1. Select the exact service
Choose Luup before selecting a country. Availability for another app does not imply that the same number is suitable for Luup.
About Luup SMS verification
NumFlow groups current countries, line references, and platform prices by target service. Select Luup first, then choose from the options currently shown for the account flow you are completing.
The assigned number and received code apply to the effective window of that order. Luup may restrict virtual or temporary numbers, so acceptance is determined by the target service rather than guaranteed by NumFlow.
How the Luup verification flow works
2. Compare current options
Review the available country, line reference, and platform price shown at the time of the order.
3. Track one order
Use the assigned number within the returned window and keep checking that same order until a code arrives or the order reaches its final state.
Luup verification FAQ
Can NumFlow guarantee a Luup verification code?
No. Luup controls whether it sends a code and accepts a particular number. NumFlow shows current availability and the resulting order status.
Which country should I choose for Luup?
Choose a country that fits the target account flow and is currently available. Compare the displayed line reference and platform price before ordering.
What if the Luup code does not arrive?
Keep checking the same active order until its returned expiry. If the order becomes cancellable or expires without a code, follow the status shown before retrying.
