text: Walford has the postal district of E20. It was named as if Walford were part of the actual E postcode area which covers much of east London, the E standing for Eastern. E20 was entirely fictional when it was created, as London East postal districts stopped at E18 at the time. The show's creators opted for E20 instead of E19 as it was thought to sound better.
  In March 2011, Royal Mail allocated the E20 postal district to the 2012 Olympic Park. In September 2011, the postcode for Albert Square was revealed in an episode as E20 6PQ.
  Characters EastEnders is built around the idea of relationships and strong families, with each character having a place in the community. This theme encompasses the whole Square, making the entire community a family of sorts, prey to upsets and conflict, but pulling together in times of trouble. Co-creator Tony Holland was from a large East End family, and such families have typified EastEnders. The first central family was the combination of the Fowler family, consisting of Pauline Fowler (Wendy Richard), her husband Arthur (Bill Treacher), and teenage children Mark (David Scarboro/Todd Carty) and Michelle (Susan Tully). Pauline's family, the Beales, consisted of Pauline's twin brother Pete Beale (Peter Dean), his wife Kathy (Gillian Taylforth) and their teenage son Ian (Adam Woodyatt). Pauline and Pete's domineering mother Lou Beale (Anna Wing) lived with Pauline and her family. Holland drew on the names of his own family for the characters.
