[email protected], [email protected], [email protected] and [email protected]. Whitelist them, wait 10 minutes, then request the code again.
Which email should I sign up with?
Binance recommends a common email domain such as Gmail or Outlook. For OKX, follow its help center page.
Still nothing. What should I give support?
OKX asks for your app version, a screenshot of the code countdown, the email address that isn't getting the code and the time you requested it. For Binance, follow its help center page.
If I reopen the sign-up page, is the referral code still there?
Reopen it from a sign-up button below and the code is filled in again; check the code box before you submit: Binance FAIRR, OKX FAIRR.
Someone offers to receive the code for you. Is that real?
No. Codes only go into the official website or app; anyone asking you for a code is a warning sign.
