If you are exploring International Premium Rate Numbers (IPRN) as a revenue stream for your carrier or MVNO, you will quickly encounter two distinct categories: standard IPRN numbers and ATX (Access Tandem Exchange) numbers. Both generate per-minute revenue, but they differ significantly in rate, access requirements, and how they fit into your routing strategy.
What Are Standard IPRN Numbers?
Standard IPRN numbers are premium rate telephone numbers tied to specific country codes or special number ranges. They charge callers a premium per-minute rate, and a portion of that charge flows back through the carrier chain to the terminating network. Standard IPRN is accessible to a broad range of operators, including smaller carriers and MVNOs with basic SIP infrastructure.
Typical characteristics:
- Per-minute rates that are several times higher than standard international termination.
- Available in dozens of countries across Europe, Africa, Asia-Pacific, and the Americas.
- Accessible to carriers with standard wholesale interconnection agreements.
- Daily or weekly payouts with transparent rate cards.
What Are ATX Numbers?
ATX stands for Access Tandem Exchange. ATX numbers are a specialised premium rate category used within wholesale voice interconnection — they are not dialled directly by consumers but are instead used as termination destinations within carrier-to-carrier traffic exchanges.
Key characteristics:
- Significantly higher per-minute rates than standard IPRN — often the highest in the entire premium rate ecosystem.
- Available exclusively to licensed telecom operators — not available to end-users, resellers, or uncertified businesses.
- Designed for wholesale voice interconnection, meaning they fit directly into carrier routing tables.
- Require a direct interconnection agreement with the ATX provider (Orange Carrier handles this for qualified operators).
Side-by-Side Comparison
| Feature | Standard IPRN | ATX Numbers |
|---|---|---|
| Per-minute rate | High | Very high (highest in IPRN) |
| Access requirement | Standard carrier agreement | Licensed telecom operator only |
| Traffic type | Consumer + wholesale | Wholesale interconnection only |
| Country availability | Broad global coverage | Select markets |
| Best for | All carriers and MVNOs | Large carriers with high-volume wholesale traffic |
Which Should You Choose?
For most operators getting started with IPRN, standard IPRN routes are the right entry point. They offer immediate revenue, broad country coverage, and minimal setup complexity.
If your operation handles high volumes of wholesale voice interconnection traffic and you hold a telecom licence, ATX numbers should be part of your IPRN portfolio. The higher per-minute rates justify the additional qualification steps, and the revenue uplift on large volumes is substantial.
Many Orange Carrier partners start with standard IPRN and add ATX routes as their traffic volumes grow. Our account team manages this progression and ensures you are always on the best rates available for your traffic profile.
