How we handle consent and opt-outs
LeadNumbers supplies business contact data for legitimate business-to-business outreach. Records are sourced from licensed providers and public professional sources, and are intended for calling the person in their professional capacity.
You remain the caller, so local calling rules, registration and consent requirements are yours to follow. We help by supporting suppression lists, honoring opt-outs platform-wide within one business day, and keeping provenance on every record so you can answer a question about where a number came from.
FAQ
Quality questions
Where do the mobile numbers come from?
Numbers are enriched through licensed contact data providers and verified before delivery. Every lead carries provenance showing the source and the date it was retrieved.
What accuracy should I expect?
Contact data decays constantly, so no provider is perfect. LeadNumbers publishes the flag rate on your dashboard and replaces anything wrong free rather than arguing about a percentage.
Do you honor do-not-call and opt-out requests?
Yes. Opt-outs are suppressed across the whole platform within one business day and never resupplied to any account.
