GID-96
General Identifier (96-bit)
urn:epc:id:gidWhat is GID-96?
A general-purpose EPC scheme not tied to GS1 keys. Uses an EPCglobal General Manager Number instead of a GS1 Company Prefix. Designed for organisations that need EPC encoding without using GTINs, SSCCs, or other GS1 identifiers.
Used for: Non-GS1 applications, proprietary asset tracking, research and prototyping.
Field layout
The first 8 bits are always the header (0x35 = 53 decimal), which identifies this as GID-96.
Defined in GS1 EPC Tag Data Standard v2.3, Section 14.6.12.1 (General Identifier), encoding procedure in Section 14.6.12.1.
| Bits | Field | Description |
|---|---|---|
