Most TCPA lawsuits don’t come from random consumers. A large share come from a small, identifiable group of repeat plaintiffs and the attorneys who file for them. Contact Center Compliance, one of the oldest vendors in this space, says about one-third of TCPA suits come from serial plaintiffs and litigators. Whatever the exact number, the takeaway for anyone running outbound calls or texts is the same: if you can identify those numbers before you dial, you avoid a large part of your exposure.
That is what a TCPA litigator scrub does. Below is a practical look at the companies that offer it, what each one actually provides, and how to choose.
Litigator scrubbing vs. Do Not Call scrubbing
A DNC scrub checks your list against the National Do Not Call Registry, state DNC lists, and your own internal suppression list. That is legally required for telemarketing. A litigator scrub is different. It checks your numbers against a database of people who have filed TCPA lawsuits, sent demand letters, or filed repeated complaints, plus the attorneys behind them. It isn’t required by law. It’s a risk filter that removes the contacts most likely to turn a single call into a federal case.
Most serious outbound programs run both. Several of the vendors below bundle them.
Companies that screen outbound lists against TCPA litigators
1. TCPALitigatorList.com
TCPA Litigator List has been operating since 2017 and focuses on litigator suppression. The company says its database holds over 600,000 names, including individual plaintiffs, professional and multi-case litigators, demand-letter “trolls,” plaintiff attorneys, and frequent DNC complainers, and that its researchers update it every weekday. You can upload a CSV or Excel file with multiple phone columns and download a clean list, or connect through a real-time API that checks each number before the call and blocks it on a match. A Name Recognition Algorithm flags serial litigators by name, which helps catch plaintiffs who switch to new prepaid numbers. The service also scrubs against federal and state DNC lists. Pricing is published: a Basic plan at $199 a month, and API plans starting at $299 a month that scale to enterprise tiers.
2. Contact Center Compliance (DNC.com) – Litigator Scrub
DNC.com has been in call center compliance for more than 20 years. Its Litigator Scrub runs alongside its wireless, VoIP and DNC scrubs, and the company says its litigator data is updated in real time from original court documents. It offers a REST API and lists about 20 integrations, including Five9, Genesys, Salesforce, Convoso, RingCentral, Vicidial and PhoneBurner. Pricing isn’t published; you book a meeting.
3. The Blacklist Alliance – TCPA Litigation Firewall
Blacklist Alliance’s firewall scrubs against its own high-risk data plus your internal DNC list, the National DNC Registry and state registries, for both inbound and outbound campaigns. It’s widely used in lead generation, partly because it is available as a LeadConduit (ActiveProspect) add-on. Subscribers also get access to online TCPA compliance training.
4. PossibleNOW – DNCSolution
PossibleNOW is aimed at enterprises. DNCSolution checks calls in real time against federal, state, internal, wireless, reassigned-number and known-litigator lists. It’s a fit for large financial, insurance and healthcare operations that want litigator suppression as one layer of a wider consent and preference program.
5. Gryphon
Gryphon puts litigator screening inside a broader real-time compliance platform that also enforces DNC rules, consent and calling-hour restrictions at the dialer level. It’s worth a look if you want one control point across many agents and dialers, but you’re buying a platform, not just a list.
6. Trestle – Real Contact
Trestle is mainly a phone validation and data quality API: line type, carrier, whether the number is active. It also includes a litigator-risk flag. It works well as an add-on at the lead-intake stage, though it isn’t a dedicated litigator database.
How to choose
- Coverage beyond plaintiffs. Ask whether the database includes demand-letter senders and plaintiff attorneys, not just people named in filed cases. Many TCPA claims settle before anyone files.
- Update frequency. Serial plaintiffs register new numbers constantly. Daily or weekday updates should be the minimum.
- Name matching. Matching by phone number alone misses a litigator’s new number. Name-based matching closes that gap.
- Real-time vs. batch. Batch scrubs suit campaign lists. Real-time API checks suit inbound leads, dialers and SMS platforms where numbers arrive constantly.
- Integration. Confirm the vendor connects to your dialer, CRM or texting platform before you sign.
- Transparent pricing. Published pricing makes it easy to compare cost per scrub at your volume.
What a scrub won’t do
Removing litigators lowers your exposure. It doesn’t fix a consent problem. You still need documented prior express consent where the law requires it, a working opt-out process, and calling-hour controls. The FCC’s revised opt-out rules take effect November 25, 2026, so this is a good time to check your revocation handling too. Treat litigator scrubbing as one layer of a compliance program, not a replacement for one.
If you’re deciding where to start, run a sample of your current list through TCPALitigatorList.com and count how many known litigators and plaintiff attorneys are already on it. That number usually makes the case on its own.
