Quick answer: The 717 area code covers south-central Pennsylvania — anchored by the three cities of Harrisburg (the state capital), Lancaster (Pennsylvania Dutch country), and York (the White Rose City). It's one of the original 1947 NANP codes, sits in Eastern Time, and shares its territory with the 223 overlay (added October 2014). 10-digit dialing is required for every local call.
What is the 717 area code?
A 717 number on caller ID puts you somewhere in the Susquehanna Valley + Pennsylvania Dutch country — Harrisburg, Lancaster, York, Hershey, Carlisle, Lebanon, Chambersburg, and the small towns and farm country between them.
It's been south-central PA's calling identity since 1947, when the original NANP launched. Today it shares territory with 223, the overlay added in 2014 to expand the number supply.

Where 717 reaches — three anchor cities
Pillar 1: Harrisburg (the state capital)
Harrisburg sits on the east bank of the Susquehanna River in Dauphin County (~50,000 people). It's the seat of Pennsylvania state government, home of the Capitol dome, and the I-83 / I-81 / I-76 highway crossroads. The economy is government, healthcare, insurance, and logistics.
Around Harrisburg: Mechanicsburg, Camp Hill, Lemoyne, New Cumberland, Hummelstown, Hershey (the chocolate town + Hersheypark), and Carlisle (US Army War College, Dickinson College).
Pillar 2: Lancaster (Pennsylvania Dutch country)
Lancaster is the largest city in the 717 footprint (~58,000 people) and the heart of Lancaster County — the country's most famous Amish and Mennonite agricultural region. The economy is agriculture, tourism, healthcare (Penn Medicine Lancaster General), and Franklin & Marshall College.
Around Lancaster: Lititz, Ephrata, Strasburg, Elizabethtown, Columbia, Mountville, Manheim, Mount Joy, Marietta.
Pillar 3: York (the White Rose City)
York (York County, ~44,000 people) is the western pillar — across the Susquehanna from Lancaster. Notable for being the first capital of the United States under the Articles of Confederation (1777–1778). Manufacturing economy, with Harley-Davidson's largest assembly plant and a strong industrial base.
Around York: Hanover (where Snyder's of Hanover pretzels are made), Gettysburg (the Civil War battlefield, just southwest), Red Lion, Dallastown, Wrightsville, Glen Rock.

How 717 and 223 work together
South-central PA used 717 alone for 67 years. By the early 2010s, numbers were running low. Rather than re-carve the region geographically, the PA PUC layered a second code on top.
1947: 717 launches
When the NANP went live in 1947, 717 was one of Pennsylvania's three original area codes — alongside 215 (Philadelphia) and 412 (Pittsburgh). The 717 footprint at launch was huge: south-central PA, the Poconos, and northeastern PA.
1998: 570 splits off
In 1998, the northeastern half (Scranton, Wilkes-Barre, the Poconos) split off as 570. 717's footprint shrank to its current south-central form.
October 2014: 223 overlay
On October 4, 2014, the 223 overlay went into service. Same exact 717 territory, second pool of available numbers.
What it means for you
- Existing 717 numbers stayed 717. Nobody renumbered.
- New numbers issued after 2014 can come from either pool — 717 or 223.
- A 223 number is not "lesser" than a 717 number — they cover identical south-central PA geography.
- 10-digit dialing is mandatory for every local call.

Why a 717 number helps your business
A 717 line tells a Harrisburg state agency, a Lancaster restaurant, or a York manufacturer that you're part of the south-central PA community.
- Higher pickup rates on outbound. Familiar local prefixes get answered.
- Geo-targeted ads land harder when the call-back number is local. A 717 on a billboard reads as a neighbor.
- Vanity numbers double as advertising —
717-CAPITOL,717-AMISH,717-LANCASTER,717-HERSHEY.
And because it's a virtual number, you can hold a 717 line while based anywhere with internet.
