Take Ownership and Control of Your Phone Numbers with NumHub.

In this guide, we will explore authoritative ownership of phone numbers, why it's essential for businesses, and how to take control of your phone numbers. We’ll break down the misconceptions, highlight the benefits, and show how owning your numbers can protect your business from disruption, fraud, and carrier dependence and empower you to take control of your brand's identity and integrity.

If I Don't Own and Control My Phone Number, Who Does?  

When you sign up for phone service, your assigned number might feel like it’s yours, but technically, you are only "renting" the number from your carrier. The carrier retains what is known as the right-to-use in the central regulatory database, meaning they are the subscriber of record—not you. As a customer, you are granted temporary usage of the number while your service agreement is active, but beyond that, you hold no formal ownership or control.  

In practical terms, this means that although you can use the number to make calls, send texts, or run your business, the carrier has the ultimate control over it. You cannot manage the number independently in the regulatory system. The carrier, as the registered owner in the database, can reassign or revoke the number under certain circumstances, such as if your service ends or if the number needs to be reallocated.  

This lack of control can cause problems if you want to port your number to another carrier or ensure long-term use of it without interference. Further, without control of your number, your identity is at risk of spoofing, a form of fraud where bad actors can hijack your phone numbers and pretend to be you. True ownership and control means moving beyond "rental" status and taking complete legal and operational control of your phone number at the regulatory level.  

This article will focus on three paths to phone number ownership and control. First, for inbound calls, we will discuss how NumHub empowers you to take control of your toll-free numbers by assigning you a unique RespOrg ID. Second, NumHub is poised to bring the same regulatory advantages to local phone numbers, leveraging ALT SPIDs to deliver disaster recovery and multi-carrier routing. Third, for outbound calling, NumHub now actively participates in the Branded Caller ID (BCID) system, acting as an onboarding and vetting agent responsible for verifying a given phone number user's identity and issuing a Stir/Shaken Certificate (also known as a passport or token) for outbound calls to establish your right-to-use. This will allow brands to establish themselves as the verified phone number owner making the call and deliver their logos with a verified identity check mark on outbound calls to increase answer rates.

Let's Review a Few Definitions to Help Us Along  

Before we discuss the benefits and specifics of owning your phone number, let’s review a few key terms that will help clarify the discussion.  

RespOrg (Responsible Organization)  

A RespOrg manages and controls toll-free phone numbers within the SMS/800 database, the centralized system for toll-free numbers in the U.S. and Canada. Typically, carriers serve as RespOrgs, but businesses can also become their own RespOrg to gain complete control over their numbers. Becoming a RespOrg allows you to port, route, and manage your toll-free numbers independently without relying on a carrier.  

SPID and ALT SPID  

A SPID, or Service Provider ID, is the identification code assigned to a local carrier within the NPAC database, the centralized system for local phone numbers in the U.S. Unlike Toll-Free numbers, local numbers are not divorced from the phone number's routing, meaning they must be assigned to a carrier to work. ALT SPID is a secondary field created during the formation of NPAC as a failsafe but can now be used to add secondary ownership information for a given phone number. 

Right-to-Use  

Right-to-use refers to being the subscriber of record for a phone number as recognized in the regulatory database. While you may be the user of the number assigned by your carrier, they are technically the subscriber of record unless you take action to gain ownership. Having right-to-use means that you have direct control of the phone number’s assignment and routing within the regulatory system, allowing you to dictate how the number is used and who can access it.  

Subscriber of Record  

The subscriber of record is the entity recognized as the official holder of the phone number’s right-to-use. In most cases, this is the carrier, even though you, as the user, might be making the calls. To fully control and own your number, you need to be recognized as the subscriber of record, meaning your business, not the carrier, is listed as the authoritative owner either in the appropriate regulatory database or on a Stir-Shaken certificate.  

Stir/Shaken  

Stir/Shaken is a set of protocols designed to prevent caller ID spoofing by authenticating the caller's identity. It works like an SSL certificate for phone numbers, verifying that the call comes from the actual subscriber of record. To obtain a Stir/Shaken certificate, you must have authoritative ownership of your phone number through NumHub's onboarding and vetting platform. This ensures that your business’s calls are trusted and less likely to be flagged as spam.  

By understanding these definitions, you’ll better understand what it means to own your phone number and its technical landscape.  

What's the Benefit of Establishing Ownership and Control of My Phone Numbers?

Establishing ownership and control of your phone numbers brings many traditional and more recent advantages that go beyond the convenience of keeping it with your carrier. Let’s break this down into two parts: the traditional benefits that have long been recognized by those who manage phone numbers and the newer, evolving benefits that are crucial in today’s telecom landscape.

Vendor Neutrality:

NumHub started in the toll-free number space as an independent RespOrg, meaning we have and continue to remain carrier and vendor-neutral. This neutrality has allowed us to empower our customers to own and control their toll-free numbers independent of their carrier partners, allowing for multi-carrier routing, among other benefits. As we develop the ALT SPID function in NPAC, we are poised to bring this ability to local numbers.  Businesses that utilize vendor neutrality are protected from outages, have better negotiating power with vendors, and never have to worry about losing their numbers.

Disaster Recovery:

Ownership and control of your phone numbers is crucial in disaster recovery planning. If your primary carrier experiences an outage or disruption, you can quickly and easily reroute your phone traffic to an alternate carrier. This ensures business continuity and minimizes the risk of downtime on inbound calls, which is critical for customer support lines and business operations.

Least Cost Routing:

With ownership and control of your phone numbers, you can implement least-cost routing strategies to save on inbound calling costs. This allows you to route calls cost-efficiently, choosing the least expensive paths for your voice traffic. The result is significant cost savings, especially for businesses that handle large volumes of calls on toll-free numbers. 

Access to Source of Truth Information:

By establishing ownership and control of your phone numbers with NumHub, you gain direct access to critical data about them. This "source of truth" information includes accurate, real-time data about number assignments, ownership, and routing. This information allows you to make informed decisions and ensures you have complete visibility into the status and usage of your numbers.

Fraud Detection:

Phone number fraud is a frequent and persistent issue in telecom. Ownership and control of your numbers gives you the tools to detect and prevent fraudulent activity, such as unauthorized porting or spoofing. Direct access to regulatory data allows you to monitor your numbers and respond quickly to suspicious behavior, protecting your business from potential fraud and identity theft. 

Brand Integrity:

As telecom security evolves, ownership and control of your numbers enables you to protect the integrity of your brand. Stir/Shaken is essentially an SSL certificate for phone numbers designed to authenticate the caller and prevent robocalls and spoofing. By proving authoritative ownership of your number through a Stir/Shaken certificate, you can secure your brand and increase customer trust.

Brand Identity:

Looking to the future, ownership and control of your phone numbers opens the door to Branded Caller ID services. With Branded Caller ID, your business can display its logo and verified identity directly on the recipient’s handset, boosting brand recognition and call engagement. While this feature is still being rolled out across the industry, it will soon empower your business to protect brand identity and make your customers look forward to answering your calls again. 

 

For Inbound Calls: Leveraging RespOrg IDs and ALT SPID

While the conversation around phone number ownership and control has historically focused on toll-free numbers, local numbers have largely been left out of the equation—until now. The regulatory framework that has allowed businesses to take authoritative ownership of toll-free numbers through the SMS/800 database has not been available for local numbers in the same way. This limitation left businesses reliant on carriers to control and route their local numbers, unable to break free and manage them independently. 

However, this is changing. NumHub has introduced a groundbreaking solution that brings the same concept of authoritative ownership to local numbers, much like what has been available for toll-free numbers. Through the NPAC (Number Portability Administration Center), which administers local numbers, NumHub enables businesses to claim complete control of their local numbers by leveraging a creative new framework. This framework allows firms to take authoritative ownership of their local numbers, giving them the similar control that toll-free number users have long enjoyed. 

This development is a game changer for businesses. With authoritative ownership and control of local numbers for inbound calls, companies can now directly manage and control their local numbers and can port, route, and secure those numbers based on their needs. By integrating our new framework into the NPAC system, NumHub offers a way for businesses to protect their local numbers from carrier disruptions and fraud, providing a new level of autonomy and security in their telecommunications strategy. 

In short, what was once only possible for toll-free numbers is now a reality for local numbers, thanks to NumHub’s innovative approach. Businesses no longer rely on carriers to control one of their most valuable assets—phone numbers. 

For Outbound Calls: Leveraging Stir/Shaken Certificates

When it comes to outbound dialing, the path to ownership and control of phone numbers takes a different form than inbound services. Instead of relying on RespOrg IDs or ALT SPID codes, businesses can establish ownership and control of their phone numbers through Stir/Shaken certificates. These certificates act as the verification mechanism that ensures the legitimacy of outbound calls, protecting against fraud, spoofing, and unverified caller identities.

NumHub takes a proactive role in this process, serving as an onboarding and vetting agent for the Branded Caller ID (BCID) ecosystem. For businesses making outbound calls, we verify your identity and right to use specific phone numbers before issuing a Stir/Shaken certificate. This certificate authenticates your business as a legitimate caller, ensuring that your outbound calls are trusted by the telecom network and consumers alike.

Stir/Shaken isn’t just a tool for compliance—it is the key to establishing real ownership and control over outbound call traffic. Once your Stir/Shaken certificate is issued, NumHub follows the call path to ensure that the "packets" containing your verified identity travel seamlessly to the terminating carrier. From there, the recipient’s device receives the authenticated call and, in many cases, can even display your business’s logo through Branded Caller ID, further increasing trust and improving call engagement.

Stir/Shaken certificates are the definitive solution for controlling your communications for businesses that rely on outbound dialing. Unlike toll-free numbers, which require a RespOrg ID for authoritative ownership, or local numbers used for inbound calls, which will soon be managed through ALT SPID codes, outbound dialing is secured and controlled via Stir/Shaken. This makes it the third path to ownership and control of phone numbers, enabling businesses to ensure their outbound calls are trusted and verified.

In summary, while inbound calling on toll-free numbers involves establishing ownership through a unique RespOrg ID (and soon, ALT SPID codes for local numbers), outbound dialing uses Stir/Shaken certificates as the mechanism for asserting control and verifying identity. By partnering with NumHub, businesses gain the tools to protect their outbound communications, increase customer trust, and fully control their phone numbers in today’s telecom environment.
