  - International Addressing Services
    The international addressing services standardize and validate addresses using postal authority address data. This service can correct information and format the address using the format preferred by the applicable postal authority. It also adds missing postal information, such as postal codes, city names, state/province names, and more.

Performance Hints

The performance parameters related to the Global Type Ahead service are listed below.

Use AutoComplete control with a built-in delay and minimum length. A delay of 200 ms and a minimum length of 5 typically works well.
While a user-oriented delay setting provides the best performance compromise between User Experience and Performance, a simpler alternative is to send API requests every other character typed.
The default number of candidates to return is 10. You may increase this up to 99, although it may slow down the typing experience's perceived performance.
Global Type Ahead API will only return results once the input is complex enough to return a meaningful response.
For example, an input of '12' will not return the first 10 addresses that start with 12. There needs to be a fragment of a street name included with it, such as '12 Cot'.
If you are calling with JavaScript and using REST GET, most browsers will cache pre-flight checks based on the URL, not the domain. As typeahead changes the URL with each character typed, the browser will likely call a pre-flight check with each call. To get around this, use REST POST as the URL will remain the same.
