North American Communications was originally founded as Metro Envelope out of Harlem, New York in 1934. Over the course of the following years, this operation grew steadily. As it became apparent that there was a solid and increasing need for these services, expansion was inevitable. Metro Envelope pushed to Duncansville, Pennsylvania, where it became North American Communications. With two fully functional manufacturing locations, NAC has become the nation’s largest, bi-national, fully integrated direct mail supplier.
