SIDES E-Response Login
Respond Electronically to UI Forms
State Information Data Exchange System (SIDES) and SIDES E-Response are two
web-based options developed through a partnership between the U.S. Department of
Labor (DOL) and state Unemployment Insurance (UI) agencies to simplify and
streamline responses to UI information requests. Both SIDES and SIDES E-Response
use nationally standardized, electronic formats to process UI information
exchanges. View an introductory video from
Employers may reply to the following forms online using the
SIDES E-Response website:
- UCB-16 - Separation Notice
- UCF-350-4 - Weekly Earnings Audit
- UCF-17275 - Weekly Earnings Audit
- UCF-17275-2 - Weekly Earnings Audit NDNH
- UCF-17275-3 - Weekly Earnings Audit SDNH
The website is accessible free of charge to any employer or
third-party administrator (TPA) with Internet access.
SIDES E-Response provides a nationally-standardized format, in which employers
and TPAs can easily respond to UI information requests, attach documentation
for separation information, and receive a date-stamped confirmation of receipt.
Employers and TPAs that use SIDES E-Response are able to better anticipate and
supply the data needed for UI information requests and in return, reduce
follow-up phone calls and paper work, prevent improper payments, and streamline
UI response processes, ultimately saving time and money. Given the sensitive
data exchanged between state UI agencies and employers and TPAs, SIDES has
multiple layers of security and uses secure communication protocols.
How it Works
SIDES E-Response is a free website through which employers and TPAs may submit
responses to the forms listed above.
Employers and TPAs will receive the paper form by mail from Wisconsin’s Unemployment insurance Division. The
form will include an access code that permits the employer or TPA to log in to
SIDES E-Response and enter the requested information in a standardized format.
SIDES E-Response Tips and Assistance
Logging in to the SIDES E-Response Website
- Login at https://uisides.org
- Use ALL CAPITAL letters when logging in.
- On the first page, select “Separation Information” or “Earnings Verification,” depending on the form. Any other options
are not yet available.
- For separation notices, check that you are entering the Federal Employer Account Number
(FEIN) associated with the Wisconsin UI account printed on the UCB-16
- For separation notices, check the Wisconsin UI account number (SEIN). If the SEIN printed on the
UCB-16 shows alphabetical letters after the numbers, then login by entering
the 6 numbers, followed by a space, followed by the 2 CAPITAL letters. Use
ALL CAPITAL letters (example: “123456 AA”).
- Check the access code. Use ALL CAPITAL letters if the access code
contains any letters.
- Check the mail date of the form. If the most recent form has a
date sent over 30 days old, then there are no information requests available
and you will be unable to login.
- NOTE: you will be locked out and unable to login to the E-Response
website for one hour after 3 consecutive login errors within a 24 hour
period, though the same login error message continues to display.
- Access codes cannot be changed by the employer. Login information is
determined by the system that generates the forms. There is no method
currently for the employer to change an access code.
- Access codes must be entered using ALL CAPITAL letters (if any letters
appear in the access code).
- There is one access code assigned for each form. Any
access code is good for 30 days and allows the employer to respond to all
pending requests. However, requests remain on the SIDES E-Response site for
only 30 calendar days. Responses are timely if completed before the
date due (7 days from date sent).
- For separation notices only, employers with valid Wisconsin UI accounts will receive an access code
and can use SIDES E-Response. Employers receiving the UCB-16 and who have no
valid Wisconsin UI account number will not receive an E-Response Access

SIDES differs from SIDES E-Response in that it is an integrated
computer-to-computer interface, not a website. SIDES is designed for employers
and TPAs that typically deal with a large volume of UI information requests.
SIDES is especially helpful to those employers and TPAs that operate in multiple
SIDES is available free of charge, although there will be internal IT system
development costs to integrate with SIDES.
