How to Update Existing Phone Numbers for Contacts in HubSpot

·Jun 17, 2025 05:30 PM·

Hello! I’m struggling to update phone numbers for contacts that already exist in HubSpot. I am doing “Update Object” in HubSpot, have the HubSpot ID as the email column, and the Object as “mobile phone” mapped to the mobile phone column. Can you help?

To update phone numbers for existing HubSpot contacts: 1. Add the "Update object with HubSpot" enrichment 2. Select "Contact" as the Object type 3. Use the column containing HubSpot IDs as the "HubSpot Object ID" input 4. Map your phone number column to "Contact Phone - Mobile" 5. Enable "Ignore blank values" if needed The HubSpot ID should be the actual ID number, not the email address. If you only have emails, first use the "Lookup object" action to retrieve the HubSpot IDs.
