These are the access codes for international direct dial that I know of:

Algeria		00
Austria		00
Belgium		00
Cyprus (Rep) 	00
Czechoslovakia	00 (from Prague; elsewhere dial Prague followed by 00)
Denmark		009
Finland		990
France		19
Germany (West)  00
Gibralter	00
Greece		00
Hungary		00
Italy		00
Luxembourg	00
Malta		0
Morocco 	00
Netherlands	09
Norway		095
Portugal	00  (07 in some areas)
South Africa	09
Spain		07
Sweden		009
Switzerland	00
Tunisia		00
Turkey		99
United Kingdom	010
United States 	011
Yugoslavia	99

00, whether more logical or not is certainly the most widespread, at
least in Europe and the Med.

Sweden will before the year 2000 change the international direct dial code
from 009 to 00. So will probably most other countries in Europe, thereby
following international recommendations.
Sweden will also prepare to use the 11x number for emergency calls etc.
We now use 90000 for emergency call. This also follows international
recommendations. This change may take much longer time as it effects
houndreds of thousands of subscribers whose numbers start with 1.

It's because 00 is recommended by CCITT as the international prefix.

| When dialing into a country from outside, the leading zero must be
| stripped off the area code.

Strictly speaking, that 0 isn't part of the area code (called `trunk code'
by CCITT); it's the trunk prefix code.  Again, CCITT recommends using 0.
Some confusion might be caused by the CCITT national number format, which is

	(trunk code) subscriber number
or	(trunk prefix + code) subscriber number

In the USA, we never put the trunk prefix in the parens, but other countries
often do; thus, (020) 22 88 28 in Amsterdam is really trunk code 20.  The trunk
prefix is never dialed in international dialing.

The E.100 series of CCITT recommendations talks about this stuff.

The UK code for international direct dialling (IDD) is 010, as opposed to
00 as adopted by many European countries. The reason for this, I believe, is
as follows:

In the days before IDD, <00> was used as a "special" STD code for calls from
 the UK (including Northern Ireland) to the Republic of Ireland. When IDD came
along, it would have been politically insensitive (suicidal?) to make Eire
calls "international", and rather than mess about changing existing codes and
routings, the 010 had to be adopted for the IDD prefix.

Is this history correct? I wouldn't be surprised if the cause of a common
European IDD prefix is yet another victim of the mess that is Anglo-Irish
politics :-(

That is still the case.  For example, the Dublin number (01) 234567 is dialled
as 0001 234567 from the U.K. However this is not the case for all area codes.
The Irish phone book has a table which translates an Irish area code into a
code that is dialled from Northern Ireland (it dosen't mention the rest of the
U.K. but I have experience with 01 -> 0001 so I assume its the same). Most are
really strange. e.g.

        01      0001
        021     0002
        022     010 353 22      (note 353 is international code for Ireland)
        041     0011
        042     0004
        071     0015
        078     0010

To dial a U.K. number from Ireland it is much simpler, e.g. the London number
01-234 5678 is dialled as 031 234 5678. The rule is that the U.K. area code is
prefixed with 03 except when it is is 0N (n=1,2,3,4,5,6) in which case it
becomes 03N. The cellular access codes are given as Cellnet=030860,
Vodaphone=030836 (I assume they already include the 03).
