Why TNREGINET OTP Is Not Coming

Here are the most common reasons.

1

Weak Mobile Network

Poor signal can delay SMS delivery.
Move to an area with better network coverage and request the OTP again.

2

Server Busy Issue

TNREGINET servers may become slow during peak hours.
This usually happens in the morning, lunch time, or near registration deadlines.
Try again after some time.

3

Wrong Mobile Number

The OTP only goes to the registered number linked to your TNREGINET account.
If your old number is inactive, you may not receive the OTP.

4

Browser Problems

Old cookies or browser extensions may block login requests.
Using Incognito Mode often helps.

5

Multiple OTP Attempts

If you request OTP many times quickly, the system may temporarily block new requests.
Wait at least 15 minutes before retrying.
