Geocoding API FAQ

PO Boxes

Q: Does the Geocoding API set-up to standardize PO Boxes?

A: No we do not standardize PO Boxes.

Q: Does the Geocoder API validate if a PO Box exists?

A: The geocoder does not validate the PO Box - if someone provides us a PO Box that does not exist, for example "PO BOX 10000000, Irvine CA", the geocoder will not tell whether that box is valid or invalid according to USPS.

Q: What is the coordinate precision that is returned for a PO Box?

A: The best that the geocoder can do for a location is to return a ZIP Code accuracy x/y for the location - e.g. if someone geocodes PO Box 3, Troy NY 12180 we will return back the location for 12180.

Q: How many decimal places do you carry for a geocode address response coordinate

A: The coordinates for our geocoder are rounded to 6 decimal places. Which is an 11.1cm accuracy.

Q: Do we have Delivery Point Validation (DPV) from USGS in our geocode response?

A: At this time we do not carry Delivery Point Validation (DPV) on our geocode response object
