<div dir="ltr"><div dir="ltr">Just to add my opinion on this, I would also agree with Jerry that addr:interpolation on a node/building with an addr:housenumber=1-5 would seem an obvious and logical way.<div><br></div><div>To reply to Mateusz, I think the situation in the UK may be different, as they note. There are several addresses I am aware of (at least in Scotland) where multiple buildings have been joined together into one (for example shops), and so these have one entrance and one address, but this spans a range of numbers, eg the postal address could be 5-9 High Street, but there are even numbers on the other side of the street. It would be incorrect to use multiple nodes in this instance, as there is no such address as 7 High Street.</div><div><br></div><div>Cheers, Donald </div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, 10 Dec 2020 at 22:03, Mateusz Konieczny via Talk-GB <<a href="mailto:talk-gb@openstreetmap.org">talk-gb@openstreetmap.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">
