Got questions? We've got answers!

  • What is a toll-free number?

    Toll-free numbers enable two-way SMS across the US and Canada. 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 types of numbers can run toll-free messaging?

    You can run messaging on any toll-free prefix available today: 800, 888, 877, 866, 855, 844, and 833.

  • Can I use my own number or will Sinch procure one for me?

    Sinch can text-enable your 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 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 services, but you can also enable only SMS messaging with us if you wish.

  • Can I shift my traffic from a short code to a toll-free number?

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

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

    The standard throughput is 10 messages per second. Higher throughput is available, depending on use case, at speeds comparable to short codes. Contact us to get more information.

  • Do I need to register my toll-free campaign?

    Yes, you must register your toll-free campaign by completing a Verified Sender Form. The Verified Sender Form is a lightweight onboarding process that ensures better deliverability, fewer restrictions, and reduction of false positive blocking and filtering.

  • What's a delivery receipt, do they work on toll-free numbers?

    There are two types of delivery receipts in relation to SMS messaging: a network delivery receipt and a handset delivery receipt. A handset delivery receipt is a receipt from a consumer's handset that a message has been received. Toll-free numbers, in most cases, support handset delivery receipts. 

  • Do toll-free numbers support SMS and MMS?

    Yes, toll-free numbers support SMS and MMS messaging. 

  • 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.
