Answer:
The Medical Information Bureau
Step-by-step explanation:
The Medical Information Bureau, established in 1902 has the responsibility of holding in their database, and crosschecking the past information records of applicants and determining if there are any errors or irregularities in documentation. They make this information available through a code so as to ensure the maintenance of privacy.
So, when an Insurer wants to crosscheck the information given in an insurance application, with previous insurance applications by the same applicant, the right place to go to would be the Medical Information Bureau, because they have the database.
