Sender IDs are specific to each country. Every country has regulations with which Plivo and its carriers must comply.
- For certain countries, sender IDs are dynamic, meaning that they don't require pre-registration with those countries' carriers.
- For other countries, sender IDs do require pre-registration with carriers. Messages may not be delivered if the sender ID is not pre-registered.
