The phone number is automatically saved during checkout. Consent phone fields support the `sms-marketing` policy and built-in number formatting. For general phone number collection without consent tracking, use [phone field](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/forms/phone-field) instead. Only the `sms-marketing` policy is supported. Other consent types aren't available through this component. ### Support Targets (29) ### Supported targets *

phone numbers for text message marketing tied to the `sms-marketing` policy. * **Pre-filled numbers:** Display a default phone number so returning buyers can confirm without retyping. * **Required contact info:** Validate that a phone number is provided before the buyer completes checkout. * **Automatic persistence:** Rely on the component to save the phone number during checkout without additional logic. *** ## Properties Configure the following properties on the consent phone field component. * **autocomplete** **AutocompleteField | \`${AutocompleteSection} ${AutocompleteField}\` | \`${AutocompleteGroup} ${AutocompleteField}\` | \`${AutocompleteSection} ${AutocompleteGroup} ${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](https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill-detail-tokens) supported in browsers. * **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. * **disabled** **boolean** **Default: false** Whether the field is disabled, preventing any user interaction. * **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. * **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. * **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. * **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. * **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. * **policy** **'sms-marketing'** The policy for which buyer consent is being collected. Used by the [consent checkbox](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/forms/consent-checkbox) and [consent phone field](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/forms/consent-phone-field) components to identify the type of marketing permission requested. * `sms-marketing`: Represents the policy for SMS marketing consent. * **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. * **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. * **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. * **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. ```ts `section-${string}` ``` ### AutocompleteGroup The contact information group the autocomplete data should be sourced from. ```ts "shipping" | "billing" ``` ### Events The consent phone field component provides event callbacks for handling user interactions. Learn more about [handling events](https://shopify.dev/docs/api/polaris/using-polaris-web-components#handling-events). * **blur** **CallbackEventListener\** A callback fired when the consent phone field loses focus. Learn more about the [blur event](https://developer.mozilla.org/en-US/docs/Web/API/Element/blur_event). * **change** **CallbackEventListener\** A callback fired when the consent phone field value changes. Learn more about the [change event](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/change_event). * **focus** **CallbackEventListener\** A callback fired when the consent phone field receives focus. Learn more about the [focus event](https://developer.mozilla.org/en-US/docs/Web/API/Element/focus_event). * **input** **CallbackEventListener\** A callback fired when the user inputs data into the consent phone field. Learn more about the [input event](https://developer.mozilla.org/en-US/docs/Web/API/Element/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. ```ts (EventListener & { (event: CallbackEvent & 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. ```ts TEvent & { currentTarget: HTMLElementTagNameMap[TTagName]; } ``` ### Slots The consent phone field component supports slots for additional content placement within the component. Learn more about [using slots](https://shopify.dev/docs/api/polaris/using-polaris-web-components#slots). * **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. *** ## Examples ### Collect a phone number for SMS consent Display a phone number field for SMS marketing consent with a pre-filled value. This example uses an `s-consent-phone-field` with `policy` set to `sms-marketing` and a `defaultValue`. ## Collect a phone number for SMS consent ![A rendered example of the consent-phone-field component](https://shopify.dev/assets/assets/images/templated-apis-screenshots/checkout-ui-extensions/2025-10/consent-phone-field-default-BvFHV8EV.png) ## html ```html ``` ### Require a phone number for SMS consent Validate that a phone number is provided before the buyer opts in to SMS marketing. This example presents a consent phone field with `required` and an error message for missing input. ## html ```html ``` ### Customize the phone field label Clarify what the phone number is collected for by customizing the label. This example displays an `s-consent-phone-field` with a label explaining SMS updates. ## html ```html ``` *** ## Best practices * **Write clear labels explaining the purpose:** Provide labels to explain why the phone number is being collected and what messages they'll receive. * **Pre-fill when available:** Use `defaultValue` to display a known phone number so customers can confirm without retyping. * **Pair with consent checkbox:** Use the [consent checkbox](https://shopify.dev/docs/api/checkout-ui-extensions/latest/web-components/forms/consent-checkbox) alongside this component to collect explicit marketing consent. * **Use supported policies:** For SMS marketing, set `policy` to `sms-marketing` so that Shopify can track consent automatically. ***
