Dear Hima, you dont get any code notification to your Registered Email and Phone number. You need to login to the official website with your login credentials. Go to 'My Account' and click on 'Dashboard'. Click on the link provided and that generates a code for you. This code will further be useful for the next steps like filling your Qualification Details, Address details, making a payment and selecting your exam city. After all these steps, click on 'Submit' and take a print out of the page.
