Marriott International

Marriott has taken measures to investigate and address a data security incident involving the Starwood guest reservation database. This site has information concerning the incident, answers to guests’ questions and steps you can take.

30 November 2018 Updated: 22 December 2018

Marriott values our guests and understands the importance of protecting personal information. We have taken measures to investigate and address a data security incident involving the Starwood guest reservation database. The investigation has determined that there was unauthorized access to the database, which contained guest information relating to reservations at Starwood properties on or before September 10, 2018. This notice explains what happened, measures we have taken, and some steps you can take in response.

On September 8, 2018, Marriott received an alert from an internal security tool regarding an attempt to access the Starwood guest reservation database. Marriott quickly engaged leading security experts to help determine what occurred. Marriott learned during the investigation that there had been unauthorized access to the Starwood network since 2014. Marriott recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it. On November 19, 2018, Marriott was able to decrypt the information and determined that the contents were from the Starwood guest reservation database.

Marriott has not finished identifying duplicate information in the database, but believes it contains information on up to approximately 500 million guests who made a reservation at a Starwood property. For approximately 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest (“SPG”) account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences. For some, the information also includes payment card numbers and payment card expiration dates, but the payment card numbers were encrypted using Advanced Encryption Standard encryption (AES-128). There are two components needed to decrypt the payment card numbers, and at this point, Marriott has not been able to rule out the possibility that both were taken. For the remaining guests, the information was limited to name and sometimes other data such as mailing address, email address, or other information. Marriott reported this incident to law enforcement and continues to support their investigation. We have already begun notifying regulatory authorities.

Marriott deeply regrets this incident happened. From the start, we moved quickly to contain the incident and conduct a thorough investigation with the assistance of leading security experts. Marriott is working hard to ensure our guests have answers to questions about their personal information with a dedicated website and call center. We are supporting the efforts of law enforcement and working with leading security experts to improve. Marriott is also devoting the resources necessary to phase out Starwood systems and accelerate the ongoing security enhancements to our network.

Frequently Asked Questions

These Frequently Asked Questions May Be Supplemented From Time to Time

On September 8, 2018, Marriott received an alert from an internal security tool regarding an attempt to access the Starwood guest reservation database. Marriott quickly engaged leading security experts to help determine what occurred. Marriott learned during the investigation that there had been unauthorized access to the Starwood network since 2014. Marriott recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it. On November 19, 2018, Marriott was able to decrypt the information and determined that it was from the Starwood guest reservation database.

The information copied from the Starwood guest reservation database over time includes information about guests who made a reservation at a Starwood property, including names, mailing addresses, phone numbers, email addresses, passport numbers, Starwood Preferred Guest (“SPG”) account information, dates of birth, gender, arrival and departure information, reservation dates, and communication preferences. The combination of information varies by guest. For some individuals, the information copied also included payment card numbers and payment card expiration dates, but the payment card numbers were encrypted using Advanced Encryption Standard encryption (AES-128). There are two components needed to decrypt the payment card numbers, and at this point Marriott has not been able to rule out the possibility that both were taken.

After receiving the internal security alert, we immediately engaged leading security experts to help us determine what occurred. We quickly installed additional security tools to help us gather facts and reported the incident to law enforcement. Forensic investigative work is painstaking, and our internal and external security teams have been working nonstop to investigate the incident, implement additional security measures, and address what was found. We recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it. On November 19, 2018, Marriott was able to decrypt the information and determined that the contents were from the Starwood guest reservation database. We then immediately began taking steps to notify our guests and regulatory authorities.

For approximately 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest (“SPG”) account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences.

There are two components needed to decrypt the payment card numbers, and at this point Marriott has not been able to rule out the possibility that both were taken. For the remaining guests, the information was limited to name and sometimes other data such as mailing address, email address, or other limited information.

The guest reservation database that is involved was only used for Starwood reservations. Marriott uses a separate reservation system that is on a different network.

Starwood brands include: W Hotels, St. Regis, Sheraton Hotels & Resorts, Westin Hotels & Resorts, Element Hotels, Aloft Hotels, The Luxury Collection, Tribute Portfolio, Le Méridien Hotels & Resorts, Four Points by Sheraton and Design Hotels that participate in the Starwood Preferred Guest (SPG) program. Starwood branded timeshare properties (Sheraton Vacation Club, Westin Vacation Club, The Luxury Collection Residence Club, St. Regis Residence Club, and Vistana) are also included.

Starwood’s operation of its reservation database is also performed on behalf of other companies including those that independently own hotel properties, that manage hotel properties as a franchisee of Starwood and that offer timeshare and other vacation ownership interests and programs under a license agreement with Starwood.

Starwood operates its reservation database to independently process reservations for guests of the Starwood properties that book their stay via an Online Travel Agency or other company that acts as an agency, broker or exchange service.

The investigation only identified unauthorized access to the separate Starwood network.

Marriott deeply regrets this incident happened. From the start, we moved quickly to contain the incident and conduct a thorough investigation with the assistance of leading security experts. Marriott is working hard to ensure our guests have answers to questions about their personal information with a dedicated website and call center. We are supporting the efforts of law enforcement and working with leading security experts to improve. Marriott is also devoting the resources necessary to phase out Starwood systems and accelerate the ongoing security enhancements to our network.

You may choose to enroll in WebWatcher if it is available in your country/region.

We want you to be confident that the email notification you may receive is from Marriott. The email will come from the following email address: starwoodhotels@email-marriott.com.

If you are a resident of Massachusetts or Rhode Island, note that pursuant to Massachusetts or Rhode Island law, you have the right to file and obtain a copy of a police report. You also have the right to request a security freeze.

If you are a resident of West Virginia, you have the right to ask that nationwide consumer reporting agencies place "fraud alerts" in your file to let potential creditors and others know that you may be a victim of identity theft, as described below. You also have a right to place a security freeze on your credit report, as described below.

Fraud Alerts: There are two types of fraud alerts you can place on your credit report to put your creditors on notice that you may be a victim of fraud—an initial alert and an extended alert. You may ask that an initial fraud alert be placed on your credit report if you suspect you have been, or are about to be, a victim of identity theft. An initial fraud alert stays on your credit report for at least 90 days. You may have an extended alert placed on your credit report if you have already been a victim of identity theft with the appropriate documentary proof. An extended fraud alert stays on your credit report for seven years. You can place a fraud alert on your credit report by contacting any of the three national credit reporting agencies.

Credit Freezes: You have the right to put a credit freeze, also known as a security freeze, on your credit file, free of charge, so that no new credit can be opened in your name without the use of a PIN that is issued to you when you initiate a freeze. A security freeze is designed to prevent potential credit grantors from accessing your credit report without your consent. If you place a security freeze, potential creditors and other third parties will not be able to get access to your credit report unless you temporarily lift the freeze. Therefore, using a security freeze may delay your ability to obtain credit.

There is no fee to place or lift a security freeze. Unlike a fraud alert, you must separately place a security freeze on your credit file at each credit reporting company. For information and instructions to place a security freeze, contact each of the credit reporting agencies at the addresses below:

To request a security freeze, you will need to provide the following information:

  1. Your full name (including middle initial as well as Jr., Sr., II, III, etc.)
  2. Social Security number
  3. Date of birth
  4. If you have moved in the past five years, provide the addresses where you have lived over the prior five years
  5. Proof of current address such as a current utility bill or telephone bill
  6. A legible photocopy of a government issued identification card (state driver's license or ID card, military identification, etc.)
  7. If you are a victim of identity theft, include a copy of the police report, investigative report, or complaint to a law enforcement agency concerning identity theft

The credit reporting agencies have one business day after receiving your request by toll-free telephone or secure electronic means, or three business days after receiving your request by mail, to place a security freeze on your credit report. The credit bureaus must also send written confirmation to you within five business days and provide you with a unique personal identification number (“PIN”) or password or both that can be used by you to authorize the removal or lifting of the security freeze.

To lift the security freeze in order to allow a specific entity or individual access to your credit report, or to lift a security freeze for a specified period of time, you must submit a request through a toll-free telephone number, a secure electronic means maintained by a credit reporting agency, or by sending a written request via regular, certified, or overnight mail to the credit reporting agencies and include proper identification (name, address, and Social Security number) and the PIN or password provided to you when you placed the security freeze as well as the identity of those entities or individuals you would like to receive your credit report or the specific period of time you want the credit report available. The credit reporting agencies have one business day after receiving your request by toll-free telephone or secure electronic means, or three business days after receiving your request by mail, to lift the security freeze for those identified entities or for the specified period of time.

To remove the security freeze, you must submit a request through a toll-free telephone number, a secure electronic means maintained by a credit reporting agency, or by sending a written request via regular, certified, or overnight mail to each of the three credit bureaus and include proper identification (name, address, and Social Security number) and the PIN number or password provided to you when you placed the security freeze. The credit bureaus have one business day after receiving your request by toll-free telephone or secure electronic means, or three business days after receiving your request by mail, to remove the security freeze.

Fair Credit Reporting Act: You also have rights under the federal Fair Credit Reporting Act, which promotes the accuracy, fairness, and privacy of information in the files of consumer reporting agencies. The FTC has published a list of the primary rights created by the FCRA (https://www.consumer.ftc.gov/articles/pdf-0096-fair-credit-reporting-act.pdf), and that article refers individuals seeking more information to visit www.ftc.gov/credit. The FTC’s list of FCRA rights includes:

  • You have the right to receive a copy of your credit report. The copy of your report must contain all the information in your file at the time of your request.
  • Each of the nationwide credit reporting companies – Equifax, Experian, and TransUnion – is required to provide you with a free copy of your credit report, at your request, once every 12 months.
  • You are also entitled to a free report if a company takes adverse action against you, like denying your application for credit, insurance, or employment, and you ask for your report within 60 days of receiving notice of the action. The notice will give you the name, address, and phone number of the credit reporting company. You are also entitled to one free report a year if you’re unemployed and plan to look for a job within 60 days; if you are on welfare; or if your report is inaccurate because of fraud, including identity theft.
  • You have the right to ask for a credit score.
  • You have the right to dispute incomplete or inaccurate information.
  • Consumer reporting agencies must correct or delete inaccurate, incomplete, or unverifiable information.
  • Consumer reporting agencies may not report outdated negative information.
  • Access to your file is limited. You must give your consent for reports to be provided to employers.
  • You may limit “prescreened” offers of credit and insurance you receive based on information in your credit report.
  • You may seek damages from violators.
  • Identity theft victims and active duty military personnel have additional rights.
