Add Multiple Domain Names to a Company Record in Hubspot

Managing complex B2B accounts becomes easier when Hubspot lets you associate multiple domain names with a single company record. This is essential when your customers operate several websites or regional domains, and you want contacts and deals to roll up to the right account.

This how-to guide walks you through configuring company properties, adding extra domains, and understanding how company domain behavior affects associations and matching inside your CRM.

How Hubspot Uses Company Domain Names

Before you add extra domains, it helps to understand how the primary Company domain name property works in Hubspot:

• It is used for automatic association of contacts and companies based on email domain.
• It supports account-based sales workflows and lead routing.
• It can be treated as a unique identifier for companies when configured correctly.

Many organizations use multiple web properties, regional URLs, or legacy domains. By supporting several domains on one record, Hubspot keeps your account hierarchy clean and reduces duplicate companies.

Configure Company Domain Settings in Hubspot

Start by confirming that the Company domain name property is configured to behave as you expect in your Hubspot CRM settings.

Step 1: Open company property settings in Hubspot

1. In your Hubspot account, click the settings icon in the main navigation bar.
2. In the left sidebar, navigate to Properties.
3. Use the search box to find Company domain name.
4. Click the property name to open its configuration panel.

Step 2: Control automatic company creation

In the property editor, you can decide whether Hubspot should automatically create companies based on the domain value:

• Create and associate companies with contacts from email domains.
• Or disable auto-creation if you prefer manual company management.

This setting directly influences how contact records are grouped into companies when new leads enter your database.

Step 3: Decide how Hubspot treats uniqueness

Within the same configuration panel, review how uniqueness is handled:

• You can allow multiple companies to share the same domain, or
• Require unique values for this property across company records.

For organizations with subsidiaries or brand domains, you may want flexibility. For strict account-based structures, setting the property as unique helps keep your Hubspot data dependable and easier to report on.

Add Multiple Domain Names to One Company in Hubspot

Once your property behavior is set, you can add more domains to an existing company. Hubspot supports these additional domains through a dedicated field on the company record.

Step 1: Navigate to the target company record

1. In Hubspot, go to CRM > Companies.
2. Search for the company you want to update.
3. Click the company name to open its record.

Step 2: Locate the domain section on the company record

On the left panel of the company record, find the Company domain name field. Depending on your configuration and layout, you may also see a dedicated area for managing multiple domains.

If necessary, customize the company sidebar to make sure the domain fields are visible and easy for your team to update in Hubspot.

Step 3: Add secondary domains

To associate more domains with the same company:

1. Hover over the domain section and click Edit or the pencil icon.
2. In the additional domains field, enter each extra domain one by one.
3. Press Enter or use the on-screen control to confirm each domain.
4. Click Save to update the record.

Examples of useful additional domains include:

• Regional sites such as company.co.uk, company.de
• Legacy domains used for email only
• Brand or product-specific domains that belong to the same parent company

How Multiple Domains Affect Matching in Hubspot

Adding extra domains changes how Hubspot interprets contact and company relationships. This helps you avoid fragmented data and maintain a single source of truth.

Contact-to-company associations

When a new contact enters your CRM:

• Hubspot reads the email domain (e.g., @branddomain.com).
• It checks both the primary and additional company domains.
• If there is a match, the contact is associated with that company record.

This way, all contacts from different but related domains can roll up to the same account, keeping your company timelines, deals, and activities centralized.

Company creation and deduplication

If automatic company creation is enabled, Hubspot uses the combined set of primary and additional domains to reduce duplicates. When an incoming contact uses a secondary domain that is already stored on a company record, Hubspot is less likely to create a new, unnecessary company.

This supports stronger deduplication and more accurate company-level analytics across the entire customer lifecycle.

Best Practices for Managing Domains in Hubspot

To keep your CRM clean and dependable, follow these practical guidelines when working with multiple domains:

• Maintain one parent record for the main account when possible, and store regional or brand domains in the additional domains section.
• Document rules on which domains belong to which company, and share this with operations and sales teams.
• Review domains regularly to remove obsolete URLs and add new acquisitions or rebranded properties.
• Align integrations so that tools connected to Hubspot respect the same domain mapping logic.
