State Information Data Exchange System (SIDES)

The State Information Data Exchange System (SIDES) is a safe and fast way for employers and Third-Party Administrators (TPAs) to get and respond to a Notice of Unemployment Insurance Claim Filed (DE 1101CZ) (PDF) online.

When a new Unemployment Insurance claim is filed, or when an existing claim is reopened, we send a Notice of Unemployment Insurance Claim Filed (DE 1101CZ) to employers. Employers provide information about why the person is no longer working for them. This helps determine if the person qualifies for benefits and makes sure the employer’s unemployment insurance reserve account is charged correctly.
