Exit code or plus format
On a mobile phone, the plus sign usually replaces exit codes such as 00 or 011. From a landline, use the international access code for the country you are calling from, then 255.
Country calling code, dial code, or prefix
People may call 255 the Tanzania country code, country calling code, phone code, dial code, or international prefix. In each case, use +255 before the rest of the Tanzania number.
Mobile phone or landline
