Introduced in 2017 to accommodate growing demand, 223 covers cities like Harrisburg, Lancaster, York, and Gettysburg. This region is known for its historic significance, agricultural economy, and rapidly expanding logistics and healthcare sectors.

Lancaster blends old-world charm with modern enterprise, featuring a robust tourism industry driven by Amish heritage and thriving small businesses. York supports major manufacturing operations, while Gettysburg remains a national destination for history enthusiasts. The region also benefits from strategic location—within a few hours of Philadelphia, Baltimore, and Washington, D.C.—making it ideal for distribution and regional commerce. The 223 area code allows businesses and individuals to maintain a local identity while accessing a growing number pool. Whether you’re in government, education, agriculture, or logistics, a 223 number connects you to a diverse and historic region of Pennsylvania with strong community roots and growing economic relevance.
