One simple, usage-based price. Free to start with a $5 credit, then pay only for the numbers and messages you send. Every carrier and registration fee is passed through at cost.
Custom volume pricing from $0.0060/segment, dedicated carrier capacity, custom SLA, and security review support.
Carriers split every SMS into fixed-size chunks called segments. You pay per segment. Understanding encoding saves you money.
Standard ASCII letters, numbers, and common punctuation. One segment holds 160 characters. Multi-part messages use 7 bytes for reassembly headers, so each subsequent segment holds 153 characters.
A single emoji, accented character, or non-Latin script forces the entire message into UCS-2 encoding. One segment holds 70 characters (or 67 in multi-part). That one 👍 can double your segment count.
Type a real message, pick the recipient's carrier, and watch the segments and cost update live. Try adding an emoji.
Calculator estimates are for modeling only. Actual charges may vary based on encoding, carrier classification, registration state, destination, retries, MMS handling, provider fees, taxes, and carrier fee changes.
These surcharges are set by the carriers, not by us. We show every rate on this page so you can calculate costs without digging through docs.

Every business on 10DLC registers a brand with The Campaign Registry. The registration tooling is built in, and the registry and optional vetting fees pass through at cost, with no markup.

Brand registration is a one-time fee set by The Campaign Registry; most businesses register one brand. Optional third-party identity vetting (standard or enhanced) can speed campaign approval and unlock higher throughput. All fees are passed through at cost with no markup.
A campaign authorizes a specific use case: marketing, 2FA, notifications, and so on. Each carries a recurring fee set by The Campaign Registry, passed through at cost.
| Campaign use case | Price | Cadence |
|---|---|---|
| Standard use cases (marketing, 2FA, notifications, customer care, security, social…) | $10.00 | / campaign / mo |
| Low-volume mixed | $1.50 | / campaign / mo |
| Sole proprietor | $2.00 | / campaign / mo |
| Charity | $3.00 | / campaign / mo |
| Emergency | $5.00 | / campaign / mo |
| Agents & franchises | $30.00 | / campaign / mo |
Every 10DLC use case is a separate campaign with a recurring fee set by The Campaign Registry. We file each campaign for you and pass the fee through at cost with no markup. Most agents need one campaign; special use cases such as charity, sole proprietor, and low volume carry lower rates.
