# Create Custom Fields for Surveys
Custom fields are used with surveys to gather pieces of information about your partners. For example, if you frequently have use for collecting the date of birth of your partners, you can create a birthday custom field using the *date picker* question type.
#### Create custom fields
1. From the top navigation bar, select  **\[User profile]** → [**Settings**](https://app.impact.com/secure/advertiser/account-settings-flow.ihtml).
2. On the right under **Program**, go to the *Technical* section and select **Custom Fields**.
3. In the upper-right corner, select **Create Custom Fields**.
4. Complete the custom field information:
* **Name:** Add a name to easily recognize this custom field when adding fields to a survey.
* **Description:** Add a description for your custom field to describe the data representing the custom field. This description won't be visible to the partner.
* **Display Type:** Choose the question type that would best capture the data for which you are looking.
