Close the accounts that you know or believe have been tampered with or opened fraudulently.
File a report with your local police or the police in the community where the identity theft took place. Get a copy of the report or at the very least, the number of the report, to submit to your creditors and others that may require proof of the crime.
File a complaint with the Federal Trade Commission. The FTC maintains a database of identity theft cases used by law enforcement agencies for investigations. Filing a complaint also helps us learn more about identity theft and the problems victims are having so that we can better assist you.
