10DLC vs toll-free vs short code is the main choice for business SMS in the United States. As of 2026, 10DLC uses local numbers registered as a brand and campaign with The Campaign Registry, toll-free uses 8XX numbers that must pass toll-free verification, and short codes are 5 or 6 digit numbers leased from the US Short Code Registry and approved by each carrier. All three need registration; the differences are setup time, throughput, cost and how recipients see you.

10DLC vs toll-free vs short code: the comparison
| 10DLC | Toll-free | Short code | |
|---|---|---|---|

| Registration | Brand and campaign with The Campaign Registry (TCR) | Toll-free verification per number | Lease from the US Short Code Registry plus carrier program approval |
| Setup time | Days to a few weeks, depending on vetting | Days to about two weeks for review | Several weeks or more |
| Throughput | Set by carriers per campaign or brand, based on trust score | Set by provider and carriers after verification | Highest of the three |
| Costs | Registration and vetting fees, monthly campaign fee, carrier per-message fees | Number rental, per-message fees | Monthly or term lease, setup fees, per-message fees |
| Recipient sees | Local area code | Recognisable national number | Short, memorable code |
| Typical use | Local business messaging, conversations, mixed use | National brands, support, OTP | High-volume alerts and marketing, keyword campaigns |
Is 10DLC better than toll-free?
Neither is better in general. 10DLC suits businesses that want a local presence and two-way conversations, and its throughput grows with the brand's trust score. Toll-free suits national senders and support lines, has a single verification per number instead of brand and campaign registration, and works for both voice and text on the same number. Many senders use both: 10DLC for local or conversational traffic, toll-free for notifications. The detailed 10DLC process is in 10DLC and toll-free SMS in the US.
10DLC vs short code: when is a short code worth it?
A short code makes sense when volume is high and steady, or when you run keyword campaigns ("Text JOIN to 12345"). Short codes are leased from the US Short Code Registry, which CTIA administers with iconectiv, typically for 3, 6, 9 or 12 months; random codes cost less than vanity (chosen) codes. After leasing, each carrier vets the program, and the application process can take several weeks. If your volume fits within your 10DLC campaign limits, 10DLC is usually the cheaper and faster choice. Short codes in general are covered in SMS short codes explained.
Short code vs long code: what is the difference?
A long code is a standard 10-digit phone number. In the US, business texting from a long code means 10DLC: a registered local number tied to an approved campaign. A short code is a separate number range used only for messaging. Long codes can also take voice calls and look like a normal contact; short codes cannot receive calls and are recognised by recipients as automated senders. Outside North America the terms differ, and many countries use alphanumeric sender IDs instead (see SMS sender ID types).
What changed for toll-free in 2026?
Toll-free verification now asks for a business registration number (such as the EIN for US companies), its issuing country and the legal entity type. Providers announced the field as mandatory for new submissions from early 2026 (dates given range from January 1 to February 17, 2026), and submissions without it are rejected. Unverified and pending numbers remain blocked in the US and Canada. The process is described step by step in toll-free SMS verification.
Which one should you choose?
- OTP for a national app: toll-free or 10DLC under a 2FA campaign; add a voice fallback (see OTP fallback).
- Local stores, clinics, services: 10DLC.
- Large marketing or alert programs: short code.
- International senders reaching US users: any of the three, but all need registration; alphanumeric sender IDs are not supported in the US.
Whatever you pick, consent rules (opt-in, STOP and HELP handling) apply to all three. See SMS content restrictions.

Frequently asked questions
Can I send SMS in the US without 10DLC registration?
Not from a local number. As of 2026 US carriers block business messages from unregistered 10DLC numbers. The alternatives are a verified toll-free number or an approved short code, which also require registration. There is no compliant way to send A2P SMS in the US without one of these.
Can a toll-free number receive text messages?
Yes. A verified toll-free number can send and receive SMS, and the same number can also take voice calls. This makes it popular for customer support lines that handle both calls and texts. Two-way messaging must still respect opt-out keywords such as STOP.
Does 10DLC work in Canada?
10DLC registration is a US carrier program. Canada has its own rules for messaging from long codes, and toll-free numbers are shared across the US and Canada, so toll-free verification covers both. Check with your provider which sender type it supports for Canadian traffic.
How much does a short code cost?
Short codes are leased, typically for 3 to 12 months, and random codes cost less than vanity codes. On top of the lease there are setup fees and per-message fees, and some carriers charge their own program fees. Ask your provider for the current total, because fees change.
Can I use the same number for 10DLC and voice calls?
Yes. A 10DLC number is a normal local phone number, so it can carry voice calls as well as registered SMS. The messaging part still needs an approved campaign, and caller ID rules such as STIR/SHAKEN apply to the voice side.
