Based on: Get a verification code and sign in with two-factor authentication - Apple Support

A code is sent first to your trusted devices (some other Apple computer or Apple mobile device signed in with your account) automatically. If you have a trusted device running iOS 9 and later, OS X El Capitan and later, iPadOS 13 and later, or watchOS 6 and later, the verification code is displayed automatically on your trusted devices.

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

1. Select “Didn’t Get a Code?” or “Can’t get to your devices?” on the verification code 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.

It is a good idea to have more than one trusted number.

Contact Apple. Refer to this page for Apple Support for different countries ➔

Choose your country or region - Official Apple Support

Select your country (if you do not see your country, also look for "other" in regions; e.g., "Other Africa"), then "Choose a product". Click the "show" item under each category for more selections. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

If after all that you still can’t receive verification codes, you can request account recovery to regain access to your account [ How to use account recovery when you can’t reset your Apple Account password - Apple Support ]. Account recovery might take a few days or longer, depending on the specific account information you can provide to verify your identity.

Apple does not allow account verification by email. It either has to be a verification code from a trusted number, a trusted device, or a recovery contact. If you do not have any of those then you will have to request account recovery.

If you were using two factor authentication it should be essentially impossible for somebody to "hack" your account unless they have one of the above trusted methods. If you were not using two factor authentication then this is the reason why Apple repeatedly reminds a user not using it and has been doing so for several years now..
