Unleashing business potential in the Old Line State

Anchored in the Mid-Atlantic, Maryland's business landscape is as diverse as its geography. Known as "America in Miniature" due to its varied topography within its borders, Maryland offers a broad range of business opportunities, from the bustling urban centres of Baltimore and Rockville to the biotech hotspots of Silver Spring and Frederick. With an intricate network of area codes serving different regions, businesses can find their niche in the Old Line State.

Located within the 240 and 301 phone numbers, regions such as Germantown, Silver Spring, Waldorf, Frederick and Rockville have established themselves as leaders in biotech and life sciences. Home to numerous biotech firms, research labs and healthcare institutions, these regions offer a conducive environment for businesses in the life sciences sector to grow and innovate.

Urban business hubs: Baltimore and beyond

The 410 phone number serves Baltimore, a city boasting a diverse economy with strong sectors in health, education and tech. Its strategic location and rich industrial heritage make it an attractive destination for businesses. Meanwhile, the 443 phone number and 667 phone number serve eastern Maryland, including the Baltimore metropolitan area, Annapolis, Columbia, Glen Burnie, Ellicott City and Dundalk. These vibrant, urban areas offer unique opportunities in sectors ranging from manufacturing and maritime trade to creative arts and tourism.

Why the overlapping area codes?

In regions like western Maryland and eastern Maryland, you might notice multiple area codes serving the same regions. This is due to the increasing demand for new phone numbers. As populations grow and businesses expand, new area code numbers like 240 and 667 have been introduced as overlays to the existing 301 and 410/443 area codes, respectively. These overlay area codes ensure that there's a steady supply of new numbers for the area's thriving businesses and growing population.
