<prompt> Human: Hey all! I was just wondering how common it is for a credit limit to be raised without notice. I got the Chase Amazon card back in March, and had a credit limit of 2000, and then noticed on my last statement that it had gone up to 4000, without my asking, and without my receiving notice.Is this common?  <response>: This is normal. In my experience, it has meant Oh you arent destroying your finances with the credit card, lets increase your limit and make it more tempting. In other words, youre doing a good job increasing your credit score. Keep it up.
