Aadhaar is India’s biometric-based digital identity system administered by the Unique Identification Authority of India (UIDAI), a statutory authority under the Government of India. UIDAI manages Aadhaar enrolment, updates, authentication, verification and the national technology infrastructure that supports Aadhaar services. People often search for an ‘Aadhaar head office’ or ‘Aadhar card head office phone number’ when an enrolment, update, PVC card or authentication issue remains unresolved. The correct national headquarters is the UIDAI Head Office in Gole Market, New Delhi. However, citizens normally do not need to visit the headquarters for routine Aadhaar work. UIDAI provides the toll-free 1947 contact centre, online services, Aadhaar Seva Kendras and regional/state offices. The details below give the official head-office address and explain when to use 1947 instead of writing to New Delhi.

Aadhaar Head Office Quick Overview

Aadhaar / UIDAI Head Office Address

Aadhaar is administered by the Unique Identification Authority of India (UIDAI). Its national Head Office is:

• UIDAI Head Office: Bangla Sahib Road, Behind Kali Mandir, Gole Market, New Delhi – 110001.
• Office type: National administrative headquarters for Aadhaar policy, coordination, technology, security, enrolment and update functions.
• Not a routine enrolment centre: Normal enrolment and update work is handled through Aadhaar Seva Kendras and authorised centres rather than the national Head Office.

Aadhaar Head Office Phone Number

UIDAI separates its office reception contact from the main public Aadhaar helpline:

• Head Office reception: 011 2347 8653 – the published UIDAI office reception number.
• Aadhaar helpline: 1947 – the main toll-free contact for residents with enrolment, update, status and complaint queries.
• Support email: help@uidai.gov.in – for written Aadhaar assistance.
• Best first contact: For most residents, 1947 is more useful than the Head Office reception because it is designed for Aadhaar service queries.

UIDAI Helpline Timings

UIDAI’s self-service IVRS on 1947 is available 24×7. Contact Centre Executive assistance is available Monday to Saturday from 7:00 AM to 11:00 PM and Sunday from 8:00 AM to 5:00 PM, subject to the national-holiday conditions published by UIDAI. These are helpline hours, not public visitor timings for the New Delhi headquarters.

When to Use an Aadhaar Seva Kendra

Services that require physical verification, biometrics or document submission should be completed at an authorised Aadhaar centre. Depending on the service, residents can book an appointment, locate a centre or use eligible online update options. Carry the original supporting documents required for the specific update. The national head office does not replace the enrolment-centre network.

How to Escalate an Aadhaar Complaint

Keep the relevant EID, URN, SRN or other service reference number. Contact 1947 or use UIDAI’s grievance channels and describe the issue clearly. If the matter concerns a delayed update, provide the request reference and date. For PVC card delivery, keep the order reference. UIDAI can route complaints to the appropriate division or regional office, so complete reference numbers make escalation much faster.

Aadhaar Safety and Privacy

UIDAI repeatedly advises residents to protect Aadhaar-related credentials and use official channels. Do not share OTPs with an unknown caller and do not pay anyone claiming they can ‘unlock’ Aadhaar through an unofficial process. Masked Aadhaar or VID can be useful in situations where sharing the full Aadhaar number is unnecessary. For suspicious authentication activity, use UIDAI’s official services to review and secure the account.

Online Aadhaar Services

Many Aadhaar tasks can now begin online, including downloading e-Aadhaar, checking enrolment or update status, ordering a PVC card, generating a Virtual ID and reviewing authentication-related information. Some updates still require a centre visit because biometric or document verification is necessary. Before travelling, check the current UIDAI service rules and whether an appointment is available. Using online status tools with the correct request number can also prevent an unnecessary visit when an update is still within the normal processing period.

Head Office, Regional Offices and State Offices

UIDAI has a national Head Office as well as regional and state offices that support administration and grievance handling across India. Residents are not expected to choose an office manually for every complaint; the 1947 contact centre and grievance system can route cases internally. This is useful because an Aadhaar issue may relate to enrolment operations, authentication, logistics, technology or another division. A well-documented complaint with the relevant request number is usually more useful than sending the same letter to several UIDAI offices at once.

Appointments and Aadhaar Seva Kendras

For services that require an Aadhaar Seva Kendra visit, check whether online appointment booking is available for the city and service. Bring original documents listed by UIDAI and verify the fee displayed for the service. After the request is submitted, keep the acknowledgement slip and update request number. Residents should not pay agents promising faster approval outside the official process. The head office in New Delhi supervises the system, but the enrolment or update transaction itself should be completed only through an authorised Aadhaar centre or approved online method.

Lost Aadhaar and Digital Copies

A lost printed Aadhaar card does not mean the Aadhaar number is lost permanently. UIDAI provides official ways to retrieve details, download e-Aadhaar and order a PVC card where eligible. Use only UIDAI’s official website, app or 1947 for guidance. Avoid websites or agents that claim they can issue a new Aadhaar number for a fee, because Aadhaar is tied to the individual and routine replacement uses the existing identity record.
