A worker identification (WID) number, which is person-specific, is generated by the Department of Labor and Industry (DLI) and is used instead of a Social Security number to identify claims.

DLI sends the WID number in the initial electronic data interchange (EDI) First Report of Injury (FROI) acknowledgement report to the insurer/trading partner.

How to obtain WID numbers

Background, new law

DLI assigns a WID number when a first report of injury has been filed with DLI or a case-creating document on the claim has been filed with DLI or the Office of Administrative Hearings (OAH). Legislation effective June 1, 2018, allows attorneys, intervenors, potential intervenors and qualified rehabilitation consultants (QRCs) to obtain the WID number from DLI (Minnesota Statutes § 176.231, subd. 9). Online WID number access is available to attorneys and QRCs only.

Attaining a WID number by phone

Intervenors not represented by an attorney

An intervenor is a person or entity that has already filed a motion to intervene in a pending workers' compensation dispute, either at the Office of Administrative Hearings or DLI. An intervenor who is not represented by an attorney may obtain the WID number in one of two ways.

Option 1. If the dispute is pending at OAH, an intervenor may contact OAH for information about how to look up the dispute and WID number in the C-Track system. OAH has a guide for intervenors at mn.gov/oah/assets/oah-workers-compensation-intervenor-efiling-user-guide_tcm19-339863.pdf.

Option 2. If the dispute is pending at DLI, an intervenor may call the Alternative Dispute Resolution unit at 800-342-5354.

Potential intervenors not represented by an attorney

A potential intervenor is a person or entity that has not yet filed a motion to intervene in a pending workers' compensation dispute, but intends to do so. A potential intervenor that is not represented by an attorney may obtain the WID number in one of two ways.

Option 1. A potential intervenor may obtain the WID number from the attorney who sent notice of the right to intervene.

Option 2. A potential intervenor may file a paper motion to intervene with OAH or DLI (depending upon where the dispute is pending) using the Social Security number (SSN).

Attorneys

An attorney may also call DLI's Copy File Review at 651-284-5200 to request a WID number. Copy File Review will provide the WID number by phone to an attorney with written verification that the person represents the employee, employer or insurer for the employee's date of injury according to the following procedures.

If there is a Notice of Appearance form or retainer agreement already in the division file, the attorney may call Copy File Review and provide the names of the parties, date of injury and SSN (so representation and WID number can be verified). Copy File Review will then be able to provide the attorney the WID number by phone.

If there is no Notice of Appearance form or retainer agreement in the division file, Copy File Review will provide the WID number if the attorney mails or faxes a letter* on the attorney or firm's letterhead, including:

  • a statement that the attorney would like to be called with the WID number;

  • a statement that the attorney represents the injured worker, employer or insurer;

  • the names of the parties, the employee's SSN and the date of injury (so DLI can verify whether there is a WID number); and

  • the attorney’s signature and attorney license number.

Copy File Review will call the attorney with the WID number.

*These attorney letters can be faxed to 651-284-5731 or sent to Minnesota Department of Labor and Industry, Copy File Review, P.O. Box 64226, St. Paul, MN  55155-0226.
