One number for calls and texts your customers already know
SMS-enable your existing or new toll-free business line and give customers a single, trusted number to reach you by voice or text, with no disruption to your existing service.
What is toll-free SMS?
A toll-free number is a 10-digit business phone number with an 800-series prefix, the kind businesses have used for decades to give customers a free, easy way to get in touch. Today, those same numbers can send and receive text messages just like any other business number.
SMS-enabling your toll-free line means customers don't need to save or remember a separate number to text you. One number handles everything — calls, texts, and the trust that comes with a number they already recognize.
Why text-enable your toll-free number?
One number, two channels
Your toll-free number can handle both voice calls and text messages simultaneously. Customers reach you the way they prefer, and you never miss a message from someone already trying to text your business line.
No disruption to existing service
SMS-enable your current 800-series number without replacing it or moving it. Your voice service stays exactly as it is and SMS is simply added on top.
A number customers already trust
Toll-free numbers carry instant credibility. Customers recognize the format, know it's a legitimate business, and are more likely to engage with messages coming from a number that looks familiar.

Frequently asked questions
A toll-free number is a 10-digit phone number with a recognizable prefix like 800, 888, 877, or 833 that is free for callers to dial. In addition to voice calls, toll-free numbers in the US and Canada can send and receive SMS and MMS messages, making them a versatile option for business communication.
Toll-free texting works like standard business messaging. Customers can text your toll-free number and receive replies, appointment reminders, order updates, and promotional messages. Messages are sent and received through the same APIs used for long code and short code messaging.
Toll-free verification is a process where you submit your business information and messaging use case to confirm you're a legitimate sender. Carriers require this to prevent spam and ensure high deliverability. Unverified toll-free numbers face significantly lower throughput limits and risk having messages filtered or blocked.
Toll-free verification typically takes between 1–3 business days, though it can vary depending on the completeness of your submission. Having your business details, messaging use case, and sample messages ready can speed up the process.
Toll-free numbers use recognizable prefixes (800, 888, etc.) and are verified in-house by the messaging provider, while 10DLC numbers use local area codes and require external campaign registration with The Campaign Registry (TCR). Toll-free numbers offer handset-level delivery receipts and generally faster verification, while 10DLC numbers provide a local presence that can improve trust with recipients.
Verified toll-free numbers support higher messaging throughput than unverified numbers. Once verified, toll-free numbers can typically handle several messages per second, suitable for most business messaging needs. For high-volume campaigns requiring faster throughput, consider short codes.
