@ Mr Deepak Gupta
Your answer is wrong. Perhaps you could not pick up the question correctly. Whatsoever you have informed is correct but have not relevant to question. You have mentioned eight digit number as Receipt Number which we get on e-filling Qtrly TDS Return.
@ Mr Manal Kumar
Your answer is wrong as you also failed to understand the question exactly. However, you are right that this No. is displayed at right top.
@ Mr Ram Kumar Goel
You are correct.
@ Mr Vijay Kumar.
Already said Mr Ram Kumar Goel has answered correctly. Whenever we request for, quarter wise, Form 16A (mandatory for Companies and Banks but others can also request. Form 16 is also on request but not mandatory) from NSDL site by logging into our account then system generates Form 16A and emailed at given email address. And Form 16A thus received carries its Number at right top. To open and print Form 16 requires some skills.
