Philadelphia Water Dept.

Philadelphia's corporate office category runs 198 listings deep, so narrowing down where to start matters more than scrolling the whole page. A large share, 65 entries, sit in zip 19103 alone, which tells you a lot of this activity is concentrated around Center City rather than spread evenly across the city. If you're trying to reach a specific type of office, checking that zip first can save time before you branch out to areas like 19102 or 19107.

None of these entries are tagged Sponsored right now, so nothing you see was placed here through paid promotion, and the order reflects plain directory data rather than a bought position. Most listings include a working phone number, and most also link to a website, so you'll usually have more than one way to reach a business before you pick up the phone. If you manage one of these offices and notice the contact details are wrong or missing, you can claim the listing yourself and correct it, which keeps callers from hitting a dead end. Scan a handful of entries in the zip codes above, then call two or three that match what you're actually looking for.
