US Address Client

Ruby Client to call the privately hosted US Postal Address Service to verify and cleanse addresses.

Status

Not for production use. US Postal Address Service is not yet open source to be able to use this client.

Examples

Verify and cleanse an address:

address = USAddressClient.verify(address: "2811 Safe Harbor Drive", city: "Tampa", state: "FL", zip: "33618")
# => #<USAddressClient::Address:0x00007feab8c06570 @zip="33618", @time_zone_code="05", @time_zone="Eastern Time", @suite_range="", @suite_name="", @suite="", @suffix="Dr", @street_name="Safe Harbor", @state="FL", @result_codes=["AS01"], @private_mailbox_number="", @private_mailbox_name="", @pre_direction="", @post_direction="", @plus4="4534", @melissa_address_key_base="", @melissa_address_key="", @garbage="", @delivery_point="33618453411", @city="Tampa", @address_type_code="S", @address_type="Street", @address_range="2811", @address2="", @address="2811 Safe Harbor Dr">

Customizing what is a good or bad address

Melissa Data returns good and bad codes after verifying the address.

By default the following codes need to be returned before the address is considered valid:

AS01
AS02
AS03

To override these codes, set the good_codes value in secret config as a list of comma separated values:

us_address_client:
  url:          http://address.service.test.com
  good_codes:   "AS01, AS02, AS03, AS20"

Even if a good code is returned, by default the following codes will force the result to be considered invalid:

AC02
AC03

To override these codes, set the bad_codes value in secret config as a list of comma separated values:

us_address_client:
  url:          http://address.service.test.com
  bad_codes:    "AS03, AS09, AS16, AS17, AS24, AE01, AE02, AE03, AE04, AE05, AE07, AE10, AE11, AE12, AE13, AE14"
