The problem this solves
An existing number is familiar to customers but may be less organized. A dedicated number provides better separation between business and other uses.
Working cleanly
Check who should send messages to the number, who handles them and whether it is important for customers to recognize the number.
What to check
Check customer recognition, documentation, team access and the ability to separate business messages from private use.
Next step
After choosing a number, connect it to email, a webhook or a system as needed.
