What is KYC in Banking?

Updated: July 15, 2026 by Stefani Wendel 5 min read March 21, 2024

At A Glance

Know Your Customer (KYC) procedures are a requirement for banks and other financial institutions to collect and verify the identity of their customers. When a bank verifies the identity of another organization or its owners, the process may be called Know Your Business (KYB) instead. 

As part of banks’ anti-money laundering (AML) programs, KYC in banking can help stop corruption, money laundering and terrorist financing. Creating and maintaining KYC programs is also important for regulatory compliance, reputation management and fraud prevention.

The three components of KYC in banking programs

Banks can largely determine how to set up their KYC and AML programs within the applicable regulatory guidelines. In the United States, KYC needs to happen when banks initially onboard a new customer. But it’s not a one-and-done event—ongoing customer and transaction monitoring is also important.

1. Customer Identification Program (CIP)

Creating a robust Customer Identification Program (CIP) is an essential part of KYC. At a minimum, a bank’s CIP requires it to collect the following information from new customers:

  • Name
  • Date of birth
  • Address
  • Identification number, such as a Social Security number (SSN) or Employer Identification Number (EIN)

Banks’ CIPs also have to use risk-based procedures to verify customers’ identities and form a reasonable belief that they know the customer’s true identity.1 This might involve comparing the information from the application to the customer’s government-issued ID, other identifying documents and authoritative data sources, such as credit bureau databases.

Additionally, the bank’s CIP will govern how the bank:

  • Retains the customer’s identifying information
  • Compares customer to government lists
  • Provides customers with adequate notices

Banks can create CIPs that meet all the requirements in various ways, and many use third-party solutions to quickly collect data, detect forged or falsified documents and verify the provided information.

2. Customer due diligence (CDD)

CIP and CDD overlap, but the CIP primarily verifies a customer’s identity while customer due diligence (CDD) helps banks understand the risk that each customer poses.

To do this, banks try to understand what various types of customers do, what those customers’ normal banking activity looks like, and in contrast, what could be unusual or suspicious activity.

Financial institutions can use risk ratings and scores to evaluate customers and then use simplified, standard or enhanced due diligence (EDD) processes based on the results. For example, customers who might pose a greater risk of laundering money or financing terrorism may need to undergo additional screenings and clarify the source of their funds.

3. Ongoing monitoring

Ongoing or continuous monitoring of customers’ identities and transactions is also important for staying compliant with AML regulations and stopping fraud.

The monitoring can help banks spot a significant change in the identity of the customer, beneficial owner or account, which may require a new KYC check. Unusual transactions can also be a sign of money laundering or fraud, and they may require the bank to file a suspicious activity report (SAR).

Why is KYC important in banking?

Understanding and implementing KYC in banking processes can be important for several reasons:

  • Regulatory compliance: Although the specific laws and rules can vary by country or region, many banks are required to have AML procedures, including KYC. The fines for violating AML regulations can be in the hundreds of millions— a few banks have been fined over $1 billion for lax AML enforcement and sanctions breaching.
  • Reputation management: In some cases, enforcement actions and fines were headline news. Banks that don’t have robust KYC procedures in place risk losing their customers’ trust and respect.
  • Fraud prevention: In addition to the regulatory requirements, KYC policies and systems can also work alongside fraud management solutions for banks. Identity verification at onboarding can help banks identify synthetic identities attempting to open money mule accounts or take out loans. Ongoing monitoring can also be important for identifying long-term fraud schemes and large fraud rings.

KYC in a digital-first world

Modernizing KYC in banking is a key part of financial institutions’ digital transformationefforts. Part of that journey is updating the systems and tools in place to meet the expectations of customers and regulators.

Experian’s 2025 U.S. Identity and Fraud Report shows four in 10 consumers considered abandoning a new account setup midway through the process – rising to 50% among high-income earners – highlighting growing expectations for seamless digital experiences. The survey wasn’t specific to financial services, but friction could be a problem for banks wanting to attract new account holders.

Just as access to additional data sources and machine learning help automate underwriting, financial institutions can use technological advances to add an appropriate amount of friction based on various risk signals.

Some of these can be run in the background, such as an electronic Consent Based Social Security Number Verification (eCBSV) check to verify the customer’s name, SSN and date of birth match the Social Security Administration’s records. Others may require more customer involvement, such as taking a selfie that’s then compared to the image on their photo ID — Experian CrossCore® Doc Capture enables this type of verification.

Financial Institutions Are Rethinking Customer Acqusition

Customer acquisition strategies are constantly evolving toward more precise targeting. From a marketing lens, you can track every step, optimize communication channels and still miss the person most likely to convert. Attribution can tell us which channels work and automation can make marketing spend more efficient. But both assume we know who is actually on the other end. Financial institutions are learning that finding audiences and targeting them is no longer the biggest challenge. As acquisition optimization marketing becomes more sophisticated, teams can measure and act on more signals than before. What they can't always know is whether the person on the receiving end is real. Customer acquisition has evolved into an identity problem. The challenge is not that every questionable signal represents malicious activity. It's that acquisition systems must make increasingly intelligent decisions with an imperfect understanding of who they're actually engaging. When identities are fragmented, duplicated, temporary or synthetic, optimization becomes a question of trust as much as targeting. When your signals don't reliably identify customers The customer journey often includes searching, filling out a form, creating an account, requesting a quote and subscribing. All of these signals work well when identity is relatively stable.  However, financial institutions are finding that these signals are becoming less reliable. A single person can operate across multiple personas, devices, browsers, aliases, accounts and intermediaries while several apparent “people” may actually represent one underlying actor. Financial instituions are finding: Fragmented customer signals Difficulty distinguishing an old account from a new one Different digital pathways associated with the same individual Signals that are generated by automation Real customers getting flagged because signals are too thin to evaluate confidently Legacy signals continue to be challenged Marketing has historically treated intent as a valuable signal because intent was relatively difficult to produce. A search required human intent. A form required someone to fill it out. An inquiry implied a meaningful amount of human effort. Financial institutions are already combating AI-enabled fraud, and now marketing teams are starting to face it on a massive scale. AI can mimic human behavior by researching products, comparing prices, filling out forms, creating accounts and signing up for services. A valid email address is no longer enough. Marketers need to know: How long has it existed? How recently has it been active? Does its activity appear consistent or suddenly anomalous? Has it gone dormant and returned? Is it associated with patterns that suggest stability or unusual behavior? How to build on your strongest signal Email remains one of the most persistent identifiers in digital commerce, following people across devices, platforms, transactions, subscriptions, accounts and years of activity. For over two decades, this has shaped how AtData thinks about identity. Now, as part of Experian, it’s shaping how an entire platform and team approach identity. A marketer doesn’t need every prospect to have existed online for twenty years. But understanding whether a newly acquired prospect has meaningful identity context can dramatically improve the quality of the decision being made around it. Better identity intelligence can help organizations reduce unnecessary friction by improving their ability to recognize legitimate customers. With a strong identity foundation, marketing teams can better address: Which audiences are more likely to convert? Which leads are high quality? Which channels are driving incremental growth? What do the best prospects look like? The value isn't simply having an email address. It's understanding the history and behavioral context associated with it. That context can provide a stronger digital identity signal, helping marketers understand how long they have been active, whether its behavior is consistent with that of a real person and whether current activity aligns with past patterns. It continues to be one of the most persistent identifiers in digital commerce. An infrastructure built for what's coming The acquisition of AtData by Experian reflects a fundamental shift in how identity infrastructure needs to work. Experian's scale and decisioning capabilities, combined with AtData's real-time email intelligence, create a strong platform.

As Electric Vehicle Adoption Eases, Dealers Can Find New Opportunities To Reach Consumers

After years of rapid growth, new electric vehicle (EV) registrations have moderated, and the EV market has entered a new chapter. But slower growth shouldn’t be mistaken for disappearing demand, with data suggesting the reality is much more nuanced. According to Experian Automotive’s Automotive Consumer Trends Report: Q2 2026, battery EVs accounted for 8.21% of new retail registrations in the last 12 months, down from 9.23% a year earlier. However, consumers aren’t simply walking away from electrification. In fact, more than one million new EVs were registered during the past 12 months and the used EV market recorded more than 540,000 registrations over the same period. The opportunity may be less about waiting for the EV market to grow and more about understanding where EV demand is present, who is driving them, and how to reach those consumers more effectively. Who is likely to purchase an EV and what vehicle types are they interested in? Understanding who’s in the market for an EV can allow dealers to position themselves around consumers’ needs as they choose a vehicle that fits their everyday lifestyle. In the second quarter of 2026, Millennials and Gen X accounted for 67.83% of new EV registrations, nearly 10 percentage points above their combined share of all new, retail registrations. Millennials were also the largest generational audience across both new and used EV market share, coming in at 35.76% and 38.42%, respectively. It’s important to consider that the EV shopper isn’t necessarily looking for an unfamiliar or new type of vehicle. In many cases, they’re seemingly looking for an electric version of the practical vehicle they already know. For instance, SUVs accounted for 77.47% of new EV registrations in Q2 2026, which was similar to SUVs’ 63.49% share of all new retail registrations. For these shoppers, creating messaging around value, practicality, and available choices may resonate differently than premium technology messaging aimed at some new-EV prospects. The more precisely dealers can identify those audiences, the less they need to depend on broad EV market momentum to generate demand.
