Validate every number before you dial

Leadify validates phone numbers for line type, country, format, and live reachability so cold callers stop wasting hours on dead numbers and SMS campaigns stop blasting landlines.

Phone lists rot fast. Numbers get reassigned, ported, or disconnected, and the cost shows up in your team's dial time. SMS campaigns are worse: blast a landline and you waste credit and risk carrier penalties. Leadify validates every number for format, line type, country, and live reachability, so you only pay your sequencer for numbers worth dialing.

How it works

Send numbers to validate — Upload a CSV, paste a list, or run validation automatically as part of any Leadify discovery or enrichment workflow.
Format and country check — We normalize each number to E.164, confirm a valid country code, and detect the country and region.
Carrier and line type lookup — We identify mobile, landline, VoIP, and toll-free, plus carrier where available.
Classify and return — Each number gets a clear status with line type, country, and any DNC flag, ready for your dialer or SMS platform.

Questions and answers

How accurate is line type detection?

We use carrier and number-portability data, so line types are accurate including ported numbers that originated as landlines but are now mobile.

Do you check do-not-call lists?

Yes. US numbers are checked against the FTC DNC registry. International DNC equivalents are checked where available.

Will this slow down our outreach?

No. Validation runs in seconds in bulk and can be inlined into any Leadify workflow before export, so the data lands clean in your dialer.

Is this GDPR and TCPA aware?

Yes. Validation respects data-handling rules and includes flags relevant to TCPA compliance for US SMS campaigns.
