What is an "OCA" number?

The OCA number is a field for the requesting agency to use for internal needs. 

OCA stands for "Originating Case Agency". 

Sometimes the Request For Live Scan Service Form may have this field listed as "Your Number" or "Facility Number". 

This field in the live scan system is only required by specific agencies. (i.e. Department of Social Services - A0448). 

Certifix uses this field to identify Certifix Billing Accounts.
