Data Format & Required Fields

Code 128 with FNC1 encoding AIs (01) GTIN-14, (17) Expiry, (10) Batch, and optionally (7003) Expiry Date & Time or (7006) First Freeze Date for frozen goods.

Allowed Character SetGS1 Application Identifiers including cold-chain AIs (7003, 7006).

Payload Length Rule Between 6 and 48 characters

Required GS1 Structure Encodes standardized GS1 Application Identifiers (AIs). Unit-level and master packaging require primary identification (e.g. GTIN-14 or SSCC-18) combined with variable batch and serialization attributes for supply chain verification.

Check Digit / Checksum Rule Requires a verified modulo-10 check digit to prevent scanner misreads and data transposition errors.

Example Valid Format(01)00300012345671(17)261231(10)COLDLOT1

Industry Guidance & Practical Applications

Vaccine, insulin, and biologics cold-chain distribution cartons
Frozen meat and seafood master cases in HACCP-compliant cold stores
Blood plasma and diagnostic reagent transport labels (2–8°C)

Packaging & Scanning Notes: Adopted by Indian vaccine distribution network (Universal Immunization Programme) and global WHO EPI cold chain programs.

Symbol Constraints & Label Guidelines

Temperature AI fields require backend cold chain monitoring integration.
Label must meet WHO PQS label durability standards for frozen environments.
