For anyone who needs to arrange an NIE number in Spain fast!! Whether buying or inheriting property, setting-up a business, payment of taxes etc, obtaining an NIE number often needs to be arranged quickly and with a minimum of fuss.
However, that's just where the problems begin. The NIE service is run by the Spanish National Police or the diplomatic services and is therefore a slow process, usually taking weeks/months to arrange.
This can mean expensive delays for those who urgently need to address business or personal matters.
