1. A TransRisk Account Management Score is a score issued by TU that has the familiar score boundaries of 300-850 . This score is used as a general gauge of a consumer's overall credit worthiness, and is generally assumed to be TransUnion's implementation of the FICO scoring model.
2. Vantage Score is a model that was created by the three major US bureaus. This score has a score range of 500-990. Contrary to what Rory said, this score is indeed used by creditors, but please remember that no creditor uses only a canned score in their underwriting criteria.
3. An Auto Insurance score is a score that is used to estimate loss likelihood and loss severity for an auto insurer; in addition, some auto scores also attempt to predict one's liklihood to non-pay cancel their insurance policy.(Becuase your insurance premium is pre-paid for at least one month at a time, if you stop paying, you still have coverage until your premium equity runs out. At this point you have non-pay cancelled and are now uninsured by your carrier.) These scores are useful because your tier/company placement in insurance rating algorithms are heavily influenced by your insurance credit score as well as your current insurance information(do you have insurance now?Liability Limits?Did you tell the truth when asked what your liability limits were?).
4. Your scores typically shouldn't change daily, however there are cases where this can happen. If you have five consecutive days where new information is updated to your credit report(5 lenders reporting on different days) this is very possible. But if this continues for more than a week or two, I would contact their customer service and ask.
5. Your hard inquiries should
be removed then. Make sure you check to ensure the items on your report were handled properly. If not, contact your credit bureaus!
