Walmart Voiceprint Lawsuit, Was Your Call Recorded? — Krupke v. Walmart Inc., No. 1:26-cv-09305

Quick answer: if you’ve called a Walmart customer service line while living in Illinois, there’s a good chance your voice became a database entry. A new class action says Walmart’s AI system builds a “voiceprint” from every call — and never asked permission the way Illinois law requires.

Who Is Walmart and Why Is Its Call System Being Sued?

Walmart runs customer service lines for its stores, supercenters, and Sam’s Club locations, letting shoppers check on prescriptions, service appointments, and orders by phone. The lawsuit says that convenience comes with a catch: every call routes through an AI system that isolates the caller’s pitch, cadence, and tone to build a unique voice template, which Walmart then keeps on file to match future calls. That template is the “voiceprint” at the center of this case.

What Did Walmart Do With Callers’ Voices?

Plaintiffs Carol Krupke, a Freeport, Illinois customer, and Jeanne Thomas, who calls Walmart stores in Vandalia and Effingham, say they were told only one thing before their calls were processed: “This call and your voice may be recorded for business purposes.” Nothing in that message explained how long Walmart would keep the recording, who else might see it, or how to opt out. Krupke called Walmart three separate times — February 18, 2025, July 2, 2025, and May 1, 2026 — and says her voice was converted into a template each time.

That gap is what Illinois’ Biometric Information Privacy Act exists to close. BIPA requires a company to tell you in writing, before it happens, that your biometric data is being collected, why, and for how long — then get your signed release. A voiceprint counts as a biometric identifier under the law, the same as a fingerprint or a face scan. Walmart’s privacy policy, last updated June 18, 2026, does disclose that it collects voiceprints — but the lawsuit argues a general policy buried in fine print isn’t the specific, advance written notice BIPA demands. Walmart isn’t the first big retailer to face this exact argument: Home Depot fought a nearly identical claim over its in-store facial recognition, and the theory has also reached AI meeting tools — Fireflies.AI is defending a similar voiceprint case over its notetaking bot.

If a company’s privacy policy mentions biometric data somewhere on page six, that isn’t the same as asking you first — and BIPA treats the difference as the whole point.

Are You Part of the Walmart Voiceprint Lawsuit?

Here’s exactly how to know if this case includes you.

• Illinois residents who called any Walmart customer service line, including store, pharmacy, or auto center lines
• Sam’s Club members in Illinois whose calls went through the same automated voice system
• Anyone who spoke with the system rather than only pressing phone-menu buttons, since that’s when a voiceprint is built
• Callers going back several years, since BIPA claims can reach further back than many people assume

This case is limited to people who were Illinois residents at the time they called. Customers who called from other states, or who only ever pressed keypad options without speaking, fall outside what the complaint describes.

Walmart Customers Outside Illinois — Are You Still Covered?

No. BIPA is an Illinois-only statute, and this class is defined as Illinois citizens. If you live in another state, this particular lawsuit doesn’t apply to you — though a handful of other states have passed narrower biometric privacy laws of their own, so it’s worth checking your state’s rules separately.

Not sure if your calls to Walmart put you in this class? A free consultation with a data privacy attorney can help you sort that out.

What Are Walmart Customers Asking the Court to Award?

No settlement and no claim form yet. The complaint asks the court to declare Walmart’s practices unlawful, order it to start complying with BIPA, and award statutory damages of $1,000 to $5,000 for each violation, plus attorneys’ fees.

What Could Class Members Receive If This Case Resolves?

Too early to say. BIPA cases against large companies have produced very different outcomes — some settle for hundreds of millions, others get dismissed or narrowed on technical grounds before trial. With potentially hundreds of thousands of Illinois calls at issue, the numbers here could move in either direction.

What Should Affected Walmart Customers Do Right Now?

1. Nothing is required yet — there’s no settlement or claim form, so there’s nothing to file.
2. Think back on whether you called a Walmart customer service line while living in Illinois, and roughly when.
3. Save any phone records or account history that show those calls, in case you need them later.
4. Watch the Northern District of Illinois docket, case No. 1:26-cv-09305, for a motion to dismiss or a class certification ruling.
5. If you’d rather have your situation reviewed individually instead of waiting on the class, talk to a data privacy attorney now.
6. Read anything Walmart sends you about account terms or arbitration carefully before agreeing to it — arbitration clauses are often contested early in BIPA cases.

Walmart Voiceprint Lawsuit — Frequently Asked Questions, No. 1:26-cv-09305

Is there a lawsuit against Walmart for collecting customer voiceprints right now?

 Yes. Carol Krupke and Jeanne Thomas filed a proposed class action against Walmart Inc. on August 4, 2026, in the U.S. District Court for the Northern District of Illinois, No. 1:26-cv-09305.

Do I need to do anything right now to be part of the Walmart voiceprint lawsuit?

 No. There’s no claim form yet. If you’re an Illinois resident who called Walmart’s customer service line, save what records you have and wait for developments.

When will the Walmart voiceprint case settle?

 There’s no timeline yet. The complaint was filed August 4, 2026, and Walmart had not filed a response as of August 6, 2026.

Can I file my own lawsuit against Walmart instead of joining the class?

 Yes, and other Illinois consumers already have — separate BIPA suits over Walmart’s voice system have been filed in both Illinois state and federal court. Talk to an attorney about which path fits your situation.

How will I find out if the Walmart voiceprint lawsuit settles?

 Watch the Northern District of Illinois docket for case No. 1:26-cv-09305, or check back here for updates as the case develops.

What does “lead plaintiff” mean for the Walmart case, and why does the deadline matter?

 It doesn’t apply here. Lead plaintiff deadlines come from securities class actions; this is a BIPA privacy case brought by two named class representatives, Krupke and Thomas.

What specific laws does Walmart allegedly violate?

 The complaint cites the Illinois Biometric Information Privacy Act, 740 ILCS 14/15(b), for collecting voiceprints without written notice and consent, and 740 ILCS 14/15(c) and (d)(1), for allegedly sharing that data without permission.

How much could affected customers get if this case resolves?

 The complaint asks for $1,000 to $5,000 per violation under BIPA, but no amount has been awarded or agreed to. Any eventual recovery would depend on how the case proceeds.
