TCPA Tools: What They Check, and What They Don't
What is a TCPA tool?
Short answerA TCPA tool is software that reduces the legal risk of an outbound calling or texting campaign under the Telephone Consumer Protection Act. In practice this covers four largely separate jobs: DNC registry scrubbing, litigator scrubbing, phone validation (line type and active status), and consent management. Most vendors specialize in one or two; none of them, alone, makes a campaign compliant -- consent is a record only the caller can hold.

"TCPA tools" gets searched by people trying to figure out what category of software actually solves their problem, and most of what ranks for it is a single vendor describing their own product as though it were the whole category. It isn't. The tooling in this space splits into four jobs that don't overlap much, and knowing which one you're missing matters more than picking a brand.
| Category | What it checks | Typical access model |
|---|---|---|
| DNC / registry scrub | Whether a number is on the National Do Not Call Registry (or a state registry) | Requires your own SAN; a vendor that scrubs for you uses it on your behalf |
| Litigator scrub | Whether a number is tied to a known serial TCPA filer, from court records | No SAN required -- a separate, court-sourced database |
| Phone validation | Line type (mobile, landline, VoIP), active status, carrier | No SAN required -- a carrier data lookup |
| Consent management | Whether, when, and how a specific consumer agreed to be contacted | An internal records system, not a lookup against external data |
Why one tool rarely covers all four
The four checks pull from genuinely different sources: a federal registry maintained by the FTC, a private database built from public court filings, live carrier routing data, and your own records of what a consumer agreed to. A vendor built around one of these -- say, registry access -- has no particular advantage building the others, and the FTC's access rules mean the registry check specifically can't be resold without your credential regardless of who's technically running the query.
In practice this means most tools specialize. DNC-registry vendors sell subscriptions gated on a SAN. Litigator-scrub vendors sell access to their own filer databases, sometimes bundled with validation, sometimes not. Validation-only vendors sell carrier lookups with no TCPA-specific data at all. Consent platforms are a separate software category entirely, closer to a CRM than a scrubbing tool.
What actually determines TCPA exposure
Two of the four answer directly to a legal rule: consent, and -- for telephone solicitations -- the National Do Not Call Registry, which you may not call into without consent or an established business relationship. Litigator screening and phone validation are risk reduction on top of those:
- No consent, clean everything else is still a violation. Scrubbing cannot manufacture consent you never obtained.
- Documented consent, no scrubbing leaves you exposed to the specific population most likely to sue -- serial litigators, who pass every validation check because their numbers are ordinary active mobiles.
- Registry scrub without a litigator scrub filters out people who don't want to be called and leaves in the people who most want to be called, because litigation is the point.
A working process needs consent held internally, a registry scrub run under your own SAN, and a litigator-plus-validation pass on the list before every campaign. No single vendor sells all three pieces as one product, and treating "buy a TCPA tool" as a single purchase decision is usually where teams get the coverage wrong.

Where NumberBroom fits
Carrier-level validation and a court-sourced litigator scrub, bundled in one list upload, at $0.20 per number with a $5 minimum and no subscription. That's two of the four categories above -- the two that don't require a SAN, which is why the whole thing runs self-serve with no account setup. A third is partly covered: sign in and link your own SAN, and a paid scrub adds a federal Do Not Call Registry check, included free on lists of up to 1,000 numbers. Registry access and consent records stay yours to hold, the way the FTC's rules require them to be, and state lists are not covered.

Frequently asked questions
What's the difference between a DNC tool and a litigator scrub tool?
A DNC tool checks the National Do Not Call Registry -- people who formally opted out of telemarketing. A litigator scrub checks a court-sourced database of people who file TCPA lawsuits. The overlap between those two populations is small: serial filers typically stay off the registry, because being called is how they generate claims. A tool that only does one of the two leaves the other risk fully open.
Do I need a separate consent management tool?
If you're relying on written consent forms across multiple channels or sellers, generally yes -- something has to hold the timestamp, IP address, and exact language a consumer saw, and produce it years later if a claim is filed. No scrubbing tool, including NumberBroom, does this. It's a records-management job, not a list-hygiene job, and the two shouldn't be confused.
Is phone validation the same thing as a TCPA tool?
Not by itself. Phone validation tells you whether a number is a live mobile, landline, or VoIP line -- useful for deliverability and cost, and useful for TCPA risk because autodialer rules turn on line type. But validation alone says nothing about DNC status or litigator history. It's one input into a compliant process, not the whole thing.
Can one tool do all four jobs?
Some enterprise platforms bundle DNC scrubbing, litigator scrubbing, and validation under one subscription -- usually priced and sold as a compliance suite rather than a per-check product. Consent management is typically a separate system even at that scale, because it's a records function, not a scrubbing function. For a smaller operation, it's common and often cheaper to combine a self-serve carrier-validation-plus-litigator tool with your own SAN-based registry access, rather than buying a full suite for occasional use.
