About Sao Tome and Principe Calling Code

Sao Tome and Principe's international dialing code is +239. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Sao Tome and Principe from another country. Sao Tome and Principe is located in Africa.

Sao Tome and Principe is known locally as São Tomé e Príncipe — Sao Tome is the capital. When saving an international contact, write the number in full international format with +239 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 +239 Calling Code Is Used

The country code +239 is assigned to Sao Tome and Principe, located in Middle Africa, with the capital Sao Tome. This code is part of the international telephony numbering plan and is used for all calls made to Sao Tome and Principe from outside the country.

When you see a phone number written as +239 ..., the +239 prefix tells your telephone network to route the call to Sao Tome and Principe'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 Sao Tome and Principe, in Middle 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 +239 followed directly by the area code and number.

Sao Tome and Principe Phone Number Formats

Phone numbers in Sao Tome and Principe 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.

📱 Number Structure

  • International format: +239 [area code] [subscriber number]
  • From abroad: exit code + +239 + local number (drop the trunk prefix 0)
  • Within Sao Tome and Principe: dial the local number directly

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 Sao Tome and Principe from abroad, always replace the leading trunk zero with the country code +239.

Time Zone in Sao Tome and Principe

Sao Tome and Principe is in the Africa/Sao_Tome 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 Sao Tome and Principe, the time difference matters: a good time to reach businesses in Sao Tome, 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 Sao Tome and Principe 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.
