How area code 978 is used

Area code 978 is part of the public US numbering structure and works as a broad regional entry point. Inside it, multiple prefixes can exist, and those prefixes may connect to different local numbering hubs.

That is why area code pages are helpful: they give users a wider view first, then make it easier to narrow the search into local prefixes, rate centers and phone-specific pages.

For many searches, that is exactly the right workflow: start broad with the area code, then move to the smaller numbering layers that sit underneath it.
