Three steps. Zero technical setup required.

Export your clean list, push data to your CRM, or integrate results directly via API.
TCPA violations can cost $500–$1,500 per call or text. Our DNC Lookup screens US numbers against the Federal (National) DNC list, 6 state DNC lists and the TCPA Litigator list — so you can see the risk before you make contact. It is a compliance-assistance tool, not legal advice or a guarantee of compliance.
Start Your Free DNC Check (100 credits) →Phone Lookup and DNC Lookup are separate services — or run both in one step with Phone + DNC Lookup (one credit of each per number).
DNC Lookup checks US numbers against the Federal (National) DNC list, the TCPA Litigator list and the state DNC lists of Texas, Florida, Pennsylvania, Indiana, Colorado and Wyoming — all in one lookup. Other states’ own lists are not included.
Uploaded files and results are kept for 10 days, then deleted automatically (you can delete them sooner). Lookup logs are kept for 5 days. We do not sell or share the numbers you check.
In the web app and CSV files, any format: (555) 123-4567, +1-555-123-4567, 5551234567, 555.123.4567 — formatting and a leading 1 are removed automatically. The API takes 10-digit numbers. US and Canada (+1) numbers are supported; DNC Lookup is US only.
The Telephone Consumer Protection Act restricts telemarketing calls and texts, including calls to numbers on the National DNC Registry and autodialed calls or texts to mobile numbers without consent. Statutory damages are $500 per violation, up to $1,500 if willful. Validating numbers and scrubbing DNC lists before dialing is an important first step — for your specific obligations, consult a qualified TCPA attorney.
