Area Code 947 Location

Area code 947 serves Farmington Hills, Michigan, and much of Oakland County in the northwest part of the Metro Detroit region. It is an overlay of area code 248, which means both codes cover the same geographic area and new phone numbers may be assigned either code. Because of this overlay, callers use 10‑digit dialing for local calls. The area follows the Eastern Time Zone and includes a mix of residential neighborhoods, corporate campuses, and major shopping areas.

Common communities covered by the 947/248 overlay include:

• Troy
• Southfield
• Pontiac
• Novi
• Royal Oak
• Rochester Hills
• Farmington
• Bloomfield Township It also reaches popular landmarks like the Detroit Zoo in Royal Oak and Oakland University in Rochester Hills/Auburn Hills, along with the Zekelman Holocaust Center in Farmington Hills. These destinations help make the 947 area code a hub for culture, education, and business in suburban Detroit.

Area code 947 was added in the early 2000s to expand numbering capacity for the busy 248 region as wireless phones and businesses grew. As an overlay, it did not change boundaries; it simply provided more numbers while keeping existing 248 numbers in service. If you see a 947 phone number, it most likely points to a line in Farmington Hills or nearby Oakland County communities.
