Require Phone at Checkout

Every WhatsApp message WhatPro sends needs a phone number to reach the customer. If your checkout does not require a phone number, some orders arrive without one, and those customers cannot receive order confirmations, shipping updates, or recovery messages. Requiring the phone number at checkout ensures every order comes in with a usable number.

Set the phone number to required

The setting lives in Shopify, not in WhatPro.

1. In your Shopify Admin, open Settings then Checkout.
2. Find the Customer information section.
3. For the shipping address phone number, set it to Required.
4. Save.

After this change, customers must enter a phone number to complete checkout, so new orders carry one automatically.

Tip

The Require phone at checkout step on the WhatPro dashboard checklist links straight to your Shopify checkout settings.

Why this matters

Without a required phone number	With a required phone number
Some orders have no number	Every order has a number
Those customers get no WhatsApp messages	All customers are reachable
Flows silently skip recipients	Flows reach the full audience

A usable, correctly formatted number is what lets flows, campaigns, and order notifications actually deliver.

Note

Requiring the phone number applies to new orders placed after you change the setting. Existing orders keep whatever contact details they were placed with.
