Phone Number

A phone number input with optional country code and format validation.

Overview

The Phone Number field provides a dedicated input for telephone numbers. On mobile it triggers a numeric keyboard. You can configure it to accept international format (with country code prefix) or a specific national format using the pattern validation.

DynamicFormBuilder also supports Nepali number input via the nepali flag, which renders a Nepali-script numeral input widget for deployments targeting Nepali-speaking users.
