If you mean MDC1200 data bursts (ahem...'Squaaawk'), then there are no scanners currently capable of displaying the IDs. There are, however, external decoders and certain newer and appropriately optioned Motorola radios that will readily decode MDC1200.
There's a hobbiest that has apparently developed some software (in C programming language, IIR) that will decode the bursts as well. This is being actively discussed on the (currently out-of-order) Batlabs discussion board.
