Fraud Prevention


Detect fraud before it’s an issue.

Online fraud presents a material threat to individuals, corporations, and the broader economy, especially as mobile transactions are quickly becoming mainstream. According to LexisNexis, the cost of fraud for U.S. retail and ecommerce merchants, for instance, rose 15% in 2020 compared to 2019—every $1 of fraud cost these businesses $3.60.

The increase in mobile purchasing activity has led to growing fraud, escalating the need for new and improved fraud detection capabilities. Wireless carrier data has proven to be valuable in identifying potential fraud events.

Fraud Prevention by T-Mobile DevEdge is a collection of APIs that helps businesses detect fraud incidents through account and SIM verification, SIM change activity, routing verification, account change activity, and additional data points. Your organization will have access to a rich set of encrypted wireless data to identify suspicious activities and prevent fraud. And you are able to request individual data attributes or bundle the ones you need—see our pricing sheet under Resources for more details.
