How To Add Phone Number Validation To The Phone Field Or A Custom Field

The native phone field in the Design Editor includes submit and display options that control how phone numbers are validated before submission and how the field appears to users. This article covers those settings.

Accessing the settings

1. Open your campaign in the Design Editor.
2. Select the Phone field in your campaign.
3. Scroll down to the Other Phone Field Settings - Here you can control the display (how the number will be shown as users type it in) and submit (how the number will be shown in the submission payload) format for phone numbers.

If a user does not enter enough digits specified in the submit format, an error will be displayed and the submission will be rejected.

Applying phone validation to a custom field

Phone number validation isn’t limited to the native phone field. You can apply the same validation formats to any custom field using the Input Options setting on that field.

1. Select the custom field in the Design Editor.
2. Enable Input Options in the field settings panel.
3. Select the phone validation format you want to apply (10 digits, 11 digits USA +1, or 11 digits global).

If you need to apply similar display and submit formatting to custom fields that are collecting phone numbers, there’s an extension for that! This page will help walk you through installing and configuring it.
