How 527 is used

History
Creation: Area code 527 was placed into service on September 29, 2021 as the thirteenth 5YY non-geographic NPA, relieving 526. It was one of the relief codes set aside in NANPA's May 2012 Planning Letter 703 to expand the 5YY pool. Activation pace in 2020-2022 reflects roughly one new 5YY code every six to eight months.
Relieved: Area code 527 was activated to relieve 526.
Mnemonics: The digits 527 map to letter combinations on the standard telephone keypad, yielding 36 possible three-letter mnemonics. Prior to 1995, the middle digit of area codes was restricted to 0 or 1 — codes created before then cannot form mnemonics.
