Short Codes

Special 5 or 6 digit numbers that typically has higher delivery rates but with a fee.

Last updated on November 19, 2021

Short codes are special 5 or 6 digit phone numbers that can be used for both SMS and MMS messaging. They typically have higher delivery rates than traditional long code numbers, but as a result come with a hefty price tag.

If you already have a short code phone number you can port it into Avochato. You also have the option to lease a short code number through Avochato. Reach out to our sales staff for an estimate at (415) 214-8977.

Application Process

Because short codes are federally regulated and must also be approved by our provider as well as all participating carriers, the application process can be lengthy. Once you submit your application to us, we will review it to make sure it is compliant with carrier requirements and federal regulations (CTIA).

After final submission it can take from 8-12 weeks on average for carriers to review and approve short code applications.

What are the federal limitations on Short Code messaging?

Short codes are federally regulated and therefore must adhere to CTIA (Cellular Telecommunications and Internet Association) Messaging Principles and Best Practices guidelines. These impose limitations on messaging that include (but are not limited to) topics of firearms, drugs (including cannabis), alcohol, and tobacco.


As short code phone numbers are in limited supply, they incur higher costs. Short code specific fees are as follows:
