SAN MARCOS prefixes in area code 512
NANPA records 26 assigned NXX blocks to rate center SAN MARCOS in area code 512, 3.3% of the 785 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. 6 holders hold those blocks, the largest being BRIGHTSPEED OF SOUTHERN TEXAS, INC. (11), T-MOBILE USA, INC. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (4). The earliest assignment on record here is 2006-04-27 and the most recent 2015-03-27. 18 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 442, 737, 760 – overlay codes cover the same geography, so a rate center is served by all of them.
