Every organization in Amplifi sends from a dedicated phone number. This number appears as the “From” number on every campaign, poll, and conversation reply your organization sends. Having a consistent sending number helps your contacts recognize where messages are coming from and keeps your outbound traffic scoped to your organization.

​
Your organization’s sending number

When your account is set up, Amplifi provisions a dedicated Twilio phone number for your organization. All outbound SMS and MMS traffic—campaigns, poll messages, and inbox replies—goes through this number. Inbound replies from your contacts come back to the same number, which is how they appear in your Conversations inbox. One sending number per organization is the standard setup. Your number is tied to your organization and is not shared with other organizations on the platform.

​
How your number is assigned

Your sending number is chosen during the onboarding process, before you can start importing contacts or sending campaigns.
1

Enter your preferred area code

During onboarding, you are prompted to enter the area code you want your texts to come from. Choose an area code that makes sense for your audience—local numbers often see better engagement.
2

Select from available numbers

Amplifi searches for available numbers in that area code and displays the options. Pick the number you want.
3

Confirm your selection

Once you confirm, Amplifi provisions the number and attaches it to your organization. Your sending number is now active.
You cannot import contacts or send campaigns until your sending number has been provisioned. This step is required before you can move forward in onboarding.

​
Viewing your sending number

You can see your organization’s current sending number in Settings.
1

Open Settings

Click Settings in the left sidebar.
2

Go to the General tab

Your assigned phone number is displayed in the General settings area.

​
If you need a different number

If you want to change your sending number or need help with your current number, contact Amplifi support. Number changes are not self-serve—the support team will work with you to release your current number and provision a new one.
Changing your sending number affects all future outbound messages from your organization. Any contacts who have saved or recognized your old number will see a new sender going forward.

​
Area code and timezone considerations

The area code you choose during onboarding is separate from your organization’s timezone setting. Your timezone controls when scheduled campaigns send and how quiet hours are calculated—it does not have to match the area code of your phone number. You can update your organization timezone anytime in Settings > General.
