City population is shown in full. The share of each city inside 947 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 947 cover?

1,340,164 residents across 5 counties, counted inside the 947 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 947 Area Code

Who called me from a 947 number?

A 947 number is assigned to Troy, Michigan, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 947 code to look nearby, so a 947 number doesn't prove the caller is local. Recently, 234 unwanted-call complaints were reported to the FTC for numbers showing the 947 code (66% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 947 a scam area code?

No area code is a scam on its own. 947 is a normal, officially assigned code for Troy, Michigan. Spam callers spoof local codes to raise the odds you answer, so 947 on your caller ID says nothing about who is really calling. Recently, 234 unwanted-call complaints were reported to the FTC for numbers showing the 947 code (66% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 947 area code?

Repeated calls from different 947 numbers are usually spoofing: a robocaller rotates through 947 numbers so each call looks local and slips past simple blocks. Recently, 234 unwanted-call complaints were reported to the FTC for numbers showing the 947 code (66% 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 947 number?

If you aren't expecting a 947 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 947 area code?

Block a single 947 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 947 code also stops legitimate local calls, so use it only as a last resort.

Where is area code 947?

Area code 947 covers Troy and the surrounding area in Michigan, spanning 41 cities with about 1,340,164 residents. It shares its area with overlay code 248.

When did area code 947 go into service?

Area code 947 went into service on September 7, 2002. It was added as an overlay of 248, so 947 numbers serve the same area that 248 already covered.

Is 947 a real area code?

Yes. 947 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Troy, Michigan. A real code can still show up on spoofed spam calls, so treat unknown 947 calls with normal caution.

What timezone is the 947 area code in?

The 947 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 947 caller may not be in that zone.

How do I call a 947 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 947 and the seven-digit number. From a mobile phone you can usually just enter +1 947 followed by the number and let the phone add the exit code for you.
