Phone Number

Format and validate phone numbers

What it solves

A Phone Number pattern helps teams create a reliable way to collect telephone numbers in a format that is easy to enter, easy to review, and realistic for international use. It is most useful when teams need contact and delivery forms. Compared with adjacent patterns, this pattern should reduce friction without hiding the state, rules, or recovery paths people need to keep moving.

When to use
