    Some fantastic research conducted by J Huff at http://www.learnallthethings.net/blog/2017/3/1/facebook-origins

    What we see in December 2009, between the 8th and the 12th, the Facebook ID numbers changed from a 10 digit format to a 15 digit format. Based on the dates having overlap in the month of December 2009 with both 10 and 15 digit numbers we can’t determine a clean transition date. We can make one major assumption from this data. An account with a 15 digit ID number can NOT be older than December 2009
