PRECASS Instructions

Overview

When you upload a file to the precass processor, you will not lose any of your original data. The process will create four new fields in your data file:

city2 – Given the address, this will be the city that the system is most confident in replacing your original with.
state2 – Potential State Replacement.
postcode2 – Potential Postal Code or Zip Code replacement.
confidence – This is the confidence level that the system is assigning to your data, or to the suggested replacements.

Confidence

The confidence is based on the data provided in other fields based against our list of Zip Codes, Cities and States. The better the match, the higher the confidence that the data is valid.

Uploading Your Data

PRECASS currently supports only the city, state and zip/post code fields for validation. When uploading a file there should be only 4 columns:

id – This is the value that maps back to your actual address book record.
city
state
postcode

Retrieving Your Results

Once your file is uploaded, it is assigned a job code which will look like:

62tig6iz6v5s7tzzgnl

This job code will be part of a URL that you will be given to check on the status of the file. It will either be queued, processing, or complete. When the file is complete, it will also provide a download link.

Roadmap

Currently, we are testing the City/State/Zip (CSZ) validation routine of the PRECASS processing engine. We are working on incorporating the openaddresses.io dataset into the processor in order to validate most US street addresses.
