Identification of an individual flat in a building using Address Validate
I've checked the following address (which is valid with an appropriate postcode) using Address Validate
Addr 1 :16 Wythburn Court
Addr2 : 34 Seymour Place
Addr3 : London
Postcode : W1H 7NS
However, because the "Flat" is missing from the address, the 16 at the front is ignored and I get a "3-tentative full match" returned with the address amended to
Wythburn Court 34 Seymour Place London W1H 7NS
ie missing the precision of the flat number and therefore a deliverable address has been amended to an undeliverable one. I have tried with both standard and detailed components, individual address elements and a concatenation.
Checking the Royal Mail website gives me this as a format
Is there any way that I can get the flat number recognised?
