I grew up in Levittown. With that zip code, it may actually be in Fallsington, PA which is "right on the border".
To my knowledge there is no Main street in Levittown. If there were, It would be in the Magnolia Hill or Millcreek section or perhaps along a major road such as Haines Road, Route 13 etc, but the zip is different. Try Fallsington or let me know and I'll do some digging for you.
