Most organizations only need one texting phone number. An administrator purchases it in CoolFocus after text messaging approval is complete and WayCool has connected your texting credentials. This article covers how to search for and purchase that number, then turn it on for reminders.
This is an administrator task. If you do not see Settings → Inbox Settings → Numbers, ask a system administrator.
See also Texting Compliance Requirements.
You can only use Add Number when both of these are true:
Text messaging approval for your organization is approved (compliance requirements have been met or texting is already active), and
WayCool has connected your organization’s texting credentials
Until then, Add Number stays disabled, and CoolFocus shows Texting approval required, with a link to open approval status.
Typical workflow steps:
Contact WayCool Support if Inbox texting is not yet on your subscription
Complete Texting Compliance Requirements under Settings → Inbox Settings → Compliance (brand details, legal pages, consent proof, message examples, precheck, submit for WayCool review, then carrier review)
Wait for approval and for WayCool to connect texting credentials
Purchase your number (steps below)
Turn on SMS routing so the number can send appointment reminders (steps below)
Open Settings → Inbox Settings → Numbers (page title Phone Numbers)
Select Add Number
In the Add Phone Number window:
Choose Number type: Local or Toll-Free
For a Local number, enter a 3-digit Area code (for example, 612). For Toll-Free, area code is optional — leave it blank to search all toll-free options
Select Search
Review the list of available numbers. Each row shows the number, whether SMS (text) and Voice are available, and the monthly price
Click Select on the number you want
Confirm the monthly cost, then select Confirm Purchase
CoolFocus purchases the number on your messaging account and configures it to receive SMS. You should see a success message, and the number appears on your Phone Numbers list.
The new number is not automatically set as the reminder sender. Turn it onusing the steps below:
On Settings → Inbox Settings → Numbers, find the number you just purchased
Under SMS routing, turn the switch on so the status says Enabled for reminders (this is the same as Use for Reminders on the number’s Configure page)

Optional: enter a Friendly name (for example, “Main Office”) so staff can tell numbers apart
Optional: open Configure on the number if you want a Campaign label for local attribution reporting (for example, radio ad vs website). That label is only for your reporting — it is not your carrier A2P campaign registration
Most centers leave a single number with Use for Reminders turned on. If you buy more than one number later, only the ones you enable for reminders will be used for appointment reminder text messages.

You do not need a separate number for each staff member.
CoolFocus can keep Client, Donor, and Volunteer texting streams separate in Inbox. That is about how conversations are grouped, not a second purchase step for most centers.
Most organizations use one purchased number for everyday client texting
You do not need a different number for every person — one number is enough for normal use
Campaign label (if you use one) is only for local attribution reporting. It is not the same as Inbox Domain and not your carrier A2P campaign registration
See Inbox Domains: Client, Donor, and Volunteer for how domains work in Inbox.
Add Number is disabled — Finish text messaging approval under Settings → Phone → Compliance, or wait for WayCool to connect credentials after approval
Search finds no numbers — Try another area code or Toll-Free
Purchase fails — Note the error message and contact WayCool Support. Do not buy the same number twice from outside CoolFocus
Number appears but reminders still will not send — Confirm SMS routing / Use for Reminders is on for that number, and that clients are marked OK to text. See Reminders, Notifications, and Intake Messages
