Verify KuCoin Registration by Phone or Email
Confirm KuCoin account presence using either a phone number or an email address.
KuCoin is known as a go-to exchange for altcoin traders, listing a far wider range of tokens than most mainstream platforms. CheckNumber's KuCoin checker confirms whether a phone number or email belongs to a registered KuCoin account, so teams working with altcoin-heavy communities can screen reward lists for Sybil activity or qualify exchange-focused leads, without ever logging in, messaging, or contacting the user.

The result file maps one row to each submitted record with the fields below.

KuCoin FAQ
Can I check whether numbers or emails are on KuCoin 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 KuCoin specifically for an altcoin-focused campaign?
KuCoin lists a broader range of altcoins than most major exchanges, so a KuCoin-registered signal can be a stronger indicator than a Binance-only check when the target audience is drawn from altcoin trading communities.
Do you check by phone number, email, or both?
Both. The Kucoin task type checks phone numbers and the kucoin_email task type checks email addresses against KuCoin registration, so you can use whichever identifier your list contains.
Does the check contact or notify the KuCoin 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.
