Yes. State-aided public libraries and District Library Centers may choose to issue a free library card to someone who lives in a municipality that does not support public library services for its residents. (Or, the library may choose to charge a fee for a library card; or it may choose to not issue one at all.)
Note that if a card is issued, it should not have the Access PA logo on it. As required by the Pennsylvania Public Library Code, people may only participate in the Statewide Library Card Program if they live in a municipality that supports a state-aided public library.
