542 area code — NANP AREA non-geographic

Data: NANPA public reports, current as of July 28, 2026.

Phone numbers beginning 542 are registered in NANP AREA (Eastern time zone). The code entered service on May 26, 2026. It is part of the 500/521/522/523/524/525/526/527/528/529/532/533/538/542/544/566/577/588 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 542 number can be used from anywhere — the code marks where the number was assigned.

542 was created from 500 in 2026.

Practical takeaway: the 542 label narrows geography, the prefix narrows it to a locality, and neither authenticates a caller. Verification means calling back through a number you found yourself.

542 is a non-geographic service code (Non-Geographic Services): it is not tied to any state or rate center, and its numbers are assigned under service-specific rules rather than the geographic central-office process. Public prefix tables therefore do not apply to this code.

FAQ

Why do 500 and 542 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.

Why am I getting spam calls from 542 numbers?

Scammers spoof real area codes so calls look legitimate. A displayed 542 number does not prove the call originated there — see our guide to spotting spoofed calls.

Where is a 542 number from?

542 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 542 a toll-free number?

No. 542 is a non-geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
