Installation

pnpm dlx shadcn@latest add https://diceui.com/r/radix-vega/phone-input.json

Usage

usage.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/components/ui/phone-input";<PhoneInput name="phone">  <PhoneInputCountrySelect />  <PhoneInputField /></PhoneInput>
  • Collect international phone numbers in registration, checkout, contact, or profile forms.
  • Use when users need to select a country independently or search a large country list.
  • Use when the submitted value should be normalized to digits with a leading plus sign while showing readable grouped formatting.
  • Use the compound parts when the country selector and phone field need to be arranged within a custom layout.

Examples

Controlled value

Control the normalized phone value and receive updates through onValueChange.

controlled-value.tsx
import * as React from "react";import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/components/ui/phone-input";export function ControlledPhoneInput() {  const [phone, setPhone] = React.useState("+14155552671");  return (    <PhoneInput value={phone} onValueChange={setPhone} name="phone">      <PhoneInputCountrySelect />      <PhoneInputField aria-label="Phone number" />    </PhoneInput>  );}

Default country and validation

Set an initial country and expose an invalid state to assistive technology and visual styles.

default-country-and-validation.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/components/ui/phone-input";export function ValidatedPhoneInput() {  return (    <PhoneInput defaultCountry="US" invalid name="phone" aria-describedby="phone-error">      <PhoneInputCountrySelect />      <PhoneInputField aria-label="Phone number" />    </PhoneInput>  );}

Disabled input without flags

Disable both compound controls and hide country flags.

disabled-input-without-flags.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/components/ui/phone-input";export function DisabledPhoneInput() {  return (    <PhoneInput disabled showFlag={false} defaultValue="+442071838750">      <PhoneInputCountrySelect />      <PhoneInputField />    </PhoneInput>  );}

Read-only form field

Render a read-only phone value while preserving the hidden form control.

read-only-form-field.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/components/ui/phone-input";export function ReadOnlyPhoneInput() {  return (    <PhoneInput readOnly name="phone" defaultValue="+81312345678">      <PhoneInputCountrySelect />      <PhoneInputField aria-label="Phone number" />    </PhoneInput>  );}

API reference

defaultValuestring | undefined""Initial normalized phone value for uncontrolled usage.
valuestring | undefinedundefinedControlled normalized phone value. User input is reduced to digits and a leading plus sign before onValueChange is called.
onValueChange(value: string) => voidundefinedCalled when the normalized phone value changes.
defaultCountrystring | undefined""Initial country code for uncontrolled usage.
countrystring | undefinedundefinedControlled country code. Built-in country codes are uppercase ISO 3166-1 alpha-2 codes such as "US" or "JP".
onCountryChange(country: string) => voidundefinedCalled when the selected country code changes.
countriesCountry[] | undefinedgetCountries()Replaces the built-in country list. Each item must have code and name strings, a dialCode string, and may have a flag string. Country is an internal interface and is not exported.
namestring | undefinedundefinedName for the visually hidden native input used to submit the normalized value in a form.
placeholderstring | undefined"Enter phone number"Placeholder passed to PhoneInputField.
asChildboolean | undefinedundefinedUses Radix Slot for the root element instead of rendering a div.
disabledboolean | undefinedundefinedDisables the country trigger and phone field, adds the disabled data state, and disables the hidden form input.
readOnlyboolean | undefinedundefinedMakes the phone field read-only and sets the hidden form input to readOnly.
requiredboolean | undefinedundefinedSets required and aria-required on the field and the hidden form input.

PhoneInputCountrySelectPhoneInputCountrySelectPropsnullCountry selector compound component. Extends React.ComponentProps<typeof Popover> and additionally accepts the PopoverTrigger disabled and className props. Must be rendered inside PhoneInput.
PhoneInputFieldReact.ComponentProps<"input">nullTelephone field compound component. Accepts all native input props. Its type is always tel and its inputMode is always tel; disabled, readOnly, required, onChange, className, and ref are composed with root behavior.
PhoneInputField.onChangeReact.ChangeEventHandler<HTMLInputElement> | undefinedundefinedRuns before internal state handling. Calling event.preventDefault() prevents the internal value update. The field ignores changes while disabled or read-only.
PhoneInputField.disabledboolean | undefinedundefinedCombines with the root disabled prop using logical OR.
PhoneInputField.readOnlyboolean | undefinedundefinedCombines with the root readOnly prop using logical OR.
PhoneInputField.requiredboolean | undefinedundefinedCombines with the root required prop using logical OR.

Accessibility

  • The root renders with role="group" and exposes data-disabled, data-invalid, and data-readonly states for styling.
  • The phone field renders as type="tel" with inputMode="tel" and propagates aria-required, aria-invalid, disabled, readOnly, and required.
  • The root creates a visually hidden native input for form submission when used in a form; its value is the normalized phone value, not the display-formatted value.
  • The country selector uses a Popover and Command list with search, empty-result text, selectable country items, and focus returned to the phone field after selection.
  • Provide an accessible name for PhoneInputField with a visible label, aria-label, or aria-labelledby; the component does not generate a label automatically.
  • If using invalid, associate external help or error text with the field through aria-describedby.
