Short Code Carrier Reach

The link below provides carrier reach lists for both the U.S. (sheet 1) and Canada (sheet 2) for both SMS and MMS, as well as SMS & MMS DLR and FTEU program availability for U.S. carriers.

The following reach list is effective 3/1/2018.

FTEU Short Code Program Reach

There may be a few Tier 3 carriers who, while listed in the above reach document, do not support FTEU. Also, please note that U.S. Cellular, who approves FTEU on a case-by-case basis, and will not approve FTEU programs without presentation of a business case which leans toward large-scale needs such as banking alerts and/or OTP for large companies.

Long Code Carrier Reach

The reach lists contained within the spreadsheet below align with Aerialink Subscription Plans. Please contact to add additional Plans to your account that will extend your reach.

The following reach list is effective 12/1/2018.

Note: MMS DLR is available through MM4 connection only.

U.S. & Canada+ Long Code Plan

This reach list can be found on the first sheet of the Aerialink Long-Code Reach spreadsheet. The reach of this plan includes +1 country code destinations and any other countries that do not impose a message surcharge fee.

International Reach Long Code Plan

This reach list can be found on the second sheet of the Aerialink Long-Code Reach spreadsheet.The International Reach Long Code Plan includes carriers worldwide. Most of the countries included impose a per message outbound surcharge fee. By default, the International Plan will allow your codes to reach all of these countries and their associated surcharge fees will be applied to your invoice. If you need to restrict any of your long codes from reaching specific countries, please send a list of those countries and your associated long codes to and we will apply the restrictions to those codes.

Keep in mind that not all destinations and/or carriers support two-way(inbound and outbound) delivery. Some may allow only one-way(outbound only) delivery to an end-user, thereby disallowing the end-user from replying to the message. This reach list provides visibility to one-way vs. two-way support.

Please check the Messaging Fees page for country-by-country surcharge information.
