![]() (The letters 'O' and 'I' were not used, presumably to avoid confusion with the numbers zero and one.) If we assume Apple began each week at 000, this identifier becomes an ordinal indicating the model's production order that week. The next three characters are a three-digit base-34 unique identifier. In our example, we see that the Mac with serial number F4 41 2SAM0001 was made in the 41st week of the year. ![]() The next two digits indicate the week of the year of production. In 19, a number of Macs were made at Fremont with "F1" or "F3" as the factory designator, and modern build-to-order Macs may have a number preceding the letter in the factory code. Referring back to our example again, we see that the Mac with serial number F 4 412SAM0001 was made in 198 4. In all cases prior to the Mac Plus, this will be in the 1980s. The first numerical character* indicates the last digit of the year of production. In our example serial number, F 4412SAM0001, we see that the Mac in question was made in Fremont, California. The prefix consists of one or two letters (and/or numbers) designating a factory code: The methodology behind this decoder is reasonably simple. WARNING: Geek alert!
