LEI Proof

About

Look up any LEI (Legal Entity Identifier) and monitor your watchlist against the official GLEIF API — the global LEI system operated by the Global Legal Entity Identifier Foundation.

A lapsed LEI blocks regulatory reporting (EMIR, MiFID II) and slows down onboarding with banks and counterparties. LEI Proof gives you the registration status in one click and warns you before renewals expire.

FEATURES
- Instant LEI lookup via the official GLEIF public API (no account, no API key)
- Search by company name when you don't have the code
- Entity status, registration status, jurisdiction, next renewal date
- Local watchlist: monitor your LEIs and spot lapsed or expiring codes at a glance
- Renewal alerts shown right in the popup - never miss a renewal window

PRIVACY - HONEST BY DESIGN
The LEI codes and names you search are sent only to api.gleif.org (the official GLEIF service). Your watchlist and settings never leave your browser. No backend, no analytics, no tracking, no account.

HONEST LIMITS
