GOV.UK Design System Phone numbers pattern
Documents collecting phone numbers only when genuinely needed, offering contact choice, clear UK, international, or mobile labels, purpose hints, type tel, autocomplete tel, field-specific errors, familiar entry formats, avoiding input masks, avoiding confusing reformatting, and careful tel link behavior.
Pattern Decisions This Source Supports
| Pattern | Supported decision | Required contract | Claim note |
|---|---|---|---|
| Confirm phone | Choose confirm phone when the product must prove that the user can receive a time-limited text-message or voice code at an already captured number. | The confirmation page states why phone access is required, what channel was used, and what phone number is being confirmed when disclosure is safe. | GOV.UK phone-number guidance supports collecting phone details only when needed and separates phone entry from access confirmation. |
| Phone number entry | Choose phone number entry when the product genuinely needs a telephone route for calls, SMS messages, identity recovery, service contact, delivery coordination, support callbacks, or account verification. | Users can type, paste, autofill, edit, select, undo, and correct the phone value through native input behavior. | GOV.UK supports needed-only collection, contact choice, clear UK/international/mobile labels, purpose text, type tel, autocomplete tel, specific errors, familiar formats, avoiding masks, and avoiding confusing reformatting. |
