SMS Code Provisioning Guidelines
Use a Mexico short code for alphanumeric codes one-way sends. You can register up to 7 alphanumeric codes. Network carriers must approve and allowlist all alphanumeric codes before deployment. These codes must have a minimum of 3 and a maximum of 11 alphanumeric characters.
You can also use short codes for two-way sends marketing and transactional sends, but not all network carriers support these sends.
Network carriers require monthly sending rates of at least 100,000 sends per month to keep a short code active. We recommend planning your sending rate as soon as possible before procuring a short code. Conduct marketing sends from Monday through Friday, 9 AM to 8 PM (UTC−03:00 or -04:00, depending on the season).
