CheckCrypto exchanges are high-risk verticals for compliance. A CoinW check helps you understand whether a phone or email already has an exchange footprint before onboarding or retargeting.
CheckNumbers mirrors the product grid you may see on marketplace UIs, but routes orders to @checkerNUM_bot — no API keys required for standard batches.
Pair CoinW verification with messenger checks to prioritize users active on Telegram or WhatsApp.
Check types available
- Registration check
Who uses CoinW checks

Compliance note
