Multi-State National Criminal Database is a data file of over 38 million Offender records, including felony conviction information, state department of corrections records, and misdemeanor information. Most states records are updated on a monthly basis. The file also contains over 8 million alias names and nearly 68 million offenses. This search is done through multi-state databases maintained by many different sources. Information will vary. It is important to note that multi-state criminal searches do not include all criminal records nationally and the information is not always updated regularly. It is recommended that if a multi-state criminal search is run, it should be done in conjunction with county criminal searches. Typographical, data entry and/or court filing errors can cause accuracy issues. Also, running a partial or “nickname” (i.e. running Bob instead of Robert) can create accuracy issues. If “hits” are found on the Multi-State National Criminal Database, the law requires information to be verified directly through the court of records. Additional cost can apply.
