City population is shown in full. The share of each city inside 503 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 503 cover?
2,506,323 residents across 10 counties, counted inside the 503 boundary — a county split between codes contributes only its part.

Frequently Asked Questions about the 503 Area Code
Who called me from a 503 number?
A 503 number is assigned to Portland, Oregon, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 503 code to look nearby, so a 503 number doesn't prove the caller is local. Recently, 1,360 unwanted-call complaints were reported to the FTC for numbers showing the 503 code (58% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.
Is 503 a scam area code?
No area code is a scam on its own. 503 is a normal, officially assigned code for Portland, Oregon. Spam callers spoof local codes to raise the odds you answer, so 503 on your caller ID says nothing about who is really calling. Recently, 1,360 unwanted-call complaints were reported to the FTC for numbers showing the 503 code (58% flagged as robocalls). Judge the call itself, not the area code.
Why do I keep getting calls from the 503 area code?
Repeated calls from different 503 numbers are usually spoofing: a robocaller rotates through 503 numbers so each call looks local and slips past simple blocks. Recently, 1,360 unwanted-call complaints were reported to the FTC for numbers showing the 503 code (58% 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 503 number?
If you aren't expecting a 503 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 503 area code?
Block a single 503 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 503 code also stops legitimate local calls, so use it only as a last resort.
Where is area code 503?
Area code 503 covers Portland and the surrounding area in Oregon, spanning 135 cities with about 2,506,323 residents. It shares its area with overlay code 971.
When did area code 503 go into service?
Area code 503 went into service on January 1, 1947. Overlay code 971 now shares its territory.
Is 503 a real area code?
Yes. 503 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Portland, Oregon. A real code can still show up on spoofed spam calls, so treat unknown 503 calls with normal caution.
What timezone is the 503 area code in?
The 503 area code is in the Pacific Time (PT). Because a number can be kept when someone moves or switches to VoIP, a specific 503 caller may not be in that zone.
How do I call a 503 number from abroad?
From outside the US, dial your country's exit code, then 1 (the US country code), then 503 and the seven-digit number. From a mobile phone you can usually just enter +1 503 followed by the number and let the phone add the exit code for you.
