Dysgeusia is a condition in which a foul, salty, rancid, or metallic taste sensation will persist in the mouth. Ageusia is the inability to detect any tastes, which is rare.

The first three fields contain a total of 7 digits that identifies a block of 1,000 telephone numbers assigned to a wireless carrier. These 7 digits, representing the area code, exchange and 1st position of the telephone number, must be matched to the first 7 digits of the prospects telephone number.
In the international telephone network, the format of telephone numbers is standardized by ITU-T recommendation E.164. This code specifies that the entire number should be 15 digits or shorter, and begin with a country prefix. For most countries, this is followed by an area code or city code and the subscriber number, which might consist of the code for a particular telephone exchange.
