It is a secure sharable document which can be used by any Aadhaar number holder for offline verification of Identification.
A resident desirous of using this facility shall generate his/her digitally signed Offline XML by accessing UIDAI website. The Offline XML will contain Name, Address, Photo, Gender, DOB, hash of registered Mobile Number, hash of registered Email Address and reference id which contains last 4 digits of Aadhaar Number followed by time stamp. It will provide Offline Aadhaar Verification facility to service providers/Offline Verification Seeking Entity (OVSE) without the need to collect or store Aadhaar number.
How to generate Offline Aadhaar XML? Open or Close
The process of generating Aadhaar Offline e-KYC is explained below:
• Go to URL https://myaadhaar.uidai.gov.in/offline-ekyc
• Enter ‘Aadhaar Number’ or ‘VID’ and enter mentioned ‘Security Code’ in screen, then click on ‘Send OTP’. The OTP will be sent to the registered Mobile Number for the given Aadhaar number or VID. OTP will be available on m-Aadhaar mobile Application of UIDAI. Enter the OTP received. Enter a Share Code which be the password for the ZIP file and click on ‘Download’ button
• The Zip file containing the digitally signed XML will be downloaded to device wherein the above mentioned steps have been performed.
The Offline Aadhaar XML can also be downloaded from mAadhaar app.
Who are the users of this Aadhaar Paperless Offline e-KYC? Open or Close
Any Aadhaar number holder who desires to establish his/her identity to any service provider (OVSE) using digitally signed XML downloaded from UIDAI website can be a user of this service.

How to share this Paperless Offline eKYC document with the service provider? Open or Close
Residents can share the XML ZIP file along with the Share Code to the service provider as per their mutual convenience.
How will service providers use Aadhaar Offline e-KYC? Open or Close
The process of Aadhaar Offline e-KYC Verification by Service Provider is:
- Once service provider obtains the ZIP file, it extracts the XML file using the password (share code) provided by the resident.
- The XML file will contain the demographic details such as Name, DOB, Gender and Address. Photo is in base 64 encoded format which can be rendered directly using any utility or plane HTML page. Email Address and Mobile number are hashed.
- Service Provider has to collect Email Address and Mobile number from residents and perform below operations in order to validate the hash:
Mobile Number:
Hashing logic: Sha256(Sha256(Mobile+ShareCode))*number of times of last digit of Aadhaar Number
Example :
Mobile number: 9800000002
Aadhaar Number: 123412341234
Share Code: Abc@123
Sha256(Sha256(9800000002+ Abc@123))*4
In case if Aadhaar Number ends with Zero or 1 (123412341230/1) it will be hashed one time.
Sha256(Sha256(9800000002+ Abc@123))*1Email Address:
Hashing Logic: This is a simple SHA256 hash of the email without any salt
- Entire XML is digitally signed and Service Provider can validate the XML file using the signature and public key available on the UIDAI website.(https://uidai.gov.in/images/uidai_offline_publickey_26022019.cer).
Can this Offline Paperless eKYC document be shared to other entities by the Service Provider? Open or Close

How this Aadhaar Offline Paperless eKYC document is different from the other identification documents produced offline by residents? Open or Close
Identity verification can simply be accomplished by providing an identity document like PAN card, Passport etc to the service provider. However, all these documents, which may be used for identification can still be forged and faked which may or may not be possible to verify offline instantaneously. The document verifier has no technological means to verify the authenticity of the document or the information it contains and has to trust the document producer. Whereas, the XML file generated by the Aadhaar number holder using Aadhaar Paperless Offline e-KYC is digitally signed document using UIDAI digital signature. Thus, the service provider can verify the demographic contents of the file and certify it to be authentic when doing the offline verification
