NumberLookup tells you which numbers on a phone list can be reached, and how, before you pay to text or call them.
Upload a CSV of up to 500,000 rows, call the REST API, or check one number on the homepage without an account. Every US and Canadian number comes back with a verdict: Textable (a mobile line), Callable (a landline or other voice line), Invalid (not a working number) or Unknown. You also get the line type, carrier, region and whether the number was ported. Download the cleaned list as one file, or split by verdict, so texts go to mobiles and callers skip dead numbers.
It's built for teams who text and dial lists: real estate investors and wholesalers working skip-traced lists, SMS marketers, call centres and lead generation agencies.
Pricing is simple:
One credit per check.
Unknown results, duplicate rows, bad input and errors are free.
Credits never expire.
Buy a pack from $20, or take a monthly plan if you check numbers every day.
New accounts get 1,000 free credits, no card needed.
Cancel a plan from your dashboard.
NumberLookup also checks IP addresses: country, network, Tor exit and hosting-range flags, and a risk level.
What it doesn't do: owner names, skip tracing, or Do Not Call and consent checks. Verdicts tell you whether a number can be reached, not whether you may contact it.
