The Lead Quality Problem

Up to 30% of phone numbers in a typical marketing database are invalid, disconnected, or the wrong line type for your channel. Every bad number wastes agent time, burns campaign spend, and risks compliance penalties.

Phone validation removes bad data before it reaches your team — so every dial, text, and outreach dollar counts.

Invalid / disconnected numbers ~18%
Wrong line type (e.g. landline in SMS campaign) ~12%
DNC-registered numbers ~7%

Frequently Asked Questions

How is this different from a reverse phone lookup?

We validate the number’s status and line type — we do not return owner names, addresses, or personal data. We are not an FCRA-regulated consumer reporting agency.

Can I bulk-validate my entire contact list?

Yes — upload CSV files with up to 50,000 phone numbers at once. You can also use the REST API for up to 1,000 lookups per request in real time.

Do credits expire?

Never. Credits stay in your account indefinitely until used. No subscriptions, no monthly minimums — pure pay-as-you-go pricing.

Do you support numbers outside the US and Canada?

Currently we validate US and Canada (NANP, country code +1) phone numbers. International numbers outside the North American Numbering Plan are not supported.
