TYLER prefixes in area code 903

NANPA records 75 assigned NXX blocks to rate center TYLER in area code 903, 9.7% of the 771 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. 11 holders hold those blocks, the largest being SOUTHWESTERN BELL (32), NEW CINGULAR WIRELESS PCS, LLC - IL (15), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (14). The earliest assignment on record here is 2001-01-08 and the most recent 2023-12-12. 41 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 430, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
