A2P 10DLC Registration

As of January 26, 2023, phone numbers registered through applications like Pebble are required to complete A2P 10DLC verification before they can send outbound texts. Completing this process increases the deliverability of your outbound texts and reduces the risk of carriers filtering them.

What is A2P 10DLC?

A2P 10DLC is the system US carriers use for businesses that send Application-to-Person (A2P) texts from standard 10-digit phone numbers. Carriers in the US consider all Twilio traffic to be A2P. Carriers’ A2P 10DLC offerings provide better delivery quality and lower filtering risk than long code SMS of the past, using the same phone numbers.

Registration has two parts:

1. Brand registration: you tell the carriers who your business is.
2. Campaign registration: you tell the carriers what kind of messages you send.

How to register

Fill out the A2P registration form: www.pebblerei.com/a2p

Once you've submitted the form, let us know so we can track it on our end.

Fees and timeline

• Fees: the National Registry charges a one-time $4 brand registration fee and a $15 manual vetting fee, $19 in total. It's charged to the card on file and shows on your Pebble billing.
• Timeline: approval usually takes about 2 weeks, because the National Registry and the carriers review each registration. We'll let you know when your number is cleared to send.

What you can do before approval

A2P registration only affects sending texts. While your registration is pending, you can still:

• Make and receive calls
• Receive incoming texts

You can't send outbound texts from that number until it's approved. US carriers filter and block texts from numbers that aren't registered, so a text you send before approval may fail to deliver.

Once your number is approved, texting turns on automatically. There's nothing else you need to do.

If you ported your number to Pebble

A2P approval belongs to the provider where it was set up, so it does not carry over when you move carriers or platforms. If you ported a number into Pebble, register again here, even if the number was already approved with your previous provider.

Porting and A2P are two separate processes: porting brings your number over, and A2P lets you send texts from it. See Porting Phone Numbers.

Best practices for texting

• Get consent. Only text people who agreed to receive messages from you, for example through an opt-in form. See A2P Messaging Consent.
• Keep your contacts accurate. Remove outdated or wrong numbers, which cause failed messages.
• Keep messages clear and useful. Short, relevant texts work best. Avoid unclear language and too many abbreviations or emojis.
• Respect timing. Don't text late at night, and don't send too many messages.
• Follow the rules. Learn the basics of the Telephone Consumer Protection Act (TCPA), including consent, content, and opt-outs.
• Make it easy to opt out. Honor opt-out requests quickly.
• Test and review. Send test messages and check delivery and replies so you can improve over time.
