If you've lost your college application registration number, don't worry, there are several ways to retrieve it. First, check your email inbox and phone messages for a confirmation email or SMS you likely received after submitting your form. You can also log into the university or college's online portal using the credentials you created, as your registration number is likely listed on your profile or academic records.

If these steps are unsuccessful, contact the college's administration or admission department directly, providing your name, date of birth, and course details, and they can help you recover it.

Additionally, checking your admission letter, fee receipts, or asking classmates who applied at the same time might also reveal your registration number. If all else fails, visiting the university registrar's office with valid ID proof can be the ultimate solution.
