MONTGOMERY prefixes in area code 334
NANPA records 168 assigned NXX blocks to rate center MONTGOMERY in area code 334, 21.4% 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. 32 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (48), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (29), NEW CINGULAR WIRELESS PCS, LLC - GA (12). The earliest assignment on record here is 2001-01-03 and the most recent 2026-09-08. 100 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 272, 304, 318, 483 – overlay codes cover the same geography, so a rate center is served by all of them.

It is a rate center – the unit NANPA allocates number blocks to. Its name is abbreviated to ten characters and is not necessarily a settlement: we print it as recorded rather than guess at the full name.
