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.
Carriers & language
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.
Africa context
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.

FAQ
A recognisable +245 number tends to get answered more often than an unfamiliar international one — that's the main reason to present local caller ID in Guinea-Bissau. Unknown foreign numbers are frequently screened or ignored, which can quietly suppress answer rates on outbound sales and support calls.
Across African markets, mobile-first numbering dominates and Tier-1 interconnects are the key to consistent call delivery and CLI presentation. In Guinea-Bissau specifically, that's overseen by ARN (Autoridade Reguladora Nacional das Comunicações), which sets the compliance bar Twiching's routes are built to meet.
No license restriction beyond standard regulation — ARN (Autoridade Reguladora Nacional das Comunicações) permits VoIP in Guinea-Bissau for compliant operators. That keeps setup straightforward for a Twiching customer looking to call or text into the country.
