The Customer Pending Registration Magento extension allows store owners to review customer information before allowing new customers to log in. It maintains the normal registration process but places new accounts in a pending status until approved by an admin, preventing dummy information. Admins are notified of new registrations and must approve pending accounts before customers can access the store.

Customer Pending Registration extension improves Magento registration process. With this extension, you can review customer information
before allowing them to log in your store.
 Sometimes, customers always try to provide dummy information for their account in registration process to make the
registration faster. Except you need their exact information for tracking or a report. So a process which reviews customer
information before allowing them to log in your store might be helpful. And you can do it easily with our module: Customer
Pending Registration..
When the module is enabled, customer registration process is working normally, but customers cannot log in your store
immediately. Instead of that, they get a message about their "Pending" status. You will also receive a notification email when a
new account is created. Once you approve that account from the backend, customers can log in.
