OFFICIAL SITE OF THE STATE OF NEW JERSEYHPO numbering systems
Introduction
Both our online tools and in-person research are self-service. Researchers will need to use the following to navigate our collections:
Projects
Project/Log number
We assign a specific 6-digit project number to individual projects reviewed by our office. Each project number has a two-digit year number followed by a four-digit serial number (e.g., 24-0001).
Review Steps/IDs
If a 6-digit project number has an additional hyphen and number at the end, this references an individual step of the project. For example, we would label the third step in HPO Project Number 24-0001
as 24-0001-3
.
A single Review ID contains the parent project’s number but has a more specific meaning. Do not use them interchangeably.
Correspondence
HPO Chrono Numbers
Each individual piece of formal correspondence sent out by the HPO receives an alphanumeric Chrono consisting of a month, a year, and a serial number. Months are assigned corresponding letters (i.e. A for January, B for February, etc). For example, HPO would assign Chrono A2024-001 to the first correspondence sent out by the office in January 2024, and so on. This is an easy way to quickly find/reference individual letters, emails, and official documents.
The abbreviation before the main Chrono number may differ in correspondence from 1992 or earlier. Our office changed names several times between the 1970s and 1990s, so these all reference the same office.

| G | July |

| J | October |
| K | November |

Survey Reports
All survey reports in our collection currently use the following system. If you find references to shelf codes with “c.f.” suffixes or other characters that do not fit this system, please use DataMiner to search for the updated catalog reference.
- Shelf Code
- Shelving label for sorting by county, agency and series. Modern HPO shelf code references contain the county code, agency code, and accession number. If a report belongs to an existing series, it will have a lowercase letter after the accession number. Finally, if a report is one of multiple volumes, it will have a volume number (e.g., “v.2”) at the end of its shelf code.
- Year
- Publication date
- ID
- Report database ID number
- NJEMS
- NJEMS Project ID number
- Title
- Report name
- Preparer
- Firm or individual name
- Report Type
- Designation of the type of study conducted
- Location
- Collection or repository where the physical volume resides.
