Diversified Adjustment Service (DAS) is a Minnesota-based collection agency that pursues consumer debt on behalf of telecom, utility, and other original creditors. If DAS is contacting you, request debt validation in writing before paying, particularly if the account showed up on your credit report without a notice you recall receiving first.

Yes. DAS has been sued in federal court well over 280 times for alleged FDCPA and related violations, including Nathanson v. Diversified Adjustment Service, Inc. (D. Minn.), part of a long-running pattern of individual and putative class litigation over the company’s calling and notification practices. Common allegations in CFPB complaints and court filings include contacting consumers at their workplace after being told not to — a specific FDCPA violation — and reporting debts to credit bureaus without first sending the required validation notice. If DAS has contacted you at work after you asked them to stop, or reported a debt you never got notice of, document the contact and see credit report dispute for how to challenge an inaccurate tradeline.

Questions & Answers

Is Diversified Adjustment Service a legitimate debt collector?

Diversified Adjustment Service shows up in the CFPB consumer complaint database, which tracks real complaints filed against real companies — so it is a legitimate, registered entity, not a scam name. That doesn't mean every call claiming to be from them is real; scammers impersonate real collectors. Verify what they're collecting before paying anything — see what to do the first time a collector contacts you.

How do I stop Diversified Adjustment Service from calling me?

Under the FDCPA, you can send Diversified Adjustment Service a written cease-and-desist letter and they must stop contacting you except to confirm they've received it or to notify you of specific legal action. This doesn't erase the debt — it only stops the calls. See the cease-and-desist letter glossary entry for how to send one.

Is Diversified Adjustment Service on my credit report?

If Diversified Adjustment Service is collecting on an account, it can appear on your credit report as a collection tradeline, separate from the original creditor's listing. Check your credit report directly to confirm, and see the credit report dispute guide if anything about the listing looks wrong.
