Address validation service

Element type: Required

Endpoints/models used: ResolveAddressPost or some other third-party validator

Your integration must include a method to validate an address in the UI wherever addresses are entered. You can use the Avalara address validation service or some other third-party validator. If you plan to use the Avalara address validation service, then use the ResolveAddressPost API.

Address validation certification requirements are called out in the badge requirements page.

Note

Avalara's address validation service doesn't currently provide autocomplete or suggestions when users input an address.
Avalara's address validation service supports only U.S. and Canadian addresses. If you use the Avalara's address validation service, we disable address validation in your UI if a user inputs an address outside of the U.S. or Canada.

Tip

A validated address provides you with the best tax result; an unvalidated valid address will still likely get you a tax result, but it may not be as accurate as the validated result.

The following example shows how to call the ResolveAddressPost API.

curl
  -X POST
  -H 'Accept: application/json'
  -H 'Authorization: Basic ${btoa(`:`)}'
  -H 'Content-Type: application/json'
  --data '{
    "line1": "2000 Main Street",
    "textCase": "Upper",
    "city": "Irvine",
    "region": "CA",
    "country": "US",
