Remarks	Note: The results listed above reflect the default match sensitivity (85).
	Note: To obtain optimal results, before performing data cleansing on phone numbers, the area code or governorate (which are often stored in databases separately from the base number) should first be concatenated with the base number.
	Note that the number of digits retained in the match codes is a function of the number of digits in the base number and the match sensitivity. Governorates match their corresponding numeric area codes. Eight-digit (Cairo) base numbers match whether the 02 area code is present or not.
