W1.5 - Using US address correction

Previous Article matchIT Web Index Next Article 

The US correction is seamlessly integrated into the data entry fields in the search pane by default. The operation of this functionality is designed to be as smooth as possible, so the design and order of these fields help with the process.

 

There are in fact, two checks for address, the as you type address correction, which will prompt you with possible values and auto-fill where it can, and also a recursive check prior to entry into the database, which will give you any last suggestions and allow the user to pick what they typed, or the possible corrected value.

 

To use the as you type address correction, tab into the ZIP field, this is where the and key in a five digit ZIP code then tab out of the field. The ZIP code needs to be the first field captured, because this initiates a search of the USPS database to cache candidate addresses which will help us auto-complete the rest of the address.

The address correction service will take this information and determine if there is a city and state it can return for this ZIP code.

In some cases, the ZIP code may not be valid, or it cannot be resolved down to just one city or state.

Where this is the case, you will see a warning sign which indicate that at this point, the US address correction service can’t complete the indicated field at this time. This is not a problem, just tab to the street field and continue typing.

 

The street field features auto-suggest to aid in completing the first line of address. As you type in the street line and get to the fifth character, a drop down will appear to guide you through the recognized values.

 

 

You can select a value by using the arrow keys to navigate to the correct value, then press enter or tab to select the value. As a note, the first line of address check will check against the CASS database to ensure that it lies within an accepted range for the selected street. In the example above, 400 Patch Ave is valid, however 600 Patch Ave is not in an accepted range, so as you type, you will not be given any choices to select, and you will need to complete the field manually.

 

Once you have completed the street line, a few different things can happen, according to what has been keyed.

 

You will see the ZIP code updated to feature a ZIP+4 code and no further action is required.

 

You can still type a suite or apartment number in if you want to, however the address is deliverable without this additional information, it doesn’t explicitly need an apartment or suite number for this address to be a deliverable address.

You will see the ZIP code updated with a ZIP+4 code, however you will also see a warning sign against the Apt/Suite field.

 

What this indicates is that the current address is set to a default ZIP+4 code for that address, which is deliverable, however, you need to add in details for a sub-premise if the address is to be an explicit delivery point. The default ZIP+4 code is usually assigned to properties where there are multiple units or apartments.

 

By adding in the required sub premise information, you will be able to find a specific address delivery point, the ZIP+4 will be updated and the warning will disappear. To indicate the sub premise information is valid, a green tick will appear beside it.

For records where the first line of address was not recognized as deliverable, no ZIP+4 code will be assigned and there is no prompt for a sub premise. The US address correction service has noted there is already a problem rationalizing the address to a delivery range, so it can’t offer any further information. The Street line of the address will feature the warning icon and the user can still go ahead and enter an apartment or suite number, however this wasn’t verified.
