Your credit score is in danger of being affected in negative ways in case of identity theft and it would take time to remove any fraudulent purchases from your record. If your identity has been stolen in a fraudulent act, you should ask the credit bureaus to place a "fraud alert" on your record. For identity theft, you can ask the credit bureau to send you two copies of your of your credit report. They should be sent to you free after you have sent in a police report on the identity theft.
