Most people visit TSB Online only to check their balance or download a statement. But before you even log in, there’s one warning from the Kerala Treasury Department worth remembering — they will never call asking for your OTP or password. If someone does, it’s a scam, and treasury-impersonation calls target account holders often enough that this is worth knowing before anything else in this guide.
TSB Online itself is Kerala’s Treasury Savings Bank system — it’s been around for over 50 years, running savings and fixed deposit facilities directly through the state’s Treasury Department rather than through a commercial bank. Portal is tsbonline.kerala.gov.in, login needs your username, password and captcha, and the helpline is 1800-4255-176 (toll-free) or 0471-2322712. No hidden charges on transactions either, including internet banking transfers.
Account Types: TSB vs PTSB vs ETSB vs TFD
A common mistake is treating “ETSB” as just another name for TSB online banking in general. It isn’t — it’s a specific, separate account type, and which one you hold decides your login and what features you’ll see:
| Account Type | Who Can Open It |
|---|---|
| TSB (Treasury Savings Bank) | Any individual |
| PTSB (Pensioners TSB) | Exclusively for pensioners |
| TFD (Treasury Fixed Deposits) | Any individual |
| ETSB (Employees TSB) | Exclusively for state government employees |
These aren’t interchangeable. If you’re not sure which one you have, check your passbook rather than guessing. Registering under the wrong type is one of the more common sources of confusion for first-time users, and if you’re logging in for the first time after opening the account, this is probably the first thing worth verifying.
TSB Online Login — Step by Step
Open the TSB Online portal and click Login. Enter your username, password, complete the captcha, and sign in. Once you’re inside, you’ll see options like Account Statement, Fund Transfer, Beneficiary Details, Return A/C Correction, Settings and Logout. Fairly standard dashboard layout, nothing unusual there.
TSB Online New User Registration
Head to tsbonline.kerala.gov.in/new-user-registration and enter your TSB, ETSB, PTSB or TFD account number along with your registered mobile number. Pick a username (lowercase letters and numbers only), hit Next, and an OTP lands on your mobile. Enter that, and if it’s a joint account, the OTP goes to all joint beneficiaries rather than just the primary holder — worth confirming this still matches current portal behaviour before you rely on it, since these operational details do get updated occasionally. Once verified, a temporary password arrives on your phone and you’re set.
One thing that surprises many first-time users: registration fails immediately if your mobile number doesn’t match treasury records, and unlike a lot of banking apps, there’s no option to just update it online. If you’ve never used the portal before, don’t worry if the registration screen looks a little confusing the first time; most people get through it in a few minutes once the account type is clear. But if the number’s wrong, you’ll need to visit your local office first with KYC documents, then come back and register once that’s sorted.
TSB OTP Scam Warning — What Treasury Officials Will Never Ask
The department has put out an explicit public notice on this: officials will never call asking about your deposits, pension details, or request your OTP over the phone. They never ask for this information over the phone, no exceptions.
Get a call like that, don’t engage. Don’t confirm anything, don’t share anything, just hang up and call your local office or the toll-free helpline yourself at 1800-4255-176 or 0471-2322712 to report it.
Beyond that specific scam pattern, the basics still apply. Don’t share your user ID, login password, transaction password or OTP with anyone, skip public Wi-Fi for account access, and log out properly on shared computers. Unauthorized transactions are a punishable offence, so these aren’t just suggestions.
Fund Transfer, Transaction History and Forgot Username
Fund transfers happen either within the TSB network directly, or out to other banks via IMPS/NEFT — both are on the dashboard along with a transaction history you can pull up any time.
Forgot your username? tsbonline.kerala.gov.in/forget-username asks for your account number and registered mobile, sends an OTP to verify, and texts your username back to you. Quick fix, no branch visit needed for that one.

If you remember just one thing from this guide, make it this: never share your OTP or password with anyone claiming to call from the treasury. Most other issues — whether it’s a forgotten username or a registration problem — can usually be resolved through the official portal or your nearest local office. For related Kerala government services, the Kerala Registration Department guide covers property registration, a separate system from this treasury-banking setup.
