Name at ticket (Length issue/problem)
IRCTC (Indian Railway Catering and Tourism Corporation ltd) allows only 16 characters for the name of passengers so how you can overcome with this problem in case your name have more than 16 characters.
There is no solution to increase the character limit for the name of passengers while booking the tickets through IRCTC.
However you can use abbreviations...
more... for your name such as Ravi P Shukla instead of Ravi Prakash Shukla.
You can as well skip the middle name and use it as Ravi Shukla instead of Ravi Prakash Shukla.
But when you do so, make sure to provide the ID card number in the IRCTC website while booking the ticket so that you won’t face any issues while travelling.
