View Full Version : What are these vertical marks on this envelope?

I mailed in my car insurance payment today, and used two 37-cent stamps. I used the envelope which came with the insurance bill, which had a plastic window in it for the return address.

The envelope also had a set of black vertical lines on the top edge, about 2.5 inches away from the upper-right corner. Five of them, covering a one-inch square. The lines were spaced somewhat like this:

|| | ||

Because the stamps I used were rather oversized, they obscured these lines. If I had used normal-sized stamps, the lines would have been visible.

I assume these things serve some purpose - what is it? Should I be concerned that State Farm will never receive my payment because I've interfered with some system of theirs, or the post office?

They are called Facing Identification Marks (http://en.wikipedia.org/wiki/Facing_Identification_Mark). Don't worry, it won't slow your envelope down by much.
