Who owns CSF Corporation?

CSF Corporation was founded in 1988 and is a privately held company acquired in late 2016 by Alpine Investors, a leading private equity firm headquartered in San Francisco, California.

CSF continues to operate as an independent business, and uses the financial backing of Alpine Investors to further grow and expand its toll-free provisioning, number management, and text enabling capabilities into new markets.

What is a RespOrg?

In the North American Numbering Plan, a RespOrg (a contraction for a Responsible Organization) is a company that maintains the registration for toll-free telephone numbers in the Somos SMS/800 database.

The Somos SMS/800 function in North American toll-free voice telephony is analogous to that of an individual registrar in the Internet's Domain Name System.

RespOrgs were established in 1993 as part of a Federal Communications Commission order instituting toll-free number portability. A RespOrg can be a long-distance company, reseller, or end user that directly controls its own toll-free numbers.

What is the overall toll-free number usage?

The toll-free industry in North America – which includes the United States, Canada, and some Caribbean countries – has a limited supply of toll-free numbers (TFNs). There are currently six open Numbering Plan Areas (NPAs): 800, 888, 877, 866, 855, and 844, resulting in a total of 47,770,094 TFNs available.

According to a 2015 report by Somos entitled, “Forecasting Utilization of Toll-free Numbers,” there are more than 40 million TFNs in use right now and the total number of currently available TFNs is forecasted to be exhausted, most likely, by Q1 2018. We expect a new toll-free number code, 833, will be made available in Spring 2017.

Why should I text-enable my toll-free numbers?

Based on a study conducted by Harris Poll on behalf of OneReach, 64 percent of consumers with texting capabilities would prefer to use texting over voice as a customer service channel. This trend underscores the importance of adding text-enabling for toll-free numbers to complement existing voice services as a way of providing better customer service and support.

The market for text-enablement of toll-free numbers is growing and expanding.

CSF’s 8MS TeXT offering supports the industry standard Somos Texting and Smart Services (“TSS”) Registry: an open, vendor-neutral repository, which delivers the same benefits that Somos SMS/800 provides for toll-free voice numbers.

To accelerate the adoption of toll-free texting and guarantee its long-term success, Somos has filed a FCC petition to reaffirm the proven and secure authority of RespOrgs over toll-free numbers across all communication services, including texting. CSF is supportive of this petition, and is confident that it will greatly accelerate the adoption of toll-free texting.

Special Programs

What is CSF’s No Risk/Shared Reward LCR Program?

CSF offers a multi-year least-cost routing (LCR) program that helps reduce toll-free carrier costs.

Using our 8MS Cloud LCRGen cloud service, we implement toll-free routing plans that use your actual toll-free CDRs, rate decks, and carrier bills as the basis for the LCR cost optimization.

As part of the program, we provide all software, consulting services, and implementation services free of charge. We are only paid a portion of the savings that our LCR optimization achieves on a monthly basis. In addition to cost savings, implementing this LCR program provides customers the added reliability of carrier diversity and disaster recovery, which we work with your team to achieve.

Please call or text us toll-free at 1-855-CALL-CSF to learn more about this unique program.
