This service has some configuration that will be discussed with you as part of the on-boarding process. We can configure a matching profile and which sources of information to use when calculating a 2 plus 2 check. Please contact W2 Support for more information.


The following Query Data properties pertain to this service. Please note that in the SOAP request the fields must be in alphabetical order.

  • Address information is optional if an AddressLookupRef is supplied in the query options. The AddressLookupRef is retrieved from the W2 Data Address Lookup 024 service as an addressId.
  • If an AddressLookupRef is not supplied then a minimum of House Name/Number and Postcode are required. Though it is advised to supply as much address information as possible as this is more likely to return a match if no prematched addressId is supplied.

Response breakdown

The following shows the basic schema for the W2DataEkycUk007BResult result.

Below is some more information about some of the elements of the response that require explanation:

DataSources = A collection showing every source of data that was used to formulate the result. Each source is represented by a MatchingSource element.

AllowMultipleRecordsAsSeparateDataSources = Indicates that two different record matches from the same data source may count as independent sources when formulating the 2 + 2 result. For example, two Insight results may count as two sources, rather than one, as they would do under normal service circumstances.

MatchingCriteria = Precisely what data has been matched by the data source. E.g. NameAndAddressAndDateOfBirth

NumberOfMatches = The number of matches found by this data source

Source = An integer representing the source of the data match. E.g. 2 = CCJ (County Court Judgement)

SourceIdSource Matched
1Electoral Roll
2County Court Judgements (CCJs)
4Credit Lenders (Insight)
6Mortality Data
7Credit Lenders (Call Credit)

InterpretResult = The overall verification result, based on what matches were found in the data source against the query data submitted. The possibilities are Pass, Fail or Refer

Message = Gives some more details / context on the verification result

TransactionResult = A diagnostic result showing whether or not any technical errors were experienced during the check. This should always be "Success" unless a technical error has occured, in which case the verification check will be aborted.

A warning occurs when a verified response returns an address variant that is different to the request that was sent.

This will now display several warning messages that identify the verified response, the supplied response and where this differs.

Below are the properties that will display if any address variance occurs, then these will be displayed :
