Please note: if you add an additional domain name to a company record, and a company record already exists with that domain name, this will not merge the records or pull the activities in both company records together. Additional company domain names only apply going forwards. Learn how to merge companies.
