You can check IRCTC PNR Status through SMS. All you have to do is, text your PNR number on a 3-digit number given by IRCTC i.e.‘139’. Make sure you don’t leave any space between the numbers.
For example: Text PNR 10-digit PNR number i.e. PNR 1234567890.
Also, you have another option to send the same SMS to 5676747 to get your PNR train status. However, it would charge you Rs.3 per message. But yes, in case you have not received your PNR train status by sending a message to 139 for any reason, then you can try this one.
Once you are done with your SMS, you will receive the updated PNR details in your inbox.
