Reduce support overhead

Reduce refund requests caused by dead leads. Delivering clean, verified files lowers your support workload and improves client retention.

Justify higher margins

Raw leads are a commodity. Verified, carrier-checked data is a premium asset that justifies a higher price point per record.

Build brand equity

Position your data as 'verified' rather than 'scraped'. Reliability is the only way to build a sustainable, long-term brokerage business.

The workflow

Aggregate your data

Compile your leads from scrapers, opt-in forms, or third-party databases into a single raw CSV file.

Run the validation batch

Upload the file to Numtrue. We query the global telecom networks to identify line types and verify active connections.

Deliver and profit

Export the clean list. Deliver a flawless file to your client, eliminate support tickets, and get repeat business. You can even share results publicly by a share link, to prove your data quality.

Raw data is a commodity. Verified data is a premium asset.

Buyers are tired of paying for dead numbers and disconnected lines. When you run your batches through Numtrue before delivery, you eliminate customer complaints, stop chargebacks, and justify charging higher margins.
