HPH Item Codes
The HPH Item Code is a coding system that uniquely identifies each item supported in the master HPH database. This coding structure was introduced to the industry in 1965. At that time, HPH and the industry realized that computer technology was going to significantly impact the business operations of the trade. HPH continues to use and maintain this coding system. It allows HPH to 100% positively identify items. Because HPH does not change codes, the HPH Item Code structure avoids many of the shortcomings and problems associated with other coding systems.
Unique Key
A complete HPH Code is unique. No two HPH database items will have the same Code. The fact that the HPH Code can be used as a stable database unique key allows HPH to develop, distribute, and maintain the industry’s most reliable databases.
Code Components
The HPH Item Code is a 10-character alpha-numeric string comprised of four components. An example code is shown below:
012NI0570D
012 – Group Number
NI – Manufacturer Code
0570 – Item Number
D – Suffix
Group Number
The first of the code components, the Group Number, is three characters and is used to define the type of commodity or general classification for the items. The materials/parts in the Plumbing/Mechanical trade were logically classified and assigned a Group Number. For example, all Wrot Copper Fittings are in Group 012.
Manufacturer Code
The Manufacturer Code is a two character designation identifying the producer of the items.
NOTE: To preserve the integrity of the coding system, the original Manufacturer Codes assigned to items are not changed when manufacturers are purchased or consolidated. For example, George Fischer purchased Sloane, but the HPH Codes for the Sloane items maintain the SL (Sloane) Manufacturer Code.
Item Number
This code component is a four-digit number assigned to individual parts within a group.
Suffix
The final component is a one-letter suffix. Although the Suffix is rarely used and is normally a blank space, it is included as part of the code to provide additional space for the addition of future items.
Benefits of using the HPH Item Codes
Logical Structure
The coding system is based on a commodity classification system that places similar items together.
Independent of Manufacturers
The codes do not require an effort, information, or financial support from manufacturers
Controlled by a Single Source
HPH is the sole entity responsible for the codes.
Codes Never Change
Once assigned, a code never changes.
Codes not Reused
Codes are never reused.
Widespread Use
The HPH Item Code has been deployed in the plumbing and mechanical databases for many decades. Software developers often use the codes for their databases because of its stability and reliability. With the increasing popularity of VDC / BIM, HPH codes are also included in most .itm and a growing list of RFA content.
