iCloud is not sending verification code to trusted line on OS X Yosemite

Greetings jimi213,

It sounds like two-factor authentication was enabled for your Apple ID. Due to this, a verification code is required anytime you're required to sign in with your Apple ID credentials.

Check out this link to learn more about receiving verification codes: Get a verification code and sign in with two-factor authentication - Apple Support. Since you do not have access to a trusted device, you may want to follow these steps:

Get a text or phone call

If you don’t have a trusted device handy, you can have a verification code sent to your trusted phone number as a text message or phone call.

1. Click Didn't get a verification code on the sign in screen.

2. Choose to have the code sent to your trusted phone number.

3. You'll get a text message or phone call from Apple with your verification code. This text message might include an additional domain validation line. This line includes the @ symbol, the website name, and your code (for example: @icloud.com #123456 %apple.com).

4. Enter the code on your other device to complete sign in.

If it does not work, as it shows there, you'll need to start the account recovery process.

If you still can't sign in

If you can’t sign in, reset your password, or receive verification codes, you can request account recovery to regain access to your account. Account recovery might take a few days or longer, depending on the specific account information you can provide to verify your identity.

Kind regards!
