There are three delivery methods that are used to send and deliver a Short Message Service (SMS) text:

• Toll-free number
• Short code
• 10-Digit Long Code (10DLC) number

Toll-Free Number

Toll-free numbers are telephone numbers with a three-digit code that can be dialed with no charge to the person dialing the number. If you already have a toll-free number at your disposal, you can configure this number to send SMSes.  Alternatively, SmartReach can provide you with a new toll-free number.

Short Code

A short code is a short digit sequence that is used to address messages in SMS systems. A short code is used in place of a phone number and has two variations: 

• Random short code - Five random numbers in no particular order (example: 435-25).
• Vanity short code - Numbers in succession that you choose, or numbers that spell a particular word.

You can lease the numbers for a short code from The Short Code Registry, or SmartReach can procure the numbers on your behalf. Short codes can either be Free to End User (FTEU), which means that the end user is not charged by the mobile operator (the business sending the message is charged), or short codes can be charged at a standard rate. 

10DLC Number

A 10DLC number is a carrier-sanctioned channel that allows you to send application-to-person (A2P) text messages using ten-digit local numbers in the United States. These type of messages include notifications, reminders,  one-time pin codes, product and service updates, and small-scale marketing campaigns.

When you complete your 10DLC brand registration with The Campaign Registry, your brand receives a Trust Score from 0 to 100. This rating influences the maximum message throughput allocated to your campaign.
