History
Creation: Area code 533 was placed into service on September 26, 2009 as the second 5YY non-geographic NPA, relieving 500. The Industry Numbering Committee had originally designated 533, 544, 566, 577, 588 and 522 in the 1990s as future PCS/non-geographic relief codes, and 533 was the first of those to be activated. Subsequent 5YY activations followed at roughly two-year intervals.
Relieved: Area code 533 was activated to relieve 500.
Mnemonics: Prior to 1995, the middle digit of area codes was restricted to 0 or 1 — codes created before then cannot form mnemonics.
