• Twilio's PortIn API exposes per-number rejection_reason and rejection_reason_code fields when a carrier declines a number, plus not_portability_reason_code for numbers that cannot be ported. in context
• Twilio's PortIn API requires the target port-in date to be at least 7 days in the future for US ports and does not guarantee the date, which depends on the losing carrier. in context
• A Twilio PortIn request must reference at least one uploaded document of type Utility Bill. in context
