Do Envelopes have bar-codes?
Hi Everyone, I have lurked here off and on for a couple of years and now I have a question that I think perhaps someone here might be able to answer for me.
Often times we get empty envelopes with a billing or similar mailings we receive. I have not thrown these away, but I save them. I just hate to waste something.
Many of them are just plain envelopes, which I have used to mail things. But also many of them have lines like a bar code on them. I am wondering if these lines are a bar code and would send the envelope to a pre-arranged address. So I haven't used them just in case.
Does anyone know about these lines/barcodes?
