MMS short and long codes

MMS and SMS are both tied to the Braze SMS channel. To access MMS on your account requires the purchase of SMS for those who have not yet purchased access. Existing SMS customers can access MMS after they purchase it.

MMS is currently supported for US short codes (5-6 digit numbers), US and CA long codes (10-digit numbers), and US and Canada customer numbers. Sending numbers to numbers outside of the US/Canada is possible, but MMS messages will be converted into an SMS message with a link to the media asset. To read more, refer to Short and long codes.

MMS short codes

Some users may not implement or use MMS short codes, but they will be available if needed at a later date.

For users who got their short codes before Braze supported MMS, all existing customers with US short codes are eligible to instantly enable MMS. Reach out to your customer success manager if this situation applies to you and you would like MMS enabled.

MMS short code best practices

  • At Braze, we strongly recommend keeping transaction and promotional messaging separate, each with different short codes. Because MMS is tied to the SMS channel, and the SMS channel is highly regulated, customers may be required to pay a monetary penalty for misusing the channel and get their short code suspended (which is irreversible). Keeping transaction and promotional messaging tied to different short codes safeguards their transactional messaging.
  • If customers already have a short code dedicated to promotional messaging, and it is MMS enabled, they do not need a separate short code for MMS.

MMS long codes

Customers may send MMS with long codes. To do this, you must ensure your long codes are MMS-enabled. This can be done initially during set up, or later on from within your account.

Note that our MMS messages cannot be sent with an alphanumeric sender ID. To learn more about alphanumeric IDs, check out Alphanumeric sender ID.
