First, let me point out that a "blacklist" is an informal term. Chase doesn't actually have an actual "blacklist" that they work off of. Just based on stories and data in discussions and so forth, we can kind of see trends where they will not issue cards to people who have certain things in their histories.
That said, I'm pretty much on Chase's BL. I burned them about 6 years and 10 months ago for about $5k (scheduled to drop off in about 2 months). I have tried a number of times and the analysts have hinted strongly that I could get approved for a card once the item drops off my record. I actually had a recon a couple of months ago (so a little more than 6.5 yrs) and the analyst said he would recommend me for approval, but ultimately I was declined most likely for too many new accounts. Chase likes less than 5/24, I had about 25/24, so even though I may have cleared the BL hurdle, I'm still a tough approval for them currently.
Anyhow, back to the original question. I was able to open a checking account with Chase about a year ago even though all indicators would show that I was BL from their CC products at the time. They had a hefty account opening bonus and I was able to get that. Highly recomment going for this free money if you're thinking about opening a checking account with Chase.
Meanmchine, if you are blacklisted for CC CO, Chase will allow you to have a checking account. They will even allow you to be an AU. But until they forgive you, you will be unable to get a CC. I CO'd $15K with Chase. Fell of in June. I app'd back in Nov. My internal EX Chase credit score was 737, but I was denied. DECISION: Delinquency or other derogatory relationship with our bank. I used a HP to find out. Good luck! I hope they're memory is shorter in your situation than it was mine.
I never paid nor was I sued. I've heard that they're more likely to let you back in if you've paid your debt. With so many other options out there and the fact that I spent 7 years in debtor's prison, I'll just pass on Chase.
