US Local Phone Number Registration

What is 10DLC?

"10DLC" is short for 10 Digit Long Codes, commonly referred to as local phone numbers. 

Businesses will be required to register their brand and define the types of campaigns they will use when sending text messages using local phone numbers to United States customers. 


What does this mean for my business?

In order to comply with these changes, Sakari customers will be required to do two things:

  • Register your brand. This will provide basic information on your business including address, website, vertical, etc. 
  • Register your messaging campaign(s). This will describe how you will be messaging your contacts. You will be asked to describe your use case, campaign description and provide sample messages for the campaign.  Regardless of whether you send 1:1 messages or bulk messages, you must select a campaign type. 

Please register both your brand and campaign by filling out this form.  


NOTE: After submitting your brand and campaign submission your information will be sent for review. All submissions may require further information prior to approval.


What are the fees/costs associated with these changes?

There will be several fees that are passed on. These fees are passed-through from the carriers and are  subject to change.

Month Savings
Brand Registration $4, one-time fee
Campaign Registration Fee $15, one-time fee
Campaign Monthly Fee $10/mo per campaign, paid quarterly
Carrier Per Message Fees $0.002-0.005 per message; currently being paid by Sakari.
Additional Vetting (Optional) $40, one-time fee (Optional).


What are the campaign use cases?

Each brand will have to register its campaigns. You'll need to provide a campaign description and two sample messages per campaign. Below are the possible use cases for campaigns.

2FA Any authentication, verification, or one-time passcode

How do I register?

Please register both your brand and campaign by filling out this form. 

Sakari will input this data into The Campaign Registry and will reach out to you for additional information if needed.


What if I don't send Campaigns, I just send 1:1 messages? 

"Campaigns" are the general term used by carriers for the type of messaging sent.  Regardless of whether you send 1:1, bulk or automated text messages, all businesses messaging to the United States on local phone numbers are required to register. 


I'm based out of Canada, do I need to register?

If you're messaging from a Canadian number only to Canada, you do not need to register.  If you're messaging from Canadian number to the United States, you will need to register. 


What happens if I don't register my brand? 

Carrier restrictions will be imposed and you are subject to additional fines. Additionally, text messages to AT&T, T-Mobile, and Sprint customers based in the United States will likely be blocked.


What if my brand comes back Unverified?

An Unverified status means that the EIN/Tax ID that you previously submitted does not match your legal company name. You'll have to resubmit the correct information if you want to continue messaging. You may be charged again for the resubmission.


What if I already registered my brand but need to edit my information? 

If you need to correct previously submitted information or update your brand details, you may be charged again for a resubmission.


What is secondary vetting?

If you are a high-volume business and want to increase your throughput rates for messaging, you can go through an annual vetting process. Secondary vetting is an additional brand review done by carriers that allows for higher daily messaging limits and maximizes throughput per campaign.  

This is optional and is an additional $40 fee.  There is no guarantee that additional throughput will be granted, and the $40 fee is non-refundable. 

To request secondary vetting, please email our support team at


What are my alternative options?

The restrictions and fees above only apply to businesses sending from local phone numbers.  Customers sending text messages from toll-free phone numbers are not impacted. There is no cost to switch to a toll-free number and you won't be required to register your brand and campaigns. Reach out to us at to update your account to a toll-free phone number. 


What’s the purpose of A2P 10DLC?

The purpose of creating 10-digit long codes is to help increase security and protect consumers/end-users by filtering unwanted messages.
