2.0 Post Office
Locator API - External
3.1.1 Error
Response Parameters
This
document provides the definition of the USPS Web Tools Post Office (PO) Locator
Version 2 API. This service is considered a hybrid since both the WebTools
system and the PO Locator system, including an external location service
provider, are involved in processing the requests. The location, service, and
hour information maintained by the PO Locator system is a subset of information
maintained in the USPS Facilities Database (FDB) sources. The information is
updated on a regular basis, so that the information returned to the caller
reflects that which is maintained by the data providers.
The Web Tools Post
Office Locator API requires additional API permissions. Integrators should
contact USPS Internet Customer Care Center and follow the below instructions to submit a request for
Web Tools POLocatorV2Ext API access.

Hour Examples
Service hour information is returned as a set
of nodes, one for each day of the week. The content within the daily nodes
varies and may contain 0, 1, 2, or 4 elements.
Interpretation of this information depends on the service identified,
resulting in unique combinations used to identify specific situations.
A
typical response for a service is shown below. Monday will be used in all
format examples.
This
facility is open from 8:30
AM to 5 PM.
If
the facility closes for lunch, two sets of Open and Close times will be
returned.
This
facility opens at 8 AM, closed for lunch at noon, re-opens at 1 PM and closes
for the day at 3 PM.
Services
that only have one time associated with them, such as PO Box Delivery time and
Last Collection time, only the Close element will be returned.
This
service, likely to be PO Box Delivery time, has a completion time of 10 AM
If
the service is not offered for a particular day, the response will indicate
this with a null value day tag to indicate the service is not available on that
day.
