Thanks to the power of technology, people around the world can easily link up and enjoy the experience of buying and selling with each other.

About Security

Tips for keeping your Mercari account secure Here are some tips you should follow to prevent other people from learning your ID and password and gaining unauthorized access to your account.

  • Use a strong password

    The more characters you use in your password, the stronger it gets. We recommend using a password at least 12 characters long. We also recommend using a mix of letters, numbers, and symbols in your password.

  • Use different passwords for different websites

    Using a unique password for each website/app is safer than reusing the same password multiple times.

  • Don’t forget to update your phone number

    If you aren’t sure how to check or update your phone number, see our guide to changing your verified phone number [Japanese].

  • Set a passcode to use when paying

    See our guide to setting up a passcode [Japanese]. If you’ve forgotten your passcode, see our guide to resetting your passcode [Japanese].

  • Lock your phone with a passcode

    Setting up a passcode to unlock your phone makes it harder for other people to use your phone when you’re not watching.

  • Watch out for logins and payments you don’t remember

    Check your email and notifications to see if there’s been any activity on your account that you don’t remember. We also recommend checking your Merpay usage history regularly to make sure there haven’t been any payments made without your knowledge. You can see your payment history by going to the Merpay tab and tapping “残高” (balance) and “ポイント” (points).

  • Stay away from suspicious websites/messages claiming to be Mercari

    If you receive any suspicious email messages claiming to be from Mercari, delete them immediately without opening the message or clicking on any links.

  • Remove your iD information when switching devices

    If you’re registered for iD payments on Merpay, we recommend removing the iD information from the Mercari app on your old device before starting to use your new device. To learn how to do this, see our guide to switching devices [Japanese].

  • Contact us if you lose your device

    If you lose a device logged into your Mercari account, contact us through the app and we’ll take action immediately so no one else can use your account. For more instructions, see our guide to contacting us about a lost device [Japanese].

  • Do not borrow or lend accounts

    Letting another person use your account is an infringement of Mercari’s Terms of Service. Mercari is not responsible for any trouble that may arise from doing so.

  • We recommend checking your login history regularly.

    You can check your account’s login history by going to the “マイページ” (My Page) tab, tapping “個人情報設定” (Personal Information Settings), and tapping “ログイン履歴” (Login History). Check if there’s been any activity on your account that you don’t remember.

About Accounts

If you notice unauthorized access to your account... If someone else logs in to your account without your knowledge, your personal information is at risk of being read by a third party.

  • Make sure your email address is safe

    Check to see if anyone else has accessed the email address you have registered on your Mercari account.

  • Make sure your social media accounts are safe

    Mercari offers the option to log in using a social media account (Facebook, Google). If you use a social media account to log in to Mercari, check to see if anyone else has accessed that account as well.

  • Change your password

    After making sure your registered email address (or social media account) is safe, change your Mercari password. For instructions, see our guide to changing your email address/password [Japanese].

If you notice unauthorized use of your account, contact us immediately.
Mercari uses AML monitoring and identity verification to keep our users safe and secure.

Overview

A secure system for buying and selling

Mercari provides its users with an environment where they can trade safely and securely. Mercari also uses an escrow payment system in order to guarantee a safe and reliable transaction service for everyone. In addition, buyers and sellers rate each other, so users can have peace of mind by checking the other party’s past reviews before deciding to engage in a transaction. Furthermore, we have a dedicated customer service system that responds to customer inquiries and monitors the service.

AI

Detecting Violations with AI

Mercari employs AI technology to automatically detect transactions that violate the terms of use. By combining this technology with extensive transaction data and item information data, the company aims to improve the accuracy of the detection systems and use them for a wider range of applications to provide an even safer and more secure environment for all users.
* Examples of items that violate terms of use: gaming accounts, counterfeits, medicine, etc.

Detecting Violations with AI
Government

Cooperating with Authorities

Mercari strives to provide a safe and secure service for all users by cooperating with public institutions and law enforcement. The aim is to work towards making not just Mercari, but the industry as a whole safer and more secure by participating in organizations such as the Council for Intellectual Property Protection (CIPP), EC Business Association, the Association of Consumer Affairs Professionals (ACAP), and the National Shoplifting Prevention Organization (NSPO). The company also takes a proactive role in exchanging opinions and drawing up guidelines.

Cooperating with Authorities
Customer Service

Dedicated customer service team

Mercari’s customer service system operates all day, every day, ensuring users can enjoy a safe and secure experience. Mercari monitors listings/transactions both manually and with automated detection systems to identify items that violate terms of use, making every effort to promptly remove any counterfeit/stolen goods.
These systems are based on copius data from item information and transactions as well as AI technology. We strive to improve their accuracy and expand their scope in an effort to create a secure environment for users.

Other Initiatives
  • Inhibiting fraud by enhancing identity verification

    Inhibiting fraud by enhancing identity verification

    Since February 2019, listers have been required to provide their personal information (address/full name/date of birth) when registering. A user’s sales balance cannot be withdrawn if the name registered does not match the name of the account for the balance transfer; this prevents fraudulent listings, such as stolen goods.

  • Ample compensation

    Ample compensation

    If a product arrives damaged or defective, we offer returns and compensation. Eligible items include unintentionally purchased counterfeit goods, items with a defect or damage not included in the description, and shipping fees for when an accident occurred with Mercari Shipping. Mercari has strategies to ensure normal items are safely delivered to the buyer, but in the event that a user purchases counterfeit or defective goods, they are also eligible for a return or compensation.

  • Awareness activities for adolescents and educators

    Awareness activities for adolescents and educators

    We hold educational activities across the country for middle school and high school students, as well as parents and teaching staff, where we teach them how to avoid trouble on marketplace apps, to ensure they can use Mercari with a sense of security.

Message

In 2012, I slung a backpack over my shoulder and set off to travel around the world. The most life-changing moments I experienced were in areas like South America and the Middle East—countries known as emerging nations. I saw before my eyes how people were trying to live more prosperously, as well as the reality of how limited resources were, and it opened my eyes to the issue that maybe not everyone in the world is able to live their lives in the same way.

When I returned home, smartphones had taken over Japan. I thought, “If we can use this technology to connect individuals all over the world and allow items to be easily bought and sold, maybe we can utilize the world’s resources more effectively and enrich the lives of people everywhere.” That thought was the basis for creating Mercari.

Since Mercari was established, we have grown our services while investing in both people and technology. But in order to become a service used throughout the world, we must genuinely take on our role as a public institution of society and work toward creating a circular economy, improving governance, and more.

What can Mercari do to help solve the issues faced by people around the world. With this question in mind, we will continue striving in our efforts to circulate the world’s resources and help society thrive.
