FAQ

Where is a 588 number from?

588 is assigned to NANP AREA in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.

Is 588 a toll-free number?

Why do 500 and 588 cover the same place?

They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 500/521/522/523/524/525/526/527/528/529/532/533/538/542/544/566/577/588 complex shares one service area, and local calls are dialed with 10 digits.
