  1. It was from Bristol Central Telephone Exchange to the Lord Provost of Edinburgh, more than 300 miles away.
  2. It's Bedford. Ashford is 01233, Abingdon is 01235 and Hereford is 01432.
  3. It's one. London has the code 020, although local numbers then begin 3, 7 or 8.
  4. It's for TV and film. An episode of Dr Who revealed his mobile number to be 07700 900 461. Viewers who rang it would have received a recorded message saying the number was not recognised, at no charge.
  5. It's the Irish Republic. For example, Dublin was 0001. But since the late 1980s, the Republic has had the normal international access code 00, followed by 353.
  6. It's Reading. The successive changes caused some confusion at the time.
  7. The island off the west coast of Scotland, which is only 50 miles long, has three dialling codes - 01470, 01471 and 01478.
