Generator	Description	Supported features
Address API: AddressGenerator	Generates replacement values for U.S. mailing addresses. You select the address component or format for the replacement values.

If there is no relationship, uses the Categorical generator.	Linkable - linking is required Privacy ranking: 3
Alphanumeric String Key API: AlphaNumericPkGenerator	Generates unique alphanumeric strings of the same length as the input. For example, for the origin value ABC123, the output value is a six-character alphanumeric string such as D24N05.
