Decode The Meaning Behind Your Apple Serial Number

All Articles Featured Discussion

The serial numbers of Apple products contain a codified language that can give you information about your Apple device that can’t be found through any other means—everything from the location where it was manufactured, the date it was manufactured, and much more. This information can be valuable for troubleshooting issues with your device or just for curiosity’s sake. So let’s get to breaking down their impenetrable code.

The most straight forward way to decode your serial number is to type it in to an online service. Your Apple device’s serial number can be found either in the device’s settings menu or printed on the device. One online service can be found on Apple’s official website, and can help you determine the model of your device, whether it has a valid purchase date, and whether it’s still covered by Apple’s technical support. Apple’s own serial number lookup barely scratches the surface though, leaving most of the info it contains out of their results.

The Apple Serial Number Search tool developed by the cryptanalysts here at Beetstech can help you to uncover a whole lot more info about your Apple device. This tool not only lets you look up Apple devices by serial number, but it returns all compatible parts, and even allows searching by other criteria like EMC number, model identifier, and model number. Additionally, this tool lets you find Apple parts by searching the Apple Part Number, a part number printed on the component, or any combination of keywords you can think of.

But today we’re breaking it down the old fashioned way, and while not everything can be determined through this method, the serial numbers of Apple products follow a structure that allows you to figure out some information with the naked eye. Apple devices manufactured after 2010 generally have 12-character alphanumeric serial numbers, with the first three digits representing the manufacturing location, the following two indicating the year and week of manufacture, the next three digits providing a unique identifier, and the last four digits representing the model number.

Each manufacturing location is represented at the start of the serial number by a different alphanumeric code. Apple manufactures their devices in a variety of locations, and unfortunately not not all location codes are known, but the following is a mostly complete list of codes and their corresponding factories:

Apple Facility of Manufacture Codes
Code Factory
FC Fountain Colorado, USA
F Fremont, California, USA
RN Mexico
CK Cork, Ireland
VM Foxconn, Pardubice, Czech Republic
SG, E Singapore
MB Malaysia
PT, CY Korea
EE, QT, UV Taiwan
FK, F1, F2 Foxconn – Zhengzhou, China
W8 Shanghai China
DL, DM Foxconn – China
DN Foxconn, Chengdu, China
YM, 7J Hon Hai/Foxconn, China
1C, 4H, WQ, F7 China
C0 Tech Com – Quanta Computer Subsidiary, China
C3 Foxxcon, Shenzhen, China
C7 Pentragon, Changhai, China
RM Refurbished/remanufactured

The year and week of manufacture are also represented by an alphanumeric code which is, fortunately, easier to decipher. The fourth character of the serial number represents both the year the device was manufactured in, and whether the device was manufactured in the first or second half of the year. The following table shows how to interpret the fourth character:

Apple Date of Manufacture Codes
Code Release
C 2010 (1st half)
D 2010 (2nd half)
F 2011 (1st half)
G 2011 (2nd half)
H 2012 (1st half)
J 2012 (2nd half)
K 2013 (1st half)
L 2013 (2nd half)
M 2014 (1st half)
N 2014 (2nd half)
P 2015 (1st half)
Q 2015 (2nd half)
R 2016 (1st half)
S 2016 (2nd half)
T 2017 (1st half)
V 2017 (2nd half)
W 2018 (1st half)
X 2018 (2nd half)
Y 2019 (1st half)
Z 2019 (2nd half)

The fifth character represent the week in which the device was manufactured. There are 28 possible characters in this spot: the digits 1-9 are used to represent the first through ninth weeks, and the characters C through Y, excluding the vowels A, E, I, O, and U, and the letter S, represent the tenth through twenty-seventh weeks. For devices manufactured in the second half of the year, add 26 to the number represented by the fifth character of the serial number. For example, a product with a serial number whose fourth and fifth digits are “JH” was manufactured in the 40th week of 2012.

The next three digits are an identifier code which serves to differentiate each Apple device of the same model which is manufactured in the same location and during the same week of the same year, ensuring that each device has a different serial number. Finally, the last four digits of the serial number represent the product’s model.

The serial numbers for iPhones additionally contain information about the device’s color and storage capacity. For iPhones manufactured after 2010, this information is coded in the final four digits of the serial number; the ninth, tenth, and eleventh characters represent the iPhone’s model and color, and the final character represents the iPhone’s storage capacity.

Decoding the serial numbers of Apple products can be useful for a number of reasons. If you are interested in repairing your device yourself, determining which factory the device was manufactured in, or the date of manufacture, can help you to determine which replacement parts must be ordered to fix the device. Additionally, understanding the serial number structure can help you to troubleshoot issues with your device, as known issues can arise on products manufactured in certain factories or on certain dates.

Quick question: Counting all the letters you mention in the alphabet (C, D, F, G, H, J, K, L, M, N, P, Q, R, T, U, V, W, X, Y) plus the number 1-9 you have 28 characters, not 27 as you say.

More so, you say that to obtain the second half you add 26 to the number: this would make the first week of the second half week 27 -the same week is also identified as the last week of the first half, if you account for 27 symbols.

Could you clarify this discrepancy in you, otherwise excellent explanation?



Thank You! Very interesting and valuable for those of us who be pre-loved macs like my 2 17″ mbpros!


Thanks, I was looking for a comprehensive guide to decoding the serial number myself instead of sending them off to who knows where on one of the sites that decodes them for you. C02HC = week 10 of 2012, which makes sense for my Mid 2011 iMac. D25RL = week 17 of 2016, which also makes sense for my Late 2015 5K iMac, though I don’t see D2 listed as a manufacturer code.

Thanks a lot for this! Really useful.
I needed to find out the age of the devices we currently have in our iOS estate to swap out anything older than 4 years and this was the easiest method.


Should ‘Z’ be 2019 in the year of manufacture?


Thank you for a very helpful article! However “The number of models of Apple products is too large to list each one’s corresponding code in this article, but the corresponding models for the last four digits of each serial number can easily be found online.” Can you provide any help with this if you know anything? Because I couldn’t find this info online. Thank you!


I found a lot of them had ME,MB, ML, MP,


I found a lot of MacBook pros beginning with ME,ML, MC MP, MGMR whole MB is the only one listed. What am I missing


Let me answer my own question: the combinations of M…is the order # not the seriel #


My iphone x Start with GHKXE****CL8 Now can please help me find out the manufacturing date .


My ipad has no numbers… all capital letters that start like this…. GCGVT

Wow! thanks Cody Henderson!

Thanks a lot for this valuable tool to acquire information regarding our various apple devices. In my case, I was issued a replacement which is en-route from China and I wanted to purchase a case and glass for the new iPad. The manufacturers made a distinction as to compatibility with buttons and lenses of their cases based on the years produced. Took a day trying to find this info, then I found your great bit of research…..Cudos brother!


Would u be kind and decoding my nr iPad air serial no: F9FZK51SLMPD


Difference between DNT & FF in serial number


Thank you for this invaluable information

Jimmy Siles

Thanks for the valuable insight!

Rover Spotts

Can you explain how the production number works? For example, it seems that 3AZ works out to 577 (the 577th unit that week). How does this math work?


the manufacture year doesnt seem to work… i have a brand new iphone 12 pro max, and it says that it was manufactured in 2011


Thank you for the information Cody


Can you tell me some Information about this iPad? MYFR2FD/A


Kevin Zebroski

I don’t think the serial date codes kept with the same idea, unless Apple has a fiscal year that they go by – I have a pair of AirPods Pro that has a date code of DF, that would be the second half of 2021, but I bought them in mid May…


Hello, a lot of websites say the first digit of an iPhone serial number shows if it is refurbished or not. My iPhone 12 Pro starts with F17. So is it refurbished or just made at Foxcon? Thanks


Thank you. That information was so helpful locating when my MacBook Pro was made. I couldn’t remember when I bought it!

Erm it says my phone was made in 2010 but it came out in 2016…


Hey there dear Cody… Can you kindly help to understand a 10 character Apple iPad Serial number? Thanks in advance..


Hey Cody
Is it the same calculation with iOS 17 and above or on new models like the iPhone 14\15?
For example, the fourth character in my serial number is the number 7.
Thanks 🙂
