The tLoqateAddressRow component outputs an ACCURACYCODE column. This column holds the verification codes for processed addresses.

The verification code is made up of the following values:

Verification code values

Description

The verification status

used to specify the full mailing address in the relevant country.

The post-processed verification match level.

used to specify input data for the address line in the relevant country, split into individual address lines.

The pre-processed verification match level

used to specify the full address including line breaks without the Organization, Locality, AdministrativeArea and PostalCode fields.

The parsing status

used to specify the individual lines contained within the DeliveryAddress field.

The lexicon identification match level

used to supply the country name or code.

The context identification match level

used to supply the ISO 3166 official country name.

The postcode status

used to supply the ISO 3166 2-character country code.

The matchscore

used to supply the ISO 3166 3-character country code.

For example, the V44-I44-P3-100 verification code implies:

  • Verification status = V (verified): a complete match was made between the input address and a single record from the available reference data.

  • Post-processed verification match level = 4 (premises): the level to which the input data matches the available reference data once all changes and additions performed during the verification process have been taken into account.

  • Pre-processed verification match level = 4 (premises): the level to which the input data matches the available reference data prior to any changes or additions performed during the verification process.

  • Parsing status = I (identified and parsed): all components of the input data have been able to be identified and placed into output fields.

  • Lexicon identification match level = 4 (premises): using pattern matching, a numeric value or word has been identified as a premise number or name.

  • Context identification match level = 4 (premises): using a least accurate form of matching, a numeric value or word has been identified as a premises number or name.

  • Postcode Status = P3 (added): the primary postal code for the country has been added.

  • Match score = 100 (complete similarity): the input data and closest reference data match completely.

The following sections explain in more details all segments of the verification code.
