I did not receive a verification code or email
You asked for a verification code or an email from CoinUnited.io, but nothing arrived.
Check why the code or email is missing
- Check the address or number
For an email code, check that you typed the email address correctly and that you are looking at the email account registered with CoinUnited.io. For an SMS code, check that the phone number bound to your account is correct.
- Check your junk folders
Look in your junk or spam folder for email. Look in your SMS bin for text messages.
- Check your inbox and your phone bill
Make sure your email inbox is not full. A full inbox cannot receive new emails. For SMS, check whether your phone bill is overdue.
- Check your security software and your email provider
Make sure your firewall or antivirus software does not block mail from your email server. Use a common email provider, such as Gmail or Outlook.
- Wait, then try again
A code can arrive a few minutes late. Try again after 10 minutes.
If you find CoinUnited.io emails in your spam folder
Add CoinUnited.io’s email addresses to your safe senders (whitelist) so later emails reach your inbox. See How to Whitelist CoinUnited.io Emails?
If you are registering and no code arrives
One email address and one phone number can link to only one account. If you do not receive the verification code, your email address or phone number may already be registered. Try logging in, or reset your password.
If you can no longer receive codes on your email or phone at all
Click “Didn’t receive the code?” on the verification screen. Under “Reset Security Settings”, select the options that are not working and follow the steps. You cannot withdraw for 24 hours after you change these settings.
If the code arrives but your Google Authenticator code is rejected
Set your phone to update its time automatically. See How to Fix Google Authentication (2FA) Code Error?
