Confirm CoinW exchange account presence using either a phone number or an email address.
CoinW is a crypto exchange popular in Asia among retail and derivatives traders, known for copy-trading features alongside spot markets. CheckNumber's CoinW checker confirms whether a phone number or email belongs to a registered CoinW account, useful for screening reward lists for Sybil activity or qualifying exchange-focused leads in that region, without ever logging in, messaging, or contacting the user.

Core CoinW data
What each CoinW task returns
The result file maps one row to each submitted record with the fields below.
Registration by phone
coinW - Number

- coinw
- Whether the number has an active CoinW account (yes or no).
Registration by email

CoinW FAQ
Can I check whether numbers or emails are on CoinW in bulk?
Yes. Upload a CSV of phone numbers or email addresses, or call the REST API, choose the matching task type, then download a result file with a registered or not-registered verdict for each record. You are billed only for successful checks.
Why check CoinW rather than a Western-focused exchange?
CoinW's user base is concentrated among Asian retail and derivatives traders, so a CoinW-registered signal can surface an audience segment that a Binance- or Coinbase-only check would miss.
Do you check by phone number, email, or both?
Both. The coinW task type checks phone numbers and the coinw_email task type checks email addresses against CoinW registration, so you can use whichever identifier your list contains.
Does the check contact or notify the CoinW user?
No. The check is passive and reads registration signals only. Nothing is sent to the number or email, and the account holder is never contacted, logged in to, or notified.
