Understanding Saudi Phone Prefixes
Every mobile number in Saudi Arabia begins with 05 domestically, or +966 5 in international format (you drop the leading zero when adding the country code). The digit that follows identifies the original network operator — for example numbers historically starting 050 and 055 belonged to STC, 056 and 054 to Mobily, and 059 and 058 to Zain. Because of mobile number portability, a prefix today only tells you the original carrier, not necessarily the current one, since subscribers can keep their number when switching providers.
Landline numbers use area codes instead: 011 for Riyadh, 012 for Makkah and Jeddah, 013 for the Eastern Province, 014 for Madinah and the north-west, 016 for Qassim and the centre, and 017 for the south. This lookup tool lets you enter any Saudi number and instantly see the network or region it is associated with.
Why it is useful
Identifying a prefix helps you recognise the likely operator before calling, estimate roaming or call costs, spot mistyped numbers, and verify that a number is formatted correctly for SMS gateways or business systems. For international callers, always use the +966 format and omit the first 0 of the local number.
