LEI

published · September 10, 2026

A Legal Entity Identifier is a 20-character code identifying a legal entity that takes part in financial transactions, defined by ISO 17442.

A Legal Entity Identifier is a 20-character code identifying a legal entity that takes part in financial transactions, defined by ISO 17442. Eighteen characters identify the entity and the last two are a check digit.

What Spaw answers

identifier_type is lei, and the answer carries the legal name, the status in the register's own wording, the country, the jurisdiction and the incorporation date. Three fields belong to the LEI alone: checksum_valid, registration_status and next_renewal_at.

That last pair matters because a LEI is a subscription. It lapses if nobody renews it while the company behind it carries on trading, so registration_status is a fact about the identifier and never about whether the business is alive. The flag lei_registration_not_current names it when it happens.

What it is not

It is not official reference data and Spaw is not affiliated with the organisation that runs the LEI system. The answer here is a derived verdict read from a daily copy of the public file, held on this server so that no third party sits in the request path, and every response names the date of the copy it read.

There is no registered address in the answer, deliberately: an identifier does not say whether a company or a sole trader stands behind it, and a registered address is very often somebody's home.

More glossary

  • Area-code overlay

    An area-code overlay is a new area code added over the same area as an existing one, instead of splitting it, so neighbours can hold different codes and local calls need ten digits.

  • Calling window

    A calling window is the span of local hours a sender contacts people in. Spaw answers in_call_window from the number's time zones: clock arithmetic, not compliance advice.

  • Fictional number

    A fictional number sits in a range kept out of service for films, TV and other fiction: 555-0100 to 555-0199 in North America, and ranges Ofcom, ARCEP, ACMA and ComReg reserve elsewhere.

  • International (exit) prefix

    An international prefix is what is dialled to leave a country before the calling code: 00 in most of the world, 011 in North America. Spaw reads it and suggests a fix in did_you_mean.

  • International network number

    An international network number sits under a calling code the ITU gives a global service rather than a country, such as +870, +881, +882 or +883, so its country is null.

  • Live carrier check (HLR lookup)

    A live carrier check asks the mobile networks, at the moment of the lookup, whether a number is in service, which network serves it and whether it is roaming. On Spaw it is not enabled.

  • Number pooling (thousands-blocks)

    Number pooling splits a North American central office code into ten blocks of a thousand numbers, each assigned to a carrier separately, so one code can hold several carriers' numbers.

  • Number portability

    Number portability lets a subscriber keep a phone number when changing carrier. The number's block stays listed under the carrier it was issued to, so block data names the original holder.
