When we used GS1QRCode to build a label, it will show “invalid barcode data” with “0136972530697928112506261727062610792005F262193792105F26C011”. we try change the barcode data length to 54 of “0136972530697928112506261727062610792005F262193792105F”, it’s ok.
What’s the limit for GS1QRCode?

Hi Michael,
>> What’s the limit for GS1DataMatrix ?
We tested GS1DataMatrix with various lengths and could observe that it can hold characters up to a maximum length of 54 characters. Please let us know if you need any help with this.

Thanks, Can you generate a correct GS1 DM with 0136972530697928112506261727062610792005F262193792105F26C011? We always get the wrong message ‘invalid barcode data’.

You can see my screen as below.

Hi Michael,
As per our observation, you cannot display a GS1DataMatrix with content having greater than 54 characters, therefore, we have escalated this case to our development team (Internal ID: AR-35934) to get their insights on this issue if any resolution/workaround is possible and will let you know as soon as we have any updates regarding the same.

Hi Michael,
Our development team has notified that your value is good for DataMatrix, but fails to satisfy the guidelines for GS1 DataMatrix, which is why it gets an invalid barcode error.
To test if your value passes as a GS1 DataMatrix, we’ll recommend trying your value in an online tool such as Aspose:
Notice how your value passes in DataMatrix but fails in GS1 DataMatrix.

Anand

Hello Michael,
We too can observe the issue at our end and discussing it further with the development team.
We will get back to you as soon as we get the update from the developers.

Hello Michael,
As per the latest updates from our development team, this appears to be a bug and is currently on their to-do list. However, there is no ETA for a fix at this moment.
In the meantime, they have suggested a workaround: using a plain DataMatrix barcode with FNC1 represented at the beginning. Please find the updated barcode data below:
\n0136972530692411112506261727062610238005626\x1D2193238105626A031
Kindly let us know if this workaround resolves the issue for you.
If not, we would appreciate it if you could share more details about your use case for requiring a GS1 DataMatrix QR specifically, so we can explore alternative solutions or escalate accordingly.
Best regards,
Prabhat Sharma

Hello Sharma, it still not working for our project requirement, where can set the FNC1 code?

Hello Michael,
We are discussing this with the development team and will get back to you with the updates soon.
In AR you can use new line symbol as FNC1 so we updated the barcode data in the last post as per this specifications.

Hello Michael,
Please see the following data for the barcode and let us know if it works for you:
=ToChar(10) & "0136972530692411112506261727062610238005626"&ToChar(29)&"2193238105626A031"
The developers are working on the issue and we will update you as soon as we get any information from their end.

Hello,
As per the development team, the problem is caused by Application Identifier (AI) 10. This AI represents data of varying lengths, from 1 to 20 symbols. Since we cannot automatically recognize when the data represented by this AI ends, the FNC1 symbol must be added to mark the end of the data.
In AR, you can use the FNC1 symbol (0x1D) or the line break symbol (0x0A, or “\n”) to separate AIs of different lengths and generate a barcode that matches the GS1 format. So, to fix the problem, simply add a line break or FNC1 symbol right after the AI 10 data block, like this:
Using line break:
0136972530697928112506261727062610792005F26
2193792105F26C011
sing FNC1: =“0136972530697928112506261727062610792005F26” & ToChar(29) & “2193792105F26C011”

Prabhat Sharma.
