I received a pre approval credit card offer in the mail from one of the large companies. The outside of the envelope was addressed to me. After opening the envelope I realized the letter and application inside were addressed to a completely different person and address. This being said, I assume the pre approval letter that had been meant for myself was also sent to someone else. Should I be concerned that my pre approval application could potentially be in the wrong hands even if it only has name, address and pre approval offer number on it? If any, what actions should I take in this situation? Other than notifying the company not to take an application under my name or application number (if this is even possible), are there any other precautions I should take? Or am I overreacting since additional personal information is needed to actually put through an application? I don't appreciate the carelessness that the company put forth. Thanks for any advice you can provide.
