What is the Phone field?

What is the Phone field?

It’s designed for:

  • Lead generation forms

  • Contact and inquiry forms

  • Event registrations

  • Support requests

  • Appointment bookings

  • SMS or WhatsApp follow-ups

Instead of collecting phone numbers in a basic text box, the Phone field ensures consistent formatting and country-based validation for better data accuracy.


How to Add a Phone Field

  1. Open your form in the Form Builder

  2. Click + Add Content

  3. Select Phone Number under Contact Information

  4. The field will be added to your form

  5. Click the field to configure it from the Answer Panel


How the Phone Field Looks to Respondents

In the live form (respondent view), the Phone field includes:

  • A country flag selector (dropdown)

  • Automatic country dialing code

  • Structured phone number input

  • Clean, formatted display

Respondents can:

  • Search and select their country

  • Automatically apply the correct country code

  • Enter their number in a guided format

This reduces formatting errors and improves submission quality.


Configuring the Phone Field (Answer Panel)

When you select the Phone field in the builder, you can configure it from the Answer Panel on the right.

  1. Required Field

You can toggle Required field ON or OFF.

  • ON → Respondents must enter a phone number before submitting

  • OFF → Phone number becomes optional

Use required mode when:

  • You need to call respondents

  • You send SMS confirmations

  • You verify leads manually


  1. Country Code Selection

The Phone field includes a built-in country selector:

  • Displays flag icons

  • Includes search functionality

  • Automatically applies dialing code

  • Supports international numbers

This works similarly to modern international phone input systems, ensuring accurate and globally compatible data collection.

Respondents can:

  • Search for their country

  • Switch country codes

  • Enter numbers correctly formatted per region


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.


Summary

The Phone field in Kiwiform helps you collect accurate, internationally formatted phone numbers with built-in country code selection and validation. It ensures structured data, reduces formatting errors, and improves communication workflows for SMS, calls, and messaging campaigns.
