• WITH reference to Bloomsbury (Letters, ongoing), most London postal district numbers correspond to the main district names in alphabetical order.
Thus: NW2 Crickle-wood, NW3 Hampstead, NW4 Hendon. On that basis WC1 would be mainly Bloomsbury and WC2 Covent Garden. However, “District 1” tends to be an exception. (W1 and SW1), for instance, and seems best regarded simply as the most central postal area in any set.
