Introduction
The 856 area code covers South Jersey — the Delaware Valley side of New Jersey, across the river from Philadelphia. Camden, Cherry Hill, Vineland, Gloucester, and the surrounding region all dial 856. It's a dense, suburban market with strong Philadelphia-metro ties and an economy built on healthcare, retail, logistics, and manufacturing.

Where 856 came from
The 1999 split from 609
The 856 area code was created on June 5, 1999, splitting from the 609 area code to serve the southwestern corner of New Jersey. The split separated South Jersey's Camden County metro from central and Shore Jersey's 609 footprint.
No overlay — still solo
Unlike much of New Jersey, 856 has never needed an overlay code. It remains the single area code for South Jersey's core counties — Camden, Gloucester, Salem, and Cumberland — plus parts of Atlantic and Burlington counties.
Ten-digit dialing
New Jersey requires ten-digit dialing statewide. Keep the full area code on all your business materials, CRM records, and listings.
What the 856 market looks like
The Philadelphia-metro connection
Cherry Hill and surrounding communities are effectively Philadelphia suburbs. Many 856 residents commute across the Ben Franklin or Walt Whitman Bridge. A South Jersey business serving this market needs both a local feel and the ability to connect with Philly-area buyers.
Camden County's healthcare and education anchor
Cooper University Health System, Rowan University, and a network of healthcare providers anchor Camden County's economy. Healthcare-adjacent businesses — billing, home care, medical staffing — find 856 a productive local market.
Vineland and the agricultural south
Further south, Vineland and Cumberland County run on food processing, agriculture, and light manufacturing. The 856 code connects you to a distinctly different customer profile from the suburbs — one where a local number matters even more.
