Who works in the Woburn area?

Woburn sits nine miles north of Boston at the junction of I-93 and I-95, and that position made it one of the suburban business hubs of Massachusetts. The city's office and industrial parks along the highway belt house biotech and life-sciences firms, medical device makers, engineering companies, and the logistics and lab-services operations that support the Cambridge research cluster without paying Cambridge rents. Woburn's city motto is "Industry and Virtue," and the industry part still holds, though it now means clean rooms and lab space more than the tanneries the city was once known for.

Who lives in the 339 region

The workforce reflects a prosperous inner suburb. Woburn's population was 40,876 at the 2020 census and reached an estimated 41,939 in 2024, with a median household income of $111,185 and a median age of 39.3 (DataUSA, 2024). About 20% of residents were born outside the country (DataUSA, 2024). After English, the languages a business is most likely to encounter locally track the region's larger immigrant communities, including Portuguese speakers from Brazil, Spanish, and Chinese, though no single non-English language dominates the city.

What a 339 number signals to a caller

Area code 339 has overlaid 781 since 2001, covering the ring of suburbs around Boston, so a 339 number reads as local anywhere from Waltham to Lynn. Callers describe business communication in the region as direct and appointment-driven, with weekday hours observed fairly strictly and voicemail returned rather than answered live. An outside caller should know that ten-digit dialing has been the norm here for over two decades, and that a 339 number carries no less local weight than the older 781.
