NMIBTZTZ11-character variant (head office):
NMIBTZTZXXX| Bank code | Country | Location |
|---|---|---|
| NMIB | TZ | TZ |
| NMB | TZ (Tanzania) | Dar es Salaam |
An 11-character variant like NMIBTZTZXXX also indicates the head office — the trailing 'XXX' is the default. Codes ending in different sequences (e.g. 'NMIBTZTZ001') refer to specific branches.
National Microfinance Bank (NMB) was established in 1997 from the restructuring of the Tanzanian Post Office Bank and has grown into one of the country's largest commercial banks by both deposits and branch network. NMB is listed on the Dar es Salaam Stock Exchange and operates more than 230 branches across Tanzania, making it the bank with the widest geographic coverage in the country. The Netherlands-based development financier FMO and Rabobank have historically held significant stakes. For diaspora senders supporting family members in upcountry Tanzania, NMB's extensive branch network means the destination account is often physically reachable. SWIFT code NMIBTZTZ identifies the Dar es Salaam head office; the long form is NMIBTZTZXXX.

SWIFT and BIC are two names for the same identifier: an 8 or 11-character code standardised by ISO 9362 that identifies a bank in the SWIFT payment network. For a wire to NMB, your sending bank needs this code (NMIBTZTZ) to route the payment message through correspondent banks to National Microfinance Bank in Dar es Salaam.
An IBAN, by contrast, identifies a specific bank account — not the institution. IBANs are mandatory in the European Economic Area, the UK, most of the Middle East, and several African countries (but Tanzania does not use IBANs universally). For most wires to Tanzania, you will supply SWIFT code NMIBTZTZ + the recipient's account number, not an IBAN.
UK sort codes (6 digits) and US routing numbers (9 digits) are domestic-only equivalents — they do not work for international wires. If a US-based sender wants to wire to NMB, they need the SWIFT code, not the US routing number of the correspondent bank (although their bank may use the routing number internally to route their side of the wire).
One final technical detail on the 11-character form: the last three characters identify a specific branch. When they read 'XXX' (as in NMIBTZTZXXX), they conventionally designate the head office itself. Most international wires use either the 8-character form or the 11-character form with XXX; unless your recipient explicitly tells you otherwise, that is the right choice.
National Microfinance Bank's SWIFT/BIC code is NMIBTZTZ. This 8-character code identifies the bank's Dar es Salaam head office for international wire transfers.
Yes. SWIFT (Society for Worldwide Interbank Financial Telecommunication) and BIC (Business Identifier Code) are two names for the same 8 or 11-character identifier standardised by ISO 9362. You will see NMB's code referenced under either name on different financial platforms.
Yes. For an international wire to reach your NMB account, the sender needs SWIFT code NMIBTZTZ AND your account number. Some sending banks also request the recipient bank's full address (NMB House, 4 Aly Hassan Mwinyi Road, Dar es Salaam).
Typically 1 to 5 business days. The timing depends on the intermediary (correspondent) banks between the sending bank and NMB. Wires from major global banks (HSBC, Barclays, JPMorgan, Citi) usually clear fastest.
For smaller amounts to Tanzania, operators such as Wise, LemFi, Sendwave, and TapTap Send typically offer a rate closer to mid-market and lower fees than a classic SWIFT bank wire. See our Tanzania inbound corridor comparison for side-by-side pricing.
