Oh and mouser, if you're using customer part numbers (i have some overstock bags that a customer bought me years ago that use part numbers in their database system), does not include the MPN anywhere in the barcode. So those are basically useless and will probably have to get relabeled with a house label that actually includes the MPN. Modern digikey bags will use P, 1P, and 30P tags so you get MPN, customer part number, and digikey part number unambiguously. But older digikey bags and other distributors don't do that.
