Offline Aadhaar XML is a secure, shareable document format introduced by UIDAI to facilitate Paperless Local KYC. It is a digitally signed XML file that contains your demographic details (Name, Address, Photo, Gender, DOB, Hash of Mobile/Email) but does not contain your full Aadhaar number.
Unlike online e-KYC which requires biometric device or OTP connectivity with UIDAI servers, the Offline XML file can be verified by any agency locally on their computer without hitting the UIDAI server. This makes it a privacy-preserving and robust method for KYC verification.
What Does Offline Aadhaar XML Mean?
It stands for “Aadhaar Paperless Offline e-KYC”.
- File Format: A ZIP file containing an XML document.
- Security: The XML is digitally signed by UIDAI, ensuring it hasn’t been tampered with.
- Data Hiding: It uses a “Reference ID” instead of the Aadhaar number.
- Verification: The agency can validate the data by checking the digital signature.
Why Offline Aadhaar XML is Important
- Privacy: You don’t have to share your Aadhaar number.
- Security: Since it’s offline, there is no risk of biometric data theft or server hacking during the process.
- Accessibility: It works even in areas with poor internet connectivity, as the verification is local.
Where is Offline Aadhaar XML Used?
- Job Verification: Employers use it to verify staff identity.
- Tenant Verification: Landlords can use it to verify tenants.
- Financial Services: Non-banking entities often use this for KYC compliance where full biometric e-KYC is not permitted.
How to Find or Download Offline Aadhaar XML
- Login: Go to the myAadhaar portal.
- Select: “Offline e-KYC”.
- Create Share Code: You must create a 4-digit “Share Code” (e.g., 1234). This code acts as the password to unzip the file.
- Download: The ZIP file is downloaded to your device.
- Share: Give the ZIP file and the 4-digit code to the verifying agency.
Example of XML Usage
Scenario: You are joining a new company.
- Action: Instead of giving a photocopy of Aadhaar, you download the XML file with Share Code ‘9988’.
- Submission: You email the ZIP file to HR.
- Verification: HR uses the Share Code to open the file, sees your photo and address signed by UIDAI, and confirms your identity.
Common Problems or Errors
- Wrong Share Code: If you forget the 4-digit code you set, the agency cannot open the file. You have to download a fresh one.
- Mobile Not Linked: You cannot download this file if your mobile number is not registered with Aadhaar, as OTP is needed for login.
Important Things to Remember
- The file is valid as long as your details haven’t changed.
- It is the most secure way to share data with private entities.
- For simple visual ID, Masked Aadhaar is better; for data processing, XML is better.
Frequently Asked Questions
What is the Share Code in Offline Aadhaar?
The Share Code is a temporary 4-digit password that you create yourself when downloading the Offline XML file. You must share this code with the agency so they can unzip and access your data.
Is Offline Aadhaar XML accepted by banks?
Yes, RBI has included Offline Verification via Aadhaar XML as a valid mode of KYC (Know Your Customer) for banks and NBFCs.
Does the XML file contain my mobile number?
No, for privacy, it does not contain the mobile number in plain text. It contains a “Hash” of the mobile number. The agency can hash your provided number and match it with the XML to verify it’s the same.
How do I open the Offline Aadhaar XML ZIP file?
You need a ZIP extractor software. When prompted for a password, enter the 4-digit Share Code you created during the download.
