Numbering Plan Update 2026-04-22 - Domestic only numbers

The Domestic-Only Number Trap

Every country has phone numbers that can't be dialled from abroad. Almost no regulator publishes which ones.

Take Poland. You can download the regulator's numbering plan as XML or CSV. You get the operator name and the last modification date. That's it. No flag for which mobile ranges are reachable internationally and which aren't. Carriers that care have built their own internal documents to fill the gap. It's not just Poland. This is the norm.

What's a domestic-only number?

Short codes. Premium rate ranges a regulator has restricted from international origination. Operator test ranges. Local government numbers only usable from inside the country. Specific allocations the regulator has marked for domestic use only. The regulator knows. The operator knows. The published plan, overwhelmingly, does not say.

When a transit carrier routes an international call, that invisibility costs money. The call either fails silently (burning interconnect capacity on traffic that was never going to complete) or it lands on whatever the operator does with unreachable numbers, which is sometimes a fraud trap. Artificially Inflated Traffic schemes love a deallocated, restricted, or shouldn't-have-been-dialled range that still generates a billing event.

The same problem, different face

Earlier this month we wrote about Origin Based Rating, and the fundamental problem that no one in the call chain agrees on a single source of numbering truth. This is the same problem with a different face.

OBR punishes you for routing a call from the "wrong" origin. The absence of a domestic-accessibility flag punishes you for routing a call to the "wrong" destination. Both share the same cause: the published reference doesn't contain enough information for a transit carrier to demonstrate due diligence.

A single column that changes the arithmetic

There's a proposal gaining traction in the international voice industry to add a new column to the ITU's E.129 numbering plan template: Domestic Accessibility Only. A simple flag: yes means the range is not intended to be reachable from abroad. Most rows stay blank. The flagged ones are the ones a carrier actually needs to know about.

At least one operator has already solved it for their own network. . The question is whether every other operator has to build it independently, or whether the regulator, who controls the allocation in the first place, publishes it once.

The regulator is the right owner here. They decide which ranges go where, and which are intended for internal use only. Every other entity in the call chain is guessing.

Speed matters

The proposal needs ITU endorsement and a nudge to each national regulator. The ITU itself can't compel member states to submit numbering updates. That's a structural limitation of the treaty, not a bureaucratic one, so the path to adoption is slow unless the industry maintains pressure.

The counter-argument we keep hearing from regulators is that publishing what's domestically-restricted tips off fraudsters. It doesn't. Fraudsters generate and spoof numbers regardless of what regulators publish; what they don't do is build international fraud detection. Carriers do, and right now they're building it blindfolded. Transparency helps the defenders far more than the attackers.

What we're doing

We flag what we can at e164.com. Where a regulator quietly notes a range is domestic-only, where an operator tells us, where our own testing confirms a range doesn't complete internationally, we mark it. We haven't yet exposed this to e164 subscribers, but it's coming. That's a workaround while the industry moves towards a standardised field that everyone can point to.

If your fraud team, your routing team, or your billing team has spotted a range that shouldn't be reachable from abroad (and is), we want to know. Email support@e164.com. You don't need to be a paying subscriber. Your anomaly is someone else's exposure.

A standardised column won't fix wholesale voice on its own. But it's one of the cheapest, most tractable wins available, and the industry is lining up behind it. Now we need the regulators.
