History
Creation: Area code 524 was placed into service on July 12, 2019 as the tenth 5YY non-geographic NPA, relieving 523. It was among the relief codes reserved in NANPA's May 2012 Planning Letter 703 to expand the 5YY pool first opened with area code 500. Activation timing reflects the steady demand for caller-paid PCS and machine-to-machine numbering.
Relieved: Area code 524 was activated to relieve 523.
Mnemonics: The digits 524 map to letter combinations on the standard telephone keypad, yielding 27 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.
