Default Re: GPO exchange codes for charging dockets

I'm puzzled by the first list. It does not contain any specific tariff details but I can see it is biased towards the south of England (no Dundee or Motherwell). I assume it predates STD and was used for operator calls. How would they cope with charging for places not on the list (of which there are plenty)?

At the start of STD I recall calls were either local (L), up to 35 miles (a) or over 35 miles (b). I believe b1 was introduced later. Before STD was the charging far more complicated, like train tickets? Was it purely distance based?
