I have figured out how to identify the production date and place based on the serial number, found on the box. The S/N inside the phone doesn't have to do anything with the one, printed on the box! Also, don't mix SN with IMEI.

Production date is encoded in the first 3 positions (reading from left to right):
1st position defines YEAR: 0 - 2010, 1 - 2011, 2 - 2012, 3 - 2013 and so on
2rd and 3rd define MONTH: 01 - January, 02 - February, 03 - March, 04 - April, 05 - May, 06 - June, 07 - July, 08 - August, 09 - September, 10 - October, 11 - November, 12 - December

4th position defines county:
K - Korea, C - China, B - Brazil.

For example:
211KPBF****** (last 6 digits are hidden for privacy reasons):

So, 211 - 2012 November (11), K - Korea.

Hope, this helps!

P.S. Last 6 numbers of the serial number match the last 6 numbers of the IMEI. It is incremented by 1 with each newly produced unit.

I'm located in the south east United States. I was thinking that it seemed pretty quick from production to end user distribution aswell.

I had my C2 (which is February 2012) Galaxy Nexus produced and shipped to my country before February 10 - the day, when I bought it.
So, ten days is absolutely normal for the well organized logistics to deliver the product from the factory to the end-customer.

    I did some sampling on the LG database.
    Retrieved some 1% of the data up from the 100000 mark.
    Found some interesting things like holes in the sequence, date order not in line with imei order, list of buyers, etc.
    Check my spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0AqPPcfoSlaB_dEVFcnJUTnljaC1LcjVWR2RIa2pQT3c

    Can anyone post and match there details here?

    Very cool!

    It gives us means to find out the production rate.

    So, they did produce at least 70K devices in October, 90K in November and 210K in December, still counting (just 16G devices).

    Not bad, now as christmas orders are completed google and LG are really ramping up the production.

    A
    HK - Hong Kong -> where it is bought
    GB - Global?
    K - Korea -> where it is made

    GB seems to decode as follows:
    G - 16Gb (8 - 8Gb)
    B- Black.
    8
    Ladies and gentlemen, we have just reached the millionth device!

    (of course just judging by serial number, i.e. minus gaps)

    ATURBK 302KPSL999998 20130205 TURKEY

    Which means, IMEI prefix 35391805* is now officially complete and the next one will be started.
