Why is Column Level Encryption not applied for fields of the Phone Number data type

[Suhyeon Lee]

Why is Column Level Encryption not applied for fields of the Phone Number data type, even though it is a String Extend Type?

Is there a way to apply this through system configuration changes or development?

I have already referred to the documents below.

Supported configuration information

• The following field types can be encrypted:
  • Attachments

  Note: More field types are available in Column Level Encryption Enterprise. See Column Level Encryption Enterprise for details.

Hi @Suhyeon Lee 

Phone Number fields in ServiceNow are a specialized type of string field that includes additional functionality, such as formatting and validation. This additional functionality may interfere with the encryption and decryption processes. This could be the possible reason for exclusion in my perspective.
