Require phone numbers for PayPal Express Checkout orders
If you depend on having your customers' contact information and use PayPal Express, then you might have noticed that the Shopify order details page does not contain the phone number.
Log in to your PayPal account at paypal.com.
Click My Account.
Click My selling tools:
In Selling online > Website preferences, click Update.
In Contact Telephone Number, choose an option for Contact Telephone:
- On (Optional Field) - adds the phone number field to your checkout but it is not required for checking out.
- On (Required Field) - requires that your customer enter their phone number when checking out.
Requiring a phone number on checkout usually decreases conversions and sales. Many people don't like to give out contact information. Unless you absolutely need the phone number, you should choose On (Optional Field).
