Grats on your double CLIs
If an account is opened in a bucketed condition it is always bucketed, its why one should just open a new account with Cap-1 if they want to deal with them after they have a clean file.
Every single Capital One card is bucketed, even the super prime customers don’t start in their highest bucket (there are no accounts less than 5 years old in it).
Some cards are more bucketed than others and there seems to be no real concrete reason for why one profile gets out of the starter bucket like mine that started at $300 and is now $8250. Just use the card and if CLIs aren’t what you want, start checking for prequals for second cards. Capital One can be extremely generous with limits on those.
Congrats on your successes!
