How can I tell whether these envelopes are really "prepaid" for usps mailing?
I work at a university where we have envelopes with the logo/address on the top-right, and a uniform height barcode below the address on the middle-left. I've been told by some people from the office that these envelopes don't need a stamp (i.e. they are prepaid). However, when I called USPS and asked, the lady had no idea what this barcode was, or anything about it, and that I would need stamps. I need to send a lot of important mail today (a few hundred), so I need to know for sure whether these envelopes are valid.
There is a 6 digit number above the barcode, in the format
The barcode itself looks to be about 80 lines long, with single-wide lines and triple-wide lines.
Are there any mail experts that can tell me whether I can just send these off?
