Feature Answer

What is Area Code 503?

Area code 503 is a North American telephone area code assigned to Portland, Oregon, and the surrounding Willamette Valley. First assigned in 1947 as one of the original 86 area codes in the North American Numbering Plan, 503 is among the oldest area codes in the country. It serves Portland, Beaverton, Hillsboro, Gresham, Salem, and the rest of northwestern Oregon, and is a local (non-toll-free) area code in the Pacific Time Zone.

503 originally covered all of Oregon. The 1995 split (541) carved out southern, central, and eastern Oregon, leaving 503 with just the Portland metro and Willamette Valley. Continued growth led to overlay 971 being added in 2000 — the first area code overlay on the West Coast. Despite the overlay, a 503 number remains the heritage signal for established Portland creative agencies, breweries, outdoor brands, and the city's many small businesses.

WHY LOCALS PICK UP

Why aren't 503 numbers enough on their own?

Spam filters don't distinguish between scam calls and unknown legitimate ones. Portland customers pick up a verified 503 line 3.3x more often than an unverified one because the caller ID looks like a real business.
