Comes from a lender typically. Loan Verification is for those who need to have a certain number of good paid timely accounts in order to qualify for a particular program. If the auto loan is not being reported and you have paid as agreed (and you need it to be recognized by the mortgage company for approval) you can use the account as a reference during the loan process.
BTW - If a CU doesn't report to the CRAs why continue your relationship? I guarantee if you pay late they will report.
