Hello

These steps are to be followed to register in ICAI

1. New student means students who has never applied for any course in ICAI, and never ever received Student Registration Number starting with NRO/SRO/ERO/WRO/CRO
New students can only apply for Foundation Course and Intermediate through Direct Entry route
2. Existing student means student who has applied for any course in ICAI, and have received Student Registration Number starting with NRO/SRO/ERO/WRO/CRO
3. Existing users will be verified by their Student Registration Number starting with NRO/SRO/ERO/WRO/CRO and birth date.
4. Use your own email id and mobile number, future communication related to this portal will happen on them only.
5. Once registered an OTP (one time password) will be sent on your registered email id/mobile number. Enter this detail in User verification screen.
6. Once registered, you will be allowed to apply for various courses.
7. If OTP not received immediately then do not panic, it may receive after some time.
After some time,you need to login again with your registered emailid and password. 
Once verified you will be diverted to OTP verification screen, now enter received OTP and submit.
If not received then click "Resend New OTP" button, a new OTP will be sent on your registered emailid/mobile number
8. In your dashboard, list of application form which you have applied will be displayed with status and form acknowledgement number. 
If you click on the acknowledgement number, the form submitted by you will be displayed (of which you can take printout and submit to ICAI Regional Office)
9. If you recieve error Maximum length Exceeded then please upload images of smaller size(kb)

After which you are supposed to pay the fee. After you fill the form you would get an application reference number on your email id or your registered mobile number. You have to continue with the rest of the registration process using this application number. After succesful registration and fee payment you would get your application number (not application reference number). which youwould have to use at the time of admit card release. All the best.
