I don't have 6 code digit

Hi takudzwa224,

Thanks for posting in Apple Support Communities. We may need more information about what is happening and what you'd like to do. However, it sounds like you may be trying to sign in and aren't getting a verification code. Right?

You can get or generate a verification code using a trusted device or phone number. Check out Get a verification code and sign in with two-factor authentication. Since it looks like you might be moving from Android perhaps the phone call or text method would work best. Guidance is below.

"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."

All the best.
