How to obtain free credit monitoring and identity theft protection services (updated: 3/4/21)

SAO is making 12 months of free credit monitoring and identity restoration services through Experian available to people whose Social Security numbers may have been exposed in the Accellion incident. Due to privacy laws, we are not able to enroll you directly.

Best practices to protect against identity theft

Review Your Account Statements and Notify Law Enforcement of Suspicious Activity: As a precautionary measure, we recommend that you remain vigilant and review your account statements and credit reports closely. If you detect any suspicious activity on an account, you should promptly notify the financial institution or company with which the account is maintained. You should also promptly report any fraudulent activity or any suspected incidence of identity theft to proper law enforcement authorities, your state attorney general, and/or the Federal Trade Commission (“FTC”).

Copy of Credit Report: You may obtain a free copy of your credit report from each of the three major credit reporting agencies once every 12 months by visiting, calling toll-free 877-322-8228, or by completing an Annual Credit Report Request Form and mailing it to Annual Credit Report Request Service, P.O. Box 105281, Atlanta, GA 30348. You can also contact one of the following three national credit reporting agencies:


P.O. Box 105851

Atlanta, GA 30348



P.O. Box 9532

Allen, TX 75013



P.O. Box 1000

Chester, PA 19016


Fraud Alert: You may want to consider placing a fraud alert on your credit report. An initial fraud alert is free and will stay on your credit file for one year. The alert informs creditors of possible fraudulent activity within your report and requests that the creditor contact you prior to establishing any accounts in your name. To place a fraud alert on your credit report, contact any of the three credit reporting agencies identified above. Additional information is available at

Security Freeze: In the State of Washington and some other states, you have the right to place a security freeze on your credit file. This will prevent new credit from being opened in your name without the use of a PIN that is issued to you when you initiate the freeze. A security freeze is designed to prevent potential creditors from accessing your credit report without your consent. As a result, using a security freeze may interfere with or delay your ability to obtain credit. You must separately place a security freeze on your credit file with each credit reporting agency. There is no fee to place, lift or remove the security freeze. In order to place a security freeze, you may be required to provide the consumer reporting agency with information that identifies you, including your full name, Social Security number, date of birth, current and previous addresses, a copy of your state-issued identification card, and a recent utility bill, bank statement or insurance statement.

Additional Free Resources: You can obtain information from the consumer reporting agencies, the Federal Trade Commission or from your state Attorney General about steps you can take toward preventing identity theft. You may report suspected identity theft to local law enforcement, including to the FTC or to the state Attorney General. Here is the contact information for the FTC:

Federal Trade Commission, 600 Pennsylvania Ave, NW, Washington, DC 20580, and


You also have certain rights under the Fair Credit Reporting Act (FCRA): These rights include knowing what is in your file; disputing incomplete or inaccurate information; and requiring consumer reporting agencies to correct or delete inaccurate, incomplete, or unverifiable information.

Frequently asked questions

What Happened? In mid-January of 2021, SAO was alerted to a potential security incident involving the Accellion file transfer service. SAO immediately contacted Accellion for specific details. Over the next few weeks, SAO learned that an unauthorized person gained access to data stored in SAO’s file transfer account with Accellion. SAO began working with Accellion to identify which files may have been impacted by the incident. The incident is under active investigation by Accellion, SAO, and law enforcement.

What Information Was Involved? Some of the data files identified by Accellion contained personal information of individuals, among others, who received unemployment benefits from the Employment Security Department (“ESD”) in the 2017 to 2020 time period. These files may have contained the person’s name, Social Security number, date of birth, street and email addresses, bank account number and bank routing number. The Accellion service was not managed by ESD and ESD bears no responsibility for this data breach and is not in a position to respond to calls or questions about this matter.

Were Washingtonians targeted? There is absolutely no evidence to date that that the State of Washington or any of its residents were the target of this incident. This incident affected multiple federal and state, local, tribal, and territorial government organizations as well as private industry organizations businesses including those in the medical, legal, telecommunications, finance, higher education, retail, and energy sectors.

Was SAO using an old or outdated product? At the time of the breach, Accellion was supporting and servicing the file transfer platform that SAO and many other organizations were using. In late summer 2020, SAO began the process of migrating to Accellion’s newer platform, Kiteworks, a process that was completed Dec. 31, 2020.

The week of Jan. 25: SAO determined that some of the data in the affected SAO files identified by Accellion contained personal information of people who received unemployment benefits from the Employment Security Department (“ESD”).
