Where to find factory list in apple serial number

In apple products serial number, the first three is "Factory and machine ID", for example, c3 means China, where I can find the whole factory and code comparison table?

Interesting question - a quick search didn't turn up much, but there's a site you can do lookups on: http://www.chipmunk.nl/klantenservice/applemodel.html and a macrumours forum where a few people have posted their info..

Here's a list of factories mentioned in the forum above (plus mine):

• Factory: DL (China - Foxconn)
• Factory: DM (China - Foxconn)
• Factory: DN (China, Chengdu - Foxconn)
• Factory: C0 (Quanta Computer (Susidiary = Tech Com))

Another site offers lookups, too, but didn't have info for my 2013 MBP: http://www.appleserialnumberinfo.com. They have some interesting but unrevealing javascript validation for their lookup form..

There is an image attached in this forum post which explains a few more details:

The image was a screenshot taken before Apple asked the site to remove the original article.
