SPRING prefixes in area code 281
NANPA records 35 assigned NXX blocks to rate center SPRING in area code 281, 4.5% of the 786 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. 10 holders hold those blocks, the largest being SOUTHWESTERN BELL (25), AERIAL COMMUNICATIONS, INC. (2), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (1). The earliest assignment on record here is 2008-03-26 and the most recent 2022-03-03. 22 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 346, 713, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
