IG1 is the postcode for Ilford in the London Borough of Redbridge in East London.
The post town for this postcode is ILFORD.
In April 2005, a local businessman started a campaign to have the postcode changed to London E19, on the pretext that IG1 is not 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 [1].
