SID codes are assigned by the national telecom regulator, a designated organization or, failing that, by IFAST if the national authority is unwilling or unable to perform this task or if the operator wants a range directly from IFAST (e.g. a mobile satellite operator).

Note that the information in table comes from a variety of sources and it cannot be assumed that it is all accurate. If you have any information to add to this list, or corrections to make, please contact the SID administrator.

Based on IFAST SID Assignment Guidelines, SID Codes can be in a number of states:

• Unassigned – The SID is not assigned to any entity (it is not safe to assume that SID codes not in this list are unassigned, due to the distributed nature of SID assignment and limited data available to IFAST).
• Pending – A carrier or other entity has expressed interest in a SID code, but the formal assignment process has not been initiated.
• Paid – A carrier has paid the assignment fee to IFAST but the assignment has not yet been publicly reviewed.
• Under Review – The SID assignment is in the two week IFAST review period.
• Assigned – The SID has been assigned by IFAST.
• Reserved – The SID has been reserved by the administrator for a specific reason.
• Grandfathered – The SID was in use prior to IFAST initiating management of a specific SID range.
• Being Grandfathered – The prior use of a SID has only recently been reported to IFAST.
• Conflict – The SID is believed to be in use, but it was not legitimately assigned.
• Conflict Reported – A conflict that has only recently been reported to IFAST.
• National Assignment – The SID has been assigned to a carrier by the national regulator or its designated assignment authority.
• National Assignment Reported – The national assignment has only recently been reported to IFAST.
• Returning – A carrier has requested that the SID be returned as it is no longer being used.
• Reclaiming – A SID is being reclaimed by IFAST due to non-payment of annual maintenance fees.
• Dormant – A SID has been reclaimed by IFAST, but will not be re-assigned for some time.

In the following table, bold is used to indicate SID codes for which information or status has changed within the last 6 months.

Light red indicates the SID usage represents a conflict and Light blue indicates an assignment by a national authority or by IFAST.
