Hello SRanford,
Welcome to Apple Support Communities. It sounds like you may be looking for your verification email. If you don't have access to that email address, it may also be sent to a rescue email as mentioned in the following sections of If you didn't receive your verification or reset email - Apple Support.
"2 Make sure you're checking the correct email account
If you're looking for a password reset email, make sure you're checking the correct email inbox. It will either be your primary Apple ID email address or a separate rescue or notification email address that you added to your account.
If you're looking for a verification email, you can sign in to your Apple ID account page and review all the email addresses you have on file, including the one that you're trying to verify. If the email address is incorrect, you can update it and send another verification email.
3 Resend the email
To resend a reset email, repeat the steps to reset your password or security questions, and we'll send an email to your rescue or primary Apple ID email address.
To resend the verification email, sign in to your Apple ID account page. Click Resend next to the email address that you want to verify, and we'll send an email to that address."
Or are you being asked for a verification code from your email? If so, do you have any devices that are signed in with your Apple ID? You may be able to get a verification code using an alternate method shown in Get a verification code and sign in with two-factor authentication - Apple Support.
Take care.
