FAQs
Is this service free?
Yes. The regulator’s My Numbers (Arqami) inquiry lists “Fees: none” and returns results instantly. (For SMS, CST states it coordinated a free mechanism with operators to let subscribers check lines registered to their IDs.)
Can I check without an active number?
Yes. On the inquiry page, set “Do you have a mobile number?” → No, and proceed with the mobile field is optional (“enter mobile… if available”).
Can visitors without an Iqama use this?
No. The service requires a Saudi National ID / Iqama (or a Commercial Register for businesses). Visitors without an Iqama are not eligible to use the inquiry.
Will corporate numbers appear under my Iqama?
Only numbers registered against your personal ID appear. Lines registered under a company’s Commercial Register (CR) will not show in your personal inquiry, so contact your employer/admin for those.
I recently ported my number. When will it show?
Once the port completes and the carrier records update, My Numbers reflects the change in real time (the service itself is instantaneous). If it doesn’t update after activation, check again later or contact your operator/CST.
