Short codes: a memorable option

A short code is a five or six digit, country-specific number. Monthly costs are steeper than 10DLC. But messaging with dedicated short codes gives you higher carrier support and throughput. Great for time-sensitive communications to large audiences.

An easy process

The short code application process is more detailed than for other originators. We can help with that. The world’s biggest brands trust us to ensure their messaging with short codes runs smoothly.

Migrate with ease

If you have a well-known short code, you’ll want to bring it with you when you switch messaging providers. Our guide, Migrating short codes – the easy way, will help.

Text-enabled landlines and toll-free numbers

Many businesses like to “text enable” existing toll-free and landline numbers, so they have one number customers can either text or call on. Expect a high throughput (though not quite as high as short codes) and a secure route.

Say it with pictures

Text-enabled numbers can now also receive and deliver MMS as well as SMS. You can then send and receive images, audio and short videos – all from your familiar business number.
