How do I get an SMS short code?

Last reviewed July 22, 20261 min readReviewed by BroadNet engineering

Quick answer

A short code is a 4–6 digit number leased for high-volume two-way SMS, obtained by applying through a provider or the market's short-code registry, submitting your brand and use case for operator approval, and waiting through a provisioning and vetting period. Short codes offer high throughput and strong deliverability for campaigns and OTP, but they cost more and take longer to provision than a sender ID or long code.

The long answer

Everything worth knowing, nothing that isn't.

§01

What a short code is for

Short codes suit high-throughput, high-trust use cases — OTP at scale, keyword campaigns, alerts — where you need capacity and a recognizable number the operators have vetted. See /answers/what-is-short-code and /answers/what-is-short-code-vs-long-code.

§02

The application process

You apply (through BroadNet as your provider) with your brand identity, the exact use case, sample message flows, and opt-in details. Operators review and provision the code, which is why lead times are measured in weeks, not minutes.

§03

Short code vs the alternatives

If you do not need a short code's throughput, a registered alphanumeric sender ID (for one-way branded SMS) or a long/toll-free number (for two-way at lower volume) provisions faster and costs less. See /answers/what-is-long-code and /answers/what-is-toll-free-messaging.

§04

Keep it compliant

Short codes are closely monitored: sending content that does not match the approved use case, or messaging without opt-in, risks suspension. Classify and consent correctly. See /answers/sms-compliance-checklist.
