Hi guys,
There is a toll free helpline given in Incometax India Website.
1800 180 1961
Works between 9AM to 6PM.
Anyone can try tomorrow and tell if you get any info.
There is also an email id
webmanager@incometax.gov.in
I have sent an email asking clarification.
P.S. Dont know how knowledgeable guys in that dept are, because they wouldnt accept my passport as relevant ID card for reissuing PAN card because they say my name in it is in reverse (fathers name first 
)
Common sense say PAN is sufficient, My tax consultant also says the same… but… hehe! 
While doing internet search, the blogs and discussions made by Indians who make similar earnings from USA doesn’t seems to settle with PAN number for their case. Lot of old discussions made few years back mostly revolves around how to get ITIN or EIN. May be right now with Envato’s case, the requirements possibly relaxed to foreign tax ID. hmm…

Can AADHAR be alternative? 
Aadhaar Card is not required.
If you have no passport then you may send original Driving License and Voter Card to IRS Certified Acceptance Agent’s office(in India).
New Update:
I’ve been playing with the Tax forms recently. and found that when changing country, There’s a box below containing tax treaty info also changing. That means, envato is calculating % based on the country. There’s no tool available for envato to check whether a Tax ID is valid or not.
So, It’s not a problem if you put your identity card or your mobile number (Ofcouse you can enter PAN card also) Envato will deduct only 15% if India is chosen.
Shhhhh… don’t tell envato about this
Can AADHAR be alternative?
AADHAR loll…!!``
Choose Pakistan as your country and get
The beneficial owner is claiming the provisions of Article 8(1) of the treaty identified above to claim a 0% rate of withholding.

India is larger in terms of economy compared to these countries.
@natmanSo if I'm not wrong, for now we can fill the form with PAN, as getting other number well within time is nearly impossible.You have until January 1st, 2016 to fill out the form, however, we
encourage all authors to complete their form as soon as possible to make
they’re ready well ahead of the deadline and avoid any unnecessary
withholding. Starting early is particularly important if you don’t have a
Foreign Tax ID and need to apply for an ITIN - the IRS estimates the
application process can take between 4 and 6 weeks. If you are concerned
you may miss the deadline, you should complete a W-8 form with whatever
information you have, and then resubmit a fresh one when you have an
ITIN (to prevent the US presumption rule kicking in and Backup
Withholding applying).
After January 1st, authors who have not completed a W-8 form will be
presumed to be a US author who has not completed a form, and we will
apply Backup Withholding tax of 28% on all sales. We will remit this tax
to the IRS frequently, and once it’s gone, you will need to take it up
with the IRS, and we won’t be able to assist much.
Checking out procedure for passport. At least it is considered as one of the docs for passport application
