Understanding Number Types

The type of communication you want to have with your users or customers will determine what number is best for you.

🚧

This page does not include 10DLC information at this time as the FreeClimb team is still hard at work getting our platform ready for those changes. Please check back for updates as we continue to prepare for 10DLC, especially as number capabilities and limitations are very likely to change in the coming months.

Types of FreeClimb numbers

FreeClimb currently supports US-based long code and toll-free phone numbers for inbound and outbound SMS and voice services.

Long code (local) numbers are the most common type of number. For example, a local mobile phone number is a long code number. They have 10 digits, the first 3 of which correspond to the number's exchange code, commonly called an area code. Overall, local numbers feel personal and familiar. For some local businesses and organizations, this might make a local long code number the best choice.

Toll-free numbers use a specially designated exchange code, like 800, 888, 877, 866, 855, 844, or 833. The name "toll-free" comes from the numbers' original purpose, which was to give individuals a way to contact businesses without incurring any long-distance or call minute charges. This still applies today, although only for landline callers. Toll-free numbers are specifically business-related and can be made more memorable with phrases. For businesses with a widespread customer-base or a strategic marketing need, a toll-free number could be the better fit.


While trial accounts have some limitations on outbound communication and use of multiple numbers, there are no restrictions on the types of numbers that you can purchase with an upgraded account.

Trial accounts are automatically assigned a long code number

Because trial account limitations align with most local long code use cases, your trial account will automatically be assigned a local long code number. However, once you upgrade your account, make sure to match your use case with the appropriate number type by referring to the table below in order to avoid carrier filtering, blocking, and/or potential suspension of your account.

Outbound messaging limits for all number types

Due to outbound messaging changes for both long code (10DLC) and toll-free numbers, all FreeClimb accounts have outbound messaging limitations per number. Each phone number, regardless of type, will be limited to 200 outbound messages per day at this time. If you're interested in sending more than 200 messages per day, please contact support.

Carrier filtering

Yes. Carriers will filter and block most A2P messaging use cases and suspected spam based on content and messaging per second. Very soon, all outbound messages will be blocked unless the phone number is registered to a 10DLC campaign (more information about what 10DLC is and how to register coming soon).

Yes. Carriers will filter and block users who are suspected of sending spam or nuisance calls and messages. See FreeClimb's Acceptable Use Policy and CTIA Best Practices to avoid any violations which may lead to filtering, blocking, and/or suspension of your account.
