The protocol for data entry for street names is basically the same as that for the entry of correspondence surname (paragraph 2.2). For Street Name purposes they are:
(a) where applicable hyphens without spaces are permitted;
(b) where applicable apostrophes between letters are permitted for street names (eg L'STRANGE);
(c) where applicable appropriate spaces between letters are permitted for street names
(eg DE BOAR GROVE, LE STRANGE CT);
(d) commas or full stops are not permitted.
