Quick answer
503 is the original 1947 Portland code and carries the most prestige, but clean numbers are scarce. 971 is the 2000 overlay covering the same area — less status, but far easier to get. Both require 10-digit dialing and are equally local. Pick 503 for prestige, 971 for availability.

When to choose 503
Choose 503 when Oregon prestige matters — a legacy Portland business, a brand that markets its number, or anyone who wants the recognizable original code. Assigned in 1947, 503 is now heavily used, so clean or memorable 503 numbers are limited and the best patterns go fast.
When 971 is the smart pick
Choose 971 when you want a genuine Portland number without hunting for scarce inventory. Introduced in 2000 as the overlay on 503, 971 covers the identical Portland metro and northwest Oregon, and reads as fully local. For most new businesses it is the practical choice — same area, easier to get a clean number.
Why there are two codes for Portland
503 and 971 are overlay codes: two area codes stacked on the same region. Oregon added 971 in 2000 because 503 was running out of numbers — 503 now has roughly 99% of its central-office prefixes assigned. Overlays add numbering capacity without making existing 503 holders renumber — which is why every Portland-area call now uses 10-digit dialing.

503 vs 971 — FAQ
Is 503 better than 971?
Neither is objectively "better" — they cover the same Portland and northwest Oregon geography. 503 carries more prestige as the original 1947 code, while 971 (2000) is the newer overlay that is easier to obtain. Choose 503 for status, 971 for availability.
Can I still get a 503 number?
503 is heavily assigned, so clean or vanity 503 numbers are scarce and the best patterns go quickly. 971 has more available inventory because it is the newer overlay. With DialPhone you can search both and pick whichever has the number you want.
Are 503 and 971 the same place?
Yes. 503 and 971 are overlay codes serving the identical Portland metro and northwest Oregon area. A 971 number is just as local to Portland as a 503 number; the difference is age and prestige, not location.
Do I dial 503 and 971 numbers differently?
No. Because 971 overlays 503, all Portland-area calls require 10-digit dialing (area code + 7-digit number) regardless of which code you have. From anywhere in the US or Canada you dial 1 + the area code + the number.
