SANANTONIO prefixes in area code 726
NANPA records 114 assigned NXX blocks to rate center SANANTONIO in area code 726, 100.0% of the 114 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. 33 holders hold those blocks, the largest being ONVOY, LLC - TX (15), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (14), FRACTEL, LLC (11). The earliest assignment on record here is 2017-08-23 and the most recent 2026-10-26. 114 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 210, 352, 408, 669 – overlay codes cover the same geography, so a rate center is served by all of them.
