The GS1 DataMatrix typically includes only the core identifiers:
- GTIN (AI 01)
- Batch / Lot Number (AI 10)
- Expiry Date (AI 17)
- Serial Number (AI 21)
This model represents the baseline GS1 implementation adopted by most authorities in the region.
Despite the global GS1 framework, some countries introduce local exceptions within serialization and the embedded GS1 DataMatrix.
These exceptions are driven by regulatory control models, anti-counterfeiting strategies, or legacy identification systems.
CIS Countries: Crypto-Based Serialization
Several CIS markets require additional security elements to be embedded alongside the serial number.
Required Data Elements
- Serial Number – 13 digits (AI 21)
- Verification Key – 4 digits (AI 91)
- Verification Code – 44 digits (AI 92)
Uzbekistan: Serial Number Prefix Restriction
In November, Uzbekistan announced an additional serialization constraint.
Exception is Serial numbers must start with the digit “7”
Brazil: ANVISA Medicine Registry Number
