Your customers changed. Did your data?
Customer data that was accurate at onboarding doesn't stay that way. Phone numbers change. Addresses change. Risk changes. Yet you're asking that data to do more than ever — power AI, reach customers, satisfy auditors.
Re-verify customer data in a single batch pass to see how much of it still holds up.
The back book you can't see is the risk you can't manage.
Businesses invest heavily in verifying customers at onboarding. But months or years later, the data behind those relationships may tell a different story.
This is especially important when:
- Dormant customers interacting with high risk transactions (wire, P2P, password reset)
- Authenticating without friction
- Investigating fraud
- Preventing account takeovers
Prove helps you revisit your existing customer base in a single batch process, helping you understand what's accurate, what's changed, and where additional attention may be warranted.
From millions of records to a clearer picture. Just 4 steps.
Transfer the customer records you want to re-verify through an encrypted batch process designed to protect sensitive customer data from submission through processing.
Re-verifies each record against current evidence rather than re-scoring the data you already have, confirming PII validity and phone ownership, then layering in current reputation and behavioral-risk signals.

Most portfolio verification ends at the output file, which means the same decay starts over the moment the project closes. Prove is built to keep going.The identities you verify can move into Prove Identity Manager for ongoing monitoring, so you're notified as soon as something material changes.

Many reasons to re-verify.
Give AI and agentic systems verified customer data instead of outdated, incomplete, or conflicting information. Better inputs create a stronger foundation for personalization, decisioning, automation, and agentic workflows.
Verify critical contact information so you're not wasting outreach on phone numbers, emails, or addresses that no longer connect. Better data means fewer failed interactions and a better customer experience.
Re-verify PII and phone ownership while evaluating current risk signals. Strengthen identity resolution, identify records that warrant closer review, and give fraud and compliance teams greater confidence in the customer data they're relying on.

Instead of ending with a static output file, the re-verified identities moved into ongoing monitoring so the bank is notified the moment something material changes again.
Questions we get asked first.
Yes. Customer Portfolio Verification can be used as a one-time portfolio re-verification or as the starting point for ongoing identity monitoring. Identities verified through the process can move into Prove Identity Manager for monitoring over time, helping organizations identify material identity changes after the initial portfolio review.
Prove provides a record-level output showing verified identity and contact data, what has changed, and risk signals for accounts that may warrant review. Teams can use the results to prioritize remediation and make more informed identity and risk decisions.
Prove re-verifies existing customer records against current evidence, including PII validity and phone ownership, and layers in current reputation and behavioral risk signals. The result helps businesses understand which customer records still verify, what has changed, and where additional attention may be warranted.
Customer information does not remain static after onboarding. Phone numbers, addresses, emails, devices, and other identity signals can change over time. Re-verifying an existing customer portfolio gives banks a more current view of their customer base and can support fraud prevention, KYC and compliance workflows, customer outreach, M&A integration, and AI initiatives.
Customer portfolio verification is the process of re-verifying identity and contact data for customers a business has already onboarded. Sometimes called a portfolio scrub, it helps organizations determine what customer information still verifies, what has changed, and which records may warrant additional review.
Trusted by 2,000+ leading companies to reduce fraud and improve consumer experiences, Prove is the world’s most accurate identity verification and authentication platform.
