How can I access my Apple ID without a verification code?

Huhu,

I would like to log in with my Apple ID with another cell phone number or with a laptop. For this, however, it needs the authentication code from my telephone number, to which I no longer have access.

how can I register at all to verify a new number?

If you still have a mobile phone or Mac on which the Apple ID is activated, the code will be sent there.

Otherwise you can press "did not receive code" or something like that when logging in and it will then suggest other ways. Or Apple Support always helps.

Hmm then I'll try to reach the support somehow. The other ways lead nowhere
