About

BulkChecker is a B2B contact verification and data quality platform for teams that need to clean phone number and contact lists before outreach, CRM updates, or messaging workflows. Users can upload CSV or TXT files, run bulk phone validation, carrier lookup, WhatsApp, Telegram, Viber, and other messaging-app checks, then export structured results for cleaner segmentation and operations. The platform supports no-code batch uploads and API-based verification workflows. BulkChecker helps identify invalid, unreachable, duplicate, recycled, or incorrectly formatted numbers, and provides useful signals such as carrier, line type, registration status, and active indicators where available. It is designed for growth, sales, marketing, data operations, and fraud-prevention teams that need faster list cleaning and more reliable contact data at scale.
