Toll-free verification
What is Toll-free verification?
Toll-free verification is the US carrier-run vetting process a business completes before sending high-volume SMS from a toll-free number (like an 800 or 888 number), confirming the business's identity, use case, and opt-in practices. Unlike A2P 10DLC's brand-and-campaign model for long codes, toll-free verification is a single per-number submission reviewed directly by the carriers' toll-free registry, and an unverified toll-free number sending A2P traffic is subject to the same filtering risk as an unregistered long code.
More detail
Toll-free verification review typically takes a few business days to a few weeks and asks for details like sample message copy, opt-in method, and expected volume.
A verified toll-free number generally supports higher throughput than an unverified one and, unlike a 10DLC long code, doesn't require a separate campaign registration per use case.
Frequently asked
- Is toll-free verification the same as A2P 10DLC registration?
- No — they're separate programs for different number types. 10DLC registers a brand and campaign for long-code SMS, while toll-free verification is a single per-number submission specific to toll-free numbers, reviewed by a different carrier process.
- What happens if I send SMS from an unverified toll-free number?
- Unverified toll-free traffic is subject to low default throughput and a high risk of carrier filtering or blocking, similar to unregistered long-code traffic, until the number completes verification.
