BUDA prefixes in area code 737

NANPA records 7 assigned NXX blocks to rate center BUDA in area code 737, 2.1% of the 333 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), TERRA NOVA TELECOM INC. (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2013-03-04 and the most recent 2026-06-30. 7 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 309, 512 – overlay codes cover the same geography, so a rate center is served by all of them.
