MODAT is a 7-tone Automatic Number Identification (ANI) status system used by handheld radios. It provides unit ID and emergency statuses to receiving radio sets when transmitted. Transmitting the ANI-ID allows receivers and dispatchers to know who they are talking to, identify system abusers, identify emergency conditions and assign calls fairly. MODAT is a proprietary mode developed by Motorola. MODAT was available on the MT500, MX300 Series, Syntor, and MICOR mobiles, as well as the ASTRO series.

MODAT has 11 tones to choose from and transmits up to 7 tones in a burst right before radio transmission. MODAT supports 4-digit ID's and have a range from 0000-8999. Each tone has a length of 40ms. The bursts transmit right before a radio transmission.

MODAT was used by the Baltimore Fire Department and the Los Angeles Police Department for unit ID before they upgraded to digital trunking.
