Phone field

The Phone block adds a phone number field that starts with the dial code for the customer’s shipping country, such as +1.

Available on the Free and Business plans. Needs Shopify Plus.

Not available on newer installs

The Phone block isn’t offered to stores that installed Checkout Buddy on or after 1 February 2026. Stores that already use it can keep using and editing it. As an alternative, use a Text field with validation, or Shopify’s own phone setting under Settings → Checkout.

Settings

Setting	What it does
Label	The field’s label. Plain text.

Things to know

• The dial code isn’t saved until the customer types a number.
• The number is saved as typed. Use validation if you need a consistent format.
• To collect a phone number for SMS marketing consent, use the SMS consent block instead. It saves the number to the customer’s profile.
