Does Plivo support alphanumeric sender ID for SMS?

Plivo supports the use of alphanumeric sender IDs, however, you must whitelist your account by contacting Plivo support to enable this feature. Your request should include the sender ID you wish to use, the destination countries you intend to reach, and your specific use case in the support request.

In addition to Plivo’s restrictions on the use of alphanumeric sender IDs, country-specific restrictions may also apply. In some countries, alphanumeric sender IDs must be pre-approved by the local regulatory bodies. In other countries, no such approval may be required. For countries where regulatory bodies mandate pre-approval of sender IDs, Plivo will facilitate the approval process.

The whitelisting process can take up to three business days if approval from local carriers and regulatory bodies is not required. Approval from local carriers and regulatory bodies may take up to eight weeks.

Alphanumeric sender IDs are not supported in the US and Canada.

Contact us with your specific use case for more details.

Why would Plivo reject my request for alphanumeric sender ID whitelisting?

Plivo will first and foremost seek to verify the legitimacy of your business, as it applies to the sender ID you wish to use. In some cases, we may request an official authorization from your organization’s legal department verifying the use of the requested sender ID. If your sender ID is based on a specific product or service that your company provides, Plivo may seek specific information to establish this association.
