Random Digits

Purpose

The Random Digits masking format generates random digits of length within a range. It pads to the appropriate length in a string, but does not pad when used for a number column. This format is a complementary type of Random Number, which is not padded.

Inputs

• Start Length: The minimum number of digits each masked value should have
• End Length: The maximum number of digits each masked value should have

Supported Data Types

• Character
• Numeric

Characteristics

• Supports Double-Byte Characters: Does not apply
• Combinable: Yes
• Deterministic: No
• Reversible: No
• Uniqueness: Yes, however, if you do not specify a sufficient length range, you can run out of unique values within the range.

Example

For a random digit with a length of [5,5], an integer from zero through 99999 is randomly generated and left padded with zeros to satisfy the length and uniqueness requirement.
