What is a Short Code?

  • A short‑code is a special 5‑ or 6‑digit number you use to send & receive SMS/MMS messages.

  • It’s meant for messaging large audiences (thousands of contacts).

  • Using a short‑code helps avoid having your messages flagged as spam by mobile carriers.

  • Note: Short codes are only available on Premium plans in Salesmsg.

When You Can’t Use a Short Code

There are certain uses or industries where short codes are restricted - meaning you won’t be allowed to use them. Some of these are:

Restricted Use Case

Examples

Illegal products/services federally or in any U.S. state

Anything banned or heavily regulated across the board

“High‑risk” financial services

Such as certain loans, debt relief, etc.

Gambling

Lotteries, betting, etc.

Work & investment opportunity promotions

Scams or risky investment pitches

Lead‑generation where info is shared with 3rd parties

If you’re collecting personal data and selling/sharing it

Competing directly with telco services

For example, if your messaging competes with what phone companies offer

Frequently Asked Questions

Will My Short Code Work Internationally?

No - short codes do not work internationally. Short codes are country-specific and must be provisioned separately for each country. At this time, Salesmsg only supports short codes in the United States and Canada.

If you need to message recipients outside of these countries, consider using alternative methods such as:

  • 10DLC (10-digit long codes)

  • Toll-free numbers
