Phone field

The phone field component collects phone numbers with country code formatting. Use it when you need a phone number input with built-in formatting for international numbers.

For phone numbers tied to marketing consent, use consent phone field instead.

Phone field doesn't include a built-in country-code picker — it accepts free-form text input. Implement validation in your extension and use the error prop to display results.

Anchor to PropertiesProperties

Configure the following properties on the phone field component.

Anchor to autocomplete autocomplete AutocompleteField | `${} ${AutocompleteField}` | `${} ${AutocompleteField}` | `${} ${} ${AutocompleteField}` | "on" | "off" Default: 'on': A hint about the intended content of the field for browser autofill.

When set to on (the default), this property indicates that the field should support autofill, but you do not have any more semantic information on the intended contents.

When set to off, you are indicating that this field contains sensitive information, or contents that are never saved, like one-time codes.

Alternatively, you can provide value which describes the specific data you would like to be entered into this field during autofill.

Learn more about the set of autocomplete values supported in browsers.
Anchor to defaultValue defaultValue string: The initial value of the field when it first loads. Unlike placeholder, this is a real value that the user can edit and that gets submitted with the form. Once the user starts typing, their input replaces this value.
Anchor to disabled disabled boolean Default: false: Whether the field is disabled, preventing any user interaction.
Anchor to error error string: An error message displayed below the field to indicate validation problems. When set, the field is styled with error indicators and the message is announced to screen readers.
Anchor to id id string: A unique identifier for the element. Use this to reference the element in JavaScript, link labels to form controls, or target specific elements for styling or scripting.
Anchor to label label string: The text displayed as the field label, which identifies the purpose of the field to users. This label is associated with the field for accessibility and helps users understand what information to provide.
Anchor to labelAccessibilityVisibility labelAccessibilityVisibility 'visible' | 'exclusive' Default: 'visible': Controls whether the label is visible to all users or only to screen readers.

visible: The label is shown to everyone.

exclusive: The label is visually hidden but still announced by screen readers.
Anchor to name name string: The name attribute for the field, used to identify the field's value when the form is submitted. Must be unique within the nearest containing form.
Anchor to readOnly readOnly boolean Default: false: Whether the field is read-only and can't be edited. Read-only fields remain focusable and their content is announced by screen readers.
Anchor to required required boolean Default: false: Whether the field needs a value. This requirement adds semantic value to the field, but it will not cause an error to appear automatically. If you want to present an error when this field is empty, you can do so with the error property.
Anchor to type type 'mobile' | '' Default: '': The type of phone number to collect. Specific styling may be applied to each type to provide extra guidance to users. No additional validation is performed based on the type.

Styling hint for the input keyboard. Doesn't validate the phone number format. Implement validation in your extension and use the error prop to show results.
Anchor to value value string: The current value for the field. If omitted, the field will be empty.

AutocompleteSection

The “section” scopes the autocomplete data that should be inserted to a specific area of the page. Commonly used when there are multiple fields with the same autocomplete needs in the same page. For example: 2 shipping address forms in the same page.

`section-${string}`

AutocompleteGroup

The contact information group the autocomplete data should be sourced from.

"shipping" | "billing"

Anchor to EventsEvents

The phone field component provides event callbacks for handling user interactions. Learn more about handling events.

Anchor to blur blur <typeof tagName>: A callback fired when the phone field loses focus.

Learn more about the blur event.
Anchor to change change <typeof tagName>: A callback fired when the phone field value changes.

Learn more about the change event.
Anchor to focus focus <typeof tagName>: A callback fired when the phone field receives focus.

Learn more about the focus event.
Anchor to input input <typeof tagName>: A callback fired when the user inputs data into the phone field.

Learn more about the input event.

CallbackEventListener

A typed event listener for custom element events. The listener receives a `CallbackEvent` with the correct `currentTarget` type for the associated custom element tag.

(EventListener & {
    (event: CallbackEvent<TTagName, Event> & TData): void;
}) | null

CallbackEvent

An event type that narrows the `currentTarget` to the specific HTML element associated with the custom element tag. This provides type-safe event handling in callback listeners.

TEvent & {
    currentTarget: HTMLElementTagNameMap[TTagName];
}

Anchor to SlotsSlots

The phone field component supports slots for additional content placement within the component. Learn more about using slots.

Anchor to accessory accessory HTMLElement: Additional interactive content displayed within the field. Accepts button and clickable components with text content only. Other component types or complex layouts are not supported.

Anchor to Best practicesBest practices

Use autocomplete: Set autocomplete="tel" so that browsers can suggest previously used numbers.
Pre-fill for returning buyers: To reduce friction, use defaultValue to pre-fill when the buyer's number is known.
Explain why the number is needed: Add a label or use the error property to explain to buyers why they need to enter their number. For example, "required for delivery updates."
