Hi,

TNEA stands for Tamil Nadu Engineering Admission is a state level entrance test for Tamil Nadu colleges.

As you have mentioned you forgot to mention your permanent register number (assuming your permanent mobile number), is not all a issue. I suggest you to wait for correction window to open, there you will be able to edit your mistakes along with updation or changes needed in documents uploaded. Please check the website on regular basis, and don't miss the opportunity. No changes requests are entertained after the correction period is over.

I hope it covers your query.

Thank you!
