Places OS Open Names lists for JE3

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

Roads filed under JE3

OS Open Names covers Great Britain only and does not reach Jersey, so a street in JE3 cannot be confirmed from the register and the lookup answers about the postcode alone.
