CODIS software enables local laboratories (LDIS) to feed DNA data electronically to SDIS, which is operated by a designated State laboratory. SDIS allows local laboratories in the same State to exchange DNA profiles.

Local laboratories cannot upload DNA profiles directly into NDIS. Instead, each State's CODIS laboratory has an administrator who is responsible for maintaining the data and information in SDIS. The State laboratory then inputs data into NDIS, which also receives DNA profiles analyzed by the FBI Laboratory. NDIS became fully operational in October 1998. As of May 2019, NDIS contained over 13 million profiles of those convicted of offenses, 3.5 million arrestee profiles and nearly 1 million forensic profiles.
