500 is an in-service non-geographic North American area code for non-geographic services. It is not tied to a city or state.
The NANPA source lists 533, 544, 566, 577, 588, 521, 522, 523, 524, 525, 526, 527, 528, 529, 532, 538, 542, 543 in the same overlay complex. An overlay can serve the same broad numbering area; individual numbers still do not prove where a person is.
Enter the full ten-digit number to see its structure and formatting. The check stays in your browser.
Enter a 10-digit +1 North American number. We check its structure and area-code record, not the caller’s identity or whether the line is active.
Processed locally in your browser. Nothing you enter is sent to OfficialAreaCode or saved.
The displayed number may be spoofed. Do not rely on an area code as proof of caller identity. If the caller claims to represent a business, end the call and contact that business using a number you found independently.
No. An area code is an assignment, and a person can travel, move, use internet calling, or display a spoofed number.
No. OfficialAreaCode has no live subscriber directory or spam-report database.
