LIBERTY prefixes in area code 936

NANPA records 11 assigned NXX blocks to rate center LIBERTY in area code 936, 2.6% of the 422 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (3), AT&T ENTERPRISES, LLC (1), CENTURYLINK COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2002-03-29 and the most recent 2025-10-30. 10 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 207, 217, 326, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
