The Largest B2B Fraud Consortium in the US Got A Facelift

A fraudster who burns one lender doesn’t retire. The same synthetic identity, the recycled EIN, the same officer name with a new phone number — they show up at the next institution a few weeks later, and the next one after that. Every financial institution has seen the pattern. Until now, most of them have fought it alone.

Most fraud committed against financial institutions is the work of repeat actors, and it comes in familiar shapes like first-party or synthetic identity fraud. The main challenge: by the time one institution writes off the loss, the same actor is already in someone else’s application queue.

Since 2024, the Baselayer Fraud Consortium has grown into the largest B2B fraud consortium in the United States – thousands of organizations, more than 1.2 million member-reported fraud records, over 10 million applications reviewed, and more than $1 billion in fraud losses prevented.

Today’s update wires that network directly into your workflow. There new ways consortium intelligence protects your organization, requiring zero integration work and surfacing any hits directly in your existing Baselayer search results.

This renewed version of the consortium also allows you to look up businesses with as little as a single identifier — an EIN, phone number, or email — and pair identifiers to catch synthetic identities that swap one field at a time.

The consortium works because of what it refuses to be: it’s not a predictive model and not a third-party list. Every matched record is a confirmed, peer-reported fraud case — first-party data contributed by member institutions from their own write-offs, enriched against Baselayer’s verified Business ID network for high-fidelity matching.

And it’s anonymous by design. Membership and submissions are anonymous; match results never name the contributing institution. Data is encrypted in transit and at rest, living in Baselayer’s existing US infrastructure.

The model is simple: give your fraud data, get protection. Members contribute their confirmed fraud cases on a monthly cadence, and every contribution makes the pool sharper for everyone. Hundreds of member submissions arrive every month, which means the business you screen tomorrow is checked against a network that’s smarter than it was today.

The consortium is available to Baselayer customers at no separate purchase, no new contract, no new API key.

1. Contribute — upload your fraud data in the Baselayer console.
2. Activate — your organization becomes an active consortium member.
3. Screen — every check you run is protected from that point on.
