Aadhaar Services - India's National Identity Authority

No Aadhaar number holders can change their VID at any time, so there's no point in storing VID. Databases and logs should never contain VID, as should agencies.

When an Aadhaar holder requests regeneration after their VID has expired for the minimum validity period (currently 1 calendar day), a new VID will be generated and the old VID will be disabled. If a resident requests their VID, the Aadhaar holder will be sent their most recently used VID.

If you're using a verification identifier (VID) system, you'll need the permission of the owner of an Aadhaar Aadhaar number holders must be informed of the authentication's purpose and give their consent before the agency can proceed with the process.

Yes When interacting with the Authentication API, a VID can be used in place of an Aadhaar number. To facilitate authentication, many organizations have committed to updating their Aadhaar authentication application to accept VID by May 31, 2019.

The only person who can create a VID is the owner of an Aadhaar number. UIDAI has established a minimum validity period for VIDs, which is currently 1 calendar day (i.e., they can replace it by generating a new VID after this time has elapsed). e After midnight on the next day, a new VID will be created. Only one VID can be associated with a given Aadhaar number 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. UIDAI will provide these choices through the resident portal, eAadhaar download, Aadhaar Enrolment center, mAadhaar mobile application, etc. 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.

Sending a text message to the Aadhaar support number, 1947, will also 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. The UIDAI resident portal, the eAadhaar website, the Aadhaar Enrollment Centre, the mAadhaar mobile app, and other channels will all offer these choices. At this time, residents can use the UIDAI portal to generate VIDs. A resident's VID number will be sent to their registered mobile number via text message whenever it is needed.

Sending an SMS to the Aadhaar support number 1947 will also retrieve your VID. The resident must use their registered mobile number to send the text "RVIDLast 4 digits of Aadhaar Number" to the number 1947.

In India, you can get the mAadhaar app on your Android or iPhone. Here are the measures to take for the app's setup:

If an individual registers the same Aadhaar number in more than one mobile device, the first number will be deactivated. Only one device at a time can have an Aadhaar number added to it.

The app does not have a save password feature for the security and privacy of Aadhaar cardholders. Because of this, a password is now required whenever a user accesses their profile or My Aadhaar.

A wallet-sized Aadhaar card isn't the only thing an mAadhaar can do. Here are some of the privileges a citizen of India can enjoy if he or she downloads the mAadhaar app:

1. Download Aadhaar, or find a way to get your lost or forgotten Aadhaar number back.
2. It is important for residents to be able to view and show their Aadhaar even when they are not connected to the internet.
3. Aadhaar Address Change with or without Document Verification
4. Manage the Aadhaar numbers for your entire family (up to five people) with just one mobile device.
5. Provide service providers with a paperless eKYC or QR code
6. Locking down Aadhaar with biometrics or Aadhaar is a surefire way to keep sensitive information safe.
7. If a user's Aadhaar has been locked or they simply don't want to share it, they can have a temporary Virtual Identification Number (VID) generated or retrieved to use instead.
8. Take advantage of the offline Aadhaar SMS services.
9. After a resident has submitted a service request, such as enrolling for Aadhaar, ordering a reprint, or updating Adhaar data, the status of that request can be checked in the App through a dashboard called "Request Status Dashboard."
10. Assist those without access to a smartphone to use Aadhaar services through the use of widely available alternatives.
11. Collect past records of updates and authentication attempts
12. Make a Reservation at the Aadhaar Seva Kendra
13. If an update request is processed successfully, residents can use the Aadhaar Sync feature to retrieve their updated Aadhaar profile information.
14. Aadhaar Online Services on the UIDAI Website now support Time-based One-Time Password in place of SMS-based OTP.
15. A user can use the Locate Enrollment Center (EC) tool to identify the enrollment center that is most convenient to their location.
16. The mAadhaar App's More section contains links to the App's Contact, Usage guidelines, Terms & Conditions, and other relevant material.
17. The Aadhaar enrolment or Aadhaar update/correction forms can be downloaded from the More section, along with links to helpful FAQs and the Chatbot.

The mAadhaar app is usable 24/7 throughout India. What you carry in your wallet when you say "Aadhaar card" isn't the same thing as what you carry when you say "mAadhaar." While the mAadhaar profile can be used as an ID at airports and on trains, its real utility lies in the resident's ability to use the app's features to share their eKYC or QR code with service providers who have sought Aadhaar verification of their customers before providing Aadhaar services.  

In order to use the mAadhaar app on an iPhone, the operating system must be iOS 10 or later. Anything greater than zero

No The mAadhaar App can be downloaded and used by any resident of India who owns a smartphone.

Only a subset of Aadhaar-related services (such as Order Aadhaar reprint, Locate Enrolment Center, Verify Aadhaar, Scanning QR code, etc.) will be accessible to residents without a valid Aadhaar-registered mobile number.

All the other Aadhaar services and Aadhaar Profile services available through My Aadhaar require a registered mobile number, though. Anyone with a smartphone can create a profile and register to vote. It's important to note that the OTP will only be sent to the person's registered mobile

The mAadhaar app is only usable by those who already have an Aadhaar number associated with a mobile phone. If they have a smartphone, they can use that device to create a profile and register it. However, the OTP will be sent to only their registered mobile number. Here are the steps you need to follow to create an Aadhaar profile:

1. It's time to start the program
2. Select the Register Aadhaar button located at the top of the main dashboard.
3. Make up a 4-digit password (you'll need to remember this one) to access your profile.
4. Please enter a valid Captcha and provide a valid Aadhaar number.
5. To submit, please enter a valid OTP.
6. The registration of the profile is required.
7. An individual's registered Aadhaar name is now displayed under the tab labeled "registered."
8. To access your Aadhaar information, select the My Aadhaar option from the drop-down menu.
9. Input 4-digit PIN/Password
10. My Aadhaar Profile Shows Up

It's not possible to change personal information in the mAadhaar app. Presently, the only accessible method for changing your address is through a document facility.  

Future updates may include the demographics-related features, though.

No The mAadhaar App is available for free to any resident of India who owns a smartphone.

Residents will have limited access to Aadhaar services (such as finding an enrollment center, verifying an existing Aadhaar, scanning a QR code, etc.) if they do not have a mobile phone number linked to their Aadhaar.

All the other Aadhaar services and Aadhaar Profile services available through My Aadhaar require a registered mobile number, though. Profiles can be created by residents using an app downloaded to any smartphone. However, only their registered mobile number will receive the OTP.

The mAadhaar app is available for both iOS and Android devices, and it offers the same set of features to both platforms. All devices (iOS, Android) have the same features and user experience.

The profile summary (picture, name, and Aadhaar number on a cyan tab) is accessible from the main dashboard via a tap. Aadhaar profile access procedure:

1. Get the app going.
2. The Aadhaar Profile tab can be accessed from the main dashboard's upper right corner.
3. To continue, please enter your 4-digit PIN/password that you selected when you set up your profile.
4. There is an Aadhaar card, and it shows the front. The reverse can be seen by sliding to the left.
5. To see the additional profiles, keep swiping to the left.

Important: To view your Aadhaar profile and use the associated services, tap the My Aadhaar tab located at the bottom of the Dashboard screen.

To complete Aadhaar Authentication, Aadhaar number holders can access the following UIDAI services:

• The Aadhaar number verification service will allow both service providers and Aadhaar number holders to confirm that the provided number is active and valid.
• Service providers and Aadhaar number holders can use this feature to confirm the Aadhaar number is active and valid.
• Biometric Locking/Unlocking: Individuals with an Aadhaar number can use this feature to safeguard their biometric authentication. If the same is locked, nobody can use it to verify their identity. Before conducting any transaction requiring biometric authentication, locals have the option to unlock their biometrics.
• Aadhaar cardholders can verify the linking status of their Aadhaar and bank account. The NPCI Server is queried for the current status of Aadhaar linking. UIDAI disclaims all responsibility and liability for the accuracy of the status information provided at any time. UIDAI also does not save any data that it obtains from the NPCI server. 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.
• If you have an Aadhaar number, you can use it to make a 16-digit Virtual ID (VID).

When a resident of India logs into the UIDAI website, they can access a service called "Aadhaar Authentication history," which details all of the authentication attempts that have been made on their behalf in the

UIDAI offers multiple methods of authentication, including demographic, biometric (fingerprint or iris), and One-Time-Password (OTP) verification. A transaction's Auth Modality indicates the method of authentication that was used to complete that transaction.

A unique error code is assigned to each record of an authentication transaction that was unsuccessful. In order to determine the cause of the failed authentication transaction, please refer to the specific error code number.

If a resident is unable to complete any of the aforementioned authentication transactions using their Aadhaar number, they should get in touch with the appropriate Authentication User Agency (AUA).

UIDAI Websites allow residents to look up their own Aadhaar Authentication records by entering their Aadhaar Number/VID and then following the on-screen instructions.

You must have a valid, registered phone number in order to use this service.

UIDAI creates a unique code for each authentication transaction performed by an Aadhaar number holder, and sends it to the Authentication User Agency (AUA) along with the response. The Aadhaar holder can use this Response Code for any follow-up questions with AUA and it will help AUA and UIDAI identify the transaction.

In the Aadhaar Authentication history, residents can view the following details about each authentication they've performed:

Authority Modality, No. 1 2 Time and Date of Verification 3 Code returned from UIDAI 4 AUA Name5 Acquirer Reference Number (Including Code) for the AUA6 Successful Authentication or Failed Authentication7 Error code from 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. A maximum of 50 records can be viewed at any given time.

The Aadhaar Authentication Service Provider (AUA) creates a unique Transaction ID for each authentication transaction and sends it along with the authentication request it sends to the Unique Identification Authority of India (UIDAI). The holder of the Aadhaar number can use the Transaction ID and Response Code for any future inquiries with AUA.

Hashing is most commonly 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. By comparing the hash values of the source and destination files, the user can check that the transferred file is in good condition. If they match, the transferred file is an exact replica of the original.

A virtual drive container file is an example of an encrypted file that may be created with the intention of never changing the file size or the last modification date and time. It would be impossible to tell at a glance if two similar files were different, but the hash values would easily tell the difference.

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 final four digits of the Aadhaar number 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. Your application is available for download at uidai. gov in The use of a high-quality, STQC-approved QR Code scanner is also required.

To ensure the security of your e-Aadhaar's QR code, it is strongly advised that you only use a LaserJet printer when printing.

After the UIDAI QR code reader app has been installed, the secure QR code of the e-Aadhaar must be scanned using the physical scanner in accordance with UIDAI Specifications. Once the e-Aadhaar QR code has been digitally verified by UIDAI at the backend, the application will show the resident's demographic information. If the digital signature cannot be verified, the reader will show a "QR Code not verified" GUI Screen.

If you need to verify your e-Aadhaar information without an internet connection, you can use this service. This includes both Aadhaar cardholders and service providers like banks, AUAs, KUAs, and others.

Please take note that on February 20, 2018, a new QR Code was implemented for use with e-Aadhaar, and that a client for reading these codes can be found on uidai. gov commencing 27 March 2018

The Aadhaar secure QR code can be found in the UIDAI e-Aadhaar letter. UIDAI has changed the QR code on e-Aadhaar so that it only contains the last four digits of the holder's Aadhaar number, along with 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. Further, a UIDAI digital signature will be affixed to this data to make it even more secure and impossible to alter. UIDAI's Windows-based Custom client for PCs and Macs is required to read and verify the authenticity of the QR code's digital signature. Thus, any attempt at e-Aadhaar fraud can be easily uncovered with the aid of a QR code scanner.

Hashing is an algorithm that takes a file and returns a value encoded as a string of bits. Blocks of information are what make up a file. Through a process called hashing, the original string is converted into a much shorter fixed-length value or key. One could think of the hash value as a shorthand for the contents of the file.

The avalanche effect is a characteristic of a good hashing algorithm in which the hash output shifts significantly or completely when only 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.

As a rule, a hash is a series of hexadecimal digits. In addition, hashing is a one-way process; the original data can never be recovered by using it.

Hashes are typically a series of hexadecimal digits. Additionally, hashing is a one-way process; the original data can never be recovered by using it.

By checking the HASH, we can be sure that the client installed is the official UIDAI release. For the purpose of authentication, UIDAI will provide SHA-1 and SHA-256 hashing algorithms.

It is a safe, transferable document that anyone with an Aadhaar number can use to verify their identity in person.

A resident who wishes to make use of this service must first visit the UIDAI resident portal in order to create digitally signed Aadhaar details. Name, Address, Photo, Gender, Date of Birth, Registered Mobile Number hash, Registered Email Address hash, and Reference ID consisting of the last 4 digits of the Aadhaar Number followed by a time stamp will all be included in the digitally signed XML file containing the details. 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:

Providing the service provider with a valid form of identification such as a PAN card, passport, etc. is usually sufficient for identity verification. Even though they could be used as proof of identity, any of the aforementioned items are susceptible to forgery and could take time to verify offline if at all. The verifier of documents must rely on the producer's word alone because no technological means exist to confirm the document's or information's veracity. Aadhaar Paperless Offline e-KYC, on the other hand, generates an XML file that is digitally signed by the UIDAI. This allows the service provider to ensure the authenticity of the file and its demographic information during the offline verification process.

Providers are prohibited from disclosing, publishing, or displaying the contents of the Share Code or associated XML file to any third party. There will be legal repercussions for failing to follow these procedures, per 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.

Residents and service providers can arrange a time that is convenient for both parties to exchange the XML ZIP file and Share Code.

Below is a breakdown of how Aadhaar Offline e-KYC is created:

• Follow this link https://resident.uidai.gov.in/offlineaadhaar to get your Aadhaar card without an internet connection:
• Click the "Send OTP" or "Enter TOTP" button after entering your "Aadhaar Number" or "VID" and the "Security Code" that the screen prompts you to enter. If you enter an Aadhaar or VID, an OTP will be sent to the mobile phone associated with that number. The UIDAI mobile application, m-Aadhaar, will soon feature TOTP. Type in the one-time password/one-time OTP that you were given. First, you'll need to enter a Share Code, which will serve as the ZIP file's password.
• After following the aforementioned procedures, the Zip file containing the digitally signed XML will be downloaded to the device.

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. This Aadhaar paperless offline e-KYC must be provided by the service provider at their location, where offline verification must also take place.
