An empty contact panel means the aggregated consumer files hold nothing for that contact. PropertyRadar's documentation states that when phone numbers or email addresses are not available for a contact, no purchase links or icons appear [1]. Nothing was charged and nothing broke, so the row needs a channel that works without a number.
A number that came back carrying a status flag describes a different failure. The owner profile marks an active number with a green checkmark and flags a yellow triangle for statuses including opted out, wrong person, disconnected, do not call and blacklisted [2]. Email addresses carry their own set covering opted out, wrong person, reported, blocked, bounced or undeliverable [2]. Two of those labels, wrong person and bounced, point at an identity problem, because a person was matched and the wrong one came back.
Re-running the same row against the same database returns the same result at full price, since a purchased contact already includes every available number and address [1]. Retail skip tracing runs 10 cents to 50 cents per record by PropertyRadar's own estimate, so a second pass over a 2,000-row file costs $200 to $1,000 and buys back rows that already failed [3].
Roughly 35 million U.S. numbers are disconnected and released for reassignment each year, the volume that led the FCC to order the Reassigned Numbers Database into existence [4]. A dead number therefore describes the phone system more than the vendor that sold it. Which of the two failures you are looking at decides the next move, since only one is repaired by another purchase.
The sequence below runs cheapest first and stops at whichever step produces a route to the owner. Free county lookups come before paid searches, and relatives come last because a court filing has to put them in the file [15].
