Toll-free SMS vs. Short Codes vs. Local Numbers

Business Messaging Quick Guide

Today’s business messaging needs have evolved, and the available market options have changed to meet those needs. No longer are businesses tied to five digit short codes for sending high volume, programmatic SMS. Toll-free SMS is paving the way for better experiences via text at the largest scale. And what about the local numbers that businesses already have? Why can’t we text-enable those?

 

Here’s a quick comparison to help you choose which option might be best for your business.

 

 

Type of Number Volume Limits A2P vs. P2P Voice Enabled? Time to Market Pricing
Local (555-555-5555) Limited to one message per second, per phone number P2P only yes Instant $
Toll-free (1-800-555-5555) Virtually unlimited messages per second, with approval A2P or P2P yes Instant $$
Short codes (55555) Virtually unlimited messages per second, with approval A2P only no Weeks or months $$$

 

What’s up with those volume limits? Why can’t I send more messages at a time on my local number?

 

It comes down to the way that carriers treat each type of traffic. Local numbers are typically used for human-to-human interaction. The infrastructure built around those numbers is set up to handle those types of use cases only – when unexpected behavior occurs, messages may get blocked by carriers and never delivered.

 

Toll-free SMS and short codes both rely on separate sets of infrastructure and spam filters – think of them as two different highways. Local numbers are more like inner city streets where speed limits are lower and there are more stop lights to control traffic. Toll-free numbers and short codes are more like interstates and highways – higher speed limits and fewer stoplights allow traffic to move freely and quickly to their end destinations.

 

A2P? P2P? What do these acronyms mean?

 

A2P stands for application-to-person; meaning, these numbers are commonly used to deliver automatic outbound alerts or notifications from an application to a person on the other end. A2P messaging is associated with higher volume outbound use cases like alerts, appointment reminders, or automatic notifications.

 

P2P stands for person-to-person; meaning, these numbers are commonly used to deliver messages from a person to another person. However, P2P messaging can still be deployed by applications. A common P2P messaging use case is something like a customer support inquiry – where a customer would send an inbound SMS to a business, and a representative from the business would respond on the other side.

Why do short codes take so long to enable?

 

Getting access to a short code takes a while due to the hefty approval process associated with each short code. Short codes are a limited commodity (there are only about 6,000 short codes), and each carrier must approve a business’s campaign before handing over the short code to ensure that each campaign is not a spam or fraud threat.

 

Toll-free numbers are approved for similar high-volume use cases as short codes, but without all the red tape. This isn’t to say toll-free SMS is an appropriate avenue for spam and fraud – quite the opposite. A responsible toll-free number provider (such as Bandwidth)  should have a series of checks and balances built into their contract process to ensure that the toll-free SMS channel remains spam-free.

What if I don’t want to buy a new toll-free number just for texting?

 

That’s one of the biggest reasons why toll-free SMS is such a great alternative to short codes – you can text-enable your existing toll-free phone number. One number to promote for both voice AND messaging translates to a better overall user experience for your customers. No searching around for a phone number after receiving a time-sensitive alert – just text or call back the same toll-free number.

 

Locked into a contract with your current voice provider? There are options available for you, too. Most carriers will provide a letter of authorization allowing you to take just your messaging business to a different provider, letting you get started quicker without having to ride out an outdated contract.
