Communication in Tanzania

Kiswahili is Tanzania's dominant lingua franca, while government websites generally provide Kiswahili with an English switch. BAKITA supports standard Kiswahili, terminology, translation and interpreting. Local vernacular languages may be useful in daily life, but nationally consistent formal service coverage is not established. When a message is unclear, use Kiswahili where possible, ask whether English is available, and confirm names, telephone numbers, dates and deadlines in writing. Common channels include face-to-face conversations, mobile calls, SMS, USSD, WhatsApp, websites, email and post. Mobile wireless connections account for about 99% of internet subscriptions. In the fourth quarter of 2025, Tanzania recorded 58.1 million internet subscriptions; these figures count active subscriptions or fixed lines used for internet access during the previous three months, not unique people. Population coverage reached about 94.2% for 4G and 30.1% for 5G. Weak coverage, power cuts, lack of a suitable device or limited data can make voice calls, SMS, USSD, post or an in-person visit more reliable. UCSAF supports access in underserved rural areas; by January 2026, 758 towers had been completed across 1,407 villages and 713 wards, benefiting about 8.5 million people. The Electronic and Postal Communications (SIM Card Registration) Regulations 2025 apply to users and providers throughout the United Republic of Tanzania. Individual registration uses a National Identification Authority (NIDA) identity document and a fingerprint. Users must keep their PIN secret, report loss, notify the provider about a change of user or use, and never register a line with another person's identity document. Special procedures cover children, short-term visitors, visitors, refugees, diplomats, institutions, companies, machine-to-machine devices and people with missing or faulty fingerprints. Providers send an SMS showing the lines registered to a user, and shortcode 106 checks SIM registration. Biometric and identity data create privacy and identity-abuse risks, so do not share PINs or one-time passwords. Tanzania Communications Regulatory Authority (TCRA) data from June 2025 give an average basic voice price of about TSh 26 per minute on the same network and TSh 28 per minute to another network. A local SMS averaged TSh 7.80, while data averaged TSh 9.35 per MB; bundles were about TSh 2.12 per MB. Prices and promotions change, so check the current tariff with the provider. Shortcodes include 100 for customer care in Kiswahili, 101 in English, 112 for police or emergencies, 114 for fire, 116 for the child helpline, 117 for health, 190 for disasters, 111 for crime stoppers, 113 for anti-corruption, and 110 for water-body emergencies. Check current availability and service status when a number is needed urgently. Tanzania Posts Corporation (TPC) is the designated public postal provider with a universal-service role, while TCRA regulates postal and courier services. Licensed categories include public postal services, international courier, East African courier, domestic courier, intracity courier and intercity transport. A Tanzanian postcode has five digits and appears before the locality. An address may need a street and house number or a ward, village or hamlet, district and region. Depending on the delivery, a P.O. Box, poste restante or Private Bag may be more suitable. TPC offers Posta Kiganjani, digital tracking and courier services. Costs and delivery times depend on the product, delivery method and destination, so confirm them with TPC or the chosen provider. Government communication is coordinated through the e-Government Authority (e-GA), which supports standards and digital services. Government options include the Government Mobile Portal, Wananchi Portal, *152*00#, institutional portals and feedback channels such as *113# or SMS to 113 for corruption complaints. No single channel serves every public institution. Government websites should provide contact, telephone, postal or physical address, email, enquiry and feedback details. The responsible local government authority or institution handles the specific service, document or deadline. TCRA handles communications regulation, licensing, numbering, consumer protection and complaints. Consumers have rights to good service, service information, non-discrimination, complaint handling, safety, privacy, confidentiality, education, advance notice of suspension or termination, representation, invoice information and appeal. Users must pay on time, report faults and offences, protect infrastructure, use services lawfully and avoid harassment. Licensed providers must offer a free 24-hour call centre and access for people with disabilities. e-GA website standards refer to WCAG 2.1, alternative text, screen-reader support, clear links, adequate contrast and responsive design. SMS, USSD, email, post and in-person contact provide alternatives when a website or voice call is inaccessible. For a provider dispute, keep the contract, invoices, messages, reference numbers and other communication records. Escalate first through the provider and then to TCRA through a walk-in office, e-Mrejesho, *152*00#, dawatilahuduma@tcra.go.tz, the free 24-hour number 0800008272 or a letter. The TCRA Complaints Committee has a quasi-judicial role, and an appeal from its decision must be filed within 21 days. The Personal Data Protection Commission handles personal-data complaints and breaches. TZ-CERT handles cyber incidents through incidents@tzcert.go.tz or +255 22 2412039 during office hours from Monday to Friday, 8:00 to 16:00. Check official .go.tz or .co.tz contact details, because phishing, scams, SIM-swap fraud, identity misuse, tariff changes, poor coverage and misunderstandings can cause financial or personal harm.
