The following are the telephone codes in Tanzania.
The NSN length is nine digits.
Calls to Kenya and Uganda require a regional prefix rather than having to use full international dialling. To call Kenya from Tanzania, subscribers dial 005 instead of +254, while to call Uganda, they dial 006 rather instead of +256. To call Tanzania from Kenya and Uganda, subscribers dial 007 instead of +255.
Until 1999, Tanzania, Kenya and Uganda shared a telephone numbering plan, in which subscribers were only required to dial the trunk code, area code and number. In that year, Tanzania adopted a new numbering plan.

A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country.
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks.
In the United Kingdom, telephone numbers are administered by the Office of Communications (Ofcom). For this purpose, Ofcom established a telephone numbering plan, known as the National Telephone Numbering Plan, which is the system for assigning telephone numbers to subscriber stations.
In Argentina, area codes are two, three, or four digits long. Local customer numbers are six to eight digits long. The total number of digits is ten, for example, phone number (11) 1234-5678 for Buenos Aires is made up of a 2-digit area code number and an 8-digit subscriber's number, while (383) 123-4567 would be an example of a Catamarca number.
Telephone numbers in Hong Kong are mostly eight-digit. Fixed land line numbers start with 2 or 3, mobile (cellular) phone numbers with 4, 5, 6, 7, 8, or 9, pager numbers with 7 and forwarding service with 8. Since the end of 1989, there have been no area codes within Hong Kong.
Numbers on the Irish telephone numbering plan are regulated and assigned to operators by ComReg.
Telephone numbers in Singapore, also known as the National Numbering Plan, are regulated by the Info-communications Media Development Authority (IMDA). Due to the small geographical size of Singapore, there are no area or trunk codes; all numbers belong to one numbering area, and thus come in the same 8-digit format. Numbers are categorised based on the first digit, thus providing ten possible categories, of which six are currently in use and the remaining four reserved for future usage.
Widespread UK telephone code misconceptions, in particular brought on by the Big Number Change in 2000, have been reported by regulator Ofcom since publication of a report it commissioned in 2004.
The dialling plan for mobile networks and new landline operators is closed; all subscriber numbers must be dialled in full. For landline numbers starting with 02, the dialling plan used to be open; the trunk digit and area code could be omitted if the caller was in the same area code as the callee. However, starting May 3, 2008, all landline numbers must be dialled in full.
Telephone numbers in Malaysia are regulated by the Malaysian Communications and Multimedia Commission (MCMC).
Telephone numbers in Bulgaria are under a full number dialing plan, meaning that the full national number must be dialed for all calls, while it retains the trunk code, '0', for all national dialling. Area codes are prefixed with a trunk code of 0 only when dialled domestically.
Telephone numbers in Israel consist of an area code and a subscriber number. The dial plan type in Israel is closed, and "0" is the internal trunk prefix in Israel. Israel's country calling code is +972.
The regulation of telephone numbers in Germany is the responsibility of the Federal Network Agency of the German government. The agency has a mandate to telecommunications in Germany and other infrastructure systems.
Telephone numbers in India are administered under the National Numbering Plan of 2003 by the Department of Telecommunications of the Government of India. The numbering plan was last updated in 2015. The country code "91" was assigned to India by the International Telecommunication Union in the 1960s.
The following telephone numbers in Kenya are destination codes for international calls terminating in Kenya as well as the procedures for dialling internationally from within Kenya. Until 1999, Kenya shared its telephone numbering plan with Tanzania and Uganda, meaning that to make calls between the three countries, subscribers needed only dial the area code and number, a legacy of the East African Post and Telecommunications Corporation (EAPTC) which was dissolved in 1977. As a result of the reorganisation of Tanzania's numbering plan in that year, direct dialling was discontinued, although calls between the three countries do not require international dialling, only a special three-digit code.
National conventions for writing telephone numbers vary by country. The International Telecommunication Union (ITU) publishes a recommendation entitled Notation for national and international telephone numbers, e-mail addresses and Web addresses. Recommendation E.123 specifies the format of telephone numbers assigned to telephones and similar communication endpoints in national telephone numbering plans.
Namibia's telephone numbering plan was originally devised when the country, then known as South West Africa, was under South African administration, and integrated into the South African telephone numbering plan.
Telephone numbers in Georgia consist of 9 digits and follow a closed numbering plan in which the initial 2 or 3 digits indicate the service or area code and the remaining 6 or 7 digits identify the subscriber.
The Belize telephone numbering plan is the system used for assigning telephone numbers in Belize.
