Massachusetts business phone guide

Massachusetts by the numbers

Massachusetts had 7.1 million residents in the Census Bureau's July 2024 estimate, up 1.5% from April 2020. The U.S. population grew 2.6% over the same period. County Business Patterns counted 183,767 business establishments in the state in 2023 with 3,487,228 mid-March employees and $301.8 billion in annual payroll. The average establishment has 19.0 employees. 53.7% of establishments with employees had fewer than five people. The three largest sectors by establishments are retail trade (22,550), professional, scientific, and technical services (21,966), and construction (21,631).

Business density and team size in Massachusetts

Massachusetts has 25.8 business establishments per 1,000 residents, 4.7% above the U.S. figure of 24.6. Establishments average 19.0 employees against 16.7 nationally, and payroll per employee is $86,550 (26.6% above the U.S. $68,342). 53.7% of establishments with employees have fewer than five people (U.S.: 55.5%), while 6.1% have 50 or more. Most establishments are far smaller than the average suggests, so it pays to price a phone plan at the headcount you actually have rather than the average.

Picking a local number in Massachusetts

8 of Massachusetts's 9 area codes require ten-digit dialing for local calls; in the others NANPA still lists seven-digit local dialing. In overlays (351/978, 339/781, 617/857, and 508/774), the codes share one territory, so a new number may come from any code in the overlay. A business that serves one city usually takes a number in that city's dominant code; one that covers a region can hold up to 3 local numbers on Callata's plan.

225 Massachusetts cities and towns have their own local-number page. The most populous are Boston (617/857), Worcester (508/774), Springfield (413), and Cambridge (508/617).

If you already have a number in Massachusetts, porting it to Callata is free. Texting from a local number requires a one-time carrier registration (10DLC, $49), and the numbers available in any area code depend on carrier inventory when you choose them.

Optional AI agents (receptionist, sales, support or scheduler) can answer calls after hours or when nobody picks up, take messages, text, email and transfer to your team. They are billed from prepaid AI minutes at $0.25 per minute, identify themselves as AI, and may only place outbound calls to people who consented, between 8am and 9pm.
