Phone field (older)

Made before October 12, 2026

This page covers the Phone block, an older form block made before October 12, 2026. It keeps working and stores that use it can keep editing it, but it isn’t offered for new blocks. For a new phone field, add a Phone field to a Custom fields form, which can also set the shipping address’s phone, or use Shopify’s own phone setting under Settings → Checkout. See which kind is my form?

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 Buddy plans. Needs Shopify Plus.

Settings

Setting	What it does
Label	The field’s label. Plain text.
Customer must fill field to proceed in checkout	Makes the number required. The dial code alone doesn’t count as an answer.
Apply validation	Check the number against a pattern, such as ^\+1\d{10}$ for US and Canadian numbers. See validation.
Apply effect when value changes	Includes Apply value to shipping address phone field, which also fills in the shipping address phone.

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 Shopify’s own SMS consent option in its checkout settings, or the SMS consent block if your store installed Checkout Buddy before November 11, 2026. Both save the number to the customer’s profile.
