GRAHAM prefixes in area code 940

NANPA records 9 assigned NXX blocks to rate center GRAHAM in area code 940, 1.8% of the 506 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. 7 holders hold those blocks, the largest being SOUTHWESTERN BELL (3), WEB FIRE COMMUNICATIONS, INC. - TX (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-09-13 and the most recent 2024-03-22. 6 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 253, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
