Full title and description

ISO/IEC 16023:2000 — Information technology — International symbology specification — MaxiCode. This international standard specifies the MaxiCode two-dimensional symbology: its symbol structure, module geometry, data encodation, symbol formats, dimensional/print quality requirements, error-correction rules and reference decoding algorithm for use primarily in transport and parcel-sortation applications.

Abstract

The standard defines the MaxiCode symbology (a fixed-size, square 2D code with a central bullseye/finder pattern and offset rows of hexagonal modules). It covers the character encodation, symbol formats and modes (including structured carrier messages used for postal and carrier data), the Reed–Solomon error correction approach, decoding reference behavior, dimensional and print/quality requirements, and user-selectable application parameters for reliable high-speed reading.

Scope

Specifies the complete symbology specification for MaxiCode: symbol geometry (hexagonal module grid and central finder), symbol sizes and quiet zone requirements, character encodation rules and symbol formats (modes for structured carrier messages and general-purpose data), error correction and recovery rules, reference decode algorithm and production/print quality parameters required to ensure robust scan/read performance in high-speed sortation and transport environments.

Key topics and requirements

• Symbol structure: fixed-size square symbol (~1 in × 1 in) with a central bullseye (finder) and offset rows of hexagonal modules; orientation and quiet-zone requirements.
• Encodation and modes: multiple modes including structured carrier message modes (modes 2 and 3) for postal/postal-like data and other modes for unformatted application data.
• Data capacity: up to approximately 93 alphanumeric characters (or higher numeric capacity per symbol), with support for structured append (linking symbols) to increase overall payload.
• Error correction: Reed–Solomon based error correction rules and recovery allowances to permit reliable decoding even with partial damage or distortion.
• Reference decoding algorithm: description of a reference decoding procedure to ensure interoperability between encoders/decoders.
• Dimensional and print quality requirements: symbol dimensions, module spacing/tolerances, and verifier/print-quality considerations to meet consistent read rates in production and high-speed sorting.
• Application parameters: user-selectable options and application notes for transport/carrier applications (postal code, country code, service class, application data fields).

Typical use and users

Primary users are parcel carriers, postal operators, logistics integrators, label/print suppliers, and software/hardware vendors implementing high-speed sortation and package-tracking systems. MaxiCode is commonly used on parcel labels where a compact, fast-to-locate code (with structured carrier data) aids automated sorting; implementers include carrier IT teams, barcode encoder/decoder vendors and printer manufacturers.

Related standards

Related and complementary standards include other 2D symbology specifications and 2D print-quality/verification standards such as ISO/IEC 16022 (Data Matrix), ISO/IEC 18004 (QR Code) and ISO/IEC 15415 (print-quality test specification for two-dimensional symbols). These are all managed under ISO/IEC JTC 1/SC 31 (automatic identification and data capture techniques).

FAQ

Q: What is this standard?

A: ISO/IEC 16023:2000 is the international standard that specifies the MaxiCode two-dimensional symbology — its symbol layout, encodation, error correction, decoding reference and production/quality requirements.

Q: What does it cover?

A: It covers the full technical definition of MaxiCode: symbol geometry (central bullseye and hexagonal module grid), encodation rules and symbol formats (including structured carrier message modes), error-correction rules, decoding reference, and dimensional/print-quality requirements needed for robust scanning.

Q: Who typically uses it?

A: Carriers and logistics operators (notably parcel sortation systems), postal operators, integrators, and barcode encoder/decoder and printer vendors. MaxiCode is optimized for high-speed package handling.

Q: Is it current or superseded?

A: The ISO record for ISO/IEC 16023:2000 shows the edition published in May 2000 and that the publication was subject to systematic review and was confirmed (reviewed) in later review cycles; the ISO catalog indicates this edition remains the published record for this standard. Users should consult the ISO catalog or their national standards body to verify the current status before procurement or compliance work.

Q: Is it part of a series?

A: It sits within the family of automatic identification and data capture symbology standards managed by ISO/IEC JTC 1/SC 31 and is conceptually related to other symbology specifications (for example ISO/IEC 16022 for Data Matrix and ISO/IEC 18004 for QR Code) and to print-quality/verification standards such as ISO/IEC 15415.

Q: What are the key keywords?

A: MaxiCode, 2D symbology, bullseye, hexagonal modules, Reed–Solomon error correction, structured carrier message, parcel sortation, ISO/IEC 16023.
