SMS Notification Error: [351] Invalid destination address value

This article outlines possible causes of the following common SMS notification error that you may encounter in the xMatters log files:

Notification Error; [351] Invalid destination address value

Possible causes of this error include:

  • The phone number belongs to a prepaid user who does not have sufficient funds to receive an SMS message.
  • The end user is not provisioned to receive SMS from all short codes or specific short codes.
    • Note: T-Mobile does not deliver short-code SMS to any of its resellers' numbers.
  • The phone number is deactivated.
  • The destination address does not belong to the mobile operator. This often happens when a user switches carriers, such as from T-Mobile to AT&T, and the systems haven't fully updated yet.

We recommend contacting your carrier to discuss issues about receiving SMS, in general, or specifically from the xMatters short code. 

Have you considered using the xMatters mobile app?
Although we continue to work with carriers, providers, and aggregators to lobby for the best end-user experience over SMS, we recommend the xMatters mobile app as the most reliable, easy-to-use, and cheapest solution for our clients.

For more information on the advantages of the mobile app, see our article: Mobile Clients vs. SMS - Why SMS STINKS.
