CallingPost offers two distinct text messaging options to suit your needs: short codes and toll-free numbers. This article explains the differences between each option to help you choose the best fit for your communication strategy.

1. Custom Phone Number (Toll-Free Texting)

  • Coverage: USA and major carriers in Canada.

  • Opt-in: Prior expressed consent is required, but a specific opt-in SMS response is not required. (See our documentation on acceptable opt-in methods: opt-in documentation.

  • Delivery Speed: Fast.

  • MMS: Supports MMS (multimedia messaging), increasing the character limit from 320 to 1,000 characters.

  • Personalization: Allows for better open rates through message personalization.

  • Cost: 1 Custom phone number is included on all Premium Subscriptions all other plans are $9.99 per month . This number can also be used for caller ID on phone calls.

  • Verification: Toll-free numbers must be verified before sending any text messages. The verification process can take several days. (See our verification guide: verification guide

Pro Tip: After verification, prepaying for your toll-free number for 12 months can prevent service interruptions and avoid the need to repeat the verification process.

  • Coverage: USA only.

  • Opt-in: An opt-in SMS message is required before message delivery (on the initial message only). The recipient must reply to confirm their consent.

Which Option is Right for Me?

  • Toll-Free: Best for businesses that need MMS functionality, personalized messaging, or coverage in Canada. The verification process and cost are important considerations.

  • Short Code: Best for sending high-volume, quick messages within the US where immediate delivery and cost are primary concerns. The required opt-in reply is a key factor to consider.
