Are you required to verify your identity (KYC) before using a Bitcoin ATM? If not, how do they avoid transactions being used for tax evasion or other purposes ?
As mentioned above, if you have multiple questions about ATMs, better make them in one post.
But to answer your question, different countries --> different laws and regulations. Some of them would allow you to buy or sell using your phone number only. You could find that data by going to CoinATMRadar:
