Ways to dial

Various methods to call Tanzania

Several routes connect you to Tanzania (+255) landlines, calling cards and modern VoIP services. Pick the one that fits your call volume and budget.

01

Calling Tanzania from a landline or mobile

Dial your exit code (00 from most countries, or 011 from North America), enter +255, then the local Tanzania number — dropping any leading 0. Tanzania's 3-digit country code puts it in ITU Zone 2 of the global E.164 numbering plan.

See dialing steps→Classic
02

International calling cards for Tanzania

Tanzania uses a 3-digit country code (Zone 2). Check that the card lists +255 rates explicitly — mobile numbers in Tanzania often carry a different per-minute charge than landlines. Factor in the Africa/Dar_es_Salaam time zone when planning the call.

See dialing steps→Pre-paid
03

VoIP services for contacting Tanzania

Apps like Skype, WhatsApp and Viber, and business VoIP from TKOS are the cheapest route to Tanzania (+255) — routes to Tanzania use trans-Atlantic and trans-Indian Ocean cables — latency under 200 ms is typical on a good connection.

Cost breakdown

Cost analysis for calling Tanzania

The cost of calling Tanzania varies depending on the method and service provider you choose. Compare landline, VoIP and calling-card routes side by side.

VoIP · overview

Cheapest route to Tanzania — internet-based.

  • VoIP is the lowest-cost way to call Tanzania (+255) — app-to-app calls over Wi-Fi are often completely free.
  • Trans-Atlantic and Indian Ocean cables serve Tanzania — a wired ethernet connection removes most packet-loss risk on these longer international routes.
01

Pick a VoIP provider

Choose TKOS for business-grade calls to Tanzania, or consumer apps like Skype, WhatsApp or Viber for casual chats.

02

Create and verify your account

Sign up with an email or phone number, then verify your identity if required.

03

Add credit (if calling regular phones)

App-to-app calls are usually free; calls to mobile/landline numbers need a small balance or a subscription plan.

04

Dial +255 + the local number

Enter +255 followed by the Tanzania subscriber number (drop any leading 0).

05

Place the call from any device

VoIP works on phones, laptops, tablets and desk phones wherever you have internet.

06

Monitor call quality

If audio drops, try switching from cellular to Wi-Fi or move closer to your router.

Tips for clear & uninterrupted calls

Whether you're reaching Tanzania for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.

  • 01

    HD audio for Tanzania calls

    Tanzania routes (Zone 2/Africa) can carry higher jitter — a headset with active noise cancellation compensates for audio artefacts without you needing to do anything.

  • 02

    Connection quality to Tanzania

    Trans-Atlantic and Indian Ocean paths to Tanzania run 150–200ms — a wired ethernet connection eliminates Wi-Fi jitter that makes longer international routes sound choppy.

  • 03

    Best time to call Dodoma

    Schedule Tanzania calls during Dodoma business hours — 09:00–17:00 Africa/Dar_es_Salaam — your contact will be at their desk in a quiet space rather than taking the call on the move.

Decision guide

Choosing the right service for calling Tanzania

When selecting an international calling service for Tanzania, four factors separate the durable providers from the noise. Look for a proven track record on each.

Coverage

Zone 2 routes are fragmented — confirm direct in-country termination to Dodoma, not regional hub routing.

Reliability

African routes degrade on cable outages — require redundant paths and a published failover RTO for Tanzania.

Customer support

Confirm coverage for Africa/Dar_es_Salaam hours — a Dodoma route issue at 09:00 needs a human response, not a next-day ticket.

Transparent pricing

Zone 2 landline and mobile rates can differ 5× — demand separate +255 landline and mobile rate sheets.

FAQ

Questions about calling Tanzania, answered.

Everything a business or traveller needs to know before dialling Tanzania (+255). Can't find an answer? Our team is one click away.

Q1.What is the country code for Tanzania?
Tanzania's international calling code is +255. Dial it immediately after your exit prefix and before the local subscriber number whenever calling from outside Tanzania.
Q2.How do I dial Tanzania from Europe?
From Europe dial 00 255, followed by the local Tanzania number (drop the leading 0). On a European mobile, + 255 works everywhere without needing to remember the exit code.
Q3.Can I use WhatsApp or Viber to call Tanzania?
Yes — WhatsApp and Viber both support free app-to-app voice calls to Tanzania over Wi-Fi or mobile data. To call a regular +255 landline or mobile, you will need a paid credit balance or subscription plan.
Q4.What is the + sign for when dialling Tanzania?
The + replaces your local international exit code. When you call Tanzania using +255, your carrier automatically substitutes the correct exit prefix (00 in Europe, 011 in North America, 0011 in Australia) before the call goes out.
Q5.Why won't my call to Tanzania connect?
Common causes include dialling the wrong exit code, keeping the leading 0, or missing digits in the subscriber number. Double-check the format: + 255 [area code without 0] [local number]. Also confirm your plan includes international dialling to Tanzania.
