Unique Enrollment Number and Aadhaar Service Center of India
No Aadhaar number holders can change their VID at any time, so there's no point in storing VID. Organizations shouldn't keep VID in any logs or databases.
The holder of an Aadhaar number can only have a VID generated by an AUA or KUA.
A new VID will be generated and the old one will be deactivated after the minimum validity period (currently set as 1 calendar day) has elapsed, provided the holder of the Aadhaar number requests regeneration. The last valid VID will be sent to the person who owns the Aadhaar number if the resident chooses to retrieve their VID.
For VID-based authentication, yes, Aadhaar holder permission is required. To authenticate an Aadhaar number, the agency must first obtain the cardholder's informed consent after explaining the authentication's intended use.
The VID is a 16-digit number generated at random and associated with the permanent Aadhaar number. When performing authentication or electronic Know Your Customer (e-KYC) services, a VID can be used instead of an Aadhaar number. VID can be used for authentication in the same way that an Aadhaar number is. The Aadhaar number cannot be determined from the VID.
Yes Instead of an Aadhaar number, a VID can be used in the Authentication API. By May 31, 2019, different organizations will have updated their Aadhaar authentication app to accept VID as an input for authentication.
The only person who can make a VID is the one who has an Aadhaar number. UIDAI has established a minimum validity period for VIDs, which is currently 1 calendar day, after which they can be replaced (a new VID generated) at any time. e After midnight on the next day, a new VID will be created. An Aadhaar number can only have one VID active at any given time. UIDAI will give those with an Aadhaar number multiple ways to create a VID, retrieve a forgotten VID, or get a new VID issued. The UIDAI resident portal, the eAadhaar app, the Aadhaar enrolment center, and the mAadhaar mobile app are all channels through which these choices will be made available. UIDAI's resident portal currently supports VID generation. Residents will have their VID sent to their registered mobile number via SMS whenever it is needed.
SMS messages sent to the Aadhaar support number 1947 can also be used to generate a VID. Sending "GVIDLast 4 digits of Aadhaar Number" via the resident's registered mobile number to 1947 is required.
UIDAI will, indeed, offer a variety of options for creating and retrieving VIDs. UIDAI will provide access to these features via the resident portal, eAadhaar, Aadhaar Enrollment centers, the mAadhaar mobile app, and other channels. UIDAI's resident portal now has the ability to create a VID. Residents will receive an SMS on their registered mobile number with their VID number whenever it is needed.
Sending an SMS to the Aadhaar helpline number 1947 will also return your VID. To verify their identity, residents can text "RVIDLast 4 digits of Aadhaar Number" to 1947 from their registered mobile phone number.
The mAadhaar app can be downloaded by Indians on both Android and iOS devices. Here are the measures to take for the app's installation:
If an individual registers the same Aadhaar number in more than one mobile device, the first number will be deactivated. One Aadhaar enrollment per device is permitted.
The app does not have a save password feature for the security and privacy of Aadhaar cardholders. Therefore, every time a user wants to access their profile or My Aadhaar, they will need to enter a password.
mAadhaar is more than just a replacement for the Aadhaar card The local can receive the following advantages by downloading the mAadhaar app:
- Download Aadhaar, or find a way to get your lost or forgotten Aadhaar number back.
- It is important for residents to be able to view and show their Aadhaar card even when they are not connected to the internet.
- Change Your Known Address in Aadhaar With or Without Proof
- You can store and manage the Aadhaar information for your entire family (up to five people) using just one mobile device.
- Provide service providers with a paperless eKYC or QR code.
- Locking in Aadhaar or biometrics is a great way to keep it safe.
- Users who have locked their Aadhaar or do not wish to share their Aadhaar can instead use a VID that has been generated for them or that they have retrieved from the Aadhaar database.
- Obtain Aadhaar SMS support even when you're not online.
- Residents can check the status of their service request made after enrolling in Aadhaar, ordering a reprint, or updating their Adhaar data through the App's "Check Request Status Dashboard."
- Share your common services with those who don't have smartphones so they can use Aadhaar.
- Obtain a log of all authentication attempts and updates.
- Schedule a visit to the Aadhaar Seva Kendra.
- After a successful update request has been processed, residents can access their updated Aadhaar profile information using the Sync feature.
- Aadhaar Online Services on the UIDAI Website now support Time-based One-Time Password in place of SMS-based OTP.
- Find your local enrollment center with the help of Locate Enrollment Center (EC).
- The mAadhaar App's More section contains links to the App's Contact, Usage guidelines, Terms & Conditions, and other relevant information.
- The Aadhaar enrolment or Aadhaar update/correction forms can be downloaded from the More section, along with links to helpful FAQs and the Chatbot.
In India, the mAadhaar app can be used at any time and in any location. mAadhaar is more than just a replacement for the Aadhaar card. The mAadhaar profile can be used as identification at airports and on trains, and its users can also use the app's features to provide their eKYC or QR code to businesses that require Aadhaar verification before they provide their services.

For Aadhaar Authentication, the following UIDAI services are utilized by Aadhaar number holders:
- Service providers and Aadhaar number holders will be able to confirm the Aadhaar number is active and active by using this feature.
- Service providers and Aadhaar number holders can use this feature to confirm the Aadhaar number is active and valid.
- Users with an Aadhaar number can lock their biometric authentication for added security. Once the same is locked, it can no longer be used for authentication. Before engaging in any biometric authentication transaction, locals have the option to unlock their biometrics.
- To see if your Aadhaar number has been linked to your bank account, visit the UIDAI website. The NPCI Server is queried for the current status of Aadhaar linking. Under any circumstance, UIDAI shall not be responsible or liable for the correctness of the displayed status The data retrieved from the NPCI server is not stored by UIDAI. The Supreme Court ruled on December 26 that linking a bank account with an Aadhaar number is not obligatory. 9 2018
- Users with an Aadhaar number can check their Aadhaar Authentication history to see every time they've authenticated their number.
- To create a 16-digit Virtual ID (VID), Aadhaar number holders can use a virtual ID generator.
Aadhaar Authentication history service hosted on UIDAI Website provides details of authentication performed by the individual resident in past
The demographic, biometric (fingerprint or iris), and One-Time-Password (OTP) authentication methods are all available through UIDAI. The Auth Modality field reveals the method of authentication that was employed for this particular authentication procedure.
Each instance of a failed authentication transaction is recorded with its own unique error code. In order to determine the cause of the authentication failure, please review the information associated with the specific error code number.
If a resident is unable to complete an authorized authentication transaction using their Aadhaar number, they should get in touch with the appropriate Authentication User Agency (AUA).
Following the on-screen prompts and entering one's Aadhaar Number/VID, residents can view their authentication records through UIDAI websites.
Please be aware that in order to use this service, a valid phone number must be on file.
UIDAI creates a unique code for each authentication transaction performed by an Aadhaar number holder and sends it to the Authentication User Agency (AUA) together with the response. This Response Code is useful for uniquely identifying the transaction by AUA and UIDAI, and the Aadhaar number holder may use it for any follow-up enquiry with AUA.
Against each authentication the resident has performed using Aadhaar, the resident can access the following details.
Authoritative Modality 2 Authentication Date and Time 3 Code returned from UIDAI 4 AUA Name5 AUA Order Number (Including Code)6 Success/Failure of Authentication7 Code d'erreur UIDAI
Every authentication record made in the last six months, whether by an AUA or the holder of the Aadhaar number, can be viewed by the holder of the Aadhaar number. However, only 50 records at a time can be viewed.
AUA creates a unique Transaction ID for each authentication transaction performed by an Aadhaar number holder, and sends it along with the authentication request to UIDAI. The owner of the Aadhaar number can contact AUA with any further questions using the provided Transaction ID and Response Code.
Password is the first four letters of your name, all capitalized, plus your birth year, in YYYY format.
Case in point:
First Example: SURESH KUMARY's Birth Year is 1990, So the Password Is "SURE1990"
Example 2SAI KUMARY Birth Date 1990 Password SAIK1990
Example 3Name: P Birthday: 1990Gender: FPassword: KUMARY KU1990
Example 4RIA's birthday is 1990, so the password is RIA1990.
Hashing is most often used to check two files for equality. The owner will be able to tell at a glance whether or not two files are different based on their hash values, even without opening them and comparing every single word.
In file backup programs like SyncBack, hashing is used to ensure that no data has been corrupted during the transfer process. A user can check the integrity of the transferred file by comparing their hash values. If they're identical, the transferred file is an exact replica of the original.
For security reasons, some encrypted files (such as virtual drive container files) are created with a hardcoded size and last modification time. It would be impossible to tell at a glance whether or not two seemingly identical files are actually distinct, but their hash values would reveal any discrepancies.
Both e-Aadhaar QR codes include the resident's name, address, date of birth, gender, and a hashed version of their Aadhaar number (known as a "masked" number). e Aadhaar's final four digits The larger QR code also includes a photo.
Only UIDAI's Windows-based app can decode the newly digitally signed QR code and check it against UIDAI's own database of digital signatures. You can get the application from uidai. gov in In addition, a high-quality QR Code scanner that is STQC-approved will be needed.
The use of a LaserJet printer is strongly suggested for printing e-Aadhaar cards that contain the encrypted QR code.
The secure e-Aadhaar QR code must be scanned using the physical scanner after the UIDAI QR code reader application has been installed, per UIDAI Specifications. Once the e-Aadhaar QR code has been digitally verified by UIDAI at the backend, the application will display the resident's demographic information. In the event that the QR code's digital signature cannot be validated, the reader will show the user an appropriate error message.
This feature can be used by anyone to verify their e-Aadhaar information offline, including Aadhaar cardholders and service providers like banks, AUAs, KUAs, and more.
Please take note that on February 20, 2018, a new QR Code was implemented for use with e-Aadhaar, and a client for scanning these codes can be found at uidai. gov starting March 27th, 2018
The Aadhaar secure QR code is included in the UIDAI e-Aadhaar letter. UIDAI has changed the QR code on e-Aadhaar from the old, unprotected version to a new, encrypted one that includes the last four digits of the holder's Aadhaar number as well as their name, address, gender, date of birth, and photograph. A small QR Code containing only demographic information will be located on the front of the cutaway portion, and a larger QR Code containing both demographic information and a photo will be located on the top portion of the front and rear of the cutaway portion. In addition, a digital signature from UIDAI will be used to make this data even more secure and impossible to alter. Only UIDAI's Windows-based Custom client for PCs and Macs can read the new digitally signed QR code and instantly verify it against UIDAI digital signatures. Since QR Code scanners are so widely available, any attempt at e-Aadhaar fraud will be quickly uncovered.
Hashing is an algorithm that takes a file and returns a value encoded as a string of bits. Data is organized into blocks within a file. The information is hashed, which reduces the length of the original string to a fixed-length value called a key. The hash value represents a condensed version of the contents of the file.
The avalanche effect is a characteristic of a good hashing algorithm in which the hash output shifts drastically or completely when even a single bit or byte of data within a file is modified. Any hash function that doesn't do this is thought to have insufficient randomization and is therefore vulnerable to attack.
A hash is typically a long string of hexadecimal digits. Furthermore, hashing is a one-way process; the original data can never be recovered by using it.
A hash is typically a long string of hexadecimal digits. Since hashing is a one-way process, it is impossible to recover the original information.
By checking the HASH, we can be sure that the client installed is the official UIDAI release. For authentication purposes, UIDAI will supply SHA-1 and SHA-256.
It's a safe, transferable document that anyone with an Aadhaar number can use to confirm their identity in person.
If a local wants to sign their Aadhaar information digitally, they can do so through the UIDAI resident portal. The information will be presented in a digitally signed XML file, and it will include the person's name, address, photo, gender, date of birth, hash of registered mobile number, hash of registered email address, and reference id, which is the last four digits of their Aadhaar number, followed by a time stamp. Without requiring them to collect or store Aadhaar numbers, it will allow service providers/Offline Verification Seeking Entity (OVSE) to use the Offline Aadhaar Verification facility.
Offline e-KYC Verification with Aadhaar by Service Provider Process:
- The service provider receives the ZIP file from the resident, and then extracts the XML file using the resident's provided password (share code).
- Name, Date of Birth, Gender, and Address information will all be included in the XML file. All you need is an HTML page or an app to view the base 64 encoded photo. Your phone number and email address have been hashed.
- The following steps must be taken by the Service Provider in order to validate the hash: Collect resident's email addresses and mobile phone numbers
Cellular Phone Number:
Aadhaar hashing algorithm = Sha256(Sha256(Mobile ShareCode)) * Aadhaar checksum
Text me at 9800000002 on your cell!
Number of Aadhaar: 123412341234
Symbol for Stock: ABC@123
For example: Sha256(Sha256(9800000002) Abc@123))*4
The Aadhaar number will be hashed once if the last digit is a zero or a one (123412341230/1).
This is a plain SHA256 hash of the email, with no salt added.
- The entire XML is digitally signed, and the Service Provider can use the signature and public key from the UIDAI website to verify the integrity of the XML. (https://uidai.gov.in/images/uidai_offline_publickey_26022019.cer)
The service provider only needs the customer to present an identity document (PAN card, passport, etc.) in order to verify the customer's identity. It may or may not be possible to instantly verify offline whether or not any of the documents that could be used for identification are genuine. Without access to appropriate technological resources, the verifier of a document must rely on the producer's word that the document and its contents are genuine. Aadhaar Paperless Offline e-KYC, on the other hand, generates an XML file that is digitally signed by the UIDAI. As a result, the service provider can confirm the accuracy of the file's demographic information during the offline verification process.
Neither the Share Code nor the XML file, nor any information contained therein, may be distributed, published, or displayed by Service Providers. Actions under Sections 17 and 25 of The Aadhaar (Authentication) Regulation, 2016, Sections 4 and 6 of The Aadhaar (Sharing of Information) Regulation, 2016, and Sections 29(2), 29(3), and 37 of The Aadhaar Act, 2016 will be taken against anyone who does not comply with these requirements.
The Share Code and XML ZIP file can be easily shared between residents and service providers.
Below is a breakdown of how Aadhaar Offline e-KYC is created:
- The address to visit is https://resident.uidai.gov.in/offlineaadhaar.
- Simply type in your "Aadhaar Number" or "VID" and the "Security Code" that is displayed on the screen, and then select either "Send OTP" or "Enter TOTP." If you enter an Aadhaar or VID, an OTP will be sent to the mobile phone associated with that number. UIDAI's m-Aadhaar mobile application is where you can find TOTP. Fill in the received OTP/TOTP. To access the ZIP file, enter the Share Code that was provided to you and then click the "Download" button.
- After following the above steps, the device will download a Zip file containing the digitally signed XML.
Users of this service are Aadhaar cardholders who wish to verify their identity with an OVSE by submitting digitally signed XML obtained from the UIDAI website. Service providers need to be able to provide Aadhaar paperless offline e-KYC at their location and conduct offline verification.
