Guinea-Bissau numbering plan & how to dial
Guinea-Bissau uses a closed numbering plan under country code +245: subscribers are reached with a single 7-digit number after the country code, with no separate area code to dial.
Mobile coverage in Guinea-Bissau comes from 2 major networks — MTN Guinea-Bissau, Orange Guinea-Bissau — with internet penetration at 34%. VoIP is permitted and regulated by ARN (Autoridade Reguladora Nacional das Comunicações). Language (Portuguese) and currency (XOF) both matter here for IVR, SMS, and scheduling support around local business hours.
Across African markets, mobile-first numbering dominates and Tier-1 interconnects are the key to consistent call delivery and CLI presentation.
Skipping the exit code
From the US you must dial 011 before the +245 country code to reach Guinea-Bissau.
Adding an area code that doesn't exist
Don't insert an area code for Guinea-Bissau: it's a closed plan, so +245 plus the 7-digit number is the whole address.
Ignoring the time difference
Before dialing Guinea-Bissau, check the local clock — it runs on UTC+0, and off-hours calls tend to go unanswered.
