Handling number reassignment
Separate a formatting-valid number from a current recipient match. Number validation, carrier lookup, and reassignment checks answer different questions.
Putting the guide into practice
Document when the number was collected, its last reliable association with the recipient, and any applicable reassignment-check result. Suppress uncertain records pending review.
- Collection date
- Recipient association
- Check result
- Suppression decision
Limits and review decisions
A successful delivery does not prove the intended supporter received the message. Never infer identity solely from a phone number's historical entry.
