The numbering plan of São Tomé and Príncipe: formats, lengths, the regular expression for each line type and the prefix blocks allocated to each carrier, as ITU publishes it. A pattern says what a number looks like and where it was allocated; whether it is in service, and who serves it today, is a different question (below).

Questions developers ask

How many digits does a phone number in São Tomé and Príncipe have?
Mobile numbers have 7 national digits. Fixed line numbers have 7 national digits. That is the national number, without the country code +239.
What is the country code for São Tomé and Príncipe?

Which prefixes are mobile numbers in São Tomé and Príncipe?
Mobile numbers start with 90, 98 or 99 in national form; the mobile regular expression on this page gives the exact ranges (example: 981 2345). The carrier table shows which prefix blocks were allocated to which operator.
Can a mobile number in São Tomé and Príncipe be ported to another carrier?
Not on record. The plan data this page is built from does not list mobile number portability for São Tomé and Príncipe, so the carrier a prefix was allocated to is likely, not certainly, the carrier serving the number. Only a live carrier lookup (an HLR or MNP query) confirms it.
