All CDLE systems and applications may be experiencing issues and delays due to global internet disruption. Our technical teams are working on resolutions now.
We appreciate your patience, as we work to return systems to normal.


Respond to Job Separations


Employers can respond to job separations in two different ways:

  • Fax the Request for Facts About a Former Employee's Employment: Form UIB-290, to 303-318-9014. For questions about completing the "Request for Facts About a Former Employee's Employment" call 303-318-9055

  • Access MyUI Employer+, an online tool for Employers.

Responding to Unemployment Insurance Claim Documents

Here are a few tips to ensure your UI documents are processed as quickly as possible.

Please DO:

  • Use the online portal to respond to questionnaires, file an appeal, or upload supporting documentation as one complete document when possible, rather than faxing or mailing. If you absolutely must fax a document, please use the fax number listed on the form you are responding to.
  • Return the barcoded CDLE form with any supporting documentation, and put that form on the top! Please do this even when sending your own forms as the barcode tells us which issue the documentation belongs with.
  • Include the Claimant ID number on any pages that are not a barcoded CDLE form.
  • Make sure all pages are in the proper order with the CDLE barcoded form being on top of any supporting documentation for each form, especially when returning multiple forms.
  • If you are unable to return the CDLE  form, include the form’s Document ID on all pages. This can be found at the bottom left corner of the form.
  • Report fraud online by submitting an employer fraud report form.

Please Don't:

  • Include a cover page other than the CDLE barcoded form when submitting documents by fax.
  • Upload one page at a time for multiple page documents (submit as one complete document when possible).
  • Return forms by mail or fax to report fraud.
  • Add two claimants’ info on the same page.
