    I have 2 Pre 3s. The IMEI on both is in the form 012824000XXXXXX. One has XXXXXX = XX4XXX, whereas the other has XXXXXX = X7XXXX. Suggests that at least 70K of these were made. Anyone have different serial numbers (higher, lower or with a different starting nine digits)? And, how predictive is this of the number of units made?

    Usualy first 6 digits are TAC and the following 2 are FAC, which are than followed by 6 digit serial number and last digit is Luhn Check algorithm, which determines the final digit in an IMEI number, I am not sure for USA AT&T one, but if they use IMEI than it should be the same

    European Pre 3 has TAC 355825 and FAC 04.

    As it seems from your post HP Pre 3 from AT&T have
    TAC 012824, FAC 00 followed by serial 6 digit 0XX4XX and Luhn Check algorithm X
    TAC 012824, FAC 00 serial 0X7XXX Lun X

    - If looking this number TAC(012824) FAC(00) SN(0XX4XX) LUHN(X) than 0XX4XX would mean XX4XX pcs if the two digits preceding nr. 4 the ones you marked as XX would be different than 0, than the maximum would be 99.999 pcs, if the two digits preceding nr. 4 the ones you marked as XX would be 0, than the number of produced units would be maxium 999 pcs

    - If looking this number TAC(012824) FAC(00) SN(0X7XXX) LUHN(X) than 0X7XXX would mean X7XXX pcs
    if the digit preceding nr. 7 the one you marked as X would be different than 0, than the maximum would be 9.999 pcs, if the digit preceding nr. 7 the one you marked as X would be 0, than the number of produced units would be maxium 9.999 pcs

    If you let me know the correct first digits I am talking about than I would know for sure (0XX4XX, 0X7XXX)
