Wrong-person numbers come from a match made on an identifier that more than one person shares [6]. The usual suspects are a common name and a mailing address that was never a residence. SmartSkip puts the distance between finding data and finding correct data in one line, noting that a service can run a 95% hit rate on 50% accuracy [6]. Hit rate counts records where the service found at least one piece of contact information, while accuracy counts how much of what came back is correct [6].
A mailing address on the tax roll says nothing about who sleeps at the parcel, and it often belongs to a property manager. Sometimes it is an address the owner left behind years ago. Anchoring a trace on that address hands the matcher a person who does live there and has no connection to the property, so the trace registers as a clean success in every metric the vendor reports back.
PropertyRadar's owner profile carries a status icon on every phone number [11]. A green checkmark marks a number that is active and safe to call, and a yellow triangle covers statuses including Opted Out, Wrong Person, Disconnected, Do Not Call, and Blacklisted [11]. The Wrong Person label exists because the outcome shows up often enough to need a place on the record, and the same page reminds users that phone numbers may be subject to state and federal do-not-call regulations and that compliance sits with the user [11].
PropertyRadar publishes one accuracy number and labels where it came from [10]. Its guide reports that customers have described an accuracy rate of 80% or better, while adding that no skip-tracing service reaches a 100% accurate match rate [10]. A customer-reported figure has no stated sample and no definition of what counted as accurate, which is a long way from a measurement you could reproduce on absentee owners in one county.
