Oregon was assigned a single area code in 1947: 503, covering the entire state. For 48 years the single code carried Portland, the Willamette Valley, the coast and eastern Oregon — one of the longest single-code runs in the western US.
541 split from 503 in 1995 for everywhere outside the Willamette Valley (Eugene, Bend, Medford, Salem at first, Klamath Falls, Pendleton), leaving 503 with Portland, Salem and the Willamette Valley north of Eugene.
Overlays followed: 971 was added in 2000 over 503 for the growing Portland metro, and 458 in 2010 over 541 for the rest of the state. Oregon notably runs just 4 area codes — fewer than any West Coast state — reflecting its dispersed but relatively low population density.
Oregon went 48 years on a single area code (503) — one of the longest single-code runs for a state with a major metro. By the time 541 was finally added in 1995, the original 503 had carried Oregon through the entire post-war boom, the rise of Nike, the lumber industry collapse and Portland's pre-tech cultural emergence.
