Common Methods of SSN Masking

Partial Masking

Only part of the SSN is displayed. For example, the first five digits (Area Number and Group Number) appear, while the last four digits are replaced with asterisks or Xs.

• Often used on documents where full SSNs are not needed for identification.

Full Masking

The entire SSN is obscured or replaced with asterisks or Xs.

• Used for maximum privacy protection.

• Prevents unauthorized access when the SSN is not required for verification.

Truncation

Only a portion of the SSN is visible. For example, the last four digits show while the rest are masked.

• Provides a balance between security and limited identification.

Why SSN Masking Matters

The Social Security Number is a critical piece of personal data. If exposed, it can be exploited for identity theft or fraud. Masking SSNs helps:

• Protect individuals from identity theft.

• Reduce the risk of fraud.

• Limit exposure of sensitive personal information during printing, mailing, or transmission.
