Vacancy Data

Regrid is excited to provide USPS vacancy data nationwide at the parcel level - something that to our knowledge has not been done before.

While aggregated USPS vacancy data has been used in academic studies and research since at least 2010, there hasn't been a way to crack that data open and see how those aggregations have been made, or how reliable the data is. We are able to offer this information right at the parcel level for granular insights.

Vacancy Data FAQs, Disclaimers & Limitations

What is the USPS Vacancy & Residential Data?

The United States Postal Service maintains a database of every deliverable address in the US.

This data is collected and maintained by their letter carriers.

As part of their regular processes, letter carriers identify addresses as either primarily residential or non-residential delivery points. That information is recorded as what the USPS calls their "Residential Delivery Indicator" (RDI).

There are times when the letter carriers record addresses that are valid addresses, but for some reason are not currently collecting their mail. This is recorded as a "Vacant Flag". It is important to understand these addresses could receive mail, but are not currently receiving mail. This is different from addresses that are not considered valid for receiving mail, for example addresses that might be assigned to new developments where buildings have not been built or are not yet occupied.

What is the current match rate on regrid.com?

• • • ~89 million parcels currently have USPS data attached.
    • We have ~117 million addresses in our dataset and we have matched approximately 89 million of those addresses for a total match rate of 76%.
    • As this is our initial pass over the parcel addresses in our dataset, we expect to increase this number on subsequent passes over our dataset.
    • Additionally, counties typically only maintain 1 address per parcel and a significant percentage of those parcel addresses are non-deliverable parcels like farm fields or other vacant lands.

How Frequently Will This Data Be Updated?

• • • USPS data will be updated approximately every month as and when it is released by the USPS Certified Data Vendor we work with. 

What are the limitations of this data?

• • • The USPS data is only available in our dataset where we have parcel address data, which is not the entire dataset. As a result, there will be a few places that may not have the USPS data.
    • We currently don’t have buildings and unit-level USPS data. We typically only have one unit per building, even if it's an apartment building so mileage on the USPS data may vary in high-density areas. So as a result, the vacancy indicator may apply to one or a few units within an otherwise occupied multi-unit dwelling.
    • We have integrated this data as-is into our dataset. USPS data itself can vary in accuracy. So please be aware that there might be some discrepancies with this data occasionally.
    • USPS data is updated every month and we will do the same. The data may be inaccurate between updates due to changes in occupancy or demolitions that will not be reflected until the next data refresh.
    • We will be working to ground truth and improve the accuracy of this data moving forward. If you have observations about the USPS data in your area that you'd like to share with us in an effort to refine and improve the information, please get in touch by emailing help@regrid.com or via the 'help widget' on our site.
      
      We know that the data is not perfect - and we hope you get in touch with us to share your findings, so we can refine this dataset going forward. The Regrid Team feels that this is an essential tool for our friends and partners to have, and a revolutionary step forward in understanding the property dynamics in our communities.

What are the limitations for usps data usage as a regrid customer?

• • • This data is available with our paid mapping subscriptions (Pro and Team) and are contained in our Premium Schema for those interested in getting access via licensing bulk data or our API. Please contact us to get a quote & a data sample.
    • We request our customers not to use the data for direct mail commercial marketing campaigns.
    • Pro users can view, filter & style the USPS fields. However, Pro users will not be able to download the USPS data in any format. Team customers can view & export up to 50K rows of USPS data as a CSV.
