Official Website

of the Commonwealth of Pennsylvania

    The .gov means its official.

    Local, state, and federal government websites often end in .gov. Commonwealth of Pennsylvania government websites and email systems use "pennsylvania.gov" or "pa.gov" at the end of the address. Before sharing sensitive or personal information, make sure you're on an official state website. 

    Access to the member contact list is for COSTARS-authorized suppliers only.  

    To find the member contact list, suppliers must log in to the PA Supplier Portal and enter the COSTARS gateway.
