eFiling Tips: Using the Correct File Number

The Iowa Division of Workers' Compensation (DWC) requires electronic filing (eFiling) on the Workers' Compensation Electronic System (WCES).

When eFiling on WCES, you must use the correct file number. If you fail to use the correct file number, DWC may reject your document.

This page contains tips for using the correct file number when eFiling on WCES.

Use the correct FROI number when Efiling a Petition to initiate a new case on WCES.

WCES allows you to search for an existing case before eFiling a petition to initiate a new case on WCES. You should search by the claimant's name and last four digits of Social Security Number to search for FROIs filed before July 22, 2019, because DWC did not track employee date of birth in its pre-WCES case manager system (CMS). You may also search by the claimant's name, date of birth, and last four digits of Social Security Number if the FROI was filed on or after July 22, 2019, because WCES allows the DWC CMS to track employee date of birth from those FROIs.

The WCES tutorial video, "Filing a New Case," and WCES User Guide show you how to check case information on WCES.

The correct file number will depend on when the FROI was filed as well as if and when any other petitions were filed relating to the injury in the FROI:

  • If no other petition has been filed relating to the injury in the FROI, eFile a petition to initiate a new case on WCES using the FROI number (e.g., 1699999, 19999999, 20999999).
  • If a petition was filed relating to the injury in the FROI before WCES went live, eFile a petition to initiate a new case on WCES using the pre-WCES litigation file number (e.g., 5999990).

Most commonly, this applies to documents such as:  

  • Original Notice & Petition (Form 100)
  • Original Notice & Petition Concerning Independent Medical Examination (Form 100A)
  • Original Notice & Petition Concerning Vocational Rehabilitation Program Benefit (Form 100B)
  • Original Notice & Petition Concerning Application for Alternate Care (Form 100C)

If you fail to use the correct file number when eFiling a petition on WCES, DWC may reject your filing.

Check the Case information on WCES Before eFiling Your document on WCES.

Log in on WCES and check the case information before eFiling your document on WCES. This will help you to make sure that you eFile your document under the correct file number on WCES.

If a petition has been filed relating to the injury in the FROI and you are filing a document as part of the contested case proceeding initiated by that petition, eFile your document to an existing case on WCES using the correct WCES file number (e.g., 16999999.01, 19999999.02, 20999999.03).

Most commonly, this applies to documents such as: 

  • Answers
  • Amendments to pleadings
  • Appearances
  • Motions
  • Pre-hearing filings
  • Post-hearing filings
  • Settlement documents

If you fail to use the correct file number when eFiling a document to an existing case on WCES, DWC may reject your filing.

Make sure the file number on your document matches the WCES file number.

The file number you put in the upper right of the caption on your document should match the file number in the WCES case information.

If the file number on your document does match the WCES file number, DWC may reject your filing.

If a petition has been filed relating to the injury in the FROI and you are filing a document as part of the contested case proceeding initiated by that petition, eFile your document to an existing case on WCES using the correct WCES file number (e.g., 16999999.01, 19999999.02, 20999999.03). 

Most commonly, this applies to documents such as: 

  • Answers
  • Amendments to pleadings
  • Appearances
  • Motions
  • Pre-hearing filings
  • Post-hearing filings
  • Settlement documents

If you fail to use the correct file number when eFiling a document to an existing case on WCES, DWC may reject your filing.

Make sure you eFile Your document under the correct WCES file number.

If you eFile your document on WCES under a file number that differs from the file number on your document, DWC may reject your filing.
