The description field on your contact properties is an internal field that can be used to add notes to your properties. This can be useful if there are multiple HubSpot users in your company and/or if you create a lot of custom properties and would like to be able to define each property and how it is used.
- Navigate to Contacts > Contact Settings.
- Locate the contact property in question, click on the Gear Icon > select Edit to change the description.
- Edit the description accordingly, and click Save property to save your edits.
You can also hover over any contact properties that appear in the About card on a contact's record to see the description for that property. This gives your team a reference point for how each property is used and how it is defined within your organization.
