 Check if the customer's email is already registered in the store, and if it is, automatically displays the login form.

Customer Exists is a simple module and provides only a few features, but a great help for Magento 1. Using Magento form validation standards, we implement validation shortly after the customer types their email into your store registration page. If there is a registration with the email entered in your store, the login form for your customer will automatically be displayed.

In Magento 2, by default the Luma theme comes with the ability to check if the customer exists just after entering his email in a registry entry, if the customer exists, the login form is displayed. The Customer Exists module proposal is similar to Magento 2 but adapted to the standard Magento 1 (default and RWD) layouts.

Module functionality is present on two pages:

  • /customer/account/create
  • /checkout/onepage


  • Check if a customer exists by email.
  • Shows a popup with the login form if the email is already registered.

If your store works with different routes for checkout, just contact our support:
