ISO 20910:2019

Overview

ISO 20910:2019 specifies the terms, general requirements and data structure for coding radio frequency identification (RFID) tyre tags. Focused on passive UHF RFID tyre applications, the standard standardizes how a tyre’s Unique Item Identifier (UII) is encoded (using SGTIN‑96) and stored in tag memory to enable global tyre identification, traceability and interoperability across supply chains and IT systems.

Key topics and requirements

• Memory bank architecture: Defines use of the four ISO/IEC 18000‑63 memory banks - MB00 (reserved/passwords), MB01 (UII), MB10 (TID) and MB11 (user memory) - and their roles for tyre tagging.
• UII format: Requires a 96‑bit SGTIN‑96 (Serialized Global Trade Item Number) in MB01 as the tyre “birth record” to identify the tyre and link to databases.
• Security & locking:
  • MB01 must be programmed at commissioning and permalocked (made permanently read‑only).
  • Kill password must be set to 00000000h and permalocked; kill function disabled before leaving manufacturer facilities.
  • Access password can be left unlocked, locked, or permalocked depending on stakeholder requirements.
• Protocol compliance: Air interface and data organization must conform to ISO/IEC 18000‑63 (equivalent to GS1 EPC Gen2 V2).
• Data integrity: MB01 includes a 16‑bit CRC for verification and a PC (protocol control) word with specific bit requirements (e.g., bit 17 set to 0 per GS1 EPC rules).
• Optional user memory (MB11): Available for additional stakeholder data but used at the user’s responsibility.

Applications and users

ISO 20910:2019 is practical for:

• Tyre manufacturers - commissioning tags on the production line, embedding the UII, and ensuring permalock/security rules.
• Retreaders and tyre service providers - tracking casing histories, recording retread events and linking to databases.
• Distributors, dealers and fleets - inventory management, maintenance scheduling, warranty tracking and performance analysis.
• Supply chain and logistics teams - enabling interoperable RFID-based data capture and database lookups using standardized GS1 identifiers.

By aligning RFID tyre coding to GS1 and EPC standards, ISO 20910 supports cross-vendor interoperability, reduces IT integration effort, and enables scalable tyre traceability and asset management solutions.
