What race code should be used to search all records?

The race code designated for searching all records is 'U.' This code stands for "unknown" and is used when the specific race of an individual is not known or is not applicable to the search parameters. The ability to search with this code allows law enforcement and other agencies to capture a wider range of records, ensuring that no relevant information is overlooked simply due to incomplete demographic information.

Using 'U' helps maintain comprehensive search results, which is particularly important in situations where quick access to information is essential, such as during emergency response or investigations. The other codes, while applicable for specific races, limit the search to particular demographic categories and could inadvertently exclude important records that don't match those specified categories.
