KYC Documents: The Complete List and Requirements Guide (2026)

Whether someone is opening a bank account, joining a crypto exchange, or onboarding to a fintech app, the process starts with the same request: submit your KYC documents. These documents are how a business proves a customer is real, confirms who they are, and meets its anti-money laundering (AML) obligations.

This guide explains what KYC documents are, the full list of accepted identity and address documents, the exact information collected from them, how requirements differ by country and customer type, how digital verification works, and the red flags that get a document rejected. It also includes answers covering the questions customers and compliance teams ask most.

What are KYC documents?

KYC documents are the official identity and address records a business collects and verifies to confirm who a customer is during Know Your Customer (KYC) checks. They are the evidence behind Verificação de Identidade: a passport or national ID proves identity, and a utility bill or bank statement proves where the customer lives. KYC stands for Conheça seu cliente.

Businesses in regulated sectors, such as banks, payment firms, crypto platforms, and lenders, are legally required to collect KYC documents before giving a customer full access to their services. The goal is to Prevenir fraudes, money laundering, and financial crime by making sure each customer is genuine and correctly identified.

Types of KYC documents

KYC documents fall into three groups: proof of identity, proof of address, and, for business customers, entity documents. Most individual verifications need one identity document and, where the ID does not show a current address, one address document.

Documentos comprovativos de identidade

These confirm who the customer is and usually carry a photo and a document number. Commonly accepted prova de identidade documents include:

• Passaporte.
• Bilhete de identidade nacional.
• Driver’s licence.
• Government-issued photo ID card.
• Passport card, or in some cases a debit or credit card, where permitted.

Documentos comprovativos de morada

When the identity document does not show a current address, a separate proof of address is required. It must usually be issued within the last three months. Commonly accepted comprovante de endereço documents include:

• Utility bill (electricity, gas, water, or landline).
• Bank or credit card statement.
• Tenancy or rent agreement.
• Employer letter.
• Insurance agreement or policy statement.
• Tax bill or government-issued correspondence.

Business (KYB) documents

Verifying a company, known as Conheça o seu negócio (KYB), needs entity-level documents in addition to the identity documents of its owners and directors:

• Certificate of incorporation or registration.
• Business licence or trading licence.
• Proof of registered business address.
• Propriedade benéfica and shareholding records.

What information do KYC documents provide?

KYC documents are used to capture and confirm a defined set of data fields. Across most countries and jurisdictions, verification collects:

An AI-based document verification system also checks that the document itself is authentic: that it has not been forged, edited, or manipulated, and that the security features are intact.

Do KYC document requirements vary by country?

Yes. The documents required for KYC vary by country, regulator, industry, and the customer’s risk level. Some documents, such as a passport, are accepted almost everywhere, while others depend on local rules. For example, banks often ask for more documentation than a low-risk app signup, and high-risk customers may face due diligence aprimorada (EDD) with additional proof of source of funds. A business operating across borders needs a verification provider with broad document and country coverage to accept the right documents in each market.

How KYC document verification works (digital KYC)

KYC digital replaces paper forms and branch visits. Instead of filling in long forms and mailing copies, the customer uploads or captures a photo of a valid document, and the checks run automatically.

• Captura: the customer photographs or uploads the identity document, and a selfie where biometric matching is used.
• Extração de dados: reconhecimento óptico de caracteres (OCR) reads the document and extracts the data fields automatically.
• Autenticação: AI checks the document for tampering, forgery, and valid security features, and confirms it is not expired.
• Biometric match: the customer’s selfie is matched to the photo on the document, with liveness detection to stop spoofing.
• Decisão: a verification result is returned in seconds, cutting a process that once took hours or days.

Why KYC documents get rejected

Understanding the common rejection reasons helps customers pass on the first attempt and helps businesses spot fraud. A KYC document is typically rejected when:

• It is expired or close to expiry.
• The image is blurry, cropped, or has glare that hides details.
• The address proof is older than three months.
• The name or details do not match across documents.
• The document shows signs of editing, forgery, or manipulation.
• The selfie does not match the photo on the ID, or fails a verificação de vivacidade.
