For an actual person, the contact-centre executives are there Monday to Saturday, 7 a.m. to 11 p.m., and Sunday, 8 a.m. to 5 p.m. You can take the call in any of twelve languages.

UIDAI Email and Chat Support
When you would rather have it in writing, email help@uidai.gov.in. It suits anything detailed or where you want a paper trail or need to attach a document, and it does not need a registered mobile. For quick answers, UIDAI runs an AI chatbot, Aadhaar Mitra, on its website it fields common questions and can pull up some statuses, like a PVC card or an enrollment update. The one thing to remember: the chatbot is for queries, not for lodging a formal complaint. For that, fall back on the helpline, email, the grievance portal, or CPGRAMS.
Postal Address and Regional UIDAI Offices
If you need to write to UIDAI by post, the Head Office is in Delhi:
Unique Identification Authority of India (Government of India), Bangla Sahib Road, Behind Kali Mandir, Gole Market, New Delhi – 110001.
UIDAI also keeps Regional Offices around the country Delhi, Mumbai, Hyderabad, Bengaluru, Chandigarh, Lucknow, Ranchi, Guwahati and more each covering a cluster of states. Since a complaint lands best at the office that handles your state, look up the current address for your region on UIDAI’s Regional Offices page rather than trusting one fixed address. A letter posted or handed in to the right Regional Office leaves a written record, which is exactly what you want for anything the faster channels could not sort out.
How to Complain About an Aadhaar Centre
If an enrolment centre overcharges you, turns you away, or behaves badly, you can report it and it is worth doing. Jot down the centre’s name or code and the date, then raise it on 1947, through “File a Complaint” on uidai.gov.in, or by email, quoting your EID if you have one. Overcharging is one of the most common and most valid complaints, because UIDAI fixes the fee for each service and anything above that is simply not allowed. A specific, dated report naming the centre gets acted on far more readily than a vague grumble, so use the details you noted down.
UIDAI Grievance Redressal Process
Behind all these contact points sits a proper grievance system. The short version: you raise a complaint through any channel, it is handed to the relevant division or Regional Office, looked into, and the outcome comes back to you usually aimed at within about 30 days. If it stalls, you escalate, mainly through the Government’s CPGRAMS portal at pgportal.gov.in, and, once past UIDAI’s 90-day service window, by an RTI request. The full step-by-step timelines, escalation ladder, the lot lives in our dedicated guide to filing a UIDAI complaint and checking its status, which this page links to.

Frequently Asked Questions (FAQs)
What is UIDAI helpline number?
The UIDAI helpline is 1947, a toll-free number also reachable as 1800-300-1947. Call it for any Aadhaar query or to register a complaint, in any of twelve languages. Simple questions are answered directly, while complaints are logged and routed to the relevant UIDAI division. It is free from both mobile and landline phones.
Is UIDAI helpline 24x7?
Partly. The automated IVRS on 1947 runs 24×7, so self-service options like status checks work at any hour. To speak with a live executive, the hours are Monday to Saturday, 7 a.m. to 11 p.m., and Sunday, 8 a.m. to 5 p.m. So it is round-the-clock for automated help, daytime and evening for a human.
How to contact UIDAI via email?
Email help@uidai.gov.in with your query or complaint. This is the route to choose when you want a written record or need to attach a document, and it does not require a registered mobile number. Add your EID, URN, or SRN where relevant so UIDAI can find your case quickly. Expect a reply within a few working days.
How to chat with UIDAI support?
Use Aadhaar Mitra, UIDAI’s AI chatbot on uidai.gov.in. It answers common Aadhaar questions in real time and can show some statuses, such as a PVC card or enrolment update. It is great for a quick query, but it cannot register a formal complaint for that, use the 1947 helpline, email, the grievance portal, or CPGRAMS.
Where is UIDAI head office?
The UIDAI Head Office is in New Delhi, at Bangla Sahib Road, Behind Kali Mandir, Gole Market, New Delhi – 110001. UIDAI also runs Regional Offices in cities across India, each serving a group of states. For most issues, the Regional Office that covers your state is more useful to contact than the Head Office directly.
How to complain about Aadhaar centre?
Note the centre’s name or code and the date, then report it via 1947, the File a Complaint page on uidai.gov.in, or email, quoting your EID if you have it. Overcharging is a valid complaint, since UIDAI sets fixed fees and anything above them is not allowed. A specific, dated report naming the centre is acted on far more readily than a vague one.
What is UIDAI grievance redressal process?
You lodge a complaint through any channel, UIDAI assigns it to the relevant division or Regional Office, examines it, and tells you the outcome usually aimed at within about 30 days. Unresolved cases get escalated, mainly through CPGRAMS and, beyond the 90-day service window, by an RTI request. Keeping your EID, URN, or SRN handy speeds the whole thing up.
How to escalate UIDAI complaint?
If your complaint stalls, lodge it on the Government’s CPGRAMS portal at pgportal.gov.in, which is centrally monitored and tends to get a firmer response than repeat calls. Past UIDAI’s 90-day Citizen Charter window, you can file an RTI to its Central Public Information Officer for the status and reason for delay, answerable within 30 days. A Regional Office application is a further on-record step.
