ISO 9019:1995

Overview

ISO 9019:1995 - Securities: Numbering of certificates - establishes international rules for the numbering of security certificates. Applicable to all types of securities (bearer or registered), regardless of issuer or country, this second edition (replacing ISO 9019:1987) specifies how certificate numbers and series designations must be formed, displayed and managed to ensure unique, legible and machine-friendly identification.

Key topics and requirements

• Unique certificate number: Each physical certificate must carry one unique certificate number identifying that specific document.
• Permitted characters: Arabic digits (0–9) and Roman capital letters (A–Z) may be used; avoid ambiguous letters (for example I, O, Q) to prevent misinterpretation with digits.
• Legibility: Letters and digits must be clearly identifiable; certificate numbers on coupon sheets or attachments must be shown in full.
• Length limits: Maximum of 8 characters for bearer certificates (exception when circulation is expected to exceed 90 million), and 12 characters for registered certificates. These are maxima, not minima.
• No separators: Certificate numbers shall not contain blank characters or separators (with limited exceptions noted in the standard).
• Series designation rules: If used, a series designation (up to 4 characters) precedes the certificate number and must be separated (e.g., by a full stop or a blank). Series designations must differentiate portions of the same issue; they must not be placed near optical-scan areas if they do not serve as part of the number.
• Non-duplication: Numbers must not be repeated within the same series or issue.

Applications

ISO 9019:1995 is used to:

• Design and print compliant security certificates and coupon sheets.
• Define numbering rules for registrars, transfer agents and security printers.
• Enable consistent indexing and tracking of certificate documents across markets and custodians.
• Reduce errors in manual reading and automated processing (including optical scanning/OCR-future standards may further specify OCR separation).
• Support interoperability for cross-border securities handling and settlement systems.

Who uses this standard

• Issuers and corporate registrars
• Transfer agents and depositories
• Custodians and clearing organizations
• Security printers and certificate designers
• Banks and financial institutions involved in securities processing
• Software vendors building securities issuance and track-and-trace systems
