Make it memorable.

An SMS short code has just 5 digits. Much easier to remember than 10, right?


Enable two-way chat.

Want the ability to send and receive messages? Not a problem with a dedicated SMS short code.


Look the goods.

Show your customers you mean business by using the same phone number each time you hit ‘send’.

The return on investment is amazing. It’s such a small price per text message, when you think about it, but we’ve been using them to get $90-$100 transactions. It’s just been really successful.

A dedicated SMS short code is oh-so-good for business. Here’s why.

Accelerate the pace of sending.

The sky’s the limit when you use SMS short codes for mass marketing. Without getting too technical, the speed of an outbound text message is up to 400 MPS (that’s messages per second). In other words, fast.

Ramp up opt-in marketing.

Short code texting shines for opt-in SMS marketing. To grow your subscriber list, run a simple promotion asking customers to text a keyword through. Then, sit back and watch your list grow. Too easy.

Know exactly where each chat’s at.

Every conversation with every customer is stored in a shared inbox so your team can see what’s been said before. Your customers get the full chat history on their phone, too.

Want to see for yourself?

Shared short codes were 5-digit numbers that more than one business could use. They were discontinued in 2022 because of the risk of scams — now, it’s only possible to send from a dedicated SMS short code. Learn more.

When you sign up with MessageMedia, you can choose what type of number you want to use. A dedicated SMS short code is one of four options.

If you select ‘dedicated short code’ when signing up, our sales team will contact you to help you choose a number. Then, it takes 8 to 12 weeks to process and verify your number before you can start sending.

With a vanity short code, you get to choose a memorable phone number. You might pick 5 digits that roll off the tongue (hello, 12345).

Just note, vanity short codes cost more than regular short codes (which are randomly selected, but have all the same functionality).

All short codes are leased from the Common Short Code Administration (CSCA) and involve a set-up fee. These guys maintain a master list of all available, reserved, and registered short codes.

A short code costs a few hundred dollars on top of admin fees (code costs vary). Your account manager will help you with short code administration. For more info, see our pricing.
