The complete guide to 10DLC

Updated 1 month ago

What is a 10DLC?

A 10DLC (10-Digit Long Code) is a number that’s specifically designed and approved for business messaging in the United States of America and Canada.  It is often considered a better option for certain use cases when compared to traditional short codes or long codes. 

Here are some reasons why businesses may find 10DLC to be a more suitable choice:

  1. Cost-effective: A 10DLC can be more cost-effective than short codes. This makes it a more accessible option, especially smaller businesses with budget constraints. Short codes can be more expensive to acquire and maintain.
  2. Faster approval process: The approval process for a 10DLC is typically faster than short code approval. Businesses can get their campaigns up and running faster, which is perfect for time-sensitive promotions or communications.
  3. Versatility: A 10DLC can be used for a range of messaging, including marketing, customer support, and notifications. It’s a flexible solution for different business needs.
  4. Local presence: Local 10-digit phone numbers allow businesses to establish a familiar presence. This can enhance customer trust and engagement, especially in regions where customers are used to getting messages from local phone numbers.
  5. Scalability: 10DLC supports high message volumes. It’s great for businesses with growing messaging needs. If you anticipate an increase in messaging demand over time, a 10DLC is a great choice. 
  6. Improved deliverability: Compared to long codes, 10DLC often has better deliverability rates. Messages sent via 10DLC are more likely to reach their intended recipients, ensuring reliable communication.
  7. Reduced spam risks: All 10DLC numbers are subject to carrier and industry regulations, which helps to reduce the risk of spam. This ensures that businesses using a 10DLC follow best practices for messaging and adhere to guidelines.

There is a daily sending limit that starts from 2,000 SMS. You may be able to increase your daily limit to up to 200,000/day. Please contact support for next steps.

Mixed use cases

Campaigns can have a mixed use case. For example, your campaign can cover multiple use cases such as customer care with delivery notifications. Please note that mixed campaigns are more likely to have a lower trustscore and will lead to lower throughput/small volume of messages allowed.

For Low volume mixed use case, there will be a capping of 2,000 outbound SMS daily.

If you require different use cases and high throughput, additional campaigns can be registered to your business (up to 10).  


Your business can run up to 10 campaigns at a time. Each campaign incurs a monthly fee of $35 AUD. 

For each campaign, you can have a maximum of 49 10DLC numbers, with each number incurring an additional $5 AUD monthly cost. 

If you're a reseller, you can sign up for a number pool supporting approximately 5,000 10DLC numbers. Please contact support for setup.

Understanding age-restricted content

Content related to SHAFT (Sex, Hate, Vape, Alcohol, Firearms, Tobacco) is generally not allowed to be sent via SMS. However, messages that contain tobacco and alcohol content may be able to be sent if the sender can meet carrier approval and an age restriction/gate is in place. 

How do you meet carrier approval?

If you're planning to send promotional and/or marketing text messages about alcohol or tobacco, you would need to apply for a 10DLC number and make sure  your business is registered.

You would also need to have a high-quality age-gated opt-in method in place. For example, you might ask subscribers to confirm their age before they can sign up for messages about alcohol, tobacco, and other age-restricted content.

What is an age restriction/gate?

An age restriction/gate is like a digital bouncer—it checks the age of the person before letting them see the content. It is set up to ensure that only people above a certain age can see or interact with certain content.

The above rules help businesses to meet the legal requirements and act responsibly. It also helps to keep young people from seeing things they shouldn't.

Compare the examples below to see the difference between an acceptable and not-acceptable age-gated opt in.

Acceptable age-gated opt in form

Requires age verificationbefore subscription.

Not acceptable age-gated opt in

When you apply for 10DLC numbers to send content about age-restricted products, you must include proof of your age-gated opt in method.


The USA has very specific messaging restrictions and a direct connection is necessary to ensure message delivery to the numerous networks. ClickSend uses a high-quality, direct connection to deliver your SMS to the USA.

You can review our best practices here: US Best Practices
