The

masking

task masks a phone number without changing the format of the original phone number. For example, the

masking

task can mask the phone number

(408) 382-0658

as

(607) 256-3106

.

The source data can contain numbers, spaces, hyphens, and parentheses. The following examples are valid formats of input phone numbers:

08040208950

080-4020-8950

(080)-4020-3797

(080)-(4020)-(3797)

(080)-4020-3797

(080) 4020 (3797)

Alphabetic and special characters are not masked. The following examples of input phone numbers are not in valid formats:

x80-4020-8950

x80-4020-x768

x80-4020/789

To support additional formats, you need to make changes to the Data Masking transformation. If the input data contains alphabetic and special characters, the task replaces with default values from the defaultValue.xml file.

You can configure repeatable output when you mask phone numbers. You must select

Repeatable

and enter a seed value.
