Area Code for Portland, Oregon
Portland, Oregon uses area codes 503 (since 1947) and 971 (overlay since 2000). Full guide to coverage, history, scams, and getting a local business number.
Portland, Oregon runs on two area codes — 503 (original, 1947) and 971 (overlay, 2000) — covering the city and its metro from the Pearl District to the Silicon Forest in Hillsboro.
This guide is specifically for Portland, Oregon. If you landed here looking for Portland, Maine, that city uses area code 207 — a completely different NANP assignment in the Eastern time zone. Everything below covers Oregon’s largest city.
What’s the area code for Portland, Oregon?
Portland, OR is served by two overlapping area codes under the North American Numbering Plan:
| Code | Established | Coverage | Notes |
|---|---|---|---|
| 503 | January 1, 1947 | Portland metro, Salem, Astoria, Beaverton, Hillsboro | Original Oregon code; most recognized Portland identifier |
| 971 | October 1, 2000 | Same as 503 (full overlay as of Apr 27, 2008) | Introduced to relieve 503 number exhaustion; 10-digit dialing required |
Both codes share the same time zone: Pacific Time (PT), UTC−8 in winter and UTC−7 in summer.
The 10-county service area covered by both codes includes: Clackamas, Clatsop, Columbia, Marion, Multnomah, Polk, Tillamook, Washington, and Yamhill counties, plus the northern portion of Linn County.
Portland metro area codes by region
Downtown Portland and inner neighborhoods
The Portland city core — Downtown, the Pearl District, Old Town Chinatown, Lloyd District, and the inner eastside neighborhoods like Hawthorne and the Central Eastside — all fall within the 503/971 overlay.
Key Portland neighborhoods and their area code context:
- Downtown / Pearl District — 503/971; concentration of tech companies, ad agencies, law firms
- Hawthorne / Division — 503/971; independent retail, restaurants, medical practices
- Alberta Arts District / NE Portland — 503/971; neighborhood businesses, galleries, breweries
- NW Portland / Nob Hill — 503/971; boutiques, restaurants, residential
- SE Portland — 503/971; Powell’s Books, Stumptown Coffee origin location, craft breweries
Portland suburbs: Beaverton and Hillsboro (the Silicon Forest)
Beaverton and Hillsboro sit immediately west of Portland in Washington County, still within the 503/971 overlay.
These suburbs are home to Oregon’s technology corridor — Nike’s world headquarters sits in Beaverton, and Intel operates its largest US semiconductor campus in Hillsboro. The name “Silicon Forest” reflects the region’s outsized role in semiconductor and tech manufacturing, analogous to Silicon Valley but deeply rooted in Pacific Northwest industry.
Vancouver, Washington
Vancouver, WA lies directly across the Columbia River and is functionally part of the Portland metro area — sharing commuters, employers, and a regional economy. However, Vancouver uses area code 360 (Washington state), not 503 or 971.
Businesses and residents operating on both sides of the river commonly hold both 503/971 and 360 numbers. A 360 number does not indicate a Portland business.
History of Portland area codes
Oregon’s area code story is one of the longest single-code runs in NANP history — followed by rapid expansion.
1947 — 503 covers all of Oregon. AT&T engineers designed the NANP with 503 assigned to the entire state of Oregon. At the time, low telephone density across a large, sparsely populated state meant a single code sufficed. Oregon held this single-code status for 48 years — an unusual distinction among US states.
November 5, 1995 — 541 splits off. Population growth in the Willamette Valley and mounting demand from fax machines, pagers, and early internet dial-up exhausted 503’s capacity. The Oregon Public Utility Commission (Oregon PUC) ordered a geographic split. Area code 541 was assigned to eastern and southern Oregon — Eugene, Bend, Medford, Corvallis, and the high desert — reducing 503 to the northwest corner of the state.
1999–2000 — 971 overlay introduced. Even after the 541 split, the Portland-concentrated 503 was consuming new numbers rapidly. Rather than split Portland geographically, the Oregon PUC chose an overlay. Area code 971 launched July 1, 1999 for most of the 503 service area (initially excluding Clatsop and Tillamook counties). Mandatory 10-digit dialing took effect January 30, 2000.
April 27, 2008 — Overlay complete. Clatsop and Tillamook counties were added to the 971 overlay, completing the current configuration. All of 503’s territory is now also covered by 971.
February 10, 2010 — 458 overlays 541. Eastern and southern Oregon’s 541 code received its own overlay (458), completing Oregon’s current four-code system: 503, 971, 541, 458.
503 as Portland identity
Area code 503 carries cultural weight in Portland that goes beyond a telephone prefix.
The Keep Portland Weird ethos. Portland’s civic identity — independent, locally-owned, anti-corporate — attaches itself to 503 as a symbol of authenticity. A 503 number signals you are local, not a national chain pretending to be.
The Silicon Forest anchors. Nike’s world headquarters at One Bowerman Drive in Beaverton holds 503 numbers — the brand is Oregon-born and Oregon-headquartered. Intel’s Ronler Acres campus in Hillsboro employs tens of thousands under 503 numbers. These aren’t satellite offices; they are the primary corporate homes of two of America’s most recognizable companies.
Cultural institutions. Powell’s Books — the iconic City of Books on NW 10th Avenue — operates on 503. Stumptown Coffee Roasters, the craft coffee pioneer that launched the third-wave coffee movement, originated in Portland with 503 numbers. The Decemberists, one of the defining indie bands of the 2000s, formed in Portland.
Craft beer capital. Portland consistently ranks as one of the top craft beer cities in the world. Over 70 breweries operate within the Portland city limits, nearly all with 503 or 971 numbers. The city’s brewing culture — from Deschutes’ Portland outpost to Hopworks Urban Brewery — is embedded in the 503 identity.
Portland area code spam and scams
Oregon-specific scams disproportionately target 503 and 971 numbers, exploiting local caller ID trust.
The numbers. Portland’s two area codes generated 48,926 combined FTC complaints as of 2026, representing 52.2% of Oregon’s total scam volume. Area code 503 alone accounted for 31,297 complaints, ranked #153 nationally — with 80.3% in-state targeting, making it what researchers classify as a “pure local-targeting code.”
Common Portland-specific scam patterns:
- PGE (Portland General Electric) impersonation — Callers claim your power will be shut off within hours unless you pay by gift card or wire transfer. PGE will never demand immediate phone payment; 503 energy/solar scams generated 968 FTC complaints in the most recent reporting period.
- IRS arrest threats — Spoofed 503 numbers claim you owe back taxes and will be arrested unless you pay immediately. The IRS never initiates contact by phone; see FCC guidance on spoofing.
- Fake Amazon delivery scams — Callers impersonate Amazon customer service claiming a delivery problem requires account verification or payment. Portland’s high Amazon delivery volume makes this locally effective.
- Tech support scams targeting older residents — Fake Microsoft or Apple “technicians” call 503/971 numbers claiming your computer has been hacked and require remote access or gift card payment.
STIR/SHAKEN and what it means for your calls. STIR/SHAKEN (Secure Telephone Identity Revisited / Signature-based Handling of Asserted information using toKENs) is the FCC-mandated framework that authenticates outbound calls. Carriers assign an attestation level: A (fully verified origin), B (partial), or C (gateway/unverified).
Spoofed scam calls receive C-attestation or none, triggering “Spam Likely” on modern smartphones. When you get a Portland 503 or 971 number through DialPhone, outbound calls carry A-attestation — the highest STIR/SHAKEN trust level — so your calls reach customers as verified. For details on the authentication framework, see our STIR/SHAKEN glossary entry.
How to get a Portland business phone number
Getting a Portland 503 or 971 number for your business takes under 10 minutes through a cloud VoIP provider. No Portland office required.
Step 1: Choose your area code. Both 503 and 971 are valid Portland numbers. Area code 503 carries more established brand recognition; 971 is functionally equivalent. Check availability for your preferred code during signup.
Step 2: Sign up with a VoIP provider. DialPhone lets you search available Portland numbers by area code. See DialPhone pricing for plan details.
Step 3: Assign the number to users or a team queue. Route the Portland number to your mobile, desktop app, or a shared team queue. Add a voicemail greeting, call menu, or AI receptionist to handle calls professionally from day one.
Step 4: Configure outbound caller ID. Set your Portland 503 or 971 number as the outbound caller ID so calls you make display the local number — not an 800 number or your personal cell.
Step 5: Port your existing number if needed. If you already have a Portland number with another carrier, bring it to DialPhone through number porting (typically 2–5 business days for US local numbers). See our number porting guide for the full walkthrough.

Portland area code FAQ
Portland area code FAQ
What is the area code for Portland, Oregon?
Portland, Oregon is served by two area codes: 503 and 971. Area code 503 is the original code, dating to 1947, and covers Portland plus the surrounding metro — Beaverton, Hillsboro, Salem, and Gresham.
Area code 971 is an overlay introduced in 2000 that covers the exact same geography. New numbers assigned in the Portland metro today are often 971. Both codes require 10-digit dialing for all calls, including local ones.
Note: Portland, Maine uses area code 207 — a completely separate NANP assignment with no connection to Oregon.
Does Portland Oregon have one area code or two?
Portland, Oregon has two area codes: 503 and 971. They cover the same geographic territory — an overlay arrangement. There is no geographic split between them; a 503 number and a 971 number can both belong to addresses on the same Portland street.
The overlay was created because the 503 number pool was nearing exhaustion after the 1995 split that gave eastern Oregon its own code (541). Rather than splitting Portland again, regulators introduced 971 as a second pool over the same area.
What is the difference between 503 and 971?
503 and 971 cover the same northwest Oregon geography — Portland, Salem, Beaverton, Hillsboro, and surrounding communities. The practical difference is age and cultural weight.
Area code 503 is the original code (1947) and carries established business identity. Nike, Intel, Columbia Sportswear, and Adidas North America all have 503 numbers. Area code 971 was introduced in 2000 as an overlay when 503 numbers ran low. Newer businesses and mobile subscribers are more likely to hold 971 numbers. Neither code is superior; both are fully valid Portland numbers.
What area codes cover the rest of Oregon?
Outside the Portland and Salem metro, Oregon uses two additional area codes. Area code 541 was created November 5, 1995, when it split from 503 to cover eastern and southern Oregon — Eugene, Bend, Medford, Corvallis, Ashland, Pendleton, and the entire eastern half of the state.
Area code 458 was added February 10, 2010 as an overlay for 541, covering the same eastern and southern Oregon geography. Oregon's four area codes in total are: 503, 971 (northwest), 541, and 458 (rest of state).
Is Vancouver, Washington part of the Portland area code?
No. Vancouver, Washington — directly across the Columbia River from Portland — uses area code 360, not 503 or 971. Washington state has its own NANP assignments separate from Oregon.
The Portland metro area functionally spans both sides of the river, so it is common to see Oregon 503/971 numbers and Washington 360 numbers used side by side by businesses operating in the greater Portland region. If you call a Vancouver, WA business and see a 360 number, that is normal — it is not a Portland code.
Are 503 or 971 calls spam?
Not inherently. Legitimate Portland businesses hold 503 and 971 numbers. The problem is caller ID spoofing — scammers fake a local 503 or 971 number to increase answer rates. Portland metro area codes generated 48,926 FTC complaints in 2026, representing 52.2% of Oregon's total scam volume.
Legitimate carriers implement STIR/SHAKEN caller authentication. When you get a Portland number through DialPhone, outbound calls carry A-attestation — the highest STIR/SHAKEN trust level — so recipients see a verified caller ID rather than 'Spam Likely.' If you receive a 503 call threatening utility shutoff, IRS arrest, or fake Amazon delivery issues, that is almost certainly a spoofed scam.
Can I get a Portland 503 or 971 number without a Portland office?
Yes. Virtual VoIP phone numbers are not tied to a physical address. A business anywhere in the US can get a Portland 503 or 971 number through a cloud phone provider and route calls to any device — mobile, desktop app, or team queue.
DialPhone assigns available Portland numbers in minutes. No Portland office, no hardware, no long-term contract required. Outbound calls display your Portland number as caller ID, and inbound calls ring wherever your team is located.
How long does it take to port an existing 503 or 971 number?
US local number porting typically takes 2 to 5 business days when all information matches the losing carrier's records exactly. The key requirement is that the account name, address, and billing telephone number (BTN) on your porting request match what the current carrier has on file.
DialPhone's porting team handles the LOA submission and carrier coordination. Your number stays active on the old carrier until the port completes — there is no gap in service. See our number porting guide for the full step-by-step process.
Get a Portland business number
A verified Portland 503 or 971 number builds instant local trust — whether you’re expanding into the Oregon market or a Portland-based business that wants its calls answered rather than screened as spam.
DialPhone provides Portland numbers with STIR/SHAKEN A-attestation, AI receptionist, call recording, and SMS — all on a single plan with no hardware.
