HI,

I am trying to add some additional fields in the native Shopify signup form. Currently my form is as below:

I want to add an additional Phone field to this form and store its information and display in Admin Panel-> Customers Detail (below).

I tried to do it through code and template but its not working as expected. It does show the field but on submit the information is not stored properly. I added the below code in customer-account template.

Please note that I am using the Prestige theme for my site.

Any help would be appreciated.

Thanks in advance!

Hello diananh

If you’re looking to add extra fields like a Phone Number to the Shopify registration form and have that data saved correctly in the Admin > Customers section, then using code alone can sometimes be limiting, especially with themes like Prestige where form handling is tightly integrated.

To solve this more reliably, I recommend using a Shopify Customer Registration Form App. This app allows you to:

  • Easily add custom fields like phone numbers, company names, tax IDs, and more—no coding required
  • Ensure all submitted data is properly stored and viewable in the customer detail section
