Short code vs long code vs toll-free: which number should you text from?
A clear comparison of short codes, 10DLC long codes, and toll-free numbers for business texting — throughput, cost, approval time, and which fits your volume.
·7 min read
Before you send a business text you have to choose what kind of number it comes from, and the choice affects cost, speed, and how your messages are filtered.
There are three practical options in the US: a standard 10-digit long code registered through 10DLC, a toll-free number, or a dedicated short code.
10DLC long codes: the default for most businesses
A long code is an ordinary 10-digit phone number — the kind you already recognize. Registered through 10DLC, it can send business traffic at reasonable volume, receive replies, and take voice calls.
It is inexpensive, familiar to recipients, and appropriate for anything conversational: sales follow-up, appointment reminders, service updates, and local promotions. Throughput is limited by your registered trust tier, which is fine for most lists.
- ✓Cheapest option and fastest to get running
- ✓Looks local and supports both texting and calling
- ✓Throughput capped by trust tier — not built for instant blasts to huge lists
- ✓Requires 10DLC brand and campaign registration
Toll-free: higher throughput, national feel
A toll-free number carries higher messaging throughput than a typical long code and is well suited to national brands and support lines. It requires its own verification process rather than 10DLC registration.
The tradeoff is that toll-free reads as a business line rather than a person, which slightly dampens reply rates on one-to-one sales conversations.
Short codes: maximum scale, maximum cost
A short code is a five or six digit number leased specifically for high-volume messaging. It delivers the highest throughput and the strongest deliverability, and it is the right answer for retailers blasting hundreds of thousands of messages.
It is also expensive — a significant monthly lease plus a multi-week carrier approval process — and it cannot receive voice calls. Unless your volume genuinely demands it, a registered long code does the job for a fraction of the cost.
Key takeaways
- →Registered 10DLC long codes fit most small and mid-size businesses.
- →Toll-free offers higher throughput with its own verification process.
- →Short codes deliver maximum scale at significant monthly cost and long approval times.
- →All three require registration or verification — none can skip the carrier review.

Frequently asked questions
What is the difference between a long code and a short code?
A long code is a standard 10-digit phone number that supports calls and texts at moderate throughput. A short code is a leased 5–6 digit number built for very high-volume messaging, with higher cost, longer approval, and no voice capability.
Do I need a toll-free number to send business texts?
No. Most businesses send from a registered 10-digit local number. Toll-free makes sense when you need higher throughput or a national presence, and it requires toll-free verification rather than 10DLC registration.
Can I text from my existing business phone number?
Often yes — many landline and VoIP numbers can be text-enabled or ported to a messaging platform, then registered for business messaging. Keeping the number customers already know is usually worth the setup step.
