NumDetect is a bulk phone-number checking platform for business contact-data workflows. Users select a checking product and country, upload a TXT or CSV file, track the asynchronous task and download a product-specific CSV result. Separate products provide phone-number validation, number-activity signals, available e-commerce activity signals, potential high-value signals and carrier context. Each product uses its own task and billing. Results support list review, segmentation and contact-data preparation; inferred signals are not proof of identity, spending power, consent or future customer behavior.
