Our pick

1

1. 1Lookup

Best for scrubbing, validating and tracing numbers in one account

What it checks

The Do Not Call registry and known TCPA litigators, serial complainers and attorneys, with the line type and a next step: approve, review or block

How it bills

10 credits per matched number, about $0.05 on the $99 a month Starter plan; a number that matches nothing is not charged

How a list runs

One US number through the API, or a whole list as a CSV upload in the dashboard

Why it’s on the list: one account scrubs a number against Do Not Call and known litigators, confirms its line type and carrier, and traces numbers for contacts you are missing, from one credit balance.

Also included: phone validation (1 credit) confirms whether a number is active, one number can be checked free with no account on the DNC check, the 7-day free trial needs no payment today, and unused monthly credits roll over for 3 months, and the same account comes with an MCP server for AI agents and Zapier, Make and n8n apps.
