EastEnders' postcode for 2012 park
The Olympic Park is to get the same postcode as the television soap EastEnders, the Royal Mail has said.
An E20 postcode is being introduced for the destination in Stratford, east London.
The postcode will serve five new neighbourhoods to be created after the 2012 Games, when the site will be renamed the Queen Elizabeth Olympic Park.
The Olympic Stadium will get its own postcode of E20 2ST and more than 100 postcodes will be assigned to developments throughout the Park. Each postcode covers up to 99 addresses.
Until now E20 had been a fictional London district of Walford, home of Albert Square in the television soap EastEnders.
London's first postal districts were introduced in London in 1857, while the current way of using letters and numbers to create postcodes was introduced in the late 1950s.
The E20 code for the Olympic Park will also cover neighbouring areas including the residential apartments in the Athletes Village plus the Westfield Stratford City shopping Centre which will house 400 retail units. The postcodes will be split into three zones - E20 1, E20 2 and E20 3.
There is also the chance that zones 4-9 could be added in future decades as the site develops. Up to 8,000 homes will be built over the next 20 years. The first three sectors could cover delivery postcodes for 120,000 addresses.
Stephen Agar, Royal Mail's director of regulated business, said: "It is fitting that such a significant development in London has been allocated its own easily recognisable postcode more than 150 years after the world's first postcodes were introduced in the capital."
Andrew Altman, chief executive of the Olympic Park Legacy Company which will manage the Park after the Games, said: "This is a new postcode for a new part of London. E20 will be one of the capital's most popular districts focused on community-living, sport and entertainment."
