Not sure which one to choose?
See our Sender ID guide or contact support — we're happy to help.
Shared numbers
Shared numbers are free, ready to use, and don’t need registration. Messages will be overwritten to either a short code or longcode, so the number might be different each time.
Shared numbers are for one-way messaging only.
Dedicated Short codes
Two-way messaging is supported in Mexico with a dedicated short code.
To purchase a short code, please contact support.
Short code registration usually takes 12–16 weeks and costs do apply.
Dedicated number (inbound only)
Dedicated numbers can only be used for receiving replies — you must include the number in the body of your message. These cannot be used as a sender ID.
To purchase a dedicated number, please contact support.
Dedicated number registration usually takes 5-6 weeks.
Rules and best practices
Opt-In Requirements
You must obtain prior consent before sending any messages.
Any form of opt-in is acceptable (e.g. web, call center, MO reply), but you must be able to provide proof of opt-in if requested by the carrier or in response to a user complaint.
Opt-Out Requirements
A clear opt-out option must be provided.
Any form of opt-out is acceptable (e.g. web form, SMS reply, call center), and you are responsible for removing opted-out users from your database.
Help Messages
Programs should support a HELP keyword to provide end users with support information — this is considered best practice.

Transactional messages (e.g. OTPs, account updates): Can be sent at any time
Content guidelines
