True. This inquiry collapsing behavior is a feature of recent iterations of two popular models: FICO (8,9,10) and VantageScore (2.0,3.0).
Note however that:
It only works for certain types of debt. For example, FICO8+ includes auto, student, and mortgage. VantageScore2+ includes utilities, auto, mortgage. No model includes revolving accounts like credit, retail, or charge cards.
The inquiry collapsing behavior only occurs within a single asset class. For example, FICO8+ would collapse simultaneous shopping for student loans, car loans, and mortgages into 3 inquiries, not 1.
The shopping period varies. FICO8+ ignores same-class inquiries for 30 days and collapses same-class inquiries within a 45-day window. VantageScore2+ does the same but only within a 14-day window.
Bonus hack: Certain banks also routinely collapse/reuse inquiries for same-day applications, permitting additional applications “for free,” which can be useful if you are denied your first choice and have a fallback in mind or if you are instantly approved for one product and want to try for another.
I was under the impression that many hard inquiries in a small time frame was ignored because it means you’re shopping for a loan.
Having a single hard enquiry every so often would mean you’re needing to keep borrowing money for some reason.
