LEI vs. DUNS vs. EIN: Understanding Corporate Identifiers

Legal Entity Identifiers (LEI), DUNS numbers, and IRS Employer Identification Numbers (EIN) serve distinct regulatory and compliance roles.

Comparing Corporate Identifiers

Compliance officers must understand the differences between financial, commercial, and tax-related corporate identifiers:

LEI: A global financial marker standardized under ISO 17442. Used primarily to track security trades and international banking relationships ^[1].
DUNS: A proprietary commercial credit marker issued by Dun & Bradstreet, used to evaluate business credit history and commercial risk ^[2].
EIN: A federal tax identification number issued by the IRS, used primarily for domestic tax reporting, payroll, and banking ^[3].

While U.S. government contracting systems transitioned from DUNS to GSA-owned Unique Entity IDs (UEI) in 2022, banks and international regulators still require LEI codes for trade reporting ^[2][1].

Frequently Asked Questions

Q: Can I use an EIN instead of an LEI?

No. An EIN is a domestic U.S. tax ID issued by the IRS, while an LEI is an international code required for global financial market trading.

Q: Who owns and administers the DUNS system?

The DUNS system is owned, managed, and licensed by Dun & Bradstreet, a private commercial corporation.

Q: What is the difference between a DUNS number and a TIN (Taxpayer Identification Number)?

A DUNS number is a proprietary commercial credit rating identifier issued by Dun & Bradstreet, while a TIN (such as an EIN) is a government-issued tax number used for federal tax compliance.
