Go to Settings > Phone Numbers

Click Settings in the left sidebar and select Phone Numbers.

Choose country and number type

Select your country. Then choose between a local number (a regional area code) or a toll-free number (e.g., 1-800).

Step 4 — Complete A2P 10DLC registration

A2P 10DLC is a US carrier requirement for businesses sending SMS messages. Without registration, carriers will filter or block your outbound SMS.
A2P 10DLC registration is mandatory for all US SMS. Start this immediately after purchasing your number — approval typically takes 1–5 business days.
Go to Settings > Trust Center to begin registration. You will need:
  • Your legal business name (exactly as registered)
  • EIN / Tax ID
  • Business website URL
  • Business type (LLC, Corporation, Sole Proprietor, etc.)
  • A description of how you will use SMS

Using multiple phone numbers

You can purchase additional numbers for different purposes — for example, a separate number per team member, or a dedicated number for each marketing campaign. Each number has independent call and SMS settings.
When using the dialer, you can choose which number to call from using the From dropdown — useful if you have multiple numbers assigned to your account.

Frequently asked questions

Local US and Canadian numbers are typically a low monthly fee (around $1–2/month) plus per-minute and per-message usage charges. Toll-free numbers are slightly higher. Pricing is shown during the purchase flow. Check your HoopAI plan details for included credits.
Yes — number porting is available. Contact HoopAI support to initiate a port request. The process typically takes 2–4 weeks and requires a Letter of Authorization (LOA) from your current carrier.
A2P 10DLC is primarily required for bulk/campaign SMS. Low-volume 1-on-1 conversational SMS may work without full registration initially, but carriers can still filter unregistered traffic. Complete registration promptly to ensure reliable delivery for all SMS.
Rejections are usually due to incomplete business information or a mismatch between your legal name and EIN records. Review the rejection reason in Settings > Trust Center and resubmit with corrected information. Contact HoopAI support if you need help resolving a rejection.
Yes — international SMS is supported for many countries. Purchase or use an existing number that supports international sending, and ensure the contact’s phone number includes the correct country code. Additional per-message rates apply for international destinations.
