Area code 223 — South-central Pennsylvania
The second code for south-central Pennsylvania, in service since September 2017. It covers the state capital, Lancaster County and the Gettysburg battlefield on exactly the same footprint as 717 — and it arrived a full month after the dialling rules changed, which is the standard sequence for an overlay and the reason none of the new numbers failed on their first day.
New numbers available in 223Area code 223 covers south-central Pennsylvania: Harrisburg, Lancaster, York, Hershey, Gettysburg, Carlisle, Chambersburg and Lebanon.
It is an overlay on 717, so the two share every street. Having issued numbers only since 2017, 223 is where the region’s available supply sits.

How 223 came about
Approved, announced, dialled for, and only then switched on.
- Before 2017One code, running downSouth-central Pennsylvania has used 717 since 1947. By the mid-2010s its unassigned numbers are close to exhausted and the Public Utility Commission has to choose between splitting the territory and overlaying it.
- 2017An overlay is approvedThe Commission approves an all-services overlay: a second code across the same ground, with no existing number changing. A split would have divided the capital region and forced part of it onto new numbers.
- August 26, 2017Ten digits become mandatoryEvery local call in the territory must be dialled with the area code from this date — while 717 is still the only code in use. What was a local call stays a local call; only the dialling changes.
- September 26, 2017223 goes into serviceA month later, new customers begin receiving 223 numbers. By then every phone, alarm panel and stored contact in the region is already dialling ten digits, so the new numbers work immediately.
Which code should you choose?
Two codes cover south-central Pennsylvania, and they cover it identically.
| Code | Since | What it gives you |
|---|---|---|
| 223 | 2017 | The region’s available numbers, including patterned endings |
| 717 | 1947 | Seventy-eight years of recognition; thin supply |
| 570 | 1998 | North-east PA — Scranton and Wilkes-Barre |
| 610 | 1994 | The Lehigh Valley and the eastern suburbs |
Both are equally local to Harrisburg, Lancaster or York. Take 717 if you want the number the region has always recognised, 223 if you would rather choose the digits.
What people get wrong about 223
Is 223 used for spam calls?
223 is spoofed less than 717 simply because it is less familiar, and a forged number relies on being recognised. That is a comment on what works for the caller rather than a property of the code — any code can be displayed by anyone, and caller ID carries whatever the originating system sends rather than any proof of origin. The capital-region angle is worth knowing here: a caller claiming to be from a state agency gains credibility from a Harrisburg-area number on screen. State agencies publish their telephone numbers, so an unexpected demand is best answered by hanging up and dialling the published one.
Area code 223 FAQ
What area code is 223?
223 covers south-central Pennsylvania, including Harrisburg, Lancaster, York, Hershey, Gettysburg, Carlisle, Chambersburg and Lebanon. It is an overlay on 717 and covers the same territory.
Is 223 a real Pennsylvania area code?
Yes. It has served south-central Pennsylvania since 26 September 2017 and is where most new numbers in the region are issued.
What is the difference between 223 and 717?
Nothing geographic — they cover identical ground. 717 dates from 1947 and has little unassigned supply; 223 arrived in 2017 and holds most of the free numbers.
When did the 223 area code start?
Numbers began to be issued on 26 September 2017. Mandatory ten-digit dialling had started a month earlier, on 26 August.
Why did ten-digit dialling start before 223 existed?
So that nothing failed on the first day. Every phone system and stored contact in the territory had to be converted before a second code went live, since anything still dialling seven digits could not reach the new numbers.
Is a 223 number less local than a 717?
No. An overlay adds a code across the same territory rather than taking a piece of it, so 223 is exactly as local to Harrisburg or Lancaster as 717.
Does 223 cover Lancaster and Gettysburg?
Yes. The whole 717 footprint is shared, so Lancaster County, Gettysburg, York, Hershey and Carlisle are all in 223 as well.
Can I choose a memorable 223 number?
Much more easily than on 717. Having issued only since 2017, 223 holds the larger unassigned pool in the region, so repeated or patterned endings are more often available.
What time zone is the 223 area code in?
Eastern — UTC−5 in winter and UTC−4 under daylight saving, as all of Pennsylvania is.
How do I get a 223 business number?
Search 223 for the widest choice of digits in south-central Pennsylvania, or 717 if instant local recognition matters more. Neither requires a Harrisburg address.
Getting a 223 business number
223 numbers are still being issued, so a business anywhere can hold one and route it to wherever its team actually works — you do not need an address in Pennsylvania.
