City population is shown in full. The share of each city inside 878 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.
What counties does area code 878 cover?
2,677,445 residents across 14 counties, counted inside the 878 boundary — a county split between codes contributes only its part.

Caller ID is easily spoofed, so these figures reflect the number shown on caller ID, not the caller's true location – an area code alone never identifies a caller. The FTC does not verify the facts in these complaints. Source: FTC Do Not Call (DNC) Reported Calls Data, retrieved 2026-08-17.

Frequently Asked Questions about the 878 Area Code
Who called me from a 878 number?
A 878 number is assigned to Pittsburgh, Pennsylvania, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 878 code to look nearby, so a 878 number doesn't prove the caller is local. Recently, 281 unwanted-call complaints were reported to the FTC for numbers showing the 878 code (65% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 878 a scam area code?
No area code is a scam on its own. 878 is a normal, officially assigned code for Pittsburgh, Pennsylvania. Spam callers spoof local codes to raise the odds you answer, so 878 on your caller ID says nothing about who is really calling. Recently, 281 unwanted-call complaints were reported to the FTC for numbers showing the 878 code (65% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 878 area code?
Repeated calls from different 878 numbers are usually spoofing: a robocaller rotates through 878 numbers so each call looks local and slips past simple blocks. Recently, 281 unwanted-call complaints were reported to the FTC for numbers showing the 878 code (65% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.
Should I answer an unknown 878 number?
If you aren't expecting a 878 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.
How do I block calls from the 878 area code?
Block a single 878 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 878 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 878?
Area code 878 covers Pittsburgh and the surrounding area in Pennsylvania, spanning 450 cities with about 2,677,445 residents. It shares its area with overlay codes 412, 724.
When did area code 878 go into service?
Area code 878 went into service on August 17, 2001. It was added as an overlay of 412, so 878 numbers serve the same area that 412 already covered.
Is 878 a real area code?
Yes. 878 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Pittsburgh, Pennsylvania. A real code can still show up on spoofed spam calls, so treat unknown 878 calls with normal caution.
What timezone is the 878 area code in?
The 878 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 878 caller may not be in that zone.
How do I call a 878 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 878 and the seven-digit number. From a mobile phone you can usually just enter +1 878 followed by the number and let the phone add the exit code for you.
