Barcode activation on imported data

[IKRCGC]

Imported Excel database with our inventory and another department's inventory, all now within the same location.  Our barcodes work but theirs don't.

There should be no activation for Barcodes to work.  Since you imported 2 databases did you import them both as GTIN or SKU.  If you imported the one that is no longer working you may have imported them as a GTIN which has specific rules and the amount of characters and the types of characters whereas SKU is more forgiving.  Since Excel only imports Barcodes as TEXT, your texts fields could be missing a character or have extra characters. 

Can you take a Picture with a Barcode Reader app to see the characters on one of the barcodes that is not reading, then enter that into the Excel spread sheet or Squares CSV item list search to see which column or field the non readable barcode text is in?  Or just look at your Square Items fields on your Square Dashboard?  Make sure the Barcode that does not read is matching the GTIN or the SKU completely.
