My son had a jar of Peter Pan with that code and is mailing the jar lid back to ConAgra.
That probably explains why he got sick back in January when he got the jar. Thank God he didn't continue eating it, he had a jar of something else he wanted to finish up first...
Whew!
I called the 800 number and they have a recording telling people to mail the lid with the code to them along with your name and address.
