Quick answer

You can get your new TC (Tax/Building) number for Thiruvananthapuram (Trivandrum) Corporation from:

  1. Thiruvananthapuram Municipal Corporation office (ward office / corporation building)
  2. Online property‑tax portal via Kerala LSGDept:
  3. Building‑tax / property‑tax section of the Corporation (in person or via e‑district/common service centres)

What “TC number” means here

In Thiruvananthapuram Corporation, TC number is the identifier used in the property/building tax system (often printed on tax notices, building certificates, and house plates). The Corporation periodically revises and re‑allocates TC numbers —for example, during property‑tax revision drives—so older documents may show an old number while newer ones show a new TC number.

Where to get the new TC number

1. Corporation office (Ward Office / Tax Section)

  • Visit the Thiruvananthapuram Municipal Corporation office or your ward office.
  • Go to the Building Tax / Property Tax section.
  • Provide:
    • Your old TC number (if known)
    • Property address / survey number
    • Ownership proof (Aadhaar, title deed, previous tax receipt, etc.)
  • They can:
    • Tell you the new TC number
    • Issue a building certificate / tax memo showing it
    • Sometimes arrange a metal plate with the new number to be affixed on the house

2. Online property‑tax portal (Kerala LSGDept)

Kerala’s Local Self Government Department runs a statewide property tax portal that Thiruvananthapuram Corporation uses:

  • On the portal you can usually:
    • Search by old TC number / property ID / owner name
    • View current property tax record , which should show the current TC number
    • Download / print tax demand notice or assessment summary where the new TC number appears

If the portal shows an updated assessment after a re‑enumeration drive, that’s effectively your new TC number.

3. E‑District / Common Service Centres (CSC)

If you don’t want to go to the Corporation directly:

  • Visit a nearby Akshaya Centre / CSC or e‑District facilitation centre in Thiruvananthapuram.
  • Ask them to:
    • Pull up your property tax record on the LSG property‑tax system
    • Print the latest tax memo / assessment showing the TC number

They usually charge a small service fee but can save you time navigating government offices.

If you’re specifically looking for “newly changed” TC numbers

During past revision exercises, the Corporation:

  • Completed new TC allocations ward by ward (e.g., 98+ wards in one earlier cycle)
  • Displayed new TC numbers on metal plates on houses
  • Issued residence certificates with the new TC number so people could update other documents (Aadhaar address, bank records, etc.)

If you suspect your TC number changed but you haven’t been informed:

  1. Check the latest property tax notice you received (physical or online).
  2. Look for a metal plate on your house (often installed by the Corporation during re‑numbering).
  3. If still unclear, go to the ward office with your old documents and ask for the current TC number in the system.

Practical steps (step‑by‑step)

  1. Gather documents
    • Old tax receipt / TC number
    • Property deed / patta
    • Aadhaar / ID proof
  2. Try online first
  1. If online doesn’t match or you see two numbers
    • Go to Thiruvananthapuram Corporation / your ward office
    • Ask for the current TC number in the property‑tax system and a printout / certificate showing it.
  1. Update your records
    • Use the new TC number on:
      • Future tax payments
      • Building applications
      • Address proofs (if advised by the Corporation)

TL;DR

  • Primary source : Thiruvananthapuram Municipal Corporation (ward office / building‑tax section).
  • Online source : Kerala LSG property‑tax portal (http://lsgkerala.gov.in/ml/propertytax).
  • Alternative : Akshaya/CSC/e‑District centres that can access the same property‑tax system.

All of these will show or issue your new TC number as recorded in the Corporation’s current property‑tax database.
