Temporary fallback for unregistered Sender IDs in Spain

Spain’s Sender ID registration requirements are now in effect. To help prevent SMS delivery failures while Spain’s Alias Registry requirements are being implemented, unregistered alphanumeric SMS Sender IDs will temporarily be replaced with numeric sender identifiers.

This is a temporary measure. Once your Sender IDs are officially registered in Spain’s Alias Registry, the fallback will automatically cease, and your registered alphanumeric Sender IDs can be used as intended.

To ensure continued compliance and optimal message delivery, LINK Mobility strongly recommends registering your alphanumeric Sender IDs as soon as possible.

All requirements, deadlines, and step-by-step information are available on the Spain SMS destination page:
