Since they exclude vowels and BSZ for robustness, they could go through to y (unless counting it as a vowel I suppose) though only needing to apply it to the year component, but no one seems to know for sure. Apple needed to have at least a base-27 (not base-26) number system for this to work, because there are more than just 52 weeks per year. (before the change, 11 digit numbers were computer serials, 12 digit were service part serials, now 12 is computer, and iirc 17 or 18 are part)Īs my notes indicate, I don't know what will happen in 2018. # or will X be skipped and 0 be used for early 2018? # how apple interprets years when it hits 2018 is unclear. # (all years have 52 weeks plus one or two days, so the system must be able to handle 54 weeks) (either starting with the first or 28th week) # the week code is the number of weeks offset from the year. # the year starts in early 2005 with 0, 1 is late 2005, 2 is early 2006, M is early 2014, etc # the number notably does not include vowels AEIOU, and consonants BSYZ # apple is using a "base-27" numbering system for year and week, the digits are: 123456789CDFGHJKLMNPQRTVWX # week is two digits, 00 through 51, week of year repeats every 10 years, "4" could be 1994 or 2004 etc Now that you know the model of your device, find the perfect accessories using our Shop by Device tool.So I got that itch again this morning, and actually managed to dig up enough information that I could tease out the full rules for Apple's new serial number format
