WALDORF prefixes in area code 301
NANPA records 25 assigned NXX blocks to rate center WALDORF in area code 301, 3.2% of the 784 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. 8 holders hold those blocks, the largest being VERIZON MARYLAND, INC. (10), NEW CINGULAR WIRELESS PCS, LLC - DC (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MD (4). The earliest assignment on record here is 2005-12-30 and the most recent 2022-01-24. 14 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 227, 240, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
