Blocked Handles

Block handles — phone numbers, email addresses, SMS short codes, or sender IDs. Inbound messages from a blocked handle are dropped before they reach your webhooks, and direct sends to a blocked handle are rejected with 403 (error code 2026). Group sends that include unblocked members are not restricted.
