Milestone 2: Select & Register Number Types
Purchase and register the number types that meet your SMS needs.
Regulatory Bundles
Before you can purchase most numbers, you must submit regulatory bundles. A regulatory bundle is a compliance package with documents to verify your business identity with local carriers and enforcement agencies.
- A local business address
- Proof of a locally-registered business
- A government-issued ID or driver’s license of authorized persons (such as directors of local business)
Short codes generally have the strictest requirements and are the most expensive, but they also have the highest throughput of any number type. Toll-free and mobile numbers typically have the fewest requirements. Many countries also require a pre-registration process for alphanumeric senders. See this Twilio article on international support for alphanumeric sender ID for more information.
Port Existing Numbers to Twilio
- Make sure you have the following items to successfully submit a port request:
- The authorized Twilio user or owner’s first and last name.
- The corresponding service address. This must be a physical address. It cannot be a PO box.
- A Letter of Authorization (LOA) signed by the authorized Twilio user and/or owner of the number. Note: The information on the LOA must match the authorized user’s name and the service address provided by your current carrier.
- A Customer Service Record (CSR).
- A scanned or electronic copy of the most recent phone bill, within the last 30 days, that includes the account, authorized user or owner’s name, and address information for all the numbers you want to port.
- We also recommend familiarizing yourself with the most common reasons for port rejection so you can better avoid them.
Allow one to two days until the SMS services route to Twilio, otherwise the A2P provisioning process might fail.
- In Twilio, go to .
- Complete the form. Be sure to attach those documents mentioned so your request isn't rejected.
- Click Submit.
- Twilio will approve your number. If you correctly submitted your port request, Twilio may approve it in 24 hours, depending on the type of number you're porting. Approval time may vary.
- Your request is then submitted to your soon-to-be former (AKA losing) carrier as a port request. This can take up to 24 hours. Do not close your account with your carrier so your numbers stay active.
- Twilio contacts your losing carrier. This can take up to one week to complete.
- You’ll receive a response from the carrier. If your request is approved, you’ll receive a porting date of when your number ports to Twilio. If your request is denied, you’ll need to contact your losing carrier to know what you need to move forward.
- Twilio contacts you by email with your porting date. Once the date passes and you receive email confirmation that the port is completed, you can use your number to call people.
- For SMS messages, complete A2P registration. Once your A2P campaign is verified, it may take up to 48 hours to update SMS routing before you add the number into the Twilio Messaging Service. Once the number moves from “Verified” to “Registered”, you can send SMS messages. You can check your 10DLC registration status in Twilio.
Purchase & Configure Phone Numbers
You should use different phone numbers for these tools versus other third-party applications, like OnlineGiving.Org text-to-give. If you already have a third party using your Twilio account, you may need to purchase additional numbers to use with these tools. Contact your third-party vendor for specific requirements.
Complete Short Code Application
Apply for a short code in Twilio through a short code link or in the short code area of Twilio.
Be sure to answer your application questions carefully and review your answers for accuracy and completeness. Inaccurate or incomplete information slows down the provisioning process and may lead to carriers rejecting your application. Once you submit your application, it may take up to eight weeks to receive approval.
