If you’ve ever tried to call someone in Tanzania and wondered what those digits at the start of the number mean, you’re in the right place. International dialing codes can feel confusing at first, but once you understand the system, making a call to Tanzania becomes straightforward. Whether you’re connecting with family, friends, or business contacts, knowing the correct country code is your first step.
Tanzania is a vibrant East African nation with a large diaspora spread across Europe and beyond. For many people living abroad, staying in touch with loved ones back home is not just important—it’s essential. Let’s answer the most common questions about calling Tanzania so you can connect with confidence.
Which country has the international dialing code 255?
Country code 255 belongs to Tanzania, officially known as the United Republic of Tanzania. This East African country, which includes the mainland territory of Tanganyika and the island of Zanzibar, uses +255 as its international dialing prefix. Whenever you see a Tanzanian phone number written in international format, it will begin with +255.
Tanzania is one of the most populous countries in sub-Saharan Africa, with a rich cultural heritage and a growing economy. Its major cities include Dar es Salaam, the commercial hub, and Dodoma, the political capital. With a large and active diaspora community in Europe and North America, the demand for affordable calls to Tanzania is significant.
Understanding how country codes work
Country codes are part of the international telephone numbering plan managed by the International Telecommunication Union (ITU). Every country in the world is assigned a unique numeric prefix that identifies it within the global telephone network. These codes are used whenever you dial across international borders, telling the network which country you are trying to reach before routing your call.
Tanzania’s code, 255, falls within the African numbering zone. African countries are generally assigned codes beginning with 2, which is the regional identifier for the continent under the ITU’s system. This is why you’ll notice that many African nations share a leading digit of 2 in their country codes.
How do you dial a number with country code 255?
To call a number in Tanzania from abroad, dial your international access code (usually + or 00), followed by 255, then the Tanzanian area or network code, and finally the local subscriber number. For example, a full international call to Tanzania looks like +255 7X XXX XXXX for a mobile number.
Here is a step-by-step breakdown to make it easy:
- Start with the international exit code from your country (in most European countries, this is 00, or simply use the + symbol on your phone).
- Dial 255, the country code for Tanzania.
- Drop the leading 0 from the Tanzanian number if it has one (local numbers in Tanzania are sometimes written with a 0 at the start, but you remove this when dialing internationally).
- Enter the remaining digits of the Tanzanian phone number.
Tanzanian mobile numbers explained
Most phone numbers in Tanzania are mobile numbers, and they typically have nine digits after the country code. Tanzanian mobile networks include providers like Vodacom, Airtel, and Tigo, and their numbers follow recognizable patterns. For example, numbers starting with 74, 75, or 76 are associated with Vodacom Tanzania, while other prefixes belong to different operators.
When someone shares their Tanzanian number with you in local format, it might look like 0712 345 678. To dial this internationally, you would remove the leading 0 and add +255, making it +255 712 345 678. This rule applies consistently across all Tanzanian numbers, whether mobile or landline.
Tips for keeping your call costs low
International calls can add up quickly if you are not using the right service. A few practical ways to keep costs manageable include:
- Use a calling app that charges per second rather than per minute, so you are never paying for time you did not use.
- Look for weekly calling deals or promotional rates for specific destinations.
- Check whether the service you use has transparent billing with no hidden connection fees.
- Make sure the app you choose is available in your preferred language, so you always understand exactly what you are paying.
For members of the African diaspora in Europe, finding a reliable international calling service that offers fair rates and clear pricing can make a real difference in how often you are able to stay in touch with people back home.
