SELMER prefixes in area code 731

NANPA records 10 assigned NXX blocks to rate center SELMER in area code 731, 2.5% of the 395 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 BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), TELNYX LLC (1), ONVOY, LLC - TN (1). The earliest assignment on record here is 2002-04-10 and the most recent 2024-04-26. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
