Which transaction is utilized to obtain a Texas CCH and/or check for the existence of a criminal history in participating states?

The transaction used to obtain a Texas Criminal History (CCH) and to check for the existence of a criminal history in participating states is known as "QH, III." This transaction is specifically designed for accessing criminal history information, making it the appropriate choice for conducting thorough background checks where necessary.

The "QH, III" transaction allows authorized entities, such as law enforcement agencies or certain employers, to obtain detailed criminal history data. This is essential for ensuring the safety and security of various operations, particularly in fields where trust and security are paramount.

In contrast, the other transactions mentioned are not designated for checking criminal histories. They serve different purposes, which do not align with the conventional requirements for conducting thorough criminal background checks. This specificity is crucial when determining the relevance and appropriateness of transaction codes in the context of criminal history inquiries.
