What is customer verification?

Customer verification is confirming a user's identity to ensure they are who they claim to be. This is often done through document verification, two-factor authentication (2FA), or biometric checks. It helps businesses reduce fraud, comply with regulations like Know Your Customer (KYC), and secure transactions by validating users before granting access to services or sensitive data.

What are customer verification services?

Customer verification services authenticate user identities to enhance security and prevent fraud. Organizations can safeguard sensitive information and foster a secure user environment by implementing effective customer verification solutions. Here are some examples of customer verification services.

Multi-channel verification

This service allows businesses to verify customer identities across various mobile, web, and in-person interactions.

Global coverage

Customer verification services offer the capability to authenticate users from different countries, ensuring compliance with international standards.

Fraud prevention

These services help detect and mitigate fraudulent activities by validating customer identities before granting access to services.

Compliance support

This service assists businesses in meeting regulatory requirements, such as Know Your Customer and Anti-Money Laundering (AML) laws.

Enhanced security

Customer verification services improve security by implementing robust measures to protect sensitive data and ensure only legitimate users access systems.

What is a customer verification API, and how does it work?

Customer account verification APIs grow your company's ability to protect itself and your customers and employees from various types of fraud and other illicit behavior. They can also give end users a real sense of security as they interface with your apps and systems, which can build greater trust in your business.

These days, a password is only a first line of defense, and consumers need extra layers of verification to protect them. In this case, the API-based architecture does the heavy lifting. Providing true viable verification capabilities across a global or domestic communications stack requires a lot of moving parts on the backend — for example, sender ID management, password generation, intelligent failover, and active fraud monitoring are just four highly complex parts that must work in lockstep for the entire system to function as a whole.

The identity check API virtualizes the deep telecom and security knowledge required, allowing companies to integrate highly advanced functionalities into current and planned apps and systems in a fraction of the time it would cost to develop from the ground up.

Key features of a verify customer API

• Document verification

• Biometric authentication

• Data validation and cross-referencing

• Real-time verification

• Compliance and regulatory checks

• Customization and integration

Two-factor authentication is a big part of the average verification API offering, but it's far from the only thing it can do. Bringing 2FA capability onboard and attaching it to your current phone number — or all-new numbers, on any kind of phone line, anywhere in the world, without the need for additional hardware or apps — is a substantial benefit in and of itself.

Added verification via a Know Your Customer API isn't only a benefit on the user's side — for the company deploying the API, advanced spam and botnet detection/prevention capabilities mean scammers and fraudsters have less room to build bulk "zombie" accounts and engage in illicit activities, like toll fraud, either of which can become costly fast if not addressed with the right cadence, especially for companies with a global presence.

Following that, global compliance with SMS and messaging rules is a big part of a competent verify identity API. Figuring out the complexities of sender IDs and their global compliance is another hurdle that only grows with the number of countries in which the business operates. With identity verification APIs, all the heavy lifting is already done, granting companies that deploy the software faster time-to-market with less chance of costly compliance snags that can set projects and entire infrastructures back.

By keeping customers safe and building an ongoing sense of trust without overburdening them with extra steps, your business doesn't just make sure more of the conversions it undergoes are legitimate but also ensures more security- and privacy-conscious customers are likely to convert. And since the most viable solutions only bill on successful conversions, you get a solution that scales exactly as your company does, with no need to overpay for services that aren't used.

Does a customer verification API only work via SMS?

Vonage utilizes Adaptive Routing technology to ensure messages get to where they're supposed to go and make extremely low latency the standard. That means your SMS-based users get their verification message even during peak congestion, ensuring you won't lose conversions or customer trust due to frustrating technical snags.

A customer identity verification API can also be configured to utilize text-to-speech voice during customer communication, with the OTP coming via a phone call to any type of phone line. This extends the verification capability to differently-abled users and gives a stronger sense of security to users who may wish to keep their OTP private from phone memory.

This service can also be configured to work via any email address, and it can even verify via WhatsApp using a standard OTP delivered via a WhatsApp message. Silent Authentication, an automatic, no-input option gaining a lot of traction in enterprise communications stacks, is another great option for companies seeking to add a more secure  layer of verification without complicating the user experience.
