What to Know About 6-Digit Phone Numbers

You’ve likely received text messages from 6-digit phone numbers before. By now, you may have figured out that these phone numbers are used by organizations to communicate with their audiences all at once. Case closed, right? 

There’s a little more to it than that.

While these numbers may look odd next to your 10-digit phone number, they’re actually quite powerful–and popular. Every day, these shortened phone numbers enable Amazon to send verification codes to confirm new accounts, FedEx to share delivery notifications, and SouthWest to promote its flash sales.

So, what’s special about a 6-digit phone number, and how can you put this type of number to use in your business?

What Is a 6-Digit Phone Number?

A six-digit phone number is referred to as a short code (there are also some instances of 5-digit short codes). These short code numbers were created by the major wireless carriers in 2003 to allow marketers to easily communicate things like promotional offers or important alerts to consumers.

If you want to know more about these numbers, you’ve come to the right place. We’ll cover the following FAQs in this article:

• How do 6-digit phone numbers work?
• How is a 10-digit phone number different from a 6-digit number?
• How do you get a 6-digit phone number?

How Do 6-Digit Phone Numbers Work?

6-digit phone numbers are used by companies of all sizes to send marketing blasts, conduct two-factor authentication, and send out notifications and alerts. 

Six-digit phone numbers are leased from the Common Short Code Administration, and once this happens, organizations can send and receive SMS and MMS messages. It’s not a free-for-all, though and there are several rules businesses must follow to be TCPA compliant.

The most important thing to remember here is that customers must give you explicit permission to send them text messages. Anti-spam laws are no joke, and we put strong emphasis on making sure you can avoid looking spammy to your customers.

Using Keywords to Get Contacts

One of the most common ways for customers to provide this permission is by texting in a keyword. For example, a burger chain might use the keyword “BURGER.” A customer would send a text to the 6-digit number with the keyword “BURGER” to subscribe. The chain can then send this customer text messages. 

Keywords are arguably the most popular method to ensure customers are providing their explicit permission. There are a bunch of other compliant opt-in methods you can read about here. If you want to learn more about keywords and compliance, we recommend checking out the following resources:

What Is the Difference Between a 10-Digit Phone Number and a 6-Digit Number?

The biggest difference between a 10-digit phone number and six-digit number is that 10-digit numbers can also make calls and send faxes (if anyone still sends faxes). So, with a 10-digit phone number, your customers can both text and call you. 

10-digit phone numbers also allow you to send out mass text messages if they are text-enabled. If you’d like to learn more, we’ve written about how to pick the right number for your SMS marketing efforts here.

How Do You Get a 6-Digit Phone Number?

You’ll lease your 6-digit phone number. This can run your business anywhere from $1000-$1500 a month. 

If you have the budget and want to learn more about setting up a dedicated short code, then we recommend you check out our dedicated short code texting services. The first step involves deciding between a dedicated vanity short code (e.g., Kmart’s SMS short code 56278 spells out Kmart) or a dedicated random short code. 

Vanity short codes are neat in the sense that they make your 6-digit number even more memorable. However, this comes with extra costs, and random 6-digit numbers are more affordable.

Setting Up Your Short Code

The process of getting either a vanity short code or a random short code goes like this:

1. Apply to the cellular providers for one by filling out the necessary forms.
2. Once you’ve secured your short code, cell carriers test it out to make sure all the information on the forms you filled out was accurate.
3. The cellular providers give their final approval, and you are able to launch your text marketing campaigns.

With over a decade of experience with short code texting, we can guide you through the entire process to make it as smooth as possible. Get in touch with us here to get started.
