When generating the GS1 Digital Link URI for encoding in a 2D barcode, is it ok to include additional details or sub-directories/sub-folders before the GS1 identifier (e.g. "01/" or other valid AIs)?

Examples for clarity:
https://www.example.com/[subfolder]/[subfolder]/01/[GTIN]
or https://www.example.com/[subfolder]/8003/[GRAI]

Yes, It is ok and valid to add extra details to your GS1 Digital Link URIs before the GS1 identifier. Just make sure that:

• it doesn’t make the entire URL unnecessarily long, resulting in an overly large 2D barcode
• it doesn’t contain “/01/” (or any other GS1 identifiers) as this would prematurely indicate the start of the GTIN (or other GS1 identification keys)

Tip: Adding additional details or sub-directories/sub-folders before the GS1 identifier remains valid because everything to the left of the actual GS1 identifiers is not part of the identification of the item.
