Sender ID is the alpha name or alpha-numeric name or number which appears on the mobile phone as the sender of an SMS (It is used to identify who's sending the message to the recipient). Sender ID can be a number (i.e. a Mobile Phone Number) or alpha term such as PLIVO, PLVSMS.
Sender ID is useful in uniquely identifying your business and helps with brand recall amongst your customers.
SenderIDs are specific to each country and each of these destination countries have certain regulations which Plivo and its carriers need to comply with.
- For certain destination countries, SenderIDs are dynamic, meaning that they do not require pre-registration with the respective carriers for that country.
- For other destinations, pre-registered SenderIDs do require registration with the respective carriers for that country.
For all destinations, Plivo will validate the use-case and company details and if manual checks are validated, Support will reach out to carriers to whitelist SenderID for the account so that customers can use the custom SenderID to send messages to these destinations.
The details required from the customer's end:
- Sender ID
- Company Name
- Message Template
- Use case: Transactional / Promotional
- Company Website
- Destination Countries
Customers need to keep in mind the below restrictions when applying for the SenderID feature.
- Sender ID can be between 6-11 characters depending on the destination.
- Sender ID cannot contain spaces or Hyphens.
- Sender ID's can be registered to a maximum of only 5 destinations.
- Sender ID cannot be registered for Promotional messages.
- For India the sender ID can be alpha sender ID of 6 characters only
- If you want to send messages to US/Canada using Plivo, the source number needs to be a US/ Canada Plivo number.
Sender ID cannot be registered towards US/Canada due to country/carrier regulations and restrictions.
By transactional messages, we mean:
- OTP messages
- Transactional Alerts
- Delivery Messages
Multiple Sender IDs are only supported on an account across different countries, but multiple Senders IDs for the same country is not supported on the same account. Eg. if you have registered the Sender ID "Plivo" towards Denmark from your main account, we would not be able to register another Sender ID say "PLVSMS" towards Denmark for the main account. But this can be achieved by having it registered for your sub-account.
