63058: Business is restricted from messaging users in this country

This error occurs when you attempt to send a WhatsApp message to a recipient in a country or region where the WhatsApp Business Platform is not supported, or where Twilio blocks delivery due to sanctions or regulatory restrictions.

• The To number is in a country or region where the WhatsApp Business Platform isn't supported (for example, Cuba, Iran, North Korea, Syria, and the Crimea/Donetsk/Luhansk regions).
• Twilio blocks message delivery to recipients in certain countries and regions for compliance reasons (for WhatsApp and RCS, this includes all To numbers beginning with +98 for Iran. Twilio also stopped delivering voice, messaging, and email traffic to recipients in Iran, Syria and Cuba).
• Your business or use case falls under WhatsApp restrictions that prohibit usage in specific countries, preventing WhatsApp messaging for those markets.

• Confirm that the recipient's To country or region is supported by the WhatsApp Business Platform and isn't subject to Twilio delivery blocks. If it's unsupported or blocked, don't send WhatsApp messages to that number.
• If your business is in a forbidden country or otherwise restricted by WhatsApp policy, evaluate compliant alternatives for that market (for example, select another supported channel where permissible and aligned with local rules).
