About

1Lookup is an enterprise-grade data verification and intelligence platform that gives businesses real-time, high-accuracy validation for phone numbers, email addresses, and IP addresses through a unified API, helping ensure data quality, reduce fraud, and protect user experiences. It aggregates data from authoritative sources, including carrier networks, FCC databases, and global threat feeds, with daily updates to deliver sub-second verification results that detect invalid, risky, or fraudulent identities, improve deliverability, and flag disposable or suspicious contact data. The core services include phone validation with HLR and carrier lookup, phone spam and risk detection, email address validation with SMTP checks and disposable domain screening, and IP intelligence for precise geolocation, proxy/VPN detection, and risk scoring, all accessible via modern REST API calls that scale to millions of daily lookups without rate limits.

About

We are the experts for phone number lookups to determine phone line type. Do you need to know if phone numbers are mobile, landline, toll-free, VOIP, or fake/invalid? We cover all line types and all U.S phone companies. Run a phone number search above to see our uncanny accuracy. You can automate phone validator lookups with the phone validator API. Join the many app developers and marketing agencies who already use the API to keep their project phone numbers validated in real time. Our batch processing makes updating your phone lists easy. To run a phone number batch, just upload your CSV file and we'll do the work and email your file back.
