LSEG Bank Account Verification Solutions

Verifying bank accounts and ownership accurately is critical to preventing payment fraud and keeping money moving safely — whether those payments are domestic or cross-border. Many organisations still face gaps: account details change, urgent requests increase pressure, and fraud often appears late in the process when a payment is about to be sent. Traditional point-in-time checks are no longer enough for modern payment fraud prevention. Effective verification requires real-time insight into account validity, ownership, authorisation and recent changes — along with the context to understand why something looks risky, not just a binary yes or no.

Our Trusted Payments solutions help you provide assurance across the full payments lifecycle. In the United States, our LSEG Account Verification solution — formerly known as GIACT — deliver real-time insight into account existence, ownership and risk signals through a single API. We’re proud to be a preferred partner of Nacha. Internationally, our Global Account Verification provides real-time verification of global bank accounts and their owners in more than 45 countries, enabling confident cross-border payments.

With LSEG Account Verification solutions you can:

• Verify bank accounts and ownership for individuals and businesses across the US and global markets.
• Confirm whether an account is valid, active and authorised for the intended transaction, with insight into any recent changes that may indicate heightened risk.
• Maintain compliance with key regulatory requirements, including Nacha, PSD2, and FATF.
• Access contextual signals — including indicators linked to Account Takeover (ATO) and other patterns of suspicious activity — to help teams make informed decisions before money moves.
• Support customer and vendor workflows more efficiently, from onboarding through change events to payment execution, reducing friction for legitimate transactions while applying scrutiny only where needed.

LSEG Risk Intelligence helps organisations prevent fraud without slowing down business — ensuring payments reach the right place, at the right time, with confidence.
