A skip trace answers one question: whose name and number is on file for a property. It's genuinely useful — most of an outbound list starts as an address, and a trace is what turns that into a person you can call. What it doesn't do is confirm that the number it hands back is still connected, still a mobile line, or safe to dial.
The gap between "matched" and "dialable"
A records match and a live phone check are different operations pulling from different data. Skip-tracing sources — credit headers, public records, property databases — are updated on their own schedule, sometimes infrequently. The number attached to a record can be accurate the day the record was compiled and wrong by the time you dial it, because the underlying phone line changed hands or was disconnected in between.
This shows up as a real, specific pattern practitioners run into: a cheap or bulk skip trace returns a higher share of old landlines and recycled cell numbers than a fresher, more expensive one. The trace isn't wrong, exactly — it's reporting what its source records show. It just isn't reporting what's true on the line right now.
A skip trace can't tell you these three things
Is the line still connected? A disconnected number looks identical to a live one in a records match.
What type of line is it? A number that was a landline when the record was created may be a mobile now, or the reverse — number portability breaks any assumption based on the original record.
Is the owner a known TCPA litigator? Nothing in a skip trace's public-records sources flags serial filers. That's a court-record-sourced check, not a property-ownership one.
Why this matters more for a skip-traced list specifically
Skip-traced leads tend to be older and more indirect than opt-in leads — you're often calling someone who has never interacted with your business and doesn't know you have their number. That combination raises the stakes on both halves of the problem: a wasted dial to a dead number costs you time you can't get back on an already-cold lead, and a dial to a serial litigator on a list you can't show was screened is a materially worse position to defend than the same mistake on a list where you documented a check.
The two-step handoff
- Skip trace to get a name and number attached to a property or lead. This step is outside what NumberBroom does — plenty of dedicated tools handle it well.
- Validate and screen before you dial. Carrier-level validation confirms the number is live and reports its actual line type; a litigator scrub checks it against a court-sourced database of serial TCPA filers. Both run in one CSV upload, in parallel, at $0.20 per number with a $5 minimum.
Treating these as one combined step is where lists get burned. A skip trace that returns 1,000 numbers isn't 1,000 dialable leads — it's 1,000 candidates, some real percentage of which are disconnected, wrong line type, or carrying legal risk the trace itself has no way to see.

Frequently asked questions
Does NumberBroom do skip tracing?
No. Skip tracing finds a name, address, or phone number for a property owner from public records, credit headers, and similar data sources — it's a records-matching problem. NumberBroom starts one step later: once you have a phone number from a skip trace (or any other source), it validates that number at the carrier level and checks it against a TCPA litigator database. Two different jobs, and most skip-tracing tools don't do the second one at all.
Why does a skip-traced number sometimes not work?
Skip-tracing data is a records match, not a live check. It can return a number that was correct when the underlying record was last updated and is wrong now — disconnected, reassigned to someone else, or ported to a different carrier. Cheaper skip-tracing sources in particular tend to surface older, recycled records, which is why a low-cost trace often returns a higher share of dead landlines and reassigned cells than a name-matched, freshly-verified one.
If I skip traced the number myself, do I still need to check it against TCPA litigators?
Yes — the two are unrelated. A skip trace tells you whose name is associated with a number in public records. It says nothing about whether that person has filed TCPA lawsuits before. Serial litigators are ordinary people with ordinary phone numbers; nothing about how the number was sourced changes that risk.
Does scrubbing a skip-traced list check the Do Not Call Registry?
Not as part of NumberBroom's carrier-validation-plus-litigator-scrub — registry access runs through your own SAN and stays your obligation as the caller. See what a SAN actually gates. What NumberBroom does check is whether the number is even a working, callable mobile line, and whether it belongs to a known litigator — two separate risks a DNC scrub alone won't catch.
