not sending verification code

I had an old account I used only occasionally for iTunes. Got a used iPhone a couple of months ago, and I want to use my account now to keep track of my contacts etc. I logged in to iCloud.com, and got this message:

You must update your Apple ID to use iCloud.

Take a moment to review and update your account information.

Cancel | Continue

So I clicked Continue, and then got this:

Verify Email Address

Your Apple ID email address must be verified before you can

sign in. Verify the address below or choose a different address.

[box for email address]

Cancel | Continue

The box had my proper email address, so I clicked Continue, and then I got this:

An email with a verification code has been sent to

(my email address). Enter the code here:

[ ] [ ] [ ] [ ] [ ] [ ]

Didn't get an email?

Send a new code

Go Back | Verify

And I have not received a code. When I mouse over "Didn't get an email", it says:

Check your Junk mail folder or wait a

few minutes. If you're still having

trouble, you can request a new code.

I've tried clicking "Send a new code", I've checked my spam folder repeatedly, I've signed out and signed back in, I've waited a few HOURS, and nothing. My husband sent a message to my gmail account and it got through fine. What do I do?
