I'm pretty sure that same shotcode can be seen throughout the game. I don't think it's anything special. You can find these on the Red Containers that blow up, and on their passive blue twins.
I found this one on Winter Contingency, near the data that you first find.
Edit: Found this On Nightfall, It's better quality:
But I found a new one, That is different! I will get screenshots soon! This is very intriguing!
I also found lots of different variations, and a brand new Shotcode!
Edit: Attached is the grid matched up to the higher quality code.
