KYC failures are becoming a growing and costly issue across financial services and adjacent industries as fraud tactics continue to evolve. In 2024 alone, consumers in the US reported losses of more than $12.5bn to scams and fraud, representing a 25% increase year on year.
On a global scale, fraud is now estimated to consume close to 8% of business revenue, with TransUnion putting total losses at around $534bn over the past year, said AiPrise.
As fraudsters increasingly exploit weaknesses in identity verification through synthetic identities, deepfakes and automation, the cost of failed KYC processes continues to rise.
At its core, KYC failure occurs when a customer’s identity cannot be verified successfully during onboarding. This can be caused by poor-quality documentation, incorrect or inconsistent data, technical issues or overly rigid compliance rules that incorrectly flag genuine users as high risk. When verification fails, customers are often unable to proceed, leading to delays, abandonment and increased regulatory exposure for firms.
The consequences for businesses can be significant. Failed KYC checks can weaken risk scoring, allowing suspicious users to pass through inadequate controls. They also slow down onboarding, increasing customer drop-off rates as individuals are asked to resubmit documents or repeat checks. From a regulatory perspective, incomplete or unsuccessful KYC processes can create gaps in AML, KYB and customer due diligence obligations, exposing firms to fines and reputational damage. Poor user experience further compounds the problem, eroding trust and reducing conversion.
Many of the underlying causes of KYC failure are operational. The rise in sophisticated forged documents and synthetic identities means manual reviews and basic OCR tools are no longer sufficient. Fraudsters now use advanced editing tools and AI-generated templates that can bypass first-line checks. At the same time, reliance on manual workflows creates delays, inconsistencies and human error, particularly during periods of high onboarding volume.
Data quality is another persistent challenge. Blurry images, missing fields and mismatched information frequently stall verification processes and trigger unnecessary alerts. Without real-time validation and clear user guidance, these issues lead to repeated follow-ups and higher failure rates. High false positives further strain compliance teams, especially where static, rules-based systems generate large volumes of low-risk alerts that distract from genuine threats.
User experience also plays a critical role. Complex, fragmented onboarding journeys increase abandonment and error rates, particularly on mobile devices. Technical instability, including API failures and system downtime, can disrupt verification entirely, while limited data enrichment restricts a firm’s ability to build accurate risk profiles. A lack of integration with global sanctions, PEP and criminal databases compounds the issue for organisations operating across borders.
Effective record-keeping and auditability remain essential. Fragmented data storage, weak access controls and incomplete logs make it difficult to demonstrate compliance during audits. Finally, regulatory complexity adds another layer of risk. KYC requirements continue to evolve across jurisdictions, and businesses that fail to update internal policies and workflows in line with new rules face higher failure rates and enforcement action.
International regulations play a defining role in shaping KYC standards. In the US, the Bank Secrecy Act and the USA PATRIOT Act mandate strict customer identification and due diligence. The EU’s AML directives emphasise enhanced checks for high-risk customers and beneficial ownership transparency. In the UK, the Money Laundering Regulations 2017 require robust identity verification and ongoing risk assessment. Similar frameworks in Canada, India and China underline the global nature of compliance expectations and the consequences of falling short.
As fraud becomes more advanced and regulatory scrutiny intensifies, reducing KYC failure is no longer just a compliance exercise but a strategic priority. Firms that modernise their verification processes, improve data quality, automate workflows and align closely with global regulatory standards will be better positioned to protect customers, reduce friction and maintain trust in an increasingly complex risk environment.
