SIP Trunk Saudi Arabia — +966 Termination & DID Numbers
Saudi Arabia is the Gulf's largest voice market by population, and traffic spikes around Ramadan and the Hajj season. CST regulates numbering and services closely, so termination is widely available but local numbers depend on your licensing position.
Overview
Routing calls to Saudi Arabia
Calling windows matter: Saudi Arabia runs on Riyadh time, and we route +966 calls for Riyadh, Jeddah and Mecca, Medina and Dammam across several carriers so a peak-hour congestion event on one network does not take your campaign down.
Numbering in Saudi Arabia is managed by CST. We terminate to geographic, mobile and toll-free ranges and price each one separately on the rate sheet. Inside the country, numbers are dialled with a 0 trunk prefix. Strip it before you send the call, and send 966 followed by the national number.
Outbound calls to Saudi Arabia work on a standard account. Inbound DIDs are restricted, and options depend on licensing and current stock, so our team confirms availability before taking an order.
