Steps You Can Take To Protect Personal Information

Monitor Your Accounts

Under U.S. law, a consumer is entitled to one free credit report annually from each of the three major credit reporting bureaus, Equifax, Experian, and TransUnion. To order a free credit report, visit www.annualcreditreport.com or call, toll-free, 1-877-322-8228.

Consumers have the right to place an initial or extended “fraud alert” on a credit file at no cost. An initial fraud alert is a 1-year alert that is placed on a consumer’s credit file. Upon seeing a fraud alert display on a consumer’s credit file, a business is required to take steps to verify the consumer’s identity before extending new credit. If consumers are the victim of identity theft, they are entitled to an extended fraud alert, which is a fraud alert lasting seven years. Should consumers wish to place a fraud alert, please contact any of the three major credit reporting bureaus listed below.

As an alternative to a fraud alert, consumers have the right to place a “credit freeze” on a credit report, which will prohibit a credit bureau from releasing information in the credit report without the consumer’s express authorization. The credit freeze is designed to prevent credit, loans, and services from being approved in a consumer’s name without consent. However, consumers should be aware that using a credit freeze to take control over who gets access to the personal and financial information in their credit report may delay, interfere with, or prohibit the timely approval of any subsequent request or application they make regarding a new loan, credit, mortgage, or any other account involving the extension of credit. Pursuant to federal law, consumers cannot be charged to place or lift a credit freeze on their credit report. To request a credit freeze, individuals may need to provide some or all of the following information:

  • Full name (including middle initial as well as Jr., Sr., II, III, etc.);
  • Social Security number
  • Date of Birth;
  • Addresses for the prior two to five years;
  • Proof of current address, such as a current utility bill or telephone bill
  • A legible photocopy of a government-issued identification card (state driver’s license or ID card, etc.)
  • A copy of either the police report, investigative report, or complaint to a law enforcement agency concerning identity theft if they are a victim of identity theft.

Should consumers wish to place a credit freeze or fraud alert, please contact the three major credit reporting bureaus listed below:
