Report the issue to your financial institution and request number change
Contact the financial institution that issued your account as soon as possible and ask them to change your account number.
The sooner the number is changed, the lower the risk of fraudulent activity.
Some financial institutions require timely notification as a condition of waiving your liability for fraudulent charges.
2.
Check for unauthorized activity with help from your financial institution's fraud department
Review your financial account for unauthorized activity such as charges, change of billing address, addition of authorized shipping addresses, new card requests, etc. by checking your account online or by examining your most recent paper account statements.
Ask your financial institution's fraud department to help you audit your account for unauthorized activity that may not yet be visible in your online account detail or paper statements (pending charges or requests.)
3.
Reverse any unauthorized activity and file a report with local law enforcement
If unauthorized activity is found, immediately ask your financial institution's fraud department to reverse it and file a report with your local police. Retain a copy of the police report to document the situation should you need to contact creditors or credit reporting agencies.
