Here is a breakdown of the product/SKU numbers found in the upper right corner of the case label. These only appear on pistol cases seen in the U.S., regardless of where they were manufactured. Label formats are different outside the U.S. There are plenty of deviations from this list from Glock, which should be no big surprise. I’ve documented over 500 625 800 900 different SKUs just since Glock went to this format with the Gen 3 guns. Note that this is constantly evolving, and I see some new info pop up all of the time. If you have a label that has characters other than what is listed here, let me know. I’d love to see a case label and info so I can investigate. For more information on the different case label colors and what they mean, see Case Label Colors – What Do They Mean?
Note that it’s common to see SKUs listed that start with ‘GL’. That is a prefix that distributors like Lipseys add for internal use. The ‘GL’ is not part of the true Glock SKU number. Below each SKU is a UPC that correlates to the SKU. The UPC almost always starts with 764503 for true Glock SKUs.
In the sections below, I break down the various characters, using the example SKU of PI2350202T. The bold items are the most common ones.
Prefix 1 – PI2350202T

F = Federal agency – non-military (red label on the ones I’ve seen)

Known anomalies are:
- The U.S.-manufactured Gen 4 17T, with a SKU of PG1050202, which would indicate Austrian manufacture.
- The U.S.-manufactured Gen 5 G45 MOS 7 with Acro P2 optic, with a SKU of PA455S303MOS7A1, would indicate Austrian manufacture.

The military MK27 MOD 1 has a ‘MOSU’ identifier), and some of the variations on the G45 include MOSTB, MOSTBDE, and MOSTBGF, among others. For those that indicate a color, that is based on the 8 factory colors that Glock makes frames in. See my post at Glock Factory Colors and Finishes vs. Aftermarket for more info.

UPDATE: By the way – I wrote a quick Excel calculator to break down an entered product SKU. Just enter your SKU in the colored field and hit ENTER. The spreadsheet does use macros, but only for the functionality of the buttons. Download it here.
NOTE: This spreadsheet doesn’t take into account some of the anomalies or recent changes listed above.
Different Style Labels Outside of America
For pistols made outside of the U.S. that are not destined for the States, Glock uses an entirely different label format and SKU. The SKU number appears to just be a 4 or 5-digit number.
Shooters in the United States have often noticed that the label on the Glock pistol case comes in different colors. Why? Well, with everything Glock, there’s a reason. Let’s dive into the meaning of the various colors.
