I'm sorry to hear that you're experiencing issues with purchasing phone numbers. It's possible that there might be a temporary limitation or a change in the availability of certain area codes. Availability can fluctuate based on inventory and regulations. However, without seeing the specific error message from the screenshot, I can't provide a precise answer.
If you could describe the error message or provide the text, I might be able to offer more detailed assistance. In the meantime, please ensure that you are following the current guidelines for purchasing phone numbers and that there haven't been any recent changes to the API or its documentation that might affect the process.
If the issue persists, it might be best to reach out to support for a more in-depth investigation.
