Sender Names (Sender ID)

A Sender Name (or Sender ID) is the name or number that appears on the recipient’s mobile device. Choosing the right identifier is critical for trust and delivery rates.

​
Types of Identifiers

Alphanumeric

Brand names (e.g., “Zeckta”). Great for one-way alerts. Not supported in all countries (e.g., USA).

Long Codes

Standard phone numbers. Required for two-way communication and support for all regions.

​
Registration Process

Most countries require pre-registration of alphanumeric Sender IDs to prevent phishing.
  1. Submission: Submit your desired name via the Dashboard or API.
  2. Vetting: Our compliance team reviews the request against regional carrier policies.
  3. Activation: Once approved, the ID becomes available for use in your POST /messages requests.
Using a non-registered Sender ID in restricted regions may result in immediate message filtering by local carriers.
