PayPal Unveils Ad Identifier Linked to 400 Million Accounts
PayPal has launched PayPal Ads ID, a deterministic advertising identifier linked to over 400 million user accounts. As a result, the company positions itself as a direct competitor to traditional cookie- and device-based systems. Meanwhile, the identifier also integrates data from Venmo accounts to strengthen its reach.
Unlike older tracking methods, this system relies on authenticated user data. Therefore, it avoids inconsistencies tied to cookies, device fingerprints, or IP tracking. Instead, it verifies identity at the moment of purchase, which ensures stability across devices and sessions. In total, the identifier draws from more than 25 billion transactions, giving it a strong commerce-based foundation.
“Identity is fundamental to all aspects of advertising. For far too long, that foundation has relied on guesswork,” said Mark Grether, senior vice president and general manager of PayPal Ads. “With PayPal Ads ID, when your identity framework is established on confirmed commerce relationships, you are no longer making assumptions about who someone is; you are engaging with them confidently.”
At the same time, industry data shows only 21% of brands feel confident identifying audiences across platforms. Consequently, PayPal aims to solve issues such as low match rates, fragmented tracking, and weak links between ads and purchases.
Partnerships and Privacy Safeguards
To expand adoption, PayPal has partnered with several ad technology platforms. These include Magnite, PubMatic, Rokt, and Taboola. As a result, the identifier will operate across open web, connected TV, and native advertising channels.
Moreover, the company offers the identifier free to partners, which encourages wider adoption. Instead of charging per use, PayPal expects increased retail media spending to drive growth. However, it also emphasizes strong privacy protections. Each identifier undergoes encryption, aggregation, and de-identification to protect user data. In addition, users can opt out and manage their participation at any time.
Expanding Role in Digital Advertising
This launch builds on PayPal’s broader advertising strategy, which has developed steadily since 2024. Notably, the company leverages a transaction network spanning about 30 million merchants worldwide. Therefore, it gains a cross-merchant view of consumer behavior that many retail media networks cannot match.
Furthermore, PayPal Ads has already attracted major brands such as Mercedes-Benz, Uber, DoorDash, and Walmart. At the same time, it has expanded its display and video advertising services into the United Kingdom and Germany.
Looking ahead, industry forecasts suggest strong growth in retail media. For instance, estimates project off-site retail media spending will reach $17 billion in 2026 and rise to $25.6 billion by 2029. As a result, PayPal’s new identifier could play a key role in shaping the future of digital advertising.
