What Should I do if I Haven't Received a Confirmation Email?
If you didn't previously have a geocaching.com account and just signed up, you will get a confirmation email to the email address that you provided. Make sure to check your junk mail and also double check that you entered your email correctly when signing up. Some users incorrectly enter their email which will cause confusion. If you think you entered it incorrectly you can just signup again.
You can also resend the validation email.
