* We have two vehicles, both the insurances got chasis/engine no. wrong. I don't know how long it's this way, my guess is right from day one. One of them needs renewal in couple of weeks, when I tried to renew online, I got this message saying that Registration and Chasis are not matching or something along that line. I hope this can be fixed in near by branch.

* RC has initials whereas in Aadhaar my initials are expanded. Because of that I am not able to update mobile number online, and have to go to RTO.

? Driving license too has initials and I would like it to be expanded. Except educational certificates everything else has the initials expanded. Again do I have to go through the whole name change procedure for this or a simple request letter would do?​

? Municipality assigned new door number some time back. Do I have to apply for change of address in driving license for that modification? I mean like simple request letter would do or do I have to go through the whole change of address procedure for this minor modification?

? I couldn't find my DL details online. This is how my DL no. is printed, and the formats are different in front and back.
F/TN/0RR/012345/YYYY This is how it is in front of DL
12345/TN0RR/YYYY This is how it is in back of DL

RR - 2-digit RTO CODE
YYYY - YEAR
Don't know why there is a 0 before RR and don't know what does that F at the start means.

I tried couple of recommended formats and tried couple more. I am just getting "NO DL Details Found...." Following are the formats I tried.

TN-RRYYYY0012345
TN RRYYYY0012345
FTN0RR012345YYYY
12345/TN0RR/YYYY

Do you guys have any idea what I can try now? Do I have to go to RTO for this?​
