Explain Fiscal Year from Petition Number

Hi,

I want to know that if my Petition Receipt Notice (I797 receipt notice) Number, filed on April 16th, 2012 is:

EAC-12-143-50112.

Could you clarify:

  1. If that was filed for fiscal year 2012 or or 2013?

  2. Because the H1B quota for fiscal year 2012 was reached in November 2011, it cannot be for FY 2012. And if it is for FY 2013, for which they started accepting the petitions from 2nd April, 2012 (1st April being Sunday) then the number should begin with the same fiscal year ieEAC 13 instead of EAC 12.

Please clarify the confusion.

THIS PETITION WAS FILED IN 2012 FY 2013.
