How to Add the 2s.ms Domain for TRAI Compliance SMS Campaigns in Cuttly

Important Notes: Responsibility for Compliance: Users are responsible for registering their HEADER and static URL with TRAI's DLT platform. Cuttly simply provides the tools to manage the shortened links in the 2s.ms domain and is not responsible for sending SMS messages or ensuring registration with TRAI. Cuttly does not manage SMS delivery or the content of your messages. The platform only provides the URL shortening tool to create links that comply with TRAI's guidelines.


The domain 2s.ms is publicly available solely for shortening links with HEADERs, in response to the implementation of the Telecom Regulatory Authority of India (TRAI) regulations. Cuttly has developed this Generic SMS Shortener to comply with TRAI's SMS regulations, ensuring that shortened URLs meet the character limit restrictions, leaving users with maximum space for the link alias or unique short link ID.

How the 2s.ms Domain Works: The 2s.ms domain is added like any other custom domain in Cuttly, but with the requirement to include a HEADER in the format: 2s.ms/HEADER, where HEADER represents your unique SMS header, as required by TRAI.

To use 2s.ms/HEADER, you need at least a Single subscription, and follow these steps:

1. Log in to your Cuttly account.

2. Go to the Edit Account section to manage domains.

4. Enter the domain in this format: 2s.ms/HEADER/, where "HEADER" is your SMS header that complies with TRAI. The HEADER is a 6-character identifier assigned to you by TRAI's Distributed Ledger Technology (DLT) platform.

5. Accept the declaration that you are responsible for compliance with TRAI regulations and click Add New Domain.

6. No additional DNS or TXT settings are required, as the domain automatically configures itself. Simply wait for approval.

7. You can add multiple instances of 2s.ms/HEADER/ if you need to use several HEADERs for different campaigns.

8. Once approved, you can start shortening links in the 2s.ms domain, combined with your HEADER, ensuring full compliance with TRAI regulations.


Benefits of Using the 2s.ms Domain:



The 2s.ms domain offers a significant advantage for SMS campaigns due to its shortened format, fully compliant with TRAI regulations. The maximum length of a link under the TRAI's 30-character limit must include https:// at the beginning.

The full link format https://2s.ms/HEADER/ uses 21 characters, leaving 9 characters for the dynamic part (alias) of the short link, which is ample for generating unique and concise URLs.

By using 2s.ms, businesses can streamline their SMS campaigns, comply with TRAI's strict regulations, and optimize the space for their short links. For TEAM plans:

If you need more flexibility in managing headers and 2s.ms domain, consider upgrading to a TEAM plan.
