Deep breath. Here's the answer.

A tourist visa is required for US citizens visiting Tanzania. Tanzania's official immigration visa guidelines (read 13 Oct 2026) list two ways to get it: apply online before you travel, which the guidelines recommend, or apply on arrival. US citizens are listed as eligible for a visa on arrival. For tourism, US citizens must get a Multiple Entry Visa, even for a single entry. If you apply online, wait for the visa grant notice before you start your journey; a grant does not guarantee entry. The guidelines list the tourist Multiple Entry Visa fee for US citizens as USD 100. The visa can be valid for up to 12 months, but each visit can last up to 3 months (90 days) — it does not allow a 12-month stay. Confirm the fee and dates on the official source before you apply.

Key facts

For United States passport holders, tourism or short business trips.

You may need a visa if…

• A tourist visa is explicitly required for U.S. citizens.
• Passport must be valid at entry and for at least 6 months beyond your arrival date in Tanzania.
• Only passports with M or F sex markers are accepted; verify on the official source if this applies to you.
• Mainland Tanzania: the Ministry of Health notice ‘YELLOW FEVER ENTRY REQUIREMENTS IN TANZANIA MAINLAND’, dated 16 November 2023 (read 14 Oct 2026), says a yellow fever vaccination certificate is required for travellers arriving from a yellow-fever-endemic country or transiting through one for 12 hours or more. The notice says travellers with neither route condition are not subject to this requirement. Current Tanzania Port Health requirements have not been confirmed — check your full route with Port Health before travel. The notice includes medical and age exemptions, but whether one applies to you must be confirmed with Port Health and your clinician. This mainland notice does not establish Zanzibar requirements.
• Currency: Tanzania's Anti-Money Laundering (Cross-Border Declaration of Currency and Bearer Negotiable Instruments) Regulations, 2016 (G.N. 268 of 2016; mainland Tanzania; read 14 Oct 2026) require declaring to Customs, on entry or exit, currency and bearer negotiable instruments totalling USD 10,000 or more (or the equivalent). The US State Department Tanzania page (read 14 Oct 2026) instead describes USD 10,000 as an entry/exit maximum. These sources conflict. We have not confirmed whether the 2016 regulations have since been amended, or what applies in Zanzibar. Confirm with Tanzania Customs before carrying USD 10,000 or more.
• NIC says its inbound travel insurance is mandatory for foreign nationals entering mainland Tanzania by land, sea or air; its FAQ (read 13 Oct 2026) excludes residents of EAC/SADC partner states. Show the digital or printed certificate on arrival. NIC's FAQ says to buy it before arrival at entry points, and also says it can be bought online or on arrival (cash payment on arrival). Arrange it before you travel and confirm details with NIC.
• Zanzibar: the US State Department Tanzania page (read 13 Oct 2026) says visitors to Zanzibar must buy specific local insurance, even if they already have international cover, through the government portal or on arrival. Zanzibar Insurance Corporation's FAQ (read 13 Oct 2026) says proof of international insurance is not accepted and the policy must be issued by ZIC. UK government guidance for British passport holders (not US guidance) describes insurance according to the first port of entry and purchase history, naming NIC for mainland and ZIC for Zanzibar; consult that source for its conditions. We have not confirmed whether a mainland NIC policy covers a later Zanzibar visit for US travellers — check before you travel.
• Use the health portal for your destination: Zanzibar (healthtravelznz.mohz.go.tz/traveller/) versus mainland Tanzania (afyamsafiri.moh.go.tz). Both actual landing pages require a separate form for each child; a parent/guardian may assist. Their detailed form fields and submission flow were not tested.
• Zanzibar's Health Ministry portal requires the online Public Health Surveillance Form within 24 hours before arrival. Mainland AfyaMsafiri instructs travellers arriving from or transiting Ebola-affected countries to complete its separate form within 24 hours before or on arrival. Government travel-advice summaries describe a broader all-traveller obligation, so confirm the mainland rule for your full route; do not assume the visa application replaces the health form.

• ✓Visiting Zanzibar or both mainland and Zanzibar: check which inbound insurance your route needs with NIC, ZIC or Tanzania immigration before travel.
• ✓Zanzibar's Health Ministry portal requires the online Public Health Surveillance Form within 24 hours before arrival.
