Detailed Explanation
The backend validation relies on OCR (Optical Character Recognition). If you type 'Mohd' in the form but your PAN card says 'Mohammed', the system instantly throws Error 100/200.
Pro-Tip: If your local documents have spelling variations that cannot be changed, download the 'UIDAI Standard Certificate for Enrollment/Update'. Get it physically signed and stamped by a Gazetted Officer (Group A/B) or your local MLA/Tehsildar. This bypasses the automated OCR rejection and acts as an ultimate override document.
