How to Verify Someone's Identity Online — The Complete Guide

Online identity verification has become essential for businesses across almost every industry. Whether you are onboarding a new client, processing a high-value transaction or meeting regulatory requirements, knowing that the person you are dealing with is who they claim to be has never been more important — or more straightforward.

This guide explains everything businesses need to know about verifying identity online: what it involves, how it works, what documents are used, what it costs and when you are legally required to do it.

What is Online Identity Verification?

Online identity verification is the process of confirming that a person is who they claim to be using digital methods — without needing to meet them in person. A complete identity verification typically involves three steps:

1. Data verification — the person's name, date of birth and address are checked against government databases
2. Document verification — the person scans a government-issued ID document, which is authenticated against a database of known genuine documents
3. Biometric verification — the person takes a live selfie, which is matched against the photo on their ID document using facial recognition technology

Together, these three checks give a business high confidence that the person is genuine, that their identity document is real and that the document actually belongs to them — not someone else using a stolen or borrowed ID.

Why Businesses Need to Verify Identity Online

There are two main reasons businesses verify identity: compliance and fraud prevention.

Compliance is driven by anti-money laundering (AML) regulations. In Australia, the AML/CTF Act requires thousands of businesses — including accountants, lawyers, real estate agents, financial planners and others — to verify client identities before providing certain services. Similar laws apply in the UK, EU, US and most developed economies. Failure to verify can result in significant penalties.

Fraud prevention matters regardless of regulatory requirements. Identity fraud costs businesses and consumers billions of dollars annually. A fraudster using someone else's identity to open an account, secure a loan or enter a contract can cause serious financial and reputational damage. Online identity verification creates a documented, verified record that the right person was confirmed before any transaction or service began.

Methods of Online Identity Verification

Electronic ID Checks (DVS/Database Matching)

Electronic ID checks match a person's details — name, date of birth, ID number — against government databases in real time. In Australia, this is done through the Document Verification Service (DVS), which connects to Medicare, driver licence, passport, visa and other government records. This is the fastest and least friction-heavy method for Australian clients.

Document Capture and Authentication

The person photographs or scans their ID document using their phone camera. Software checks the document against a database of over 8,500 government-issued ID templates from 195 countries, detecting tampering, forgeries and inconsistencies that are invisible to the human eye.

Biometric Face Matching and Liveness Detection

The person takes a selfie or short video. AI software maps their facial features and compares them against the photo on their ID document. Liveness detection confirms the person is physically present and not using a photo, deepfake or screen display to fool the camera.

PEP and Sanctions Screening

As part of a complete KYC process, the person's name is screened against lists of politically exposed persons (PEPs) and sanctioned individuals. In Australia, this includes the DFAT Consolidated List. Matches are flagged immediately for review.

How Long Does Online Identity Verification Take?

With a modern platform like VerifyID Online, the entire process takes an average of two to three minutes for the client to complete. The business receives the result instantly. Compare this to traditional in-person ID checks, which typically require scheduling, travel and manual document handling — a process that can take days.

What Does Online Identity Verification Cost?

The cost of online identity verification varies significantly by provider and method. As a guide:

• Electronic-only checks for Australian clients: from $4–$6 per check
• Full verification including document capture and biometrics: from $6–$15 per check
• Manual in-person ID checks: $25–$200 in staff time and overheads per check

VerifyID Online starts from $6 per verification on the Professional plan — significantly less than any manual alternative, and with a complete audit trail and 7-year record storage included.

When Are Businesses Required to Verify Identity?

In Australia, identity verification is mandatory for businesses providing designated services under the AML/CTF Act. Following the Tranche 2 reforms effective 1 July 2026, this now includes accountants, lawyers, real estate agents, conveyancers, financial planners, mortgage brokers and precious metals dealers — approximately 90,000 additional businesses.

Even where not legally required, verifying identity is considered best practice for any business handling significant transactions, onboarding new clients remotely or operating in sectors with elevated fraud risk.
