For a product to be kosher it must have the hecher ( U with a circle
around it). If there is a P next to the hecher the product is
acceptable for Pesa (Passover). That is, it doesn't have the five
grains the Jewish religion avoids during Passover. In essence, it is
GF. There is an exception and that is some communities allow
Matzoh. So one would have to verify that the product is Matzoh free.

You don't have to go to a Jewish community.  Most stores have a kosher
section.  Although I am sure there is more of a selection in a Jewish
community.
