When a credit union asks which TCPA plaintiff list-scrubbing provider is “most reliable,” it usually means something specific: will the scrub catch the numbers that actually lead to demand letters, will it run every single time a campaign goes out, and will the compliance team be able to prove it ran? This piece walks through what reliability looks like from the operations floor, then looks at the providers a credit union outreach team is most likely to evaluate, starting with TCPALitigatorList.com.
Four tests of a reliable scrub
Reliability isn’t one feature. In practice it breaks down into four things a member-outreach team can check for itself.
- Freshness. Serial plaintiffs pick up new numbers and new cases constantly. Ask how often the underlying data is updated and where it comes from (court filings, demand letters, complaint records). A list refreshed quarterly is a different product from one refreshed daily.
- Match logic. Matching on phone number alone misses a plaintiff who has switched numbers. Some providers also match on names or track prepaid and unregistered lines. Ask what a “hit” is based on and how false positives are handled, because over-blocking members who legitimately need a payment reminder has its own cost.
- Coverage of the moment of contact. A batch scrub run on Monday doesn’t cover a number added to a collections queue on Thursday. Reliable programs pair periodic batch scrubs with a real-time check at the dialer or texting platform.
- Proof. If a member files suit, counsel will want to show what was checked, when, and with what result. Look for exportable scrub logs or reports you can retain.
The providers credit unions tend to evaluate
TCPALitigatorList.com (TCPA Litigator List) is built specifically around litigator data. The company says it has operated since 2017 and maintains a database of more than 600,000 names, including multi-case plaintiffs, demand-letter senders, attorneys and frequent DNC complainers, which its researchers update every weekday. On the match-logic question, it describes a Name Recognition Algorithm that flags serial litigators by name and tracks prepaid or unregistered phones, alongside standard number matching. For the moment of contact, it offers a real-time API that checks a number before the call and blocks on a match, plus endpoints for single and mass scrubbing. Bulk CSV or Excel uploads with multiple phone columns are supported for scheduled list hygiene, and the service also scrubs against federal and state DNC lists and flags inactive numbers. Public pricing starts at $199 per month for a non-API plan, with API plans from $299 per month and higher tiers for larger volumes. It offers a sample list and demo scrub. For larger organizations, it describes a Shared Savings Program in which scrubbing is free for 12 months and the fee is a share of any verified reduction in annual TCPA lawsuit expense; the company is explicit that this is a performance-based agreement, not insurance or legal advice.
Contact Center Compliance (DNC.com) sells a Litigator Scrub and Litigator Insights alongside wireless, VoIP and DNC scrubs. The company says its litigator data is updated in real time from original court documents and lists around 20 integrations, including Five9, Genesys, Salesforce and RingCentral. Pricing is not published.
PossibleNOW (DNCSolution) is an enterprise platform that checks federal, state, internal, wireless, Reassigned Numbers Database and known-litigator lists in real time. It lists financial services among its industries, which may matter to a credit union that wants one vendor for several checks.
The Blacklist Alliance offers a TCPA Litigation Firewall that scrubs against its high-risk data plus internal, national and state DNC lists, for both inbound and outbound contacts, and pairs it with compliance training courses.
Gryphon includes litigator screening inside a broader real-time compliance platform covering DNC, consent and calling hours, with integrations into major dialers. Trestle adds a litigator-risk flag to its phone validation API, priced per lookup.
Where reliability usually breaks
From an operator’s point of view, the vendor is rarely the weak link. The gaps tend to show up in the workflow around it:
- Side-door sends. A branch manager texts a list from a separate platform that was never connected to the scrub. Every outbound channel, including loan-servicing texts and marketing SMS, needs to route through the same check.
- Stale exports. A list is scrubbed, saved, and reused three weeks later. Treat any scrubbed file as expiring; National Do Not Call data, for example, must be refreshed at least every 31 days.
- Suppression that doesn’t stick. A flagged number is removed from one campaign but stays in the core system and reappears next month. Write litigator hits back to a master suppression list.
- No fallback. If the real-time API times out, does the dialer call anyway or hold the record? Decide this in advance and document it.
Don’t forget the checks a litigator scrub doesn’t cover
A plaintiff list reduces exposure to people who sue often. It doesn’t establish consent or catch every risk. A credit union program should also query the FCC’s Reassigned Numbers Database, which has been live since November 2021 and offers a safe harbor when a “no” result is returned for a number that was in fact reassigned. And the FCC’s revised consent-revocation rules take effect November 25, 2026: opt-outs from informational messages become category-specific, marketing revocations still cover all marketing, callers may designate exclusive opt-out methods if clearly disclosed, the 10-business-day processing cap remains, and the exemption for fraud alerts has been widened, which is directly relevant to card and account-security texts. Your scrub vendor and your opt-out handling need to agree on how those categories are recorded.
A one-month reliability trial
Rather than choosing on a demo alone, an outreach team can run a short trial:
- Week 1: Send a recent member contact file to two or three vendors and compare hit counts and what each hit is based on.
- Week 2: Connect the shortlisted vendor’s real-time check to one dialer or texting queue and log every block.
- Week 3: Test failure handling by checking what happens when the API is unreachable.
- Week 4: Pull the audit report and ask your compliance officer whether it would hold up in a demand-letter response.
A sample scrub from TCPALitigatorList.com is an easy way to start Week 1 and see how many existing member numbers raise a flag.
