Phone Field vs Contact Details Field
You may wonder:
When should I use Phone instead of Contact Details?
Use Phone field when:
You only need a phone number
You want a simple, single-purpose field
Use Contact Details field when:
You want to collect name + phone + email together
You need structured contact information in one block
Both use the same international country code selector for phone input.
When to Use the Phone Field
Use the Phone field when:
You need direct communication with users
You run WhatsApp or SMS campaigns
You verify customer identity
You follow up manually with leads
You schedule appointments
You provide service-based businesses (consulting, agencies, healthcare, etc.)
If you only need email communication, use the Email field instead. If you need both, include both fields separately for structured contact collection.
Best Practices for Collecting Phone Numbers
Make the field required only if truly necessary
Add a short description like: “We’ll only use your number for important updates.”
Avoid collecting phone numbers without clear purpose
Combine with consent (Legal Text field) when required
Clear communication improves completion rates and builds trust.
