If $1,500.00 in wages has not yet been paid, or the employer is a domestic or household employer, the online system will tell the employer they are not liable and will have them call Colorado Division of Unemployment Insurance at 303-318-9100. The CO Representative will guide the employer through the steps necessary to begin registration.
Fax/Email/Mail: Entire process will take 15-20 business days from creation of the account to the employer receiving their account number in the mail. Account numbers will not be sent via email even if this is how the department received the registration form.
