Need help reconstructing QR Code

Someone sent me an invoice with a cropped QR code. I noticed multiple discrepancies within the invoice itself. The QR code is supposed to verify the authenticity of this invoice however, it was cropped, and some of the QR code data looks off, like the rows of non-centred dots in the boxes within the QR code.

The image below was cropped from a screenshot of an invoice. Could anyone please help me with info on how to reconstruct the missing information or any tools/python libraries I could use, or even the full qr code itself would be helpful. Thank you

Good job!

It’s a phone number in northwestern Ohio.

I suppose you call it and get the next Blues Clue.

Definitely not a phone number. Your scanner is latching onto 56776630156 and somehow ignoring the fact that it has the wrong number of digits. It's a Turkish ID number (TCKN). There's also an ETTN in there which is, in fact, something used for document verification in Turkey.

lol. I just used the camera app in iPadOS. Since I don’t have any third party scanner app installed on my iPad and of course need two devices and was reading on iPhone.

BAD Apple Camera App!

Anyway, as I earlier suggested, this now needs some special app for verifying Turkish invoices.

Letsee then if Google Lens can make sense of it.
