City population is shown in full. The share of each city inside 210 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 210 cover?

2,036,587 residents across 4 counties, counted inside the 210 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 210 Area Code

Who called me from a 210 number?

A 210 number is assigned to San Antonio, Texas, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 210 code to look nearby, so a 210 number doesn't prove the caller is local. Recently, 2,070 unwanted-call complaints were reported to the FTC for numbers showing the 210 code (60% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 210 a scam area code?

No area code is a scam on its own. 210 is a normal, officially assigned code for San Antonio, Texas. Spam callers spoof local codes to raise the odds you answer, so 210 on your caller ID says nothing about who is really calling. Recently, 2,070 unwanted-call complaints were reported to the FTC for numbers showing the 210 code (60% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 210 area code?

Repeated calls from different 210 numbers are usually spoofing: a robocaller rotates through 210 numbers so each call looks local and slips past simple blocks. Recently, 2,070 unwanted-call complaints were reported to the FTC for numbers showing the 210 code (60% 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 210 number?

If you aren't expecting a 210 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 210 area code?

Block a single 210 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 210 code also stops legitimate local calls, so use it only as a last resort.

Where is area code 210?

Area code 210 covers San Antonio and the surrounding area in Texas, spanning 33 cities with about 2,036,587 residents. It shares its area with overlay code 726.

When did area code 210 go into service?

Area code 210 went into service on November 1, 1992. It was split off from area code 512.

Is 210 a real area code?

Yes. 210 is an active code in the North American Numbering Plan, assigned by NANPA and in service for San Antonio, Texas. A real code can still show up on spoofed spam calls, so treat unknown 210 calls with normal caution.

What timezone is the 210 area code in?

The 210 area code is in the Central Time (CT). Because a number can be kept when someone moves or switches to VoIP, a specific 210 caller may not be in that zone.

How do I call a 210 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 210 and the seven-digit number. From a mobile phone you can usually just enter +1 210 followed by the number and let the phone add the exit code for you.
