E postcode area

The E (Eastern) postcode area, also known as the London E postcode area, is the part of the London post town covering much of the eastern part of Greater London, England and also Sewardstone in Essex. Since the closure of the East London mail centre during the summer of 2012, inward mail for the E postcode area is now sorted at Romford Mail Centre, with the IG and RM postcode area mail.
