UTI Generator & Validator

Generate ISO 23897 compliant Unique Transaction Identifiers or validate existing UTIs with LEI checksum verification and GLEIF entity lookup. Supports batch operations up to 50,000 UTIs.

Generating Entity LEI (ISO 17442)

Enter the 20-character LEI of the generating entity

0 / 20 characters

Trade Identification Details

Platform

Generating Party

Receiving Party

Internal Trade ID

Accepts special characters including pipes

Version

Hash input:

How it works

1 Enter the 20-character generating entity LEI

2 Fill in trade details (platform, parties, internal ID, version)

3 The pipe-separated input is hashed with MD5

4 UTI = LEI prefix + MD5 hash (52 characters, ISO 23897)

Hash Input Format

PLATFORM|GENERATING PARTY|RECEIVING PARTY|INTERNAL ID|VERSION

Example:

BBG|2138002RMY29Z38WWN81|549300O9PUG5E512LD66|MCDOWIQ39292/1|1

The pipe-separated string includes Platform, Generating Party, Receiving Party, Internal ID (may contain special characters), and Version (integer). The full string is MD5-hashed and uppercased to produce the 32-character unique part.

UTI Format (ISO 23897)

• Maximum 52 characters total
• First 20 chars = LEI prefix (ISO 17442)
• Last 32 chars = MD5 hash of trade details
• Allowed: uppercase A–F, digits 0–9

Generating Entity LEI (ISO 17442)

All UTIs in this batch will use this LEI as prefix

For manual paste, format: Platform|GenParty|RecvParty|InternalID|Version. The Internal ID may contain pipes — version is always the last segment.

Supports up to 50,000 trades per batch. Special characters in Internal ID are fully supported.

Paste UTI Codes

Enter one UTI per line, or separate with commas. Maximum 50,000 codes.

Ctrl + Enter to validate

How it works

1 Paste up to 50,000 UTIs (one per line)

2 Format, length and character rules are checked

3 LEI prefix checksum is validated (MOD 97-10)

4 Valid LEIs are looked up via GLEIF for entity name

5 Download the full validation report as CSV

Validation Checks

• Total length: 21–52 characters
• Allowed characters: A–Z uppercase, 0–9
• LEI prefix: ISO 17442 checksum (MOD 97-10)
• GLEIF lookup for generating entity name

UTIs follow ISO 23897, required by EMIR, MiFIR, CFTC, and other global regulatory frameworks.
