City population is shown in full. The share of each city inside 835 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 835 cover?

2,721,665 residents across 11 counties, counted inside the 835 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 835 Area Code

Who called me from a 835 number?

A 835 number is assigned to Allentown, Pennsylvania, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 835 code to look nearby, so a 835 number doesn't prove the caller is local. Recently, 208 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (77% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 835 a scam area code?

No area code is a scam on its own. 835 is a normal, officially assigned code for Allentown, Pennsylvania. Spam callers spoof local codes to raise the odds you answer, so 835 on your caller ID says nothing about who is really calling. Recently, 208 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (77% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 835 area code?

Repeated calls from different 835 numbers are usually spoofing: a robocaller rotates through 835 numbers so each call looks local and slips past simple blocks. Recently, 208 unwanted-call complaints were reported to the FTC for numbers showing the 835 code (77% 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 835 number?

If you aren't expecting a 835 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 835 area code?

Block a single 835 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam).
