Got questions about toll-free SMS? We've got answers!

  • What is toll-free SMS?

    Toll-free numbers are 10-digit numbers for U.S. and Canada that begin with an 8XX prefix. Toll-free numbers include 800, 888, 866, 855, 844, and 833 prefixes. They can also be enabled for two-way SMS. These numbers allow callers to reach businesses and individuals without being charged a long-distance fee. Wireless callers, however, will be charged for the airtime minutes used during the call unless they have "unlimited calling."

  • What are the advantages of toll-free texting?

    Toll-free numbers are easy to remember and easily portable, which supports better customer experiences. They also help businesses earn trust and establish credibility with their customers.

    Toll-free texting offers customers a way to communicate effortlessly with your business through numbers you may already have, which helps improve customer satisfaction. Your business gains a new, affordable and effective channel to engage customers at scale – and you’ll get handset delivery receipts (that means message delivery receipts come from the customer’s phone), so you know your texts were received.

  • Can my 800 number receive text messages?

    Yes, any toll-free number can receive and send SMS or MMS messages if it is text-enabled.

  • How does my business get a toll-free number that’s text-enabled?

    Sinch can text-enable your business’s toll-free number or procure you a new one. Text-enabling your existing number won’t affect voice service on the number. Messaging and voice operate independently, so there'll be no impact on your voice service.

  • Do voice and SMS services need to be from the same provider?

    No, you can use different providers for voice and SMS with a toll-free number since voice and messaging on a toll-free number run completely independently from one another. Sinch can provide both voice and SMS services or individual solutions that work with your current set-up.

  • Can I switch from a short code to a toll-free number for SMS?

    In most cases, yes. However, in some situations, a short code is a better solution (e.g., very high-volume messaging campaigns).

  • What is the throughput for a toll-free number?

    The standard throughput is 10 messages per second. High throughput toll-free numbers are available, depending on use case, at speeds comparable to short codes. Contact us to get more information.

  • What is toll-free messaging verification, and do I need it?

    Requesting verification for your toll-free number ensures better text message deliverability, fewer restrictions, and reduction of false positive blocking and filtering. You must register your toll-free number by completing a Verified Sender Form. 

  • What are some best practices for toll-free messaging?

    - Avoid using public URL shorteners. These are used by spammers and are mostly blocked on toll-free numbers. Create a custom URL shortener that is only used by your brand.    

    - Ensure you have proper consent.   

    - Support HELP and STOP commands.    

    - Use only one toll-free number for all your messaging.
