I reckon the long term plan is that 023 will become the Solent area, and the
codes inbetween (geographically speaking) will disappear when they need to
become 8 digit numbers.

As and when areas run out of numbers, the current plan is to introduce
"overlay" codes that will occupy the same area but have 8 figure
numbers.

023 will be used for the south of England. So, suppose that 01983 (Ryde)
runs out of numbers, then a new "Wight" area code will be created
consisting of 023 with 8 digit numbers beginning (say) 34. Existing Ryde
numbers will *not* be renumbered. If 01730 (Petersfield) runs out, a new
area code would be 023 with 8 digit numbers beginning (say) 61. And so
on.

024 has the same role for central England, 029 for Wales, and 037 to 039
for Scotland.
