TextLocal vs StartMessaging: OTP API Comparison for India

TextLocal is a long-standing name in Indian SMS. If you’re evaluating it specifically for OTP and phone verification use cases, here’s how it compares to StartMessaging in 2026.

TL;DR

• TextLocal is a general-purpose bulk SMS API that requires DLT registration and where you build the OTP logic yourself.
• StartMessaging is OTP-first with a dedicated verify endpoint, no DLT paperwork, and Rs 0.25 per OTP.

Pricing

TextLocal’s public pricing is credit-based and varies with prepaid volume; transactional SMS lands in the Rs 0.18–0.30 per SMS range for most customers. StartMessaging is flat Rs 0.25 per OTP on a pay-as-you-go INR wallet with no minimum top-up.

DLT and Compliance

TextLocal complies with TRAI by requiring you to register on the DLT portal and submit headers and templates. That’s the right approach for large enterprises with a compliance team, but it adds 1–3 weeks of onboarding for startups.

StartMessaging’s standard route is DLT-free — we hold the principal entity registration on your behalf and route OTPs through pre-approved templates.

OTP-Specific Features

APIs and Documentation

TextLocal’s SendSMS API is a single endpoint with query parameters; you’ll generate OTPs and verify them in application code. StartMessaging splits the flow into /otp/send and /otp/verify, returning a requestId you store instead of the code itself.

When TextLocal Wins

• You need bulk promotional SMS, not just OTPs.
• You already have DLT registration approved.
• You want a long-standing enterprise vendor backed by Cisco.

When StartMessaging Wins

• You want phone OTP shipped today without DLT paperwork.
• You want a real verify endpoint instead of building it yourself.
• You want pay-as-you-go INR billing with no minimum commit.
