What Is a Business Identification Number (BIN)?

A Business Identification Number (BIN) is a core element of corporate identity. It is the unique code that links a legal entity to state registers, tax authorities, and supervisory bodies. When founders search “what is a business identification number?” they usually guess how this number is assigned, where it appears in documents, and how it affects day-to-day operations and cross-border activity. Understanding the structure and function of a business identification number (BIN) is therefore critical for any company that works with regulators, banks, and international partners.


Key points at a glance


A BIN is a unique identifier for a legal entity in state and tax registers.


  • It is required for registration, licensing, tax reporting, and opening a business bank account.

  • Different jurisdictions use different variations (i.e. Tax ID), but the function remains similar.

  • Tech, SaaS, FinTech, and Web3 projects rely on the BIN to pass KYC, AML, and contractual checks.


Legal advisers such as Icon.Partners ensure that your BIN is used consistently in all incorporation documents and meets cross-border compliance requirements.


Definition and Meaning


What is a Business Identification Number?


A Business Identification Number is a formal code assigned to a legal entity by a company register or tax authority. It appears on formation documents and later becomes the reference point for almost every official interaction. When a client asks, “What is a business ID?”, the answer is that it is the primary code that proves the existence of the company in public records and links it to its obligations. In most systems, one BIN belongs to one entity and remains in place for the entire lifetime of that entity.


BIN meaning in business and administration


The bin meaning in business goes beyond a simple registration number. It allows authorities, investors, and service providers to confirm that a company is valid, active, and properly recorded. Regulators use the bin identification number to track filings, sanctions lists, and compliance history. Banks and payment institutions rely on it when they review counterparties under AML and KYC rules. In practice, the phrase bin business in documentation often points to this identifier as the anchor for checks and reports.


Purpose of a BIN


Business registration and verification


A BIN code confirms that your company is registered in an official database. Such authorities as public registries, tender portals, licensing bodies, and even counterparties use it to verify that the company actually exists and its representative has the authority to sign contracts. During company incorporation in any jurisdiction, the BIN becomes a keystone of the documentation package, and legal teams often include it in documents such as resolutions, powers, and policies.


Tax reporting and compliance tracking


Tax authorities link filings and audits to the BIN code. This single identifier helps them connect corporate income tax returns, VAT reports, and other declarations to the correct entity company. Companies that plan international expansion or complex holding structures use the BIN as a stable reference point when coordinating tax advantages in a transparent and compliant manner, in line with OECD and local rules.


Legal identification in government databases


The BIN allows government portals to match online submissions to a specific company profile. It is widely used in digital signatures, e-government filing systems, and registers of licences or permits. Without a valid BIN, a business may not be able to file annual reports, register amendments, or obtain up-to-date extracts confirming good standing.


How to Find or Obtain Your BIN


Where to find the BIN number on official documents


Owners who are unsure where to find the bin number should review their incorporation certificate, extract from the commercial register, tax registration confirmation, or official online profile. In many jurisdictions, the BIN appears near the company name and legal form, often labelled as “registration number”, “business ID”, or another local definition.


Knowing what is the bin number on each document avoids confusion between it and internal reference numbers used by banks or service providers.


How to apply for a business identification number


In most systems, the BIN is issued automatically during the formation process. The application to create a legal entity leads to a review by the registry, and once the authority approves the filing, it assigns the BIN. Some countries require a separate registration with the tax authority before the number becomes fully active. Legal advisers coordinate filings, ensure that the information is consistent, and help the company obtain the BIN as part of a broader company incorporation project.


Differences by country (US EIN, UK CRN, EU VAT number, etc.)


Jurisdictions use different labels for similar identifiers. The United States uses EINs; the United Kingdom issues Company Registration Numbers (CRN); EU member states assign VAT IDs that can be checked through VAT/VIES systems; other countries adopt national business ID codes. All of them play a role similar to a BIN, but they may come from separate bodies and follow specific rules under local company and tax law.


What You Can Do with a BIN


Register for taxes and licenses


A BIN is usually mandatory when a business registers for corporate income tax, VAT, payroll taxes, or sectoral licences. Authorities use it to link each licence or registration back to the main entity. Understanding what can you do with a bin number helps founders logically structure their registrations and avoid duplicate profiles.


Open business bank accounts


Financial institutions and payment platforms routinely request the BIN before onboarding a client. They use it to confirm the company’s existence and to perform background checks.


When a technology business applies for a bank account with a digital bank or EMI, the combination of BIN details, corporate documents, and shareholder information forms the basis for risk assessment and KYC approval.


File annual reports or conduct cross-border transactions


Many jurisdictions require annual reports, financial statements, or confirmation statements under the BIN profile. Cross-border transactions, especially in regulated sectors, often involve BIN checks by counterparties, banks, and payment service providers. Clear use of the same number in contracts, invoices, and filings reduces errors and supports a consistent compliance record.


Why BIN Matters for Tech, SaaS, FinTech and Web3 Companies


Technology-driven businesses rely on remote onboarding and digital interaction. For a SaaS vendor or FinTech platform, the BIN is one of the key identifiers in KYC files maintained not only by partners but also by regulators and banks. Web3 projects that operate through corporate vehicles also require a clear BIN profile to meet AML expectations and to enter into structured agreements with service providers. When such companies expand to new markets, advisers like Icon.Partners coordinate local registrations, align BIN profiles across jurisdictions, and ensure that documents used in licensing, cloud contracts, or data-processing agreements all reference the correct identifier. This approach makes “what can you do with a bin number” a strategic question rather than a purely administrative one.


FAQ on Business Identification Numbers


What is the BIN number used for?


The BIN serves as the central identifier of a company in state, tax, and licensing registers. It is used when a business files returns, applies for permits, opens accounts, or signs major contracts.


Where can I find my business identification number?


You can usually find the BIN on the incorporation certificate, an extract from the commercial register, or tax registration letters. Many jurisdictions also allow searches in online databases using the company name.


Is BIN the same as a company registration number?


In several countries, the BIN and the registration number coincide, while in others, the company may receive a registration code and a separate tax or business ID. It is therefore important to review local practice and label each number correctly in documentation.
