The IG postcode area, also known as the Ilford postcode area, is a group of 11 postcode districts in England, which are subdivisions of six post towns. These postcode districts cover parts of eastern Greater London and southwest Essex. Inward mail for the IG postcode area is sorted at the Romford Mail Centre, with the E and RM postcode area mail.
In April 2005, a local businessman started a campaign to have IG1 postcodes changed to London E19, on the pretext that IG1 is not always recognised as a 'London postcode'. He argued that so doing would help local businesses. A Royal Mail spokesman, however, said campaigners in Ilford had "virtually no hope" of changing their postcode. This had previously been raised by the then Greater London Council politician Serge Lourie in the 1970s and similarly rejected. Ilford had been removed from the London postal district in 1866.
