Area code information

Sao Tome area code is 12, with 5-digit subscriber numbers. Numbering format for Principe (area code or subscriber numbers) if any, is unknown.

1 August 2002 - Sao Tome national renumbering

The digit '2' was prepended to 5-digit Sao Tome subscriber numbers to form new 6-digit subscriber numbers effective 1 August 2002.

Domestic dialling now requires the 6-digit subscriber number. For example, subscriber number 23456 became 223456.

The area code '12' which had been used for all calls into Sao Tome was eliminated. The new 6-digit subscriber number became a national number. Thus, the international format for the above example changed from +239 12 23456 to +239 223456.

As of 2 April 2002, GSM mobile numbering is available in Sao Tome in the format +239 90 xxxx.
