ARLINGTON prefixes in area code 817
NANPA records 229 assigned NXX blocks to rate center ARLINGTON in area code 817, 29.3% of the 781 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. 19 holders hold those blocks, the largest being SOUTHWESTERN BELL (66), T-MOBILE USA, INC. (48), NEW CINGULAR WIRELESS PCS, LLC - IL (31). The earliest assignment on record here is 2001-01-16 and the most recent 2026-10-08. 123 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 229, 270, 334, 339 – overlay codes cover the same geography, so a rate center is served by all of them.
