Rather than struggling with a bunch of old command-line scripts to calculate the Personal ID (PID) of your shiny new Amazon Kindle, I’ve released a super-freakin’-easy webapp to do it for you in a matter of seconds. No joke.
Simply visit http://kindletools.prestonlee.com, follow the instructions, and be sure to gift me a short novel to say “thanks”. 
Update: See Jer’s post on the bigger process of converting Kindle books.
Ok I have two Kindle 1′s. I got the PID from one no problem. From the other no joy. It says the # is not valid even though I verified it several times and paid attention to the case!
Any ideas why?
Thanks
The most likely issue is something like mistaking a “0″ (zero) for “O” (captial letter ‘o’), or a similar mistake. If you’re absolutely sure you have it correct, shoot me your serial number via email and I’ll try to figure it out.
Also note that I do *not* own that particular model, so I don’t have a way to test for older generations. Iy you aren’t planning on using it otherwise, please consider donating it to the project…
To Admin:
Can you give me an email I can send the SN to?
Thanks
(Sent via email.)
it doesn’t seem to work for me. I have all capital letters and I’m sure it’s the number 0 instead of O. Any advice?
The tool didn’t work, or the PID it gave you didn’t work?
Thanks for the good work. However the calculation of the kindle PID did not work for my serial number. The serial for my kindle DX starts with a B005…
Please can you assist?
Will be so grateful
This does happen periodically. If you could privately send me a little more information about the device I’d be happy to take a look at it. (Serial, model, country, approximate purchase date, anything else that might be unusual about the device.)
Hi, I do not have the Kindle but I do have the iPhone version. Would you please tell me where can I get the “40-character number for the Kindle iPhone application”. Thanks a lot!
Curious as to if you ever cracked the B005 Kindle DX issue. I tried to play around with python script but fear I am not that good at it.
It should be trivial to do, but I’ll need to work with you to figure it out. I’ll email you directly.
@Chris
Honestly I’m not sure since I don’t have that application. Please post instruction when you figure it out, though, and I’ll add it to the Kindle Tools site!
@Lone
Please try it again. The site was just upgraded to support a few new serial number types.
I am also having a difficulty getting kindlepid.py to give me a PID and it may be because of the zero’s or capital “o”‘s in my serial number. I am hoping you can help me understand what my serial number is. It is on a Kindle 2 that was bought in the United States in approximatly Sept. or Oct. of 2009. The serial number is B003A0A094160289, here I used all zero’s to give you the serial number, but any or all of them may be wrong. I have looked at the ’411′ screen of “settings” and at the printing on the back of the Kindle below the logos and the model number. The model number by the way says “D00701″

I’m having a similar issue with an international Kindle2 from December 2009. My s/n also starts with B003. Fire me an email if you’d like more information.
Definitely. I’ll shoot you an email. Should have a site update out soon. Hold tight..
