Pray tell, how would barcode be used as an adjective? Barcode is a NOUN.

barcode is one word. and you cannot say barcode label. barcode is a noun. barcode is a label and it therefore is unnecessary to say barcode label. and bar code as two words would probably refer to the code of conduct at a bar.

sorry but I’m not only answering to the asker, I’m answering to the answerers!!!

a noun can become an adjective and vice versa.
an hourglass is a noun, but you can have an hourglass figure!

as for bar code its 2 WORDS!!!! check it out…
