Short Codes for SMS Marketing

Grow your mobile list and send up to 100 texts/sec with our short code texting messaging service.

What are short codes?

An sms short code is a 5 or 6 digit phone number that is used to send and receive text messages to and from a cellphone.

Unlike a 10-digit telephone number that places strict restrictions on texts sent from it, short codes can deliver large volumes of SMS text messages reliably.

CallHub currently offers short codes in the US.

What is a keyword?

A keyword is the first word sent in a text message to a short code, acting as the opt-in to a mobile list.

In “Text JOIN to 33339”, **JOIN** is the keyword and **33339** is the short-code.

When should you use a short code?

When you’re building a mobile list

Shortcodes consist of 5 or 6 digits, making them instantly memorable. This makes them perfect for text to join campaigns.

After the initial opt-in where you collect the mobile number, CallHub lets you create automated SMS follow-ups to collect details like name, email and zip code.

When you’re texting a large contact list

Short codes let you send up to 360,000 text messages per hour.

If you are currently using 10-digit phone numbers to send more than a few hundred texts per day

A 10-digit long code is meant for conversations through personal phones or via peer-to-peer texting. If you send repetitive texts to multiple people with a 10-digit number, they can get marked as spam. This isn’t a problem with short codes since they are pre-approved by wireless carriers to handle high volume and time-sensitive messages.

What are the different types of short codes?

Shared Short Codes

A shared short code is shared between multiple organizations, making it cost-efficient and faster to get started with. But your pool of keywords is limited to those not already chosen by another customer (see image).
While a dedicated short code costs $500 – $1000 and takes 8 – 12 weeks to start using, a shared short in the US costs around $25 and you can start using it in a day.
To get shared short codes within CallHub, submit a request after you create a free account.

Dedicated Short Codes

A dedicated short code gives you sole access to the short code and is shared by no other customer, allowing you to create unlimited keywords at no additional cost. They come in two types, Random Short Codes and Vanity Short Codes.

Random Short Codes

You have no control over the number assigned to you. They cost around $500 per month.

Vanity Short Codes

You choose the number you want, usually a series of repetitive numbers that are easy to remember. A vanity short code costs around $1000 per month.
To get a dedicated short code, place a request from your account after you sign up.
