Login Verification Code SMS Template for IT & Software Companies
A ready-to-adapt SMS message for IT services firms, SaaS and software companies, with placeholders, sample values and compliance notes.
When to Send This Message
Send for two-step verification at login. For IT services firms, SaaS and software companies, this is one of the everyday messages that keeps users and clients informed without a phone call. It can be sent manually from a panel at first and automated later through an API.
For SaaS products, onboarding, usage alerts, billing and security notifications are everyday communication, and they must be reliable.
The SMS Template
India (DLT format)
{#var#} is your [Business Name] verification code. It expires in 10 minutes. Do not share this code with anyone.International (plain text)
{otp} is your [Business Name] verification code. It expires in 10 minutes. Do not share this code with anyone.Example with sample values
930184 is your [Business Name] verification code. It expires in 10 minutes. Do not share this code with anyone.
With these sample values the message is 113 characters in the standard GSM-7 character set, which is 1 SMS part (square brackets count as two characters each). Long links or local-language (Unicode) text increase the count, as Unicode SMS allow 70 characters per single part.
Replace [Business Name] with your registered brand name. Links shown use example.com as a placeholder; use your own domain.
Placeholders and Sample Values
| Placeholder | Meaning | Sample value |
|---|---|---|
| {#var#} | Otp | 930184 |
Filling in each placeholder
- Otp (sample: 930184): Generate a fresh random code for each request; 4 to 6 digits is typical.
This template has 1 placeholder and a body of 110 characters before values are filled in. Shorter messages cost less and are more likely to be read in full; aim to keep the filled-in message within one or two SMS parts.
Category and Approval
OTP messages are registered for one-time passwords only. Keep them short, state validity, and warn the customer never to share the code. Do not mix OTPs with any other content.
Compliance Checklist
- The header (sender ID) and the template are registered on a DLT platform, and the template text matches exactly, apart from the variables.
- Each {#var#} holds only the kind of value it was registered for; most platforms limit each variable to 30 characters.
- Any link uses a domain whitelisted for your header, as TRAI requires for URLs in commercial SMS.
Rules to keep in mind for IT & Software Companies
Security messages (OTPs, login alerts) must never contain marketing content. B2B outreach must respect privacy laws in each market, such as GDPR for EU contacts and CAN-SPAM or TCPA in the US, as well as the DPDP Act, 2023 in India.
General guidance, not legal advice. Rules change, so confirm current requirements before launch. See our SMS compliance guide for India.
Tips for Better Results
- Rate-limit OTP requests to protect against abuse and unnecessary costs.
- Generate a new random code for each request and expire it quickly.
