What the 1 public FCC complaint naming this number show about when the calls happened, where they landed and how they were placed. Derived from the FCC Consumer Complaint Data Center, a public record.
This number's complaint record is historic. Nothing has been filed against it since 2021-03-10, so if it called you today the complaints below describe a campaign that ended years ago — or the number has since been reassigned to a different subscriber. Numbers are routinely returned to the carrier and reissued. Treat this page as an archive record rather than a current warning.
All 1 complaints were filed on the same day (2021-03-10) — a single burst rather than sustained calling.
Where the complaints came from
- OH1
Every complaint came from a single state (OH), which is more consistent with a local or regional caller than a national campaign.
How the calls were placed
- Abandoned Calls
- 1
- Internet (VOIP)
- 1
Abandoned Calls: The line was dialled and dropped before anyone spoke — the signature of a predictive dialler placing more calls than it has agents to answer. The FCC's telemarketing rules cap abandoned calls at 3% of answered calls.
Internet (VOIP): Reported as arriving over a VoIP service. VoIP origination is cheap to obtain and quick to abandon, which is why high-volume campaigns favour it.
