In the course of the investigation into Coupang's large-scale personal information leak that occurred in Nov. last year, it was confirmed that the personal information of about 165,000 accounts was additionally leaked.
On the 5th, Coupang notified customers subject to the additional personal information leak by text message. Coupang said, "We immediately blocked the abnormal access route related to the personal information leak that occurred in Nov. 2025 and completed the response," and added, "In the same personal information leak incident that occurred in Nov., an additional leak involving about 165,000 accounts was confirmed."
Coupang notified customers of the additional leak in accordance with the Personal Information Protection Commission's recommendation. The leaked information is the address book information entered by customers (name, phone number, address). Coupang said that payment and login-related information, as well as email, order history, and communal entrance codes, were not leaked. Coupang plans to provide compensation in the form of purchase vouchers worth 50,000 won per person to the customers affected by the additional leak. In the notice, Coupang emphasized that links from unclear sources should never be clicked and related text messages should be deleted or reported.
It is still unclear whether the number of people affected by the personal information leak will expand from the existing 33.7 million to 33.865 million. According to the industry, the government and Coupang are said to be identifying the number of invalid accounts among the previously announced 33.7 million. Invalid accounts are accounts that have no personal information such as name, phone number, or address at all, or for which member information cannot be identified.
However, the credibility of Coupang's self-investigation results, which it emphasized, has been damaged. On Dec. 25 last year, announcing the results of its internal investigation, Coupang said, "(The information leaker) accessed basic customer information for about 33 million customer accounts but saved customer information for only about 3,000 accounts among them."
