Area code 781

Where area code 781 is

Area code 781 is a geographic area code in Massachusetts, in service since September 1, 1997, according to the North American Numbering Plan Administrator (NANPA). It is an overlay: 781 and 339 cover the same territory, so neighbors on the same street can have different area codes. It is in the Eastern time zone. The places with the most assigned exchanges include Waltham, Lexington, Burlington, Lynn, and Woburn. By population, its largest named places are Lynn, Malden, Waltham, Revere, and Weymouth Town.

Where 781 numbers are local

781 holds 16% of the 4,743 central office codes assigned in Massachusetts, the 2nd most of the state's 9 codes. 39 Census places could be matched to rate centers with 781 exchanges; the most populous are Lynn (103,000), Malden (66,693), Waltham (65,849), and Revere (60,702). For a storefront or service area inside 781, the place pages show which prefixes are rated local there.

How calls are dialed in 781

According to NANPA's dialing-plan data, local calls within 781 are dialed as ten digits (area code plus number) and toll calls as 1 plus ten digits. Ten-digit local dialing means the area code is part of how customers save and recognize your number, so print it in full everywhere. NANPA's dialing-plan note for this code reads: "1+10 digit permissible at service provider discretion"

Phone companies in area code 781

27 carriers hold the 769 central office codes assigned in 781. Verizon New England INC. has the most, with 225 (29%). 598 of the codes (78%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. Numbers can move between carriers through porting, so a code's holder tells you where the block started, not where every number lives now.

Rate centers and towns in 781

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 781 has codes in 40 rate centers. The table lists the rate centers with the most codes, with the matching Census place where the abbreviation could be matched.

Using area code 781 for business calls

For $99 a month, Callata puts a team of up to 5 on one plan ($20 for each person after that): up to 3 local numbers, unlimited inbound calls, a pooled allowance of 1,500 outbound US and Canada minutes per user, browser and cell calling, voicemail transcription with urgency triage, recorded calls with AI summaries and business-hours routing, with E911 on every number.

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.
