Defence Research and Development Organisation (DRDO) is the research and development organisation of India’s Ministry of Defence and works through a nationwide network of laboratories, centres and corporate directorates. Its headquarters in New Delhi provides the central administrative setting for policy, coordination, technology management, industry interaction and other organisation-level functions. For researchers, companies, job applicants and members of the public, however, the correct point of contact can vary because recruitment, technology transfer, academic collaboration and media matters are handled by different DRDO units.
DRDO Headquarters is located at DRDO Bhawan on Rajaji Marg in New Delhi. The address is useful for official correspondence, but most visitors and callers should first identify the directorate responsible for their subject. The details below bring together the headquarters address, current official contact routes, email options and practical guidance without confusing the main headquarters with DRDO laboratories, CEPTAM or the Recruitment and Assessment Centre.

DRDO Headquarters Location
DRDO Bhawan is in the central government district of New Delhi, close to the high-security administrative area around Raisina Hill. Because entry conditions can vary by office and purpose, a headquarters address should not be treated as a general public visitor centre.
- Area: Rajaji Marg, central New Delhi.
- Nearby context: the building lies in the central government/defence administrative zone.
- Metro access: Central Secretariat and Udyog Bhawan are practical Metro access points for the wider area; the final leg may require a walk or local transport.
- Security: visitors should carry valid identification and should confirm whether an appointment or entry permission is required before travelling.

DRDO Headquarters Email Id and Online Contact
The most useful DRDO email depends on the subject. The headquarters-level address secydrdo@gov.in is associated with the Secretary, DRDO. For specialised matters, DRDO publishes separate functional email addresses rather than directing every message to one inbox.

- Public interface and media: dpidrdo.hqr@gov.in
- Technical-cadre recruitment (CEPTAM): director.ceptam@gov.in
- Scientific-cadre recruitment (RAC): director.rac@gov.in

How to Reach DRDO Headquarters
- By Metro: use a central Delhi Metro station such as Central Secretariat or Udyog Bhawan and continue towards Rajaji Marg by road or on foot as appropriate.
- By Railway: from New Delhi Railway Station, the Metro or a cab is usually the simplest connection to the central government district.
- By Road: cabs and taxis can use “DRDO Bhawan, Rajaji Marg” as the destination; allow extra time for security-controlled roads.
- Before visiting: confirm the exact directorate, room or appointment details because many DRDO functions are located outside DRDO Bhawan.

When Should You Contact DRDO Headquarters?
- A notice or official communication specifically directs you to DRDO Headquarters.
- You are contacting a headquarters directorate such as industry interface, public interface or a corporate cluster.
- The matter is organisation-level and does not belong to a specific laboratory or recruitment centre.
- You need to send formal correspondence to DRDO Bhawan after identifying the correct recipient or directorate.
Important Points Before Contacting DRDO Headquarters
- Check the DRDO Contact Us page for the directorate connected with your subject.
- Do not send recruitment questions to a technology or media email address.
- Mention the project, vacancy, laboratory or subject clearly in written communication.
- Carry identification and appointment details if an in-person visit has been authorised.
- Use official gov.in or drdo.gov.in contact details and avoid unverified directory numbers.
Frequently Asked Questions
1. Is DRDO Headquarters the same as a DRDO laboratory?
No. DRDO Headquarters is the central administrative and coordinating office at DRDO Bhawan in New Delhi. DRDO laboratories and establishments are separate units located in different cities and work on specialised research areas. A laboratory-specific technical matter should normally be directed to that laboratory rather than to the central headquarters.
2. Where should a candidate contact DRDO about recruitment?
The correct channel depends on the cadre. CEPTAM handles recruitment and assessment for technical and allied cadres, while the Recruitment and Assessment Centre handles scientific recruitment. Candidates should use the contact details given in the relevant advertisement rather than sending a general recruitment question to DRDO Bhawan.
3. Can companies contact DRDO Headquarters for technology transfer?
Yes, but the message should go to the directorate responsible for industry interaction and technology transfer. DRDO publishes separate phone and email details for these subjects. Giving the product, technology or proposal name in the first communication makes it easier to route the enquiry correctly.
4. Can the public visit DRDO Bhawan without an appointment?
DRDO Bhawan is a government defence establishment, not a general tourist or public-service centre. Entry can be controlled and purpose-specific. Anyone who genuinely needs to visit should contact the relevant office first, confirm whether a personal visit is required and follow the security and identification instructions provided.
5. What information should be included in an email to DRDO?
State your full name, organisation if applicable, the exact subject of the enquiry and the DRDO unit or notice concerned. For recruitment, include the advertisement or post reference. For technical or industry matters, describe the technology or proposal briefly and attach only relevant documents requested by the concerned office.
