Product SKU Number Breakdown

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

E = US manufactured for export (green label)
F = Federal agency – non-military (red label on the ones I’ve seen)
G = Rebuilds FET IN (orange label)
M = Military
P = AU manufactured
U = US manufactured for domestic/Canada

Known anomalies are:

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

Prefix 2 – PI2350202T

2 = SF ES 1913 Rail Military
3 = SF 1913 Rail Military
4 = ES 1913 Rail Military
5 = 1913 Rail Military

Pistol Model – PI2350202T

These are just the numbers in the model of the pistol. A Glock 17 would be ’17’, as would a 17C, 17TB, 17R, 17P, 17T, 17L, etc. Known anomalies to this logic are:

10 = 19T
12 = 17R

Unique Identifier – PI2350202T (I have seen a pistol that had multiple unique identifiers. 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.

  1. Great information. Thank you for all of your research. Most all of my question about my Glocks you’ve answered.

  2. Thanks! Can i send you a picture of the label? It doesn’t have the sku info on the right hand side. It is a tupperware box with a gen 3 Glock 27.

    1. What model? Only the two 43X and 48 slimline models have factory silver slides. Anything else has an aftermarket finish, including those with NIBX finish.

  3. I would really want to know what generation my Glock 21SF is. I recently bought a second hand Glock with a purple tag. SKU: G21SF13AUT. I am really interested in learning what generation my gun is. Thank you.

  4. I recently bought a green framed G45 advertised as an “elite tactical coating” variant. Distributor cerakote? ETCPA455S204PB.

    1. Well, can’t say who coated it, but “elite tactical coating” isn’t used by Glock. And that SKU number isn’t a Glock SKU.

  5. Great information here, can you help me identify this Glock that i just acquired, I am now familiar about the blue label information that you have her but not much more. How can I send you attachments for help if possible……Thank you in advance


    1. TBF = Tactical Brown Frame

      It says “TBR” at the end of the SKU on the box I have.

      What the R stands for, I haven’t a clue. It’s also searchable on Google under the TBR designation (ads for the model come up), but not the one you have listed for this option.

      Searching with “TBF” only has results to this site.

  6. This is the best listing of this information I’ve seen on the net! Thank you! This really helps me choose which firearm to buy, based upon the SKU.

    Do you update this page as you find more SKUs?

    Thanks again!

    1. As I get new information, I try to keep this up to date. I have a spreadsheet with about 800 different SKUs to draw info from. And things get added to that often.

  7. My number GLPI1750204BWF.
    Following your study it all makes sense except the BWF.
    Thanks for your research and I appreciate the work you have done.

    1. GLPI1750204BWF isn’t a Glock factory SKU. Glock SKUs don’t start with ‘GL’. Those are usually created by distributors. That being the case, ‘BWF’ would also be added outside of Glock.

  8. Is it common for Glock Manufacturing to mislabeled Blue Labels for Red and vice versa? I have used your cipher key and have a Blue Label but Glock says it’s a Commercial gun.

  9. I have a purple label 19x I just purchased, and none of the sku breakdown adds up. Any info on those? Thanks!

    1. Can you list the details from the label? I’ll see if I can figure it out. The purple label format can be weird sometimes.

  10. I have a Glock 48 I purchased and am curious because I just got it back from evidence is it common for the skew sticker on the box to have a blue one under a white one with all matching identies except the last3 digits under the skew bar difer from752 on the blue one and745 on the white label and above this q bar the white label reads p a 48 5 sl 701 the blue one reads PA 485 sl702 and the white one is perfectly placed over the blue one just wondering if this is how they come or has my property been altered in some way?

  11. Also, forgot to mention it’s “Tactical Bronze”, as opposed to brown, under that designation (TBR)

    1. Yep – Glock deviated from the norm and uses the “MA” as the generation instead of a single digit. UMA195S203MOS for the red label, swap the 3 for a 2 for the blue label, etc.

  12. Any info on a 17m mos sku? I just got a pow rebuild but can’t match up anything after the trigger weight in the breakdown. Thanks!

  13. I have three factory new G17 Gen5 MOS guns, each box has the contract overrun purple label, but the SKU suffix is, “AUT”. Can you tell me what this suffix indicates? Thank you!

    1. That usually just means they were made in Austria, and probably not originally destined for the US.

  14. I’m going to buy a Glock 30 but I’m seeing several UPCs and am wondering what is the difference.

    UPC 764503912894

    UPC 764503912863

    UPC 764503032011
    MPN PF3050201?

    1. The one on the bottom is the normal SKU (MPN) I would expect to see in the states for an Austrian made 30SF. Hard to tell with the other two, and that format of SKU can’t be broken down the same way.
