Code not valid - The scanned code 100113 could not be applied

Spoublon — Sat, 20 Sep 2025 08:32:50 GMT

So has anyone found an answer to this problem? I have a compatible Honeywell 1250G and I can't get past this message. The scanner is recognized and scans the barcode. It is seeing the correct barcode number, but giving me the message: Code not valid - the scanned code ##### could not be applied. It has the correct number listed and if I search by that number square recognizes it in my inventory. Why is this happening?

Not finding anything helpful in the troubleshooting pages.

What device are you using the Scanner with? What POS system are you using the Scanner with also?

Your question is not letting anyone help you since we do not know if you are using Square POS, Square for Retail or Square for Restaurant? The other thing is there are different settings to look into if you are using a Square Stand, Square Register, Ipad or Android device and also the Terminal.

Now I know when I scan an item that is not Valid, Square asks me if I want to add it to my catalog, So I am not sure why you are getting the code that cannot be applied.

Can you post a picture please of the Screens error message?

If you have the code in the SKU field for the item you should not have an issue. Now if you put that code in as a GTIN it would have an issue since a GTIN has to be at least 8 numeric values and your code is 6.

This is the best I can do until I hear back from you and see an image of you error.

We're having the same problem! We're getting the message using a Zebra (Symbol) DS6707 scanner and a Square Register. Whether we use our typical Code 39 or try transitioning to EAN-13 for the barcode formats, the number is *clearly* communicated to the Register, but the Register doesn't know what to do with it.

We get the following error message:

If we type our 6-digit SKU into the Register manually, it pulls up the item just fine. We would strongly prefer not to transition from the Code 39 barcodes, since we have thousands of items already barcoded in this format.

The Symbol scanner, when connected to the Square Stand, works just fine. It seems like it's only the Register that has such trouble with looking up these SKUs after they're communicated by the scanner.

Any advice would be greatly appreciated! We don't want to have to return the Register and work with the older POS systems unless it's absolutely necessary.

Hello,

The solution for me was to set the actual square terminal back to default settings. I had tried setting the scanner back to default with no luck, but when I set the square terminal back to default and reinstalled the scanner it was working fine.

After setting back to defaults I had to re-sign in and re-setup my wifi, but after that all was fine.

Hope this helps.

@Spoublon ;

I use the Square stands with Zebra DS6878 scanners, my solution came in an update in June of 2023. I have since had no issues with either stand or scanner. My issue was scanner would after a random number of scans just no longer scan. I would then unplug the scanner from the usb hub, plug it back in and it would work. Never had the issue as pictured above about code being invalid. Would get a code not found would you like to create a new item.

What you did by resetting your terminal to defaults is I believe one of Squares trouble shooting steps along with making sure your on the most up to date App and device versions.

Thank you! Actually, our issue had a different solution, and I want to record it here in case other people have the same problem.

We use the DYMO Label software to print our labels with a Dymo printer. When you use the "Import Data and Print" feature to generate bar codes/labels from a spreadsheet, it seems that DYMO Label inserts a space after your data before creating its bar code. So our bar codes would say "12345 " instead of "12345". [For anyone encountering the same issue, just hit Backspace after adding a data field to the Dymo template, and you'll get rid of the space.]

The space after the SKU was actually enough for the Square Register to throw an error message instead of finding the correct product. I wish that Square's software would ignore the whitespace, but DYMO Label shouldn't have put it there in the first place...

Since we already printed thousands of bar codes with these spaces, we're using 123Scan from Zebra (our scanner company) to teach the scanner to ignore the whitespace.

Crazy. But I hope that helps somebody.
