NOTE: Data Identifiers are legacy DLP features that will no longer be supported by the end of June 2025, it is recommended to use a classification-based approach for all your DLP use cases. To assist with migrating your DLP policies from Data Identifiers to Classification, refer to the Migration Guide.

Skyhigh CASB supports the following definitions, validation, and keyword information for U.S. driver's license number data identifiers. 

NOTE: Skyhigh CASB regex includes an extra backslash to conform with JSON string structure. Naked regex would have only one backslash, but regex in strings requires the extra backslash to be escaped. For more information, see https://www.regular-expressions.info/java.html.
