LLC Review Desk's 2026 picks for foreign registration services in Oregon, favorite first, are Mainstay Filing ($199), Oregon Registered Agent.co ($199) and OR Registered Agent.org ($199). Mainstay Filing is our favorite, because $199 gets the Oregon registration filed, year one as registered agent costs nothing, and after that it's $149 a year.

Our score
9.6out of 10
9.6 out of 10
Our favorite is Mainstay Filing, because it's $199 beyond the state fee in any state, and the first registered agent year is included.
From year two the agent plan is $149 a year, and it's the same price everywhere.
Over three years it costs $100 more than Oregon Registered Agent.co, and for us the extra things it handles are worth that.

We took each price from the company's own pages on November 12, 2026. On top of every row, Oregon charges a $275 registration fee, which isn't in these totals.
How the order came together
Two things count most to us, three-year cost and filings in the price, at 29% each. Renewal price, state fit and up-front totals share 42%, and Oregon came down to filings in the price.
Registering in a second state means working with two states, so one company at one price for both won the coverage score over Oregon Registered Agent.co.
