603 Area Code Details

603 Area Code: A Piece of New Hampshire History

The 603 area code was created in 1947 and is tied exclusively to New Hampshire. It covers iconic neighborhoods like:

Manchester – the vibrant heart of the state

Nashua – known for its culture and community

Concord – the historic state capital

For generations, 603 has represented New Hampshire pride, offering the best of state life with fast access to all towns.

The 603 area code operates in the Eastern Time Zone (ET)–the same time zone as New Hampshire. This is important for businesses and professionals who need to stay in sync with local clients, suppliers, and partners. Whether you’re scheduling calls, running local ads, or managing customer support, having a 603 number means you’re aligned with Eastern Standard Time (EST) in winter and Eastern Daylight Time (EDT) in summer.

The 603 area code covers all of New Hampshire, including:

Manchester

Concord

and many more.
