Uniform assigned names for claims administrators’ representatives’ offices and lien claimants

Forms filed in the Electronic Adjudication Management System (EAMS) automatically create new workers’ compensation case files or open existing case files. Part of this automated process involves associating the related parties to their cases. To ensure that parties are properly associated to cases in EAMS, a uniform naming convention was created for claims administrators and representatives by the DWC. Claims administrators are insurance carriers who self-administer claims, third party administrators, and self-insured self-administered employers. Representatives are attorney and non-attorney representatives. Lien claimants are parties, usually service providers, requesting payment of money owed in a workers’ compensation case.

Uniform names for claims administrators’ offices and representatives’ offices are assigned by the DWC.

Anyone filing a form in EAMS—be they an injured worker, a claims administrator, an attorney, a lien claimant or other—must use the uniform assigned name to identify the claims administrator or representative in the case for which they are filing. The other case parties do not currently have uniform assigned names.

The naming convention

Claims administrators’ offices are assigned a name for each office, not a name for each entity for which claims are administered. To fit within the available space, names have been abbreviated. Law firm names include no more than the first two principals’ last names. Sole practitioners are listed by their first name and then last name, unless they use only their last name as their trade name, or always use their first initial.

Each uniform name in EAMS is a combination of the name of the office and the city in which the office is physically located. Example: ACCELERATED CLAIMS IRVINE

Uniform names have no punctuation or special characters, only capital letters A through Z and spaces. The city is where the office is physically located if known, which may differ from the mailing address, especially for electronic operations.

Address standardization is in accordance with United States Postal Service (USPS) standards.

In the unlikely event there is more than one office with the same name located in the same city, the street name, which typically corresponds to the office’s physical address, is inserted between the name and the city portions of the uniform name. Example: COUNTY COUNSEL FIGUEROA LOS ANGELES and COUNTY COUNSEL TEMPLE LOS ANGELES

If the case of claims’ administrators where there is more than one post office box for a specific location, the P.O. box number is inserted between the name and city to identify the segregation of cases. Example: GALLAGHER BASSETT 254917 SACRAMENTO and GALLAGHER BASSETT 255397 SACRAMENTO

Using assigned uniform names (UAN) on your forms

A name entered in a claims administrator or representative name field of an EAMS form must exactly match a name on the applicable list of uniform names for EAMS to process the form.

The legal name of the entity responsible for the claim is captured in EAMS in the insurance company fields of EAMS forms, which also have a claims administrator field. On such forms, enter the legal name, and address if known, of the entity responsible for the claim in the insurance company field, and the name of the claims administrator’s office in the claims administrator field. On forms which have only one field labeled either insurance company or claims administrator, enter the uniform name for the claims administrator’s office.

To put it another way, if there are two fields, the insurance company field gets the legal name of the responsible entity and the claims administrator field gets the claims administrator’s office name. If there is only one field, regardless of whether the field is called insurance company or claims administrator, it gets the claims administrator’s office name.

NOTE: When identifying the State Compensation Insurance Fund on forms, use the UAN in both the “insurance carrier” and “claims administrator” fields.

Changing or adding a name to the database

Before EAMS go-live, DWC pre-registered approximately 300 claims administrators’ offices and 1,400 representatives’ offices, accounting for approximately 80 percent of current case volume. Claims administrators’ offices, representatives’ offices and lien claimants which are not pre-registered must promptly register with the DWC Central Registration Unit (CRU) to obtain uniform names to file forms in EAMS.

Additionally, new offices and changes of name, location, mailing address, telephone, e-mail, fax, or preferred method of service must be registered with the CRU. Registration requests are submitted on letterhead with an authorized signature by e-mail to The new assigned name or information will be posted within 10 business days of receipt of the request.

Requests for new office names or name changes must conform to the naming convention.

At this time the CRU is registering only claims administrators’ offices, representatives’ offices and lien claimants . Other types of case participants must notify the district office of changes of name, mailing address, or telephone number. All case participants must also notify all other case participants of any change of name, mailing address, or telephone number.

Preferred method of service

The preferred method of service a participant designates in EAMS is for service of documents on the participant by DWC. If a participant does not designate a preferred method of service, or if the participant is not being registered by the CRU, DWC will serve that participant by U.S. mail. However, participants may agree among themselves to accept service from each other in a manner other than by U.S. mail.

UEBTF (Uninsured Employers Benefit Trust Fund) and SIBTF (Subsequent Injuries Benefit Trust Fund) offices are not included in the list of claims administrators' offices because those offices are associated with a case by properly obtaining jurisdiction, not simply by entering their name on an EAMS form. In fact, EAMS will not process forms if those office names are entered in the insurance company or claims administrator fields. However, for ease of reference, the EAMS reference numbers (ERN), names, addresses, and telephone numbers of those offices are as follows. Please use only these when entering UEBTF or SIBTF as a case participant.
