How to Participate in SIDES Web Service

Follow the steps below to participate in SIDES Web Service. For complete instructions on how to participate in SIDES Web Service, view the Employment Development Department’s (EDD) SIDES Web Service Users Guide or visit National UI SIDES.

Step 1: File a Power of Attorney with the EDD

Before a Third Party Administrator (TPA) can participate in SIDES Web Service, they must be registered as a counseling service agent with the EDD and have a current Power of Attorney Declaration on file with the EDD for each of the businesses they represent.

For more information, review the Counseling Service Agent Information Sheet (DE 231CSA).

Note: This step is not required for employers.

Step 2: Sign a Participation Agreement with NASWA

You will need to complete a participation agreement and obtain a broker ID by contacting the National Association of State Workforce Agencies (NASWA).

Step 3: Participate in SIDES Web Service with the EDD

Once you have completed your participation agreement with NASWA, the EDD and NASWA will contact you to finalize your SIDES Web Service participation.

Step 4: Perform System Testing

In order to use SIDES Web Service, you must complete two rounds of testing. The first round is SIDES certification testing to validate that your connector can communicate with the national SIDES Broker. The second round of testing is end-to-end testing with the EDD to ensure that you are able to connect to the national SIDES Broker, receive your email notifications, and retrieve and respond to requests for information.

Step 5: Start Using SIDES Web Service

You have now successfully completed all the necessary steps to participate in SIDES Web Service. Participating in SIDES will reduce but not eliminate the paper DE 1101CZ notices. If you receive a paper Notice of Unemployment Insurance Claim Filed (DE 1101CZ or DE 1101ER), continue to complete and mail the paper form within 10 days from the mail date.

Keep Your Client List Up-to-Date

It is your responsibility to keep your client list up-to-date with the EDD to continue receiving the benefits of SIDES Web Service. If the EDD cannot determine your relationship with the client, the client will receive a paper Notice of Unemployment Insurance Claim Filed (DE 1101CZ).
