LANCASTER prefixes in area code 223

NANPA records 12 assigned NXX blocks to rate center LANCASTER in area code 223, 4.8% of the 252 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 ONVOY, LLC - PA (4), D&E/OMNIPOINT WIREL JOINT VENT LP DBA PCS ONE (2), PEERLESS NETWORK OF PENNSYLVANIA, LLC - PA (1). The earliest assignment on record here is 2017-08-31 and the most recent 2026-01-13. 12 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 218, 220, 603, 608 – overlay codes cover the same geography, so a rate center is served by all of them.
