Examples
North American country subset

north-american-country-subset.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/registry/bases/radix/ui/phone-input";export default function RegionalPhoneInput() { return ( <PhoneInput defaultCountry="CA" countries={[ { code: "US", name: "United States", dialCode: "+1", flag: "🇺🇸" }, { code: "CA", name: "Canada", dialCode: "+1", flag: "🇨🇦" }, { code: "MX", name: "Mexico", dialCode: "+52", flag: "🇲🇽" }, ]} > <PhoneInputCountrySelect /> <PhoneInputField placeholder="Phone number" /> </PhoneInput> );}Pre-filled phone number
Start with an existing international phone number and matching country.
pre-filled-phone-number.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/registry/bases/radix/ui/phone-input";export default function PrefilledPhoneInput() { return ( <PhoneInput defaultValue="+551155256325" defaultCountry="BR" countries={[{ code: "BR", name: "Brazil", dialCode: "+55", flag: "🇧🇷" }]} > <PhoneInputCountrySelect /> <PhoneInputField placeholder="Enter your phone number" /> </PhoneInput> );}Custom field placeholder
Use the same custom country selector with form-specific field guidance.
custom-field-placeholder.tsx
import { PhoneInput, PhoneInputCountrySelect, PhoneInputField } from "@/registry/bases/radix/ui/phone-input";export default function ContactPhoneInput() { return ( <PhoneInput defaultCountry="US" countries={[ { code: "US", name: "United States", dialCode: "+1", flag: "🇺🇸" }, { code: "CA", name: "Canada", dialCode: "+1", flag: "🇨🇦" }, ]} > <PhoneInputCountrySelect /> <PhoneInputField placeholder="Enter a callback number" /> </PhoneInput> );}API reference
PropTypeDefaultDescription
defaultValuestring—Initial phone number value. The demo initializes this to "+14085551234".
defaultCountrystring—Initial country code used by the phone input. The demo sets this to "US".
countriesPhoneInputProps["countries"]—Custom country definitions used by the country selector. Each entry in this demo has code, name, dialCode, and flag fields.
childrenReact.ReactNode—Child phone input parts rendered inside PhoneInput, including PhoneInputCountrySelect and PhoneInputField.
placeholderstring—Placeholder passed to PhoneInputField. The demo uses "Type phone number".
Accessibility
- Provide a visible label for the phone field; the placeholder should not be the only field identification.
- Use complete country names in each country definition so the selector can communicate meaningful labels instead of relying only on emoji flags or dial codes.
- Ensure the country selector and phone field remain keyboard reachable and retain visible focus styles from the underlying components.
- When validating or submitting the field, communicate formatting and error feedback to assistive technologies through the surrounding form implementation.
