^[+]?[0-9 ()\-]{6,}$A Guinea-Bissau phone number is 9 digits under the country code +245. A small West African nation on the Atlantic coast between Senegal and Guinea, Guinea-Bissau is a former Portuguese colony and remains the only Portuguese-speaking country in an otherwise largely French-speaking part of West Africa, a legacy that shapes its official language even though most residents speak Guinea-Bissau Creole day to day.
How this validator works
Enter the number in national form (0955012345) or full international form (+245955012345); this tool checks the 9-digit length and leading-digit pattern against Guinea-Bissau’s real numbering plan using Google’s libphonenumber, entirely in your browser. The similar country names in this corner of West Africa make code mix-ups common — Guinea-Bissau’s +245 is entirely separate from Guinea’s +224, despite the shared “Guinea” name and neighboring borders.
What a pass doesn’t tell you
A pass confirms the digits form a real Guinea-Bissau number shape — it doesn’t confirm the SIM is active or the landline connected, a separate carrier-side question this tool doesn’t try to answer.
Scope: useful for catching a wrong-code mix-up with a similarly-named neighbor before a Guinea-Bissau number reaches a form — not a substitute for a real lookup service.

phone number FAQ
Is Guinea-Bissau the same as Guinea or Equatorial Guinea?
No — all three are separate West and Central African countries that happen to share a root name from the historical 'Guinea' coastal region. Guinea-Bissau is a former Portuguese colony with its own +245 country code, distinct from Guinea's +224 and Equatorial Guinea's +240.
What language is used officially in Guinea-Bissau?
Portuguese, inherited from colonial administration and still the sole official language, even though Guinea-Bissau Creole is more widely spoken day-to-day — a linguistic legacy that sets it apart from its French-speaking neighbors Senegal and Guinea.
Does a valid check confirm a Guinea-Bissau number is currently active?
No. It only confirms the 9 digits match a real Guinea-Bissau numbering pattern — not that the SIM is active, which needs a carrier-side lookup this free tool doesn't perform.
