City population is shown in full. The share of each city inside 573 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 573 cover?

1,181,739 residents across 46 counties, counted inside the 573 boundary — a county split between codes contributes only its part. The 35 largest are listed.

Frequently Asked Questions about the 573 Area Code

Who called me from a 573 number?

A 573 number is assigned to Columbia, Missouri, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 573 code to look nearby, so a 573 number doesn't prove the caller is local. Recently, 956 unwanted-call complaints were reported to the FTC for numbers showing the 573 code (69% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 573 a scam area code?

No area code is a scam on its own. 573 is a normal, officially assigned code for Columbia, Missouri. Spam callers spoof local codes to raise the odds you answer, so 573 on your caller ID says nothing about who is really calling. Recently, 956 unwanted-call complaints were reported to the FTC for numbers showing the 573 code (69% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 573 area code?

Repeated calls from different 573 numbers are usually spoofing: a robocaller rotates through 573 numbers so each call looks local and slips past simple blocks. Recently, 956 unwanted-call complaints were reported to the FTC for numbers showing the 573 code (69% 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 573 number?

If you aren't expecting a 573 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 573 area code?

Block a single 573 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 573 code also stops legitimate local calls, so use it only as a last resort.

Where is area code 573?

Area code 573 covers Columbia and the surrounding area in Missouri, spanning 287 cities with about 1,181,739 residents. It shares its area with overlay code 235.

When did area code 573 go into service?

Area code 573 went into service on January 7, 1996. It was split off from area code 314.

Is 573 a real area code?

Yes. 573 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Columbia, Missouri. A real code can still show up on spoofed spam calls, so treat unknown 573 calls with normal caution.

What timezone is the 573 area code in?

The 573 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 573 caller may not be in that zone.

How do I call a 573 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 573 and the seven-digit number. From a mobile phone you can usually just enter +1 573 followed by the number and let the phone add the exit code for you.
