Why is it necessary to register the entity on DLT Platform?

As per the process we SMSINDIAHUB has been made to understand that we have to get all our users registered on whichever telecom operator's connectivity we are using for SMS delivery. For e.g. If we are using Multi operator connectivity like BSNL, Videocon, Vodafone, etc. then all our users have to register on all these operator's DLT Platform. We SMSINDIAHUB also have to register as Telemarketer on all these operator's DLT Platform.

Do I need to pay DLT Registration Fees Rs. 5000+GST (Rs.5900)?

Yes 5900 has to be paid to the telecom operator as DLT registration charge. We are not taking that charge. Also we are getting the entities registered for free whenever the operators are giving us the communication of the same.

If we do not register on DLT platform will our SMS delivery be stopped?

We are connected with multiple operator we will try to pass on the maximum possible flexibility to our esteemed client's, but we SMSINDIAHUB is the aggregator of SMS service wherein we are dependent on the telecom service providers like Vodafone-Idea, Videocon, BSNL, Airtel, MTNL etc. So in case these operators implement the rules strictly as per TRAI mandate then we will be forced to comply with the norms and will not be able to process SMS from Unregistered Entities.

Has the entity to do only company registration on DLT platform?

No. Entity registration is only one of the steps, the Further Phase (2) and Phase (3) includes Header (Sender ID) registration and Content Template Registration respectively, which will be communicated soon.

OTP SMS Services - OTP Authentication API

What is OTP SMS Service?

OTP SMS service involves sending a one-time password to a user’s registered mobile number for authentication purposes. This OTP acts as a temporary, secure code that verifies the user's identity. Typically, OTPs are used in two-factor authentication (2FA) processes, where users must enter both their password and the OTP to gain access to their account or complete a transaction.

The Role of OTP Authentication API

At the core of an efficient OTP system is an OTP Authentication API. This API seamlessly integrates with websites, mobile apps, or other digital platforms to send OTPs in real-time. The API ensures that OTPs are delivered quickly, securely, and with high success rates, minimizing delays or failures that could lead to frustrated users or failed transactions. A good OTP Authentication API supports various messaging platforms and works across global networks, providing an extra layer of security.

Why Use SMS OTP Services?

SMS OTP services are one of the most reliable ways to authenticate users. Here’s why:

High Reach and Accessibility: SMS is supported on all mobile phones, regardless of whether they are smartphones or basic feature phones. This makes SMS OTP an accessible option for users across different demographics.
Quick and Efficient: OTPs are typically delivered instantly, ensuring a smooth and seamless user experience during the authentication process.
Enhanced Security: OTPs are randomly generated and have a short expiration time. This makes them an extremely secure form of user authentication, significantly reducing the risk of fraud or hacking.
Cost-effective: Businesses, especially those in India, find SMS OTP services to be a cost-effective method for securing user data and transactions without the need for complex infrastructure.

Type of OTP SMS Services

In India, OTP (One-Time Password) SMS services are widely used for secure authentication in various industries such as banking, e-commerce, telecommunications, and government services. Several types of OTP SMS services are utilized based on specific needs. Here are the main types of OTP SMS services available in India:

Transactional OTP SMS

Description: These are OTPs sent to users during specific transactions such as online banking, e-commerce purchases, or any financial dealings. Each OTP is unique to the transaction and ensures additional security.
Use Case: Banks, financial institutions, and online retail platforms use this type of OTP for authorizing payments, transfers, and other sensitive actions.
Example: OTP for confirming an online fund transfer or verifying a credit card purchase.

Time-based OTP (TOTP) SMS

Description: In this service, the OTP is valid for a limited time (generally 30-60 seconds). The user must enter the OTP within this time window, adding an extra layer of security.
Use Case: Frequently used for logging into secure accounts, verifying new logins, or resetting passwords.
Example: When logging into an online banking account or payment portal, an OTP is sent that expires after 60 seconds.

Event-based OTP (HOTP) SMS

Description: This type of OTP is triggered by specific events, like login attempts, account changes, or password resets. It remains valid until used, and typically expires after a set number of attempts or if a new OTP is generated.
Use Case: Ideal for applications or services where users don’t need continuous internet access, as OTPs remain valid until used or replaced.
Example: A user receives an OTP after initiating a password reset, valid until they complete the process.

Bulk OTP SMS

Description: This service sends OTPs in bulk to a large user base, especially in cases where multiple users need to authenticate simultaneously. Used by organizations to authenticate many users at once.
Use Case: Popular in large-scale e-commerce sales, digital wallets, or public-sector platforms such as Aadhaar-based services.
Example: Bulk OTPs during a flash sale or in an election process where users need to authenticate to vote digitally.

Multi-factor Authentication (MFA) OTP SMS

Description: OTPs are used in combination with another authentication factor such as a password or biometric verification. The SMS OTP is part of a layered security model.
Use Case: Common in government services, e-governance applications (such as Aadhaar, PAN), and industries where data security is critical.
Example: When accessing e-governance portals like the Income Tax Department’s website, where the OTP is part of a 2-step or multi-factor verification process.

Static OTP SMS

Description: Unlike dynamic OTPs, static OTPs can be valid for an extended period, usually for a session or a specific time window. This method is used in less sensitive situations.
Use Case: Used where there is no immediate risk of data breach, but basic authentication is required, such as low-security websites or apps.
Example: An OTP that is valid for multiple actions within a single session on a lower-risk platform.

Voice OTP Service

Description: Instead of sending an OTP via SMS, the code is delivered to the user through an automated voice call. This method is used as an alternative when SMS delivery fails or for accessibility reasons.
Use Case: Used in situations where SMS delivery might be delayed or inaccessible, such as rural areas or during high network traffic.
Example: A user receives an OTP via an automated call for authentication when a mobile network is congested.

Email-to-SMS OTP Service

Description: In certain cases, OTPs are delivered as an SMS through an email-to-SMS gateway. This allows an organization to generate OTPs via email and send them to users’ mobile devices.
Use Case: Useful when integrating email systems with mobile communication channels for added flexibility.
Example: An OTP is generated on an internal email system and then sent to users as SMS for added security during user verification.

API-based OTP SMS Service

Description: This type involves integrating OTP SMS services into mobile applications or websites using an OTP Authentication API. Businesses can use APIs to automate OTP generation and delivery for secure user login, registration, and transactions.
Use Case: Suitable for enterprises, mobile apps, and websites requiring secure user authentication.
Example: A mobile app that sends OTPs during user login via a seamless API integration.

Flash SMS OTP

Description: Flash SMS OTPs appear directly on the phone's screen and are not stored in the inbox. Once the user reads or uses the OTP, the message disappears.
Use Case: Useful for services where security is paramount, as flash OTPs leave no trace and reduce the chances of the code being intercepted or reused.
Example: An OTP sent by a financial institution for a high-value transaction that doesn’t stay in the phone’s SMS history.

Popular OTP SMS Use Cases in India

Banking and Finance: Banks use OTPs to authenticate login attempts, fund transfers, and high-value transactions. OTPs add an extra layer of security to protect users from fraud.
E-commerce: Online shopping platforms and digital wallets use OTPs to verify payments and validate new user signups.
Telecom: Telecom operators use OTPs for SIM card activations, service changes, or mobile number porting.
Government Services: India’s Aadhaar authentication, income tax filing, and other government services rely heavily on OTP SMS to verify citizens’ identities.
