How 544 is used

History
Creation: Area code 544 was placed into service on December 15, 2010 as the third 5YY non-geographic NPA, relieving 533. It was one of the original PCS relief codes (alongside 566, 577, 588 and 522) designated by the Industry Numbering Committee in the 1990s. Activation followed 533 by little more than a year as demand for non-geographic numbers grew faster than NANPA had originally projected.
Relieved: Area code 544 was activated to relieve 533.
Mnemonics: The digits 544 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.
