10DLC vs Short Codes: Which Is Right for Your Business?

Choosing between 10DLC and short codes is one of the first decisions businesses face when setting up text messaging. Both are legitimate options, but they differ significantly in cost, capabilities, and ideal use cases. This guide breaks down everything you need to make the right choice.

A Quick Overview

10DLC uses standard 10-digit local phone numbers that have been registered for business messaging. It was introduced in 2021 as an affordable, accessible way for businesses of all sizes to send text messages through carrier-approved channels.

Short codes are 5- or 6-digit numbers (like 12345) that have been the gold standard for high-volume messaging for over a decade. They are leased from carriers and go through an extensive approval process.

Side-by-Side Comparison

Cost Comparison

Cost is where the two options differ most dramatically. 10DLC was designed to be accessible to businesses of all sizes, while short codes have always been a premium product.

10DLC Costs

• Brand registration: approximately $4 (one-time)
• Campaign registration: approximately $15 (one-time for standard use cases)
• Monthly carrier fees: a few dollars per month
• Per-message surcharges: fractions of a cent per message

Short Code Costs

• Lease: $500/month for a random code, $1,000/month for a vanity code
• Setup and approval: can cost thousands in consulting and legal review
• Per-message surcharges: carrier fees per message
• Annual renewal: same lease cost every year

Throughput and Speed

Short codes have traditionally offered the highest throughput, and they still hold that advantage. However, 10DLC throughput has improved significantly, especially for businesses with higher trust scores.

With 10DLC, your throughput depends on your brand’s trust score, which is determined during registration. Higher trust scores unlock more messages per second. Businesses with good reputations and verified information can achieve throughput levels that are more than sufficient for most use cases.

Short codes typically support 100 or more messages per second, making them ideal for flash sales, voting campaigns, or any scenario where you need to blast millions of messages in a very short window.

Setup Time and Complexity

This is another area where 10DLC shines. The registration process is streamlined and largely automated. Most businesses can complete their brand and campaign registration within a few days and start sending within one to two weeks.

Short code setup is a different story. The process involves leasing the code, submitting a detailed application to each carrier, and waiting for individual approvals. This typically takes 8 to 12 weeks, and sometimes longer if carriers request changes to your application.

When to Choose 10DLC

10DLC is the right choice when:

• You want to keep costs low and predictable
• You need to start sending quickly (days, not months)
• You value having a local phone number that customers recognize
• Your messaging volume is moderate (under millions per month)
• You want two-way conversational messaging with customers
• You are a small or medium business with standard messaging needs

When to Choose Short Codes

Short codes may be worth the investment when:

• You send millions of messages monthly and need maximum throughput
• You run national campaigns where brand recognition of a short code matters
• You need a vanity number for marketing (like texting “JOIN” to 55555)
• You are a large enterprise with the budget for premium messaging infrastructure
• You can wait 2–3 months for setup and approval

Trust Score: A 10DLC Advantage

One unique feature of 10DLC is the trust score system. When you register your brand, the registry evaluates your business based on factors like your business age, online presence, and registration accuracy. Higher trust scores unlock better throughput and deliverability.

This means that established, reputable businesses get rewarded with better messaging performance. Short codes do not have an equivalent system — all approved short codes get the same high throughput regardless of the sender’s reputation.

If your trust score is lower than you would like, you can request additional vetting to improve it. This is a one-time process that can significantly boost your messaging capacity.

Making Your Decision

For most businesses, the choice is clear: 10DLC offers the best combination of cost, convenience, and capability. The only scenario where short codes make more sense is extremely high-volume messaging where maximum throughput is non-negotiable and budget is not a primary concern.

If you are just getting started with business text messaging, 10DLC is almost certainly the right place to start. You can always add a short code later if your volume grows to the point where you need one.
