"The materials did not include any Social Security numbers or other financial information," read an email sent out Wednesday to the 940 enrolled students.
"As a precaution, however, you may want to monitor account statements and free credit reports for signs of suspicious activity."
Students were given the names, phone numbers and website addresses of major consumer reporting agencies as part of the email.
The information included student names, cellphone numbers, email addresses, birth dates and emergency contact information an on-call staff member would use in case of a medical crisis or other emergency situation, said Maylou Ferry, vice president for communication and marketing for the college.
"The tote bag containing the emergency information for students was stolen from the vehicle of a professional staff member while they were away from Claremont," she said.
A report was filed with the Anaheim Police Department, Ferry said.
The paper list is maintained in case of power outages where electronic information is inaccessible, officials said.
Students who may have any questions or concerns can call the Dean of Students office at 909-621-8277.
