Talk:Tinicum Township, Delaware County, Pennsylvania

old zipcode in part of the township
Lester used to be zipcode 19113. From what I can tell, it was merged into Essington 19029 to avoid having a Philadelphia (191xx) zipcode in a place which is not in Philadelphia. — Preceding unsigned comment added by 128.63.16.82 (talk) 17:16, 30 April 2012 (UTC)
