How to dial a number for Egypt

The Country code for Egypt is +20 (or 0020) if you are dialing from outside Egypt. Affix this before the rest of the Number.

How to dial the rest of the Number?

Jack puts it very well when he says:

There are 2 things to remember/realize

1. your mobile number is prefixed with a 2 digit "city code" or "area code" plus a "0" that indicates a "long distance" number

The ones I know of are 010, 012 and 016

If you are from the US, think of this as your area code.
If you are from elsewhere in the world, think of it as your city code.

Coming to dialing a landline number in Cairo from your mobile phone :

No matter what your mobile phone number is, if you are calling a land line, you need to tell it what city you are calling to.

So, the "city" code for Cairo is "2".
You need to dial ZERO first, to indicate a "long distance" or outside your "city", then the city code.

So to dial a landline in Cairo you dial

02

If you wanted to call a number in Alex, which has a city code of "3"
you would dial:

03

2. The 2nd thing to remember is that recently (6 months ago?) the government added a new number to the FRONT of land lines in the Cairo area.
Phones in some parts of the city , a 2 was added. In some parts, a 3.

So in Zamalek, Mohandaseen, Agouza, Dokki (and I think downtown) a phone number that used to be
735-1234
is now
2735-1234

So, if the number you have for the bus station (or anybody else in Cairo) has only 7 digits, you need to prefix it with either a "2" or a "3"

FURTHERMORE, if you are dialing from a mobile, you need to prefix the city code "02"

So to call the fictional number I mentioned earlier.

735-1234
you need to prefix the new 2
2735-1234

and then the city code.

So the full dialing instructions from an (Egyptian) mobile phone would be
02 2 735-1234



Basel adds :
Egypt International code: from USA or Canada 011 then 0020 from rest of the world 0020 except Bahrain (maybe they have changed it not sure) just one zero i.e., 020

Greater Cairo City (Cairo + Giza + Qalyoubeyyah) code 02 and Alexandria City code is 03 ... etc

Mobiles codes Vodafone 010 and 016, MobiNil 012, and Etisalat 011

It is a coincidence that Egypt international code is +20, i.e., zero at the end so a whole number in Cairo would be +20-2-87654321 by eliminating the zero before the city OR mobile code and adding the international code

0020
03
34567890

=

From abroad: +20-3-34567890 (from mobile or landline)
From Cairo: 03-34567890 (from mobile or landline)
From Alexandria: just the 8 numbers of the person u r calling, i.e., 34567890 (from landline)
From Alexandria: 03-34567890 (from mobile)

To call a mobile number:

From Cairo to Vodafone number: 010 or 016-7654321
From abroad: +20-10-7654321

Exception Exception exception exception exception
for the numbers of the "Smart Network" like 19519 Pizza Plus or 19991 McDonald or 16516 Cairo Yellow Cab (Taxi), you just dial the number no matter where you are in Egypt or what mobile operator you are using, just dial the five digits and you will be connected to the nearest office or branch.

HOWEVER, sometimes when you use your mobiles, and if the service is for Cairo only, you dial 02-19019 from your mobile.
