I don't have a map of Saudi Arabia in front of me as I write this.
Could it be the other way around?  (I.e., could you have 3 as city
code for Dhahran and 87 as an "exchange" reserved for Aramco there?)
Here is what I have for Saudi Arabia city codes:

966 Saudi Arabia
	1  Riyadh
	2 or 21 Jeddah
	2 or 22 Mecca
	41 Medina

Saudi Arabia is divided into six regions. Each region is given a
unique area code:

  01 Riyadh region
  02 Jeddah region
  03 Dammam region
  04 Medina region
  06 Qassim region
  07 Southern region

Within the area only the subscriber number have to be dialled. The
subscriber number consists of seven digits. The area code and the
subscriber number is always nine digits.

   0A - NXX XXXX

0 is used as national prefix.

00 is used as international prefix.

All numbers starting with 9 are reserved for different emergencies and
special services. All these numbers are three digits long. (example:
Police 999, English clock 963)

The local exchange is identified by the NXX-code (A local exchange is
allocated 1 to 4 NXX-codes). According to my list of NXX-codes 871 is
given to the PABX for the railroad company, Aramco (Dharan) is given
874, 875 and 876, and 879 is the Dharan airport PABX. (The railroad
and the airport switches are of the type SXS).

According to the list Aramco has several more NXX-codes in the Dammam
area.
