Unique record identifier Each record in ServiceNow is identified by a unique 32-character GUID (Globally Unique ID) called a sys_id. The same sys_id value will never be generated twice, ensuring every record created in every table in every instance of ServiceNow in the world has a unique identifying value. If two records have the same sys_id value, then one was copied to the other at the database level outside of the ServiceNow application. When created within the application, sys_id values are unique. The ServiceNow application and database should manage all operations on sys_id values. Typical end users do not see a record's sys_id and database administrators rarely use sys_id values. Note: A sys_id of -1 is the sys_id of a new record. Once the record is inserted, it will be given a new sys_id.
