Should phone numbers be hashed?

Should phone numbers be hashed in order to protect user privacy and security? On one hand, hashing phone numbers can help prevent unauthorized access and misuse of personal information. It can also ensure that sensitive data is not stored in plain text, making it more difficult for hackers to steal or exploit. However, on the other hand, hashing phone numbers may also create challenges for legitimate users who need to access their accounts or verify their identities. Additionally, there are concerns about the potential for collisions and the difficulty of reversing the hashing process if needed. So, what is the best approach to balancing security and usability when it comes to hashing phone numbers?
