All 313 prefixes (NXX)
The table lists all 763 active prefixes registered under 313. A prefix ({NXX{'}'}) is the second three-digit group of a US number; its row shows where the block is anchored and who holds it.
35 carriers hold 313's prefixes across 6 rate centers; the biggest concentration is Detroit Zone 05 with 270. Thousands-block pooling covers 479 prefixes (63%), so a prefix's code holder is not necessarily the carrier of a given number in it.
