Area code 610

Where area code 610 is

NANPA lists 610 as an in-service geographic area code for Pennsylvania, first put into service on January 8, 1994. It is an overlay: 610 and 484 and 835 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 Allentown, Reading, Bethlehem, West Chester, and Easton. By population, its largest named places are Allentown, Reading, Bethlehem, Easton, and Pottstown.

Places served by 610

610 holds 9.5% of the 8,256 central office codes assigned in Pennsylvania, the 8th most of the state's 15 codes. 49 Census places could be matched to rate centers with 610 exchanges; the most populous are Allentown (127,000), Reading (96,000), Bethlehem (79,453), and Easton (30,432). Each place page lists the exact prefixes and carriers for that town.

Ten-digit and seven-digit dialing in 610

According to NANPA's dialing-plan data, local calls within 610 are dialed as ten digits (area code plus number) and toll calls as ten digits (area code plus number). Because local calls need the area code, business cards, signage and website copy should always show the full ten-digit number. NANPA's dialing-plan note for this code reads: "1+10 digit dialing for all HNPA and FNPA calls permissible at each service providers discretion."

Who holds 610 exchanges

41 carriers hold the 782 central office codes assigned in 610. Verizon Pennsylvania, INC. has the most, with 322 (41%). 433 of the codes (55%) are pooled, meaning the code holder shares blocks of 1,000 numbers with other carriers instead of using all 10,000 itself. The code holder is not necessarily the carrier serving a given number today, since numbers can be ported between providers.

Rate centers and towns in 610

NANPA assigns each central office code to a rate center, the local calling area that decides whether a call is local or toll. 610 has codes in 90 rate centers. Rate center names in the file are abbreviations; where one matches a Census place, the table links to that city's local-number page.

610 code assignments over time

An area code has 800 possible central office codes that start with 2 through 9, a few of which are reserved (such as N11 service codes and 555). 782 are assigned in 610, 98% of 800. 11 were assigned in 2020 or later.

AI agents are optional: an AI receptionist or scheduler can pick up when the team is busy or closed, take a message, send a text or email, or transfer the call. They draw on prepaid AI minutes ($0.25/minute), disclose that they are AI, and outbound AI calls require prior consent and are limited to 8am–9pm.
