ABOUT

Short code messaging service

Reach users at scale wherever they are in the world—set up numbers in the Short Code Registry and send messages through Telnyx. Get a vanity number or a memorable short code number—both are ideal for SMS marketing, notifications and even 2-way conversations.

FEATURES

High volume, recognizable short code numbers

Send from a 5-digit recognizable code so customers will know it’s you. Extremely high throughput limits and lower ongoing compliance thresholds make it easy to scale.

    SMS short code is the highest volume number type, supporting up to 100 message parts per second (360,000 per hour).

    Recognizable short code texting numbers

    Create or reinforce a brand your customers know and love. Get an automatically-assigned code or request a special one.

    Unlike number types that only support carrier network receipts, short code also includes handset receipts, so you can be confident your message was delivered.

  • Checkmark

    Low-maintenance compliance

    After completing a comprehensive initial vetting process, ongoing compliance requirements for short code are lower than other number types, reducing delivery and compliance issues.

  • Checkmark

    If a customer replies with a stop word (e.g. “STOP”), Telnyx will automatically unsubscribe them from future sends from that number.
