Places OS Open Names lists for JE4

OS Open Names does not cover Jersey, so it lists no place for the district's postcodes.

Roads filed under JE4

OS Open Names covers Great Britain only and does not reach Jersey, so a street in JE4 cannot be confirmed from the register and the lookup answers about the postcode alone.
