90033: Broadcast recipient's 'to' is too long

The recipient to value in your Notify broadcast request is longer than the maximum length allowed for the selected channel. Twilio rejects the request when a destination address does not match the expected format or exceeds channel limits.

• You sent a phone number, identity, or device address that is longer than the channel supports.
• The to value includes extra characters such as spaces, formatting symbols, or concatenated data that make the address invalid.
• You used the wrong destination type for the channel, such as sending a non-phone-number value for an sms or mms notification.
• Your application passed an unvalidated user-supplied value into the recipient list.

• Validate each recipient address before you send the broadcast.
• For sms and mms, send the destination as a valid phone number in E.164 format.
• Make sure the to value matches the channel you selected and remove any unsupported prefixes, labels, or appended metadata.
• Review your application logic for string concatenation or serialization issues that can make the destination value too long.
• If you are sending to identities or bindings, confirm that the stored address or identity value is within the limits required by your Notify integration.
