About Guinea-Bissau Calling Code

Guinea-Bissau's international dialing code is +245. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Guinea-Bissau from another country. Guinea-Bissau is located in Africa.

Guinea-Bissau is known locally as Guiné-Bissau — Bissau is the capital. When saving an international contact, write the number in full international format with +245 so it works from any country.

Country calling codes (also known as ISD codes or dialing codes) are telephone numbering plan prefixes defined by ITU-T standards E.123 and E.164. Each country is assigned one or more unique prefixes to facilitate international direct dialing.

Where the +245 Calling Code Is Used

The country code +245 is assigned to Guinea-Bissau, located in Western Africa, with the capital Bissau. This code is part of the international telephony numbering plan and is used for all calls made to Guinea-Bissau from outside the country.

When you see a phone number written as +245 ..., the +245 prefix tells your telephone network to route the call to Guinea-Bissau's national telephone network. After the country code, you dial the local area code (dropping any leading 0) and the subscriber number. The same format applies whether you are calling a landline or a mobile phone.

Country codes are allocated by the International Telecommunication Union (ITU-T Recommendation E.164) and are grouped by geographic region. Calling codes starting with 2 are generally assigned to the region around Guinea-Bissau, in Western Africa. When a phone number is stored internationally, the leading zeros of the domestic area code are omitted after the country code — this is why you will often see numbers written as +245 followed directly by the area code and number.

Guinea-Bissau Phone Number Formats

Phone numbers in Guinea-Bissau follow the ITU E.164 international format: country code + area code + subscriber number. Below is the general structure used for both landlines and mobile numbers.

Most countries use a closed or open telephone numbering plan. In an open plan, the length of local numbers varies and the trunk prefix (usually 0) is dropped when dialing internationally. In a closed plan, all national numbers have a fixed length regardless of area. When dialing Guinea-Bissau from abroad, always replace the leading trunk zero with the country code +245.

Time Zone in Guinea-Bissau

Guinea-Bissau is in the Africa/Bissau time zone, which is UTC+00:00 relative to Coordinated Universal Time (UTC). If you are calling from a different time zone, remember to account for the time difference when scheduling your international call.

When planning a call to Guinea-Bissau, the time difference matters: a good time to reach businesses in Bissau, the capital, during their working hours may be early morning or late evening in your own time zone. Many international callers use the UTC offset as a quick reference to avoid calling in the middle of the night.

Some countries observe daylight saving time (DST), which shifts the local clock by one hour during summer months. If Guinea-Bissau uses DST, the effective offset changes twice a year — check the current UTC offset before dialing if your call is time-sensitive. For most purposes, however, the standard offset shown above is sufficient.
