How much does 10DLC cost?

Short answer: through Twilio or Telnyx, registration costs about $20 up front. That's $4.50 to register your brand and $15 to have your campaign reviewed. After that you pay $1.50 to $10 a month per campaign, about $1 a month per number, and roughly a cent per text.

For a small office sending 500 one-segment reminders a month through Twilio, the first year comes to about $131. That's $19.50 to register, $18 for a low-volume campaign, $13.80 for one number, and at most $79.80 in message and carrier fees.

These numbers drift. TCR raised brand registration and vetting fees on August 1, 2025, and each provider passes them through differently. I checked every figure on this page in October 2026 against the provider's own pricing page, linked under each table. Check yours before you budget.

One-time fees

• Brand registration: registers your business with The Campaign Registry. You pay it once per brand. Twilio and Telnyx pass TCR's $4.50 through at cost.
• Brand vetting (optional): an extra review of your business that can raise your trust score and your sending limits. Twilio folds it into a $46 Standard brand fee. Worth it if you send real volume.
• Campaign vetting: $15 to review your campaign. Twilio charges it once per campaign, so editing and resubmitting a rejected one costs nothing more. Delete it and start over and you pay again. Telnyx charges $15 per review and says its team may submit a campaign more than once.

Monthly fees

• Campaign fee: a recurring fee for each active campaign. Low-volume mixed campaigns are capped at 2,000 segments a day to T-Mobile, which covers most small offices.
• Billing terms differ. Twilio bills the campaign fee at approval, then monthly. Telnyx bills the first three months up front. Bandwidth charges a three-month minimum even if you cancel early.
• Phone number: a monthly rental for each number you text from
• Platform plan: if you use a texting app instead of an API, its subscription is often your biggest monthly line

Per-message fees

Every text has two costs: your provider's price per message and a carrier fee the provider passes through to you. Carrier fees differ by carrier, so your bill depends partly on which carriers your customers use.

• Provider rate on top: $0.0083 per SMS segment at Twilio, $0.004 at Telnyx. So one plain-text reminder to a Verizon customer costs $0.0133 through Twilio.
• Replies cost too. AT&T charges $0.0035 and T-Mobile $0.0025 per inbound SMS segment. Verizon charges nothing inbound.
• The same carrier can bill differently through different providers. Verizon SMS is $0.005 on Twilio's table and $0.0045 on Telnyx's.

Long texts cost more than you think

You pay per segment, not per text. A plain-text message fits 160 characters in one segment. Go over and it splits into segments of 153 characters each. Add one emoji or certain special characters and the whole message switches encoding, so each segment holds only 70 characters, or 67 once it splits. Same reminder, two prices:

The cost that isn't on the invoice

A rejection can cost you another $15 vetting fee, depending on your provider and whether you fix the campaign or start a new one. That's the small part. Re-review commonly takes one to four weeks, and your texts don't go out while you wait. For a business that runs on appointment reminders, that means no-shows, missed jobs, and staff time spent calling instead. Each rejection restarts the clock.
