Virtual number for Signal verification

What Signal numbers do in practice

26.2M lines can take a Signal code at this moment, spread over 110 countries, and the cheapest of them opens at $0.07 on a United Kingdom line. Where a country sits in that spread is not arbitrary — it follows what the local carriers charge and how reliably they hand the message over, which is why the grid above prints those two side by side rather than ranking on cost alone.

Cost is the least interesting difference between those 110 countries. Carriers return ranges to circulation at their own pace, so the idle counts drift across the day; what you see was measured when the page loaded, not cached overnight. And since the balance only moves once a code lands, a country that turns out not to answer costs you the wait and leaves the money where it was.

At volume the same catalogue reads over the API: one key, a bearer header, and Signal tariffs for any country returned as JSON. There is no separate wholesale sheet — the figures are the ones on this page — which is what lets the same endpoint serve a reseller and someone automating their own registrations without either being a special case.
