724 Area Code: Western PA Numbers Explained

Quick answer: The 724 area code covers Western Pennsylvania outside the City of Pittsburgh — Greensburg, Beaver, Butler, Indiana (PA), Washington, Uniontown, New Castle, Kittanning, Latrobe, Connellsville and 60+ other towns across roughly 17 counties. It was split from 412 on February 1, 1998, sits in Eastern Time, and shares its territory with the 878 overlay (added September 2001). Because two codes ring the same neighborhoods, 10-digit dialing is required for every local call.

Everything you need to know about the 724 area code

Pick up a call from a 724 number and you're almost certainly hearing from somewhere in western Pennsylvania — the suburbs and exurbs that ring Pittsburgh, plus the rural counties stretching out toward Ohio and West Virginia. It's been the region's secondary calling identity for nearly three decades.

This guide breaks down where 724 reaches, how the 878 overlay works, the dialing rules, and how to claim a local western PA number from anywhere.

Where the 724 area code covers

The 724 area code rings the horseshoe of western Pennsylvania around Pittsburgh: the suburbs that arc out from the city limits, plus the smaller industrial towns and rural counties that extend toward Ohio (in the west) and the Allegheny Mountains (in the east).

It does not cover the City of Pittsburgh itself — that's 412 (plus 878 as an overlay there too).

The horseshoe of cities

• Greensburg — Westmoreland County seat, the eastern anchor
• Beaver — Beaver County seat, north-west of Pittsburgh
• Butler — Butler County seat, due north
• Washington — Washington County seat, south-west
• Indiana — Indiana County seat, east
• Uniontown — Fayette County seat, south
• New Castle — Lawrence County seat, far north-west
• Kittanning — Armstrong County seat, north-east of Pittsburgh
• Latrobe · Connellsville · McKeesport (parts) · DuBois · Punxsutawney — major towns
• Plus 60+ smaller boroughs, townships, and unincorporated communities

How 724 and 878 work together

Western PA used to be all 412. Two waves of growth changed that:

1998: The split

By the mid-1990s, 412 covered all of western PA — Pittsburgh, every suburb, every rural town. Number-supply exhausted.

On February 1, 1998, the PA PUC carved off the suburbs and rural counties and assigned them 724. The City of Pittsburgh kept 412.

2001: The overlay

Three years later, 724 itself ran low on inventory. Rather than re-carve the region, the PUC layered an overlay code, 878, on top of the same 724 footprint.

The 878 overlay went into service in September 2001.

What it means today

• Existing 724 numbers stayed 724. Nobody had to renumber.
• New numbers issued after 2001 can come from either the 724 pool or the 878 pool. Today, most new lines are 878 because 724 inventory is largely allocated.
• An 878 number is not "lesser" than a 724 number — they cover the identical western PA geography.
• 10-digit dialing is mandatory for every call, even calling next door.

How the 724 area code works

724 is a standard 10-digit phone number in the North American Numbering Plan (NANP). The format follows NPA-NXX-XXXX:

• 724 — NPA (area code)
• NXX — three-digit central-office prefix
• XXXX — four-digit subscriber line number

Why a 724 number helps your business

Caller ID is the first impression. A familiar 724 prefix tells a Beaver County, Westmoreland County, or Washington County resident that the call is local before they even pick up.

For sales, service businesses, clinics, and contractors targeting western PA customers, that pickup-rate lift compounds into real revenue.

The local trust advantage

A 724 number signals you're part of the community — not a faraway call center in Texas or a Mumbai-based outbound team. In smaller western PA cities where word-of-mouth matters, local-looking businesses get more answered calls.

Reach without an office

You can hold a 724 number while working from Denver, Dublin, or anywhere with internet. A virtual number forwards calls to any device — your "local" presence follows your team wherever they work.
