Collection Agency

Any business involved in collecting a debt on behalf of a debt owner, or collecting a debt you have purchased from another person ('debt buyer,' see definition), and either you, the debtor, or the debt owner are located in Washington, you must have a Collection Agency endorsement and be licensed in Washington.

Note: The law clarifies that collection agency licensees are prohibited from engaging in the unauthorized practice of law. See Department of Licensing for more information.

  • You cannot begin business activity until you receive a business license listing the required endorsement.
  • Washington is a closed-border state. You must have a license before contacting debtors or soliciting clients in Washington.
