The ECR Code

The Enhanced Correction Result (ECR) code describes the level of precision of the latitude/longitude coordinates returned for the address. The code consists of a prefix followed by a dash then the body of the code.

The prefix always begins with "EL" followed by a number from 1 to 5 indicating the overall level of precision:

• 5—Point geocode
• 4—Street centroid
• 3—Postcode centroid
• 2—City centroid
• 1—Region centroid

The body of the code identifies the components that were used to match the address to a geocode. Note that the body consists of letters and numerals. Here's what they mean:

• P—Premise/house number, building or PO box
• S—Street
• T—City
• R—Region/state
• Z—Postal code
• C—Country

There are only two numeric options in the body: 4 or 0

• 4—The component data was available to make the geocode-address match.
• 0—The component date was not available.

For example: EL4-P0S4T4R4Z4C4

In this example, the 0 following the P tells us that premise/house number data was not available to make this address match; everything from street to country, however, was used in the assignment.
