Buffering and Deduplication of Credit Card Inquiries Research Project

Buffering and Deduplication of Credit Card Inquiries Research Project

It is a little known fact that most credit card inquiries, taken in a short period of time, will be counted as 1 for FICO scoring purposes.

 

Most credit card inquiries are scored the same as mortgage inquiries by FICO. The inquiries are not be scored by FICO for 31 days. Then, any inquiries taken within a short period of time will be scored­ as one by FICO. Therefore, it is possible to take a large number of inquiries and only lose as few as 3 points. Theoretically, this will apply to any inquiries taken within 45 days for FICO 8. However, my research has only focused on inquiries taken within a period of 1 week. 

 

Inquiries from BofA, Barclays, Synchrony, Capital One, virtually all Credit Unions, probably Amex and others will be combined for scoring purposes.

 

This means that by strategically planning your app sprees, it is possible to lose only a few points. For example, an app spree consisting of BofA, Barclays, Synchrony and several Transunion pulling Credit Unions could only cost you 3 points.

 

There is no need for the shopping card trick. You can get better cards with little point loss.

 

The delayed scoring of inquiries is referred to as buffering by FICO.

The scoring of multiple inquiries as one is referred to as deduplication by FICO. The commonly used term is deduped.

 

Chase, Citi and FNBO pull Bankcard Enhanced inquiries. It is unlikely that those inquiries will be combined. 

 

I recently took 4 CLI hard pulls and on credit card app hard pull. There was no change in my scores for 31 days. At that time the hard pulls were scored as 1. The table below shows the results:

Re: FICO Will Combine Hard Pulls for Your Next App Spree!

Not trying to correct your tables here or anything, but wouldn't we need to know your utilization, and what each increase resulted in?  You had so many changes was there a measurement afterwards to show your scores when your reports reflected the increases?

 

Plus your scores were so close to perfect anyway, you probably have some really old accounts or micromange your utilization.  For me, no matter what my scores are kinda stuck but that is because of opening so many cards so often and having a 5 year old late payment error on a student loan.

Good post for new members, pretty sure all of our seasoned members know this. Got all on one pull: 2 chase cards (1 ex pull), 2 cap one cards (all bureaus, 1 pull), and 2 boa cards (1 tu pull)

Can't do it with Capital One anymore - they will only approve one card every 6 months now. Just so new members know. So those 3 pulls from Capital One can only get you one card.

Overall utilization and per card utilization is always under 1%. My scores are very stable. I was careful to make sure that the tables show when the score drops occured.

Good to know.  I always knew this to be true of inquiries related to installment loans, but didn't know it was also the case for revolvers.

 

In terms of scoring, this information could be a reason why someone should consider a "spree" over applying for the same amount of cards over several months.

This isn't about getting multiple cards on one pull. This is about buffering and deduplication. What this refers to is the possibility of taking 10, 20 or 50 HPs, having them scored as 1, and only losing 3 points.

Exactly.

Re: FICO Will Combine Hard Pulls for Your Next App Spree!

I'm curious on how you are determining that the inquiries are being scored as one.  Just because your scores didn't drop that much?  I'd really like know where you're getting your info from.  Certainly cant be just from your own personal experiences because everyone's credit file is vastly different.

 

Also it is very misleading to suggest to other posters, especially new ones that taking 50 inquiries is only to damage your score a few points.  Won't happen that way especially if new accounts are created and even if all inquiries resulted in declines I don't believe that anyone would see just a few point drop.

5 HPs result in no score drop for 30 days. 31 days later there is a small score drop, reflecting only 1 HP. That is how buffering a deduplication works. I've presented multiple repeated examples.  If you read the charts it is very clear.

 

When HPs are deduplicated they are scored as 1. I've never heard of any limit to the number of inquiries that can be deduplicated. So certainly 50 HPs would likely be deduplicated. I used 50 as an example to explain that this is not about getting multiple cards for 1 HP. It is, however, accurate.
