H1 b stamping in India .. H1 approved for 1 year

Hi All,

I am working in US right now and planning to go to India this august 2015. I got H1b approved for 1 year (Oct 2014 to Sep 2015) . I applied from renewal and got it renewed for 1 more yrae (Oct 2015 to Sep 2016). I am not sure which H1B receipt number should I enter in DS 160 form. I have valid H1B till next year but I am going to India in this August(Will be in 1st H1b period).Please advice.

Thank you for any help you can offer.
