TSR Darashaw — now operating as Computershare Investor Services Pvt Ltd — is one of India's oldest and most respected registrar and transfer agents. If you hold shares in a Tata group company or another company that uses Computershare as its RTA, this guide explains how to contact them, update your KYC, initiate transmission, and resolve common investor problems.

TSR Darashaw & Co. Ltd was established in Mumbai in 1948, making it one of India's oldest share registry firms. The name itself was a combination of the founding surnames — the firm built its reputation handling the secretarial and share registry work for some of India's most prominent industrial houses, especially the Tata group.
Over the decades, TSR Darashaw grew into a full-service registrar and transfer agent, handling dividend payments, share transfers, KYC updates, demat conversion, and investor correspondence for a large portfolio of listed companies. By the time SEBI tightened RTA regulations in the 2000s and 2010s, TSR Darashaw was already one of the top-ranked RTAs in the country by investor base size.
Computershare Limited — an Australian publicly listed company headquartered in Melbourne — is the world's largest share registry and investor services company. It operates in over 20 countries. Computershare acquired TSR Darashaw and rebranded the Indian operations as Computershare Investor Services Private Limited. The Mumbai office, the investor service processes, and the staff largely remained the same — what changed is the corporate identity and the global governance framework behind the operations.
For investors, the practical implication is straightforward: if your share certificate or annual report says "TSR Darashaw" as the RTA, the entity you now deal with is Computershare India. The office has moved from the older Mahalaxmi address to C-101, 247 Park, L.B.S. Marg, Vikhroli West, Mumbai 400083. Their website is computershare.com/in.
Computershare India handles the share registry work for a significant number of Tata group companies. This is a legacy of the historical relationship between TSR Darashaw and the Tata conglomerate going back decades. The companies listed below have historically used TSR Darashaw / Computershare as their RTA — but you should always verify the current RTA from the company's latest annual report, because RTAs do change occasionally.
| Company | Exchange / Sector |
|---|---|
| Tata Consultancy Services (TCS) | BSE / NSE — IT Services |
| Tata Steel Ltd | BSE / NSE — Steel |
| Tata Motors Ltd | BSE / NSE — Automotive |
| Tata Power Company Ltd | BSE / NSE — Power |
| Tata Communications Ltd | BSE / NSE — Telecom |
| Titan Company Ltd | BSE / NSE — Consumer |
| Voltas Ltd | BSE / NSE — Engineering |
| Trent Ltd | BSE / NSE — Retail |
| The Indian Hotels Company Ltd (Taj Hotels) | BSE / NSE — Hospitality |
| Rallis India Ltd | BSE / NSE — Agrochemicals |
Computershare India also serves a number of non-Tata companies. The list above covers the most commonly searched companies — particularly because many retail investors received TCS or Tata Steel shares through allotments, ESOPs, or inheritance and have held them in physical form for years.
How to verify: Open the company's latest annual report and go to the section titled "Registrar and Share Transfer Agent" or "Corporate Information." The RTA name, address, and contact details are always listed there. You can also check the company's investor relations page on its website.
There are three reliable ways to confirm this:
If you're unsure which company your physical certificates belong to — for example, you've inherited shares and the certificates are old — read the distinctive numbers and folio number off the certificate face. These can be used to trace the company through the BSE or NSE corporate filings.
The current office address is:
Some older correspondence and share certificates still carry the previous address: 6-10, Haji Moosa Patrawala Industrial Estate, 20 Dr. E Moses Road, Mahalaxmi, Mumbai 400011. Documents sent to that address are typically forwarded, but it is better to address your courier to the Vikhroli West address going forward.
Computershare India publishes its investor helpline number and email address on its official website at computershare.com/in under the "Contact Us" or "Investor Services" section. These details also appear in every annual report of the companies it serves. Because contact numbers and email IDs do change periodically, I recommend you pull the latest details directly from the website rather than rely on a number printed here.
For urgent matters — especially transmission or loss of certificates — it is always better to send a written letter by courier to the Vikhroli office with acknowledgement due. Email works for routine queries, but for anything that involves submission of original documents, physical courier is the standard process.
SEBI's mandatory KYC update requirement applies to all physical shareholders. If you hold shares of TCS, Tata Steel, Titan, or any other company whose RTA is Computershare India, you need to submit your KYC details using the ISR form set. This is not optional — SEBI has made it clear that companies and RTAs must freeze transfers and dividend payouts on folios where KYC remains incomplete.
| Form | Purpose |
|---|---|
| ISR-1 | Name correction / PAN update / contact details update |
| ISR-2 | Bank account update / ECS mandate for dividend |
| ISR-3 | Signature update / specimen signature registration |
| ISR-4 | Nomination (addition, change, or cancellation) |
All four ISR forms can be downloaded from computershare.com/in or from the SEBI investor education section at sebi.gov.in. The company's investor relations page also typically has them linked.
If your shares are in demat form, KYC updates like bank account and address changes can also be done through your Depository Participant (DP). Your DP will update the details in the CDSL or NSDL system, which flows through to the RTA records.

If you hold physical share certificates of TCS, Tata Steel, Tata Motors, Titan, or any other Computershare-registered company, you must convert them to demat before you can sell. Physical transfers of listed shares have been banned since April 2019. You cannot transfer listed physical shares from one person to another in physical form — the only exception is transmission (inheritance), and even that results in re-materialisation followed by demat conversion.
If a certificate is lost or torn, the process becomes more complicated. You'll need to apply for a duplicate certificate first before initiating demat conversion. See our guide on lost share certificate assistance for the full process.
If you want help converting physical shares to demat form, our team handles the document preparation and submission tracking. Visit our physical shares to demat service for details.
Transmission means transferring shares from a deceased shareholder's folio to the legal heir or nominee. If the person who passed away held TCS, Tata Steel, Tata Motors, Titan, or any other Computershare India-registered company's shares, you will need to file a transmission request with Computershare India directly.
Where a nomination exists and was registered with Computershare India or the company during the shareholder's lifetime, the process is considerably simpler — the nominee needs only submit the transmission form, death certificate, identity proof, and bank details. SEBI has now specifically mandated that companies honour registered nominations without requiring succession certificates up to Rs 15 lakh face value (this threshold was revised — always check the latest SEBI circular at sebi.gov.in for the current limit).
SEBI regulations require RTAs to process a complete transmission request within 30 days. If Computershare India finds any document deficiency, they will send you a deficiency letter and the 30-day clock restarts from the date you resubmit. For this reason, it is important to get the full document set right the first time.
Once transmission is processed, shares of TCS, Tata Steel, or other Computershare-registered companies will be credited to the claimant's demat account (if the request included a demat account number) or a new physical certificate will be issued in the claimant's name.
If you need help managing the transmission process, including document preparation, our team has handled hundreds of these cases. Visit our share transmission to legal heir service page for full details.
If you hold TCS, Titan, or Tata Steel shares and haven't been receiving your dividend credits, the most common reasons are an outdated bank mandate in the folio, a closed bank account, or an incorrect address for dividend warrants. All of these are fixable through a KYC update with Computershare India.
Submit Form ISR-2 with a cancelled cheque from your current bank account. The cancelled cheque must have your name pre-printed on it, or you can alternatively submit a bank letter certifying your account details. Send this to Computershare India's Vikhroli office along with a covering letter mentioning your folio number and company name.
TCS, Tata Steel, Tata Motors, and Titan company dividend histories are published on the respective company's investor relations pages and in their annual reports. You can also see the dividend payment history in your demat account statement if shares are in demat form. For physical folios, Computershare India can provide a folio statement on written request.
Dividends that remain unclaimed for 7 years from the date of declaration are transferred by the company to the Investor Education and Protection Fund (IEPF) Authority. The corresponding shares are also transferred to the IEPF demat account. This is a mandatory statutory requirement under Section 124 and 125 of the Companies Act 2013.
If your TCS, Titan, or Tata Steel dividends have been transferred to IEPF, the process to recover them involves filing Form IEPF-5 online. See the next section for how this works specifically for Computershare-registered companies. For general guidance on recovering unclaimed dividends, visit our unclaimed dividend recovery service page.
If shares of TCS, Tata Motors, Tata Steel, Titan, or any other Computershare India-registered company have been transferred to the IEPF Authority — because dividends went unclaimed for 7 or more consecutive years — here is how the claim process works.
For cases where shares went to IEPF more than 10 years ago, or where original certificates are not available, the process can be more involved. Our team has handled IEPF claims for TCS, Tata Steel, and Titan shareholders specifically — visit our IEPF claim assistance service for help.
Name mismatches are very common among investors who hold shares of Tata group companies allotted in the 1990s or early 2000s. At that time, name spellings in company records were often keyed in manually and errors crept in. The shareholder's name on the certificate might say "Rajesh Kumar" while the PAN card says "Rajesh Kumar Sharma" — or an initial is missing, or a surname appears as a middle name.
These mismatches need to be corrected before you can do anything else — demat conversion, transmission, or sale. The process uses Form ISR-1.
Send the complete set by trackable courier to Computershare India, C-101, 247 Park, L.B.S. Marg, Vikhroli West, Mumbai 400083. Retain photocopies of everything you send, including the original certificates.
Name corrections typically take 30 days. If Computershare India needs clarification, they will send a query letter. We recommend attaching a clear covering letter explaining exactly what the issue is and what correction is needed — it speeds things up considerably.
If you need help preparing the ISR-1 submission and supporting documents, see our share name correction service.
Most investor problems with TSR Darashaw / Computershare India fall into a few categories: delayed responses, rejection of documents without clear explanation, or no communication after submission. Here is how to handle each situation.
Send a follow-up letter by registered post to Computershare India's Vikhroli office, clearly stating your original submission date, the courier tracking number, and the specific request (KYC / transmission / demat). Address it to the "Head — Investor Services." Keep a copy.
Computershare India is required to send a deficiency letter specifying exactly what is missing or incorrect. If the rejection letter is vague, write back asking for a specific clarification. If you still do not get a satisfactory answer within 15 days, escalate.
If Computershare India does not resolve your grievance within 30 days, file a complaint on SEBI's SCORES portal at scores.gov.in. SCORES stands for SEBI Complaints Redress System. Filing here puts the complaint on SEBI's radar and requires the RTA and the company to respond within a stipulated timeframe. This is the most effective escalation route for unresolved investor complaints against RTAs.
When filing on SCORES, select the company name (e.g., Tata Steel or TCS) — not the RTA name. The complaint routes to both the company and the RTA. You will need to register on SCORES first with your PAN and email ID.
Each listed company has a Compliance Officer or Company Secretary who is designated to handle investor grievances under Regulation 6 and Regulation 13 of SEBI's Listing Obligations and Disclosure Requirements (LODR) Regulations. Their contact details are on the company's website under "Investor Relations." Writing to the Company Secretary directly — especially for TCS or Tata Steel, where the corporate governance teams are known to be responsive — can move things faster than waiting for Computershare India alone.
Companies occasionally change their RTA. While Computershare India has been the long-standing RTA for Tata group companies, it is always worth verifying before sending documents. A misrouted courier to an old RTA address is a common cause of delays. Always check the latest annual report or the company's website before sending anything.
