IM postcode area
Postcodes were introduced in the Isle of Man in 1993, with the island becoming the IM postcode area. Each town or area is associated with one or more postcode districts, assigned by Isle of Man Post Office. Outside the larger towns, the postcode districts are further broken down and each postal sector is assigned to a number of villages and settlements. Coverage
The approximate coverage of the postcode districts (and sectors, where relevant) is as follows. In each case the post town is "ISLE OF MAN". The "coverage" column includes the next digit of the post code (the sector). See also
