The Surprising History of Oregon’s Phone System

Originally, 503 covered all of Oregon – from Portland to the eastern desert. As the population exploded (especially around Portland), regulators had to get creative with geographic splits and new area code assignments.

• 2008: 971 expands to cover all 503 territory

• 2010: 458 overlays 541 (central/western Oregon)
