The transformation parses building numbers or house numbers from street information before it performs validation. Otherwise the transformation validates the input address elements strictly according to the input port structure. The narrow option performs the fastest address validation, but it can return less accurate results than other options.

The transformation uses the standard parsing settings and performs additional parsing operations across the input data. When you select the wide option, the transformation updates an address if it can match at least one input value with the reference data. The wide option increases mapping run times.
