Actually as I said before it's more than three
212 = Manhattan
646 = Manhattan Overlay + Cellphones
917 = Cellphones now being used for landlines
718 = Brooklyn, Queens, Bronx, SI
347 = Brooklyn, Queens, Brons, SI Overlay + Cellphones
Then there are the "upstate" area codes.
Admittedly some of the more sparsely populated states have 1 huge area code with separate ones for cities, but most states have a whole bunch now.
The UK could still adopt a similar model, preparing in advance allocating 1 major county code, then 4 or 5 for large urban areas.. Cities like London, Manchester etc could have their own block of 10 That would give up to 10 million numbers for each city alone.
The 555 range is used to some extent. 555 1212 for example is out of state directory inquiries.

(A classic example of such a nuisance is the 1982 song 867-5309/Jenny by Tommy Tutone, which is still the cause of a large number of nuisance calls.) However, not all numbers beginning with "555" are fictional—for example, 555-1212 is the number for directory assistance in many places. In many, but not all areas, dialing "555" numbers other than 555-1212 will actually get you to directory assistance as well. In fact, only 555-0100 through 555-0199 are now specifically reserved for fictional use, with the other numbers having been released for actual assignment. Some movies have started to use fictional telephone numbers starting with "1", giving someone a "telephone number" of 167-1402 in the film, for example.”
