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

FairValid is a web-based email verification and contact discovery service for marketing and sales teams, agencies, and developers. Users can check a single email address or upload a CSV list for bulk validation, with results that classify addresses as valid, invalid, catch-all, or unknown while retaining the corresponding source rows. The FairMatch feature lets users search for work contacts by role, company, or location, then uses credits when a verified work email is delivered. Email verification and contact search draw from a shared credit balance, with 300 free credits available each month. Teams can use the results to review and clean campaign lists, qualify work contacts, and prepare outreach data before sending campaigns. The service is accessed through a browser and combines list validation with contact search in one account.
