Area code 248 serves Oakland County in southeastern Michigan, one of the state’s wealthiest and most economically active regions. Introduced in 1997 as a split from area code 810, and later overlaid by 947, it includes cities like Troy, Southfield, Farmington Hills, Bloomfield Hills, and Novi. These suburbs of Detroit are known for a high concentration of white-collar professionals, strong public schools, and diverse corporate campuses. Troy is a major business and retail center, home to the Somerset Collection and global offices like Flagstar Bank and Kelly Services. Southfield hosts a significant number of law firms, tech companies, and media outlets.

The 248 area code is ideal for businesses seeking proximity to Detroit without being based in the city proper. It signals affluence, access to talent, and established infrastructure. Whether you're in finance, healthcare, education, or advanced manufacturing, a 248 number puts you in the heart of one of Michigan’s most desirable and opportunity-rich corridors.
