LEI System

Does a Branch Need Its Own LEI?

Does a branch need its own LEI, or should it use the head office’s code? Opening a foreign branch does not automatically create a separate LEI requirement. This guide explains the difference between branches and subsidiaries, when reporting rules call for the head office’s LEI, and when a branch may need its own. Find out what to check with your bank, broker or supervisory authority before applying.

Branch LEI and head office LEI relationship

Opening a branch does not automatically mean you need another LEI

A company opens a branch abroad. The company already has an LEI (Legal Entity Identifier), but the branch has its own local registration number. Does it need a separate LEI too?

Not automatically. A foreign branch can qualify for its own LEI, but whether it needs one depends on the rules that apply to its activities and reporting. A local registration number alone does not create an LEI requirement.

The first thing to establish is whether the business is a branch or a subsidiary.

Branch vs subsidiary: what is the difference?

A branch forms part of the same legal entity as its head office. Registering it in another country does not turn it into a separate company.

A subsidiary is a separate legal entity. If its activities require an LEI, it needs its own. It cannot use its parent company’s LEI instead.

The ROC (Regulatory Oversight Committee) policy on international branches makes this distinction when setting out which branches qualify for an LEI.

When should a branch use the head office’s LEI?

Some reporting rules require the head office’s LEI, even where the branch could obtain its own.

For example, ESMA (European Securities and Markets Authority) explains that an investment firm based in the European Union must use its head office’s LEI when reporting transactions executed through a branch outside the Union.

This guidance concerns transaction reporting under Article 26 of MiFIR (Markets in Financial Instruments Regulation).

The branch forms part of the same legal entity as the investment firm.

Having a branch LEI does not mean it is the right code for every report. The applicable reporting rules determine which LEI to use.

When might a branch need a separate LEI?

A separate LEI may be needed where supervisory or reporting requirements identify the branch individually.

One example comes from the insurance sector. The EIOPA (European Insurance and Occupational Pensions Authority) guidelines on LEI use say that national supervisory authorities should require an LEI for branches established in the EEA (European Economic Area) whose insurance or reinsurance undertaking has its head office outside the EEA.

This is a specific supervisory case. It does not create a general requirement for every foreign branch to obtain an LEI.

A branch LEI allows authorities to identify operations in a particular country while keeping a clear link to the head office.

Which branches qualify for their own LEI?

Under the ROC policy on international branches, the conditions include:

  • The branch is located in a different country from its head office.

  • It is registered in a publicly accessible business, regulatory or tax register.

  • The head office has a current LEI.

  • The LEI reference data identifies it as a branch and records its connection to the head office.

If the company has several branches in the same foreign country, the policy provides for one LEI for the lead branch or branch network in that country. Each office does not receive its own code.

These conditions establish eligibility. They do not, by themselves, make an LEI mandatory.

What should you check before applying?

If a bank, broker or supervisory authority asks your branch for an LEI, clarify three things:

  1. Do they need the head office’s LEI or a separate LEI for the branch?

  2. Which transaction or report will the code be used for?

  3. If they require a branch LEI, which rule or service condition requires it?

A useful question to ask is: “Can we use our head office’s LEI for this purpose, or do you specifically require an LEI registered to the branch?”

Getting that answer before applying helps you avoid an unnecessary registration and makes sure you provide the correct code.
