Some banks hand out higher limits than others, even if you give them the same information and your credit score is the same.
Wells Fargo gave me $5k way back when but now I'm at $15k. They've always been the best at slowly increasing my limit.
FNBO gave me $15k to start.
Discover gave me $12k but will not give me more. Wifey got $18k even though my credit score is a bit higher (she's 770 ish, I'm 811).
Bank of America got me at $10k. Started at $8,500. They're a little more stingy but not too bad.
Capital One gave me $3k for one card and $7k for Quicksilver. They can be a little stingy. Had them for years. Basically want credit in the hands of folks that will always carry a balance and only pay the minimum every month.
Citi got me at $12k. Similar to Discover, they don't seem interested in giving me more which is fine. I'd either need an increase in HHI probably into the $250k+ range or to start running utilizing for more than Netflix payments.
US Bank is the stingiest of all. Gave me $2k...highest household income and credit score I've ever had when I applied.
Target RedCard is $8k...good for groceries and saving 5%, then paying it off immediately.
Best Buy is $5k. Good for buying the latest video games, consoles, new laptops...get $5 back for every $20 I spend (maybe $25). Adds up quick with electronics.
