Opening an account for a customer? A dated record report ($19) — or a whole list checked.

What this is

Anyone doing business in Seattle holds a business license tax certificate. The City publishes the active ones, with the legal name, the trade name, the NAICS activity and the start date. This site keeps the companies — names that carry Inc, LLC, Corp and the like — and makes them searchable by name, type and place.

Who uses it

• Suppliers and landlords — is this company in the Seattle file, and since when?
• Sales teams — companies by type and place, and the newest ones.
• Owners — your own record as the source publishes it.

What it is not

Not the City of Seattle, and not a certificate. Individuals and names without a company word are left out. “Active” is the City's status on the file date; it is not proof the business still operates.
