But first, a short chatter about OTP wouldn’t hurt.

What is OTP?

OTP is a 4-6 numeric or alphanumeric code with a single-use specific function for a particular session/authentication. 

A young man logging in with an OTP code received from SMSCountry

In today’s age, it is pretty normal to have a double-factor authentication or even a multi-factor authentication. It ensures an added layer of security and prevents fraud and security theft. 

OTP was developed to serve the singular purpose of providing authentication and verifying users. It is used in quite a few businesses to maintain a secure and safe user flow

OTP is usually sent via an SMS, and they tend to expire after a certain amount of time – generally after 10 minutes.

So as a business, you need to ensure that your customers instantly receive their OTPs and can log in/authenticate smoothly. For this, you need to choose an OTP SMS service provider with the best services. 

You can use an OTP service provider’s voice or SMS OTP verification service.

What is an OTP service provider?

An OTP service provider is any company or platform that helps you deliver OTPs to customers. 

The service provider may use SMS, email, or mobile apps. OTP service providers help businesses improve security by adding an extra layer of authentication to protect user accounts and sensitive information.

What features should I look for in an SMS OTP provider?

Here are the nine features you should look out for in an SMS OTP provider.

  • Delivery speed and reliability: Reliability measures the percentage of outgoing SMS OTP that reach their intended destination. On the other hand, delivery speed measures the time between sending and receiving the SMS OTP. Both metrics offer valuable information on the deliverability of SMS OTP.
  • High delivery rates: High delivery rates ensure your customers receive SMS OTP as soon as possible. Technically a 100% delivery rate is unachievable. Look for a rate as close to 100% as possible.
  • High-level security features: Security features like single-time or time-limited use give SMS OTPs an edge over email authentication. SMS OTPs also give you an additional layer of security when used with passwords.
  • Compliance with relevant regulations: Choosing SMS providers that mind compliance helps you abide by the laws of the land. Refer to your local regulatory body to learn about the general laws and regulations. Then ask your SMS provider how they apply them.
  • Two-factor authentication: 2FA helps you secure your accounts by adding an additional layer of verification. Single-step verification can be hacked into, so having 2FA via SMS OTP is essential.
  • Integration with third-party applications: OTPs are autogenerated. An OTP service provider that easily integrates with other applications makes life easy for you.
  • Customer support: You will not be able to figure it all out by yourself. You will need to connect with your SMS provider when you hit a roadblock. A 24/7 support structure in addition to a knowledge base that you can refer to is ideal.
  • Transparent pricing: While most pricing is displayed on websites, some cost structures may be hidden, like recurring monthly costs. These can significantly impact your operational costs.
  • Flexible billing options: Compared to a fixed billing option, a flexible option lets you pay for the consumption. Look for pay-as-you-go options with SMS providers. This will drastically reduce your operational costs.

TeleSign – best for high-risk applications

TeleSign is a well-known OTP company that focuses on 2-factor authentication services. Their prime area of focus is social media websites that allow users to have added security to their accounts. 

They also offer patented phone-based verification and two-factor OTP authentication services. These services are undertaken using time-based OTPs that are either sent via SMS or voice messages

 Best otp service provider | Telesign customer waiting for an OTP

We also found that TeleSign offers digital identity and programmable communication services that range from PhoneId, integrable voice calling, and rich communication services. 

Features of Telesign

TeleSign offers trust as its premiere product. Through a suite of verification services like call OTPs and SMS OTPs with varying levels of protection, Telesign offers to protect its customers from fraud and deception.

The service employs multi-factor authentication and routes for OTPs. It also offers risk assessments to detect fraud before it’s too late.

How does this product work?

It’s either Telesign has some countries restricted in their service offering, or they still have some work to do with making it easy for you to signup for their services.

When you signup for the product, you can expect some hurdles. For example, when my team and I tried signing up for Telesign, we couldn’t verify our number. 

Though their customer support team responded to our query.

When we finally logged in, we still could not fire up an OTP. 

Pros of TeleSign

  • More focus on 2-factor authentication
  • Delivery is adequate 
  • Pricing is nominal 
  • Immediate response from the Support team.
  • Available in 230+ countries

Cons of TeleSign

  • Number validation is a bit poor 
  • Pricing is not as flexible as advertised
  • Some numbers and countries are not supported by the system despite them being on the list.
  • Substantial delay in receiving OTPs.
  • Free trials are difficult to get started.

TeleSign Pricing

TeleSign offers custom pricing. You can get more information after filling a contact form.

According to the reviews by other organizations and the claims on their website, TeleSign’s main product is geared towards building trust and removing fake users. 

They have employed high-level security features and ensure compliance with regulations across the board. This means an additional layer of security in the form of 2FA too. 

However, the same security features seem to have created issues with deliverability of OTP SMS. Additionally, it is difficult to find TeleSign’s pricing anywhere across the web. Although they have a very supportive customer support team- the system is inaccessible to trial users.

SMSCountry provides all you need to delight your customers with fast and secure OTP SMS. At the best price

2Factor– best for small organizations

 Best otp service provider | A businesswoman searching for OTP Service providers

Their OTP service is quite reliable and offers text-based and voice-based services. They also have an extensive reporting and analysis tool that allows users to adjust their campaigns.

Features of 2Factor

One of the unique features offered by 2Factor is Voice OTP. You receive a phone call relaying the OTP code. 2Factor also offers Transactional SMS APIs and Promotional SMS APIs.

Each SMS has twice the chance of going through the system with fail-over handling, which re-routes failed messages through backup operators. 2Factor also claims not to resell customer data to any third party.

How does this product work?

So naturally we wanted to take a look at this product too. We signed up for a trial account, and the option was displayed on the home screen.

 The trial sign-up page did not ask for a ton of information. The product dashboard is fairly simple.

top otp service providers | 2Facor dashboard all the option offered by 2Factor



The dashboard is fairly straightforward, with all the options laid out flat on the screen. 

2Factor offers SMS APIs to send and verify OTPs. You can auto-generate 4-6 number OTPs or set a limit to the number of digits you want the system to work with.

Pros of 2Factor

  • Reliable OTP delivery
  • A2P messaging.
  • Pay per OTP delivery only.
  • API for sending OTPs, transactional SMS and promotional SMS.
  • Manage your DLT and reseller accounts from one dashboard.

Cons of 2Factor

  • OTP delivery may take time
  • The UI/UX of the web app is basic and simple.
  • 2Factor is available for the Indian market only
  • Insufficient documentation to seamlessly connect the user from the dashboard to the API.
  • Low social media presence which makes it harder to find the brand despite its simplicity.

Customer Testimonials

Although this product was simple and well-developed, it was hard to find reviews online for them.

One reason for this may be their very low social media presence. Another reason may be the users are not impressed with the actual product. 

Either way, 2Factor has some work cut out for them. 

2Factor Pricing

2Factor offers OTP message packs. You can purchase a minimum of 5000 SMS OTPs at INR 0.28+ tax and up to 1,000,000 OTPs at INR 0.15+ tax. You also get a trial pack of 2000 OTPs.

For Voice OTPs 2Factor charges a flat INR 0.34+ tax. You can also purchase 1000 Voice OTPs for a free trial of the service.

2Factor accepts payments via Instamojo.

Being a local solution, 2Factor’s focus is very niche. By offering only one service-bulk SMS, 2Factor is able to offer fast and reliable OTP delivery, good customer support, compliance with local regulations, 2FA and transparent pricing. But 2Factor lacks third-party integrations and high-level security features.

How to choose an OTP provider? 

Many voice and SMS OTP service providers in the market are ready to offer their services. But how do you find the right provider? 

Here are a few things you can take into consideration before choosing a provider: 

  • OTP delivery speed should be quite fast ( < 10 seconds) 
  • Uptime should be close to or more than 97% 
  • A 24/7 customer service 
  • Number validation as a service should work efficiently 
  • Global presence of the provider 

Also, do you want a domestic or international OTP service provider?

Ensure that you consider these when trying to choose your OTP service provider for your business and OTP needs. 

Follow these steps.

Step 1: Determine your OTP requirements

 Consider factors such as the number of OTP messages you need to send per month, the geographical coverage required. Also see if you have any specific needs, such as message personalisation or scheduling.

Step 2: Research potential providers

Look for providers that provide the nine features explained in the previous section. Sift through reviews, comb through company websites, and gather information about services, features, and customer feedback

Step 3: Check delivery rates

You want to choose a provider who consistently delivers your OTP without delays or failures. Look for providers with high delivery rates. Also, check their claims and see what measures they take to ensure message delivery.

Step 4: Evaluate security

Ensure your SMS service providers have robust security measures to protect your data and prevent unauthorized access. Look for features such as encryption, secure API connections, and compliance with data protection regulations

Step 5: Check customer support

Having reliable customer support can be crucial, especially when you encounter issues with SMS campaigns. Check your provider’s customer support through various channels like phone, email, or live chat. Look for providers that provide support during your business hours and have a reputation for helpful and prompt customer service.

Step 6: Evaluate pricing

Consider your budget and then evaluate the pricing models of all your shortlisted bulk SMS service providers. Look for hidden pricing. Also pay attention to factors such as message volume discounts, contract terms, and any limitations or restrictions that may affect your usage and cost.
