# Collecting extra profile data (eg. email address)

Collecting profile data such as email addresses and phone numbers during canvassing or calls is crucial for maintaining up-to-date supporter records. FieldEdge makes this easy by allowing you to add these questions to a survey and then syncing the data to the person's NationBuilder profile.

### How It Works

1. Decide which contact fields you'd like to capture based on the table of [supported fields here](https://guides.fieldedgeapp.com/guide-to-canvassing-and-calls/setup/adding-a-survey#native-contact-fields) (under "Native Contact Fields").
2. Create a survey in NationBuilder [following our guide](https://guides.fieldedgeapp.com/guide-to-canvassing-and-calls/setup-and-core-workflows/adding-a-survey) or edit an existing one.
3. For each contact field, create a new text question in your survey, ensuring the slug contains the value from [the supported fields table](https://guides.fieldedgeapp.com/guide-to-canvassing-and-calls/setup/adding-a-survey#native-contact-fields).

**For step-by-step instructions on setting up native fields with our advanced survey features, visit our** [**Adding a Survey**](https://guides.fieldedgeapp.com/guide-to-canvassing-and-calls/setup/adding-a-survey#native-contact-fields) **guide.**

By configuring these fields, collected data is automatically mapped to the appropriate profile fields, reducing manual entry and improving accuracy.
