Commonwealth Telephone Directory

Welcome to the Commonwealth of Pennsylvania’s online telephone directory.

2025 Commonwealth Telephone Directory PDF

The Commonwealth Telephone Directory is available as a PDF. It is identical to the printed version but has the ability to be searched and navigated quickly. The online pdf is updated up to four times per year, so it will always be a more accurate resource for up-to-date information.

If you are viewing the pdf on a desktop computer, bookmarks will be available for easy navigation throughout the directory. To search the directory, click the magnifying glass, use Command/Control F, or utilize the Index at the back of the directory.

If viewing the pdf on a mobile device, it is recommended that you download the pdf to your device and open it with the Acrobat Reader app. It may be viewed without downloading, but bookmark navigation will be unavailable.

Updates are accepted by the Bureau of Publications’ Editor ONLY through your Agency's​Commonwealth Telephone Directory Coordinator on specified dates. If you are a new coordinator, please review the step-by-step instructions for modifying your agency’s directory listing and reach out to the directory editor for further clarification about the process at RA-comteldir@pa.gov .
