Area Code 521 History and Coverage
Area code 521 went into service on September 21, 2017, having been allocated as part of the expanding 5XX non-geographic numbering resource. In May 2012, NANP planning identified area codes 521 and the rest of the 5XX series as an addition to the numbering resources known as 5YY personal communications codes. Later, the designation was widened to include additional non-geographic uses, as well as those using fixed and mobile telephones, and even those using machine-to-machine services.
Unlike other North American area codes, the geographical background of the area code 521 does not fit into the pattern of state-based geography. While any area code normally defines a geographical area by drawing its boundaries at the metro areas, counties and states, code 521 has no geographical background to draw from. It has neither rate center nor historic area spanning any geographical area in the country. Therefore, it did not create any new geographical area from any existing area code and should not be viewed as representing any community based on the availability of the number in the lookup results.
Historically, area code 521 belongs to the group of in-service non-geographic numbers including 500, 522, 523, 524, 525, 526, 527, 528, 529, 532, 533, 544, 566, 577, and 588.
