When building your startup’s tech stack, choosing the right phone number is often overlooked but critical. A poor choice can lead to verification failures, security risks, and operational delays. Here’s what you need to know:
- Real-SIM numbers are the best option for SMS verification. They work with major platforms like Stripe, AWS, and banks, ensuring reliable access and security.
- VoIP numbers (e.g., Google Voice) are great for communication but often fail verification due to being flagged by fraud prevention systems.
- Disposable numbers are risky and unreliable, as they can be recycled or blocked, leading to account access issues.
For a hassle-free experience, use real-SIM numbers for platform verification and VoIP numbers for calls. This dual approach ensures smooth operations and keeps your team connected and secure.
Phone Number Types for SMS Verification
Choosing the right type of phone number for SMS verification can have a big impact on your startup’s operations. Each option comes with its own set of strengths and weaknesses, so understanding them is key to making an informed decision.
Real-SIM Numbers: Reliable and Widely Accepted
Real-SIM numbers are tied to physical SIM cards and operate through traditional cellular networks. This connection to carrier-grade service makes them highly dependable.
The biggest perk of real-SIM numbers is their wide acceptance. Since they look and function just like regular mobile numbers, most verification systems recognize them as legitimate. They work seamlessly with banking apps, payment platforms like Stripe, cloud services such as AWS, and social networks like WhatsApp and LinkedIn.
Another advantage is their long-term reliability. Unlike personal phone numbers, real-SIM numbers often come with features tailored to teams. For instance, verification codes can be accessed by multiple team members through shared dashboards or integrations with tools like Slack. This makes them a practical choice for businesses that need consistent and secure access. Now, let’s see how they compare to VoIP and disposable options.
VoIP Numbers: Great for Calls, Not for Verification
VoIP (Voice over Internet Protocol) numbers rely on internet connections rather than cellular networks to handle calls and messages. Services like Google Voice, RingCentral, OpenPhone, and Grasshopper are popular for business communications.
While VoIP numbers are excellent for handling calls, they fall short when it comes to verification. Many platforms actively block VoIP numbers, using sophisticated detection systems to identify and reject them. For example, trying to verify a Coinbase account or set up Stripe payments with a Google Voice number often results in messages like "This number cannot be used for verification" or "Please use a mobile number."
The issue lies in trust. Verification systems maintain databases of VoIP number ranges, flagging them as unsuitable for secure processes. This makes VoIP numbers unreliable for startups that depend on smooth verification.
Disposable Numbers: Cheap but Risky
Disposable numbers are temporary phone numbers designed for short-term use. They’re often free or very inexpensive, which makes them appealing for quick verification tasks.
However, disposable numbers come with serious risks. Since they’re recycled quickly, you could lose access to critical accounts if the number gets reassigned. Imagine setting up your AWS infrastructure with a disposable number – someone else could later gain control of that number and potentially access your account recovery options.
Another major drawback is platform detection. Many verification systems blacklist known disposable number ranges, meaning these numbers frequently fail verification attempts. For startups dealing with sensitive data or financial transactions, the security risks are especially concerning. A compromised verification number could expose your business to significant vulnerabilities, putting your operations at risk.
Why Real-SIM Numbers Work Best for Startups
Real-SIM numbers consistently outperform VoIP and disposable alternatives, offering a more reliable and secure option for startups. The advantages go beyond technical differences – they directly influence your ability to access essential tools and maintain smooth, secure operations.
Platform Acceptance and Reliability
Major platforms like Google, banks, and Stripe have advanced systems in place to detect and block VoIP and disposable numbers. These platforms maintain comprehensive databases of VoIP number ranges, flagging them as unsuitable for verification.
Real-SIM numbers, on the other hand, operate through physical SIM cards and traditional cellular networks. This ensures that verification codes are delivered promptly and reliably. Their carrier-grade connection makes them indistinguishable from regular mobile numbers in verification systems. This reliability highlights why VoIP numbers often fall short for startups.
When VoIP Numbers Fail Startups
Verification issues with VoIP numbers can lead to significant disruptions. These failures are more than just inconvenient – they can derail operations, especially during critical moments like setting up business accounts.
Take payment platforms, for example. Stripe and similar services reject VoIP numbers for verification due to fraud prevention measures. This can delay your ability to accept payments, potentially postponing product launches.
Banks pose another challenge. Most business banks require SMS verification for account setup and ongoing security measures. VoIP numbers are routinely blocked, forcing startups to find alternatives or face delays in accessing essential financial services.
The problems don’t stop there. Cloud services often reject VoIP numbers, creating operational roadblocks. If your team relies on shared accounts, VoIP verification failures can lock out multiple members, stalling productivity across your organization. Unlike personal phone numbers, which are controlled by one individual, these failures can disrupt your entire team.
Real-SIM Benefits for Team Security
Real-SIM numbers aren’t just about platform compatibility – they also enhance security, which becomes increasingly important as your startup grows. The physical SIM card requirement makes them far more secure than VoIP numbers, which exist only as software configurations and are easier to compromise.
For two-factor authentication, real-SIM numbers ensure reliable delivery of verification codes. They also support secure multi-user access through shared dashboards and integrations, allowing teams to receive codes without sharing personal numbers or compromising security.
Regulated industries, in particular, benefit from real-SIM solutions. These numbers can be registered to your business, ensuring compliance with KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations – something VoIP and disposable numbers simply can’t achieve[1].
Scalability is another key advantage. As your team grows, real-SIM solutions can easily accommodate additional numbers for different departments or functions. This flexibility ensures security and operational efficiency, unlike VoIP options, which often face increased blocking as usage scales.
Nearly 80% of data breaches are tied to weak or stolen credentials[1]. By adopting real-SIM numbers, you’re investing in a secure verification system that safeguards your business accounts and sensitive data from unauthorized access.
How to Set Up a Real-SIM Solution
To get started with a real-SIM solution, you’ll need to evaluate your verification requirements, select a suitable provider, and integrate real-SIM numbers into your existing systems.
Choosing a Real-SIM Provider
When picking a provider, focus on compatibility, team-friendly integrations, and clear pricing.
First, ensure the provider’s platform works seamlessly with the major services your startup relies on. Look for providers offering dedicated numbers that aren’t shared with other users. Shared numbers often face issues like being flagged or rejected by verification systems, which can disrupt your workflow.
Next, check for tools that simplify team collaboration, like webhooks and real-time dashboards. A real-time dashboard allows you to monitor SMS activity across your organization, making it easier to manage and track verification processes.
Transparent pricing is another key consideration. Avoid providers with hidden fees or overly complicated pricing structures. For instance, JoltSMS offers a straightforward $50 monthly flat rate, which includes unlimited inbound SMS (under fair-use policies).
Flexibility in contract terms is also important. Some providers lock you into lengthy agreements, while others offer month-to-month plans. A 30-day minimum commitment strikes a balance, giving you stability without tying you down as your startup evolves.
Finally, consider the quality of customer support. When verification issues arise, having access to dedicated human support can save time and prevent delays in critical processes like account setups or team access.
Once you’ve chosen a provider, the next step is integrating their numbers into your workflow efficiently.
Adding Real-SIM Numbers to Your Workflow
Start by identifying the key areas where verification codes are needed, such as payment processors, cloud services, or banking platforms.
To streamline access, configure webhooks that automatically deliver verification codes to your team’s communication tools. This automation removes the need for manual sharing and speeds up processes, ensuring no delays in accessing critical accounts.
For custom applications or internal tools, API integration is a game-changer. REST API access allows you to programmatically retrieve SMS messages and incorporate them directly into your systems, creating an automated and seamless verification process.
As your team grows, managing access becomes essential. Define clear protocols for who can view the real-SIM dashboard and receive verification codes. Document these procedures to ensure smooth onboarding for new team members and maintain security.
