What is the country code for Guinea-Bissau?
Guinea-Bissau's country code, +245, covers a small West African nation on the Atlantic coast, bordered by Senegal and Guinea, and including the Bijagós Archipelago just offshore. Its telephone numbering plan is refreshingly simple by international standards: rather than juggling a mix of geographic area codes across different regions, Guinea-Bissau uses a flat 9-digit local number format for both landlines and mobiles, with the network or region identified by the leading digits of the number itself rather than a separately-dialed area code.
Landline numbers largely route through the 44-prefix range operated by Guiné Telecom, covering Bissau and other municipalities including Bafatá and Gabú, while mobile numbers are cleanly divided into blocks by carrier — 950–959 for Orange Bissau, 960–969 for Spacetel Guiné-Bissau, and 977 for Guinétel.
程式碼 +245 被分配給 Guinea-Bissau 由 ITU 根據 E.164 計劃制定。這 “+” 意思是「撥打您當地的國際退出代碼」；在行動裝置上，按住 0 來輸入它。

How to call Guinea-Bissau from anywhere
Calling Guinea-Bissau from abroad: +245 XXX XXXX — a 9-digit local number following the country code.
Calling within Guinea-Bissau: dial the full 9-digit number directly — there is no domestic trunk prefix to add or drop.
Calling out from Guinea-Bissau: dial 00 + country code + local number for international destinations.
Full example: +245 XXX XXXX — a flat 9-digit number, no domestic trunk prefix to drop.
Guinea-Bissau phone number format explained
Guinea-Bissau phone numbers follow a flat structure: +245 XXX XXXX — 9 digits total following the country code, with no separate area code. Country code 245; landline prefix primarily in the 44 range, covering Bissau and other municipalities via Guiné Telecom; mobile prefixes 950–959 (Orange Bissau), 960–969 (Spacetel Guiné-Bissau), 977 (Guinétel).
Unlike many countries that require a leading 0 for domestic calls (dropped internationally), Guinea-Bissau's numbering plan uses the same 9-digit number for both domestic and international dialing, once the +245 country code is added for international calls.

Guinea-Bissau mobile network prefixes
The prefix after +245 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.

Guinea-Bissau time zone
Guinea-Bissau sits in Greenwich Mean Time (GMT), UTC+0, year-round.
Guinea-Bissau does not observe daylight saving time — the UTC+0 offset holds constant all year, aligning it directly with the UK during UK winter months and with several other West African coastal nations like Ghana and Senegal. Once you've confirmed the offset against your own city, it stays correct indefinitely, since Guinea-Bissau's side of the calculation never changes.
Why this matters for business: if you're coordinating call center hours, IVR schedules, or SLA windows against Guinea-Bissau, the only variable to track is whether your own city shifts its clocks for DST — Guinea-Bissau itself is a fixed, reliable year-round reference point.

Common mistakes when calling Guinea-Bissau
幾乎每次失敗的國際電話都是格式問題，而不是網路問題。
Adding an unnecessary trunk prefix
Unlike many countries, Guinea-Bissau's 9-digit numbers don't use a leading 0 domestically that needs to be dropped internationally — the same 9 digits apply either way, following the +245 country code for international calls.
Assuming Portuguese fluency covers the whole customer base
Upper Guinea Creole (Kriyol) is the true day-to-day lingua franca for most of the population — customer-facing services built only around formal Portuguese may miss real customer signal.
Confusing the West African CFA franc with other CFA currencies
Guinea-Bissau uses the West African CFA franc (XOF), which is a separate currency union from the Central African CFA franc (XAF) used by some other francophone African nations.
Assuming uniform coverage nationwide
Coverage is strongest around Bissau, with more limited signal in rural interior regions and the Bijagós Archipelago's outer islands.
Tips to reduce the cost of calling Guinea-Bissau
Skip the trunk-prefix lookup entirely
Guinea-Bissau's 9-digit numbers are dialed the same way domestically and internationally (once +245 is added) — no leading 0 to add or drop.
Identify the carrier straight from the prefix
950–959 is Orange Bissau, 960–969 is Spacetel Guiné-Bissau, and 977 is Guinétel — no need to cross-check a regional area-code table for mobile numbers.
Route calls through VoIP or an MCM virtual number rather than paying carrier international rates into +245.
Plan for Kriyol-aware support where it matters
a support line built only around formal Portuguese may not connect as naturally with everyday callers as one with Kriyol fluency or cultural familiarity.
Why businesses get a Guinea-Bissau virtual number
Guinea-Bissau occupies an unusual linguistic position in West Africa: it's one of the very few Portuguese-speaking nations on the African mainland (alongside Angola and Mozambique, both in different regions), a legacy of Portuguese colonial rule. But Portuguese is spoken fluently as a first language by only a modest share of the population — the language that actually crosses ethnic and social lines in daily life, markets, and even much of government interaction is Upper Guinea Creole (Kriyol), a Portuguese-based creole language with its own distinct grammar and vocabulary.
For businesses considering a Guinea-Bissau virtual number, this linguistic reality matters directly: customer support built purely around formal Portuguese may not connect as naturally with everyday callers as a team with Kriyol fluency or at least cultural familiarity with it. It's also a reminder that "Portuguese-speaking Africa" isn't linguistically uniform — Guinea-Bissau's Kriyol-first daily communication culture is genuinely distinct from, say, Mozambique's more Portuguese-dominant urban centers.
