Generate phone number

The Generate phone number masking activity allows you to generate phone numbers for specific countries.

Table of contents


To use the Generate phone number masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, select the property you want to mask. Next, enter the country code of the country you want the generated phone numbers to be related to. Note that the country code needs to be a string value.


In this example we want to generate US-related phone numbers for the Customer table. First we place the Customer masking activity into opened Package.xaml and put the Generate phone number masking activity within it. Once placed, we select the Phone property that we want to mask. Next, we enter "US" as the country we want the company names to be generated for.
