Costco Wholesale Corporation Your Privacy Rights
(United States and Puerto Rico)

Last Updated January 1, 2020

This Privacy Policy explains how we collect, use and disclose personal information about you. This Privacy Policy applies to Costco Wholesale Corporation’s United States (US) and Puerto Rico subsidiaries ("Costco," "we," “our” or "us").


This Privacy Policy applies when you access or use our websites or mobile applications that link to this Privacy Policy, become a Costco member, shop at our warehouses, contact our customer service teams, or otherwise interact with us (collectively, the “Services”). This Privacy Policy does not apply to any Services or other websites that display or reference a different Privacy Policy. Personal information you provide or we collect from Costco’s warehouses, websites or services outside of the US and Puerto Rico is governed by the privacy policies of the Costco entities in those other countries.


We may change this Privacy Policy from time to time. If we make changes, we will notify you by revising the date at the top of this policy. In some cases, we may provide you with additional notice (such as a statement on our website). Please review this Privacy Policy from time to time so you understand our privacy practices and your choices regarding how we use your personal information.


1. Information We Collect

Information You Provide to Us

We collect information directly from you. For example, we collect information when you sign up for or renew your Costco membership, make a purchase, or register for an online account. We collect information when you sign up to receive news, notifications, or other communications from us. We also collect information when you request customer support; engage with us on social media; fill out a form; or participate in a survey or promotion. The types of information we collect directly from you may include:
  • Identification information, such as your name, title, membership card photo, date of birth, identity document (e.g., driver’s license, passport or tax identification number), employer name if you sign up for membership via your employer, and your Costco membership number.
  • Contact information, such as your mailing address, email address, and phone number.
  • Demographic information, such as your age and gender.
  • Payment information, including your payment card information and billing address.
  • Information necessary for us to provide Services, such as photographs for processing with Costco Photo Center, travel documents, etc.

Information We Collect Automatically

We automatically collect information about you when you access or use our Services or do business with us. For example, we collect:
  • Purchase Information. When you make a purchase or return, we collect information about the transaction. This may include product details, purchase price, date, tender type and location of the transaction. It may also include account notes about the transaction.
  • Browsing and Usage Information. When you use our internet-based Services, some information is collected automatically, including as described in the Cookies and Similar Technologies section below. For example, when you visit our websites, our web servers automatically log your computer's operating system, Internet Protocol (IP) address, access times, browser type and language, the website you visited before our site, and your activity on our websites. We also collect information about what products and services you browse or express an interest in and we track your activity on our Services and websites where our advertising is served, such as which pages and ads you view or click on.

If you enable location services on your device, we collect more precise geolocation information. This lets us serve you the location of nearby warehouses, location-based ads, notify you of products and services available in your area, and provide location-based services or functions. You can opt-out of the collection of precise geolocation information at any time (see Your Choices below for details).
  • Video and Images from Warehouse Cameras. We use cameras in and around warehouses to capture video and images. We may use these videos and images for security, fraud, loss prevention, law enforcement or incident reporting, or other operational purposes, such as analyzing traffic patterns.
  • Call Recordings and Chat Transcripts. We record and store telephone calls and chat transcripts for a period of time when you interact with our customer or technical support personnel.

Information We Create or Generate

We infer new information from the information we collect, including using automated means to create or generate information about your likely preferences, interests, or other characteristics (“inferences”). For example, we may infer your city, state, and country location based on your IP address or zip code. We may also infer products or services that may interest you based on your prior purchases with us, our vendors, or other companies you engage with.

Information We Receive from Other Sources

We may collect information about you from other sources that we may combine or link with information we have about you. We may combine information that we have collected offline with information we collect online. In addition, we may collect information from:

4. Cookies and Similar Technologies

We use cookies, web beacons, and similar technologies to operate our websites and online services and to help collect data.

Cookies are small text files placed on your device to store data that can be recalled by a web server in the same domain that placed the cookie. The text in a cookie often consists of a string of numbers and letters that uniquely identifies your device, but it can contain other information as well.

We use cookies on our websites to store your preferences and settings, enable you to sign-in, provide interest-based advertising, combat fraud, analyze how our products perform, and fulfill other legitimate purposes.

Our web pages may also contain electronic images known as web beacons (also called pixel tags or clear gifs) that we use to count users who have visited those websites, and gather usage and performance data. We also include web beacons in our promotional email messages or newsletters to determine whether you open and act on them.

Our websites may include web beacons and cookies from our service providers, such as site analytics. In other cases, it is because our web pages contain content or ads from other companies, such as videos, news content, or ads delivered by other ad networks (see Advertising, Services Provided by Others; Interest-Based Advertising below). Because your browser connects to web servers operated by other companies to retrieve that content, those other companies are able to set or read their own cookies on your device and may collect information about your online activities across websites or online services.

The analytics providers we use include the following:

Company/ Service Purpose(s) Privacy Notices Manage Settings (opt-out)
Adobe Advertising, analytics https://www.adobe.com/privacy/policy.html https://www.adobe.com/privacy/opt-out.html
Google Analytics (Costco Travel only) Analytics https://policies.google.com/technologies/partner-sites https://tools.google.com/dlpage/gaoptout
To opt-out from these companies’ collection or use of certain types of data, and to learn more about their privacy practices, click on the links above. You can use browser controls to limit how the websites you visit are able to use cookies. Instructions for blocking or deleting cookies may be available in each browser's privacy or help documentation. Please be aware that if you choose to block cookies, certain website features that depend on cookies may no longer function. Choices you make regarding cookies are specific to your browser and device. If you choose to delete cookies, settings and preferences controlled by those cookies, including your opt-out and advertising preferences, may be deleted and may need to be recreated.

Mobile Advertising ID Controls. iOS and Android operating systems provide options to limit tracking and/or reset the advertising IDs.

Email Web Beacons. Most email clients have settings which allow you prevent the automatic downloading of images, which will disable web beacons in the email messages you read.

5. Other Sites; Social Media and Social Sharing Features

The Services may link to or integrate with content or sites operated by other companies. These companies may offer you goods and services or provide services to Costco, such as product information, product or service reviews, or marketing or analytics services. In general, any information you provide on other companies’ sites is provided directly to that company and is subject to its privacy practices.

The Services may offer social sharing features that let you share information on your social media accounts such as through the Facebook “Like” button. When you use these features, you are sharing information with your friends or the public, depending on your social media account privacy settings. For information about data collection and use in connection with social sharing features, please read the privacy policies of the companies that provide these features. Any information you post or disclose on message boards, chat, profile pages, blogs and other services, including our Social Media Pages, may be public and viewable by other users. The use of shared information is governed by the social media provider’s privacy policy.

6. Advertising Services Provided by Others; Interest-Based Advertising

We use other companies to collect analytics information and serve advertisements on our behalf. When you visit our website or use our mobile applications, we and these companies may collect information from cookies, pixel tags, device identifiers, and other technologies about your browsing activity and use of the Services, websites, and apps (see Cookies and Similar Technologies for more information). Costco and our vendors may use this information to deliver advertising and content targeted to your interests.

  • Interest-Based Advertising. Some of these companies deliver advertising and content based on your activity across websites and over time. This is interest-based advertising.
  • Opting Out. In accordance with the Digital Advertising Alliance Self-Regulatory Principles for Online Behavioral Advertising, if you do not want to receive interest-based advertising, you may opt out by visiting www.aboutads.info/choices.
  • Device-Based Opt Out Features. Your device may also include features that allow you to opt out of having certain information collected through apps used for interest-based advertising purposes.
  • Scope of Opt-Out. If you opt out of interest-based advertising, you may still see ads that are less tailored for you as you browse the internet.
  • Do Not Track. While we strive to offer you choices when you use our Services (as described below), because of a lack of standardization regarding Do Not Track signals we are not able to receive or honor “Do Not Track” signals from your web browser at this time. Instead, you can use the range of other tools to control information collection and use, including the cookie, analytics, and advertising controls described above.

7. Your Choices

We provide choices about how we collect, use and share information about you. The choices you make will not apply to your household or any affiliate members associated with your membership account.

9. Protection of Personal Information

We aim to take reasonable steps to help protect your personal information. Unfortunately, no data transmission or storage system can be guaranteed to be 100% secure and therefore we are unable to guarantee the security of your personal information. If you have reason to believe that your interaction with us is no longer secure, please let us know (see “Contact Us” below).

10. California Privacy Rights

If you are a California resident, beginning January 1, 2020 you have the right to make the following requests with respect to your personal information under the California Consumer Privacy Act (CCPA):
  • Access You have the right to request that we disclose to you the personal information we have collected, used, disclosed or sold about you in the previous 12 months. You may submit an access request here.
  • Deletion You can request that we delete your personal information that we collected from you to the extent required under CCPA and subject to certain exceptions. We retain personal information to service your membership, to comply with applicable laws and regulations and other permissible purposes. That means we may not be able to delete all of your personal information. You may submit a deletion request here.
  • Right to Opt-Out You have the right to request to opt-out from future “sales” of your personal information. To do so, please visit our “Do Not Sell My Information” page. The law defines “sale” very broadly to include simply making data available to third parties in some cases. We let advertising and analytics companies collect IP addresses, and cookie IDs through our sites and apps when you use our Services. We also disclose personal information to the companies that provide products and services to our members for their own marketing purposes as described above (see “Sharing of Information” section above). If you do not wish for us to “sell” your personal information to other companies as defined under the CCPA, you can opt out and exercise your Do Not Sell My Information rights by (a) checking the opt-out box on membership applications; (b) following the opt-out instructions on renewal notices; (c) contact us using the methods above; or (d) make your Do Not Sell request by visiting our “Do Not Sell My Information” page.
After you submit your Do Not Sell request, we may continue to share some personal information with our suppliers (acting as our service providers) that do not constitute “sales” to help us perform advertising-related functions such as, but not limited to, measuring the effectiveness of our ads, managing how many times you may see an ad, reporting on the performance of our ads, ensuring services are working correctly and securely, providing aggregate statistics and analytics, improving when and where you may see ads, and/or reducing ad fraud. Any opt out choices you make will only apply to the specific email address that you provide when making the request.

You may designate an authorized agent to make requests on your behalf to exercise your rights under the California Consumer Privacy Act. Before accepting such a request from an agent, we will require the agent to provide proof you have authorized that person to act on your behalf, and we will need you to verify your identity directly with us. Further, to provide or delete specific pieces of personal information we will need to verify your identity to the degree of certainty required by law. You must use the Third Party Authorization form available on our website to authorize third parties to make an access or deletion request on your behalf. Finally, you have a right to not be discriminated against for exercising rights set out in the CCPA.

For assistance making a California access or deletion request, please call 1-800-605-3364

We may deny certain requests, or fulfill a request only in part, based on our legal rights and obligations. For example, we may retain personal information as permitted by law, such as for tax or other record keeping purposes, to maintain an active account, and to process transactions and facilitate customer requests. We will not include employment related information in fulfilling your request.
