GSRNP-96
Global Service Relation Number - Provider (96-bit)
urn:epc:id:gsrnpWhat is GSRNP-96?
Identifies a service relationship from the provider side. While GSRN identifies the recipient (the patient, the member), GSRNP identifies the provider (the doctor, the service agent) in the same relationship.
Used for: Identifying healthcare providers, service agents, or staff within a service relationship.
Field layout
The first 8 bits are always the header (0x2E = 46 decimal), which identifies this as GSRNP-96. The partition field determines how bits are divided between the company prefix and the following reference field - see the partition table below.
Defined in GS1 EPC Tag Data Standard v2.3, Section 7.9 (Global Service Relation Number – Provider), encoding procedure in Section 14.6.7.1.
| Bits | Field | Description |
|---|---|---|
0–7 | Header | 0x2E (46) - identifies this encoding as GSRNP-96 |
8–10 | Filter | Currently only value 0 is defined. |
11–13 | Partition | Splits bits between company prefix and service reference. |
14–53 | Company Prefix | GS1 Company Prefix of the service provider organisation. |
54–71 | Service Reference | Reference number for this provider relationship. |
72–95 | Reserved | 24 bits reserved. Must be zero. |
Filter values
The 3-bit filter field does not affect identity - it tells readers what packaging level or category the tag is applied to. The same item with different filter values has the same Pure Identity URI.

Partition table
The 3-bit partition value determines how the fixed bit space is divided between the company prefix and the following reference field. GS1 company prefixes vary in length (6–12 digits), so the partition tells the decoder where one field ends and the next begins.
