SOMERVILLE prefixes in area code 901
NANPA records 13 assigned NXX blocks to rate center SOMERVILLE in area code 901, 2.1% of the 616 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (3), ONVOY, LLC - TN (3), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2). The earliest assignment on record here is 2001-02-26 and the most recent 2026-04-08. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 617, 857, 908, 979 – overlay codes cover the same geography, so a rate center is served by all of them.
