If you're reading this, chances are you're staring at an enrolment slip, wondering when your official Aadhaar card will finally be ready. Or perhaps you've misplaced your 12-digit Unique Identification Number (UID) and need to retrieve it urgently. We get it—navigating complex government portals and understanding bureaucratic acronyms can feel like deciphering an ancient language.
Whether you've just applied for a brand-new Aadhaar, requested a demographic update, or need to verify a card's authenticity for professional reasons, performing an Aadhaar card check online by number doesn't have to be a headache. In this comprehensive, highly actionable guide, we will walk you through exactly how to track, retrieve, and verify your Aadhaar details from the comfort of your home—and how to fix the pesky signature errors once you finally download your card.
Understanding the Jargon: EID, URN, and UID Explained
Before we dive into the specific steps to check your status, let's clear up the alphabet soup that the Unique Identification Authority of India (UIDAI) uses on their portal:
- UID (Unique Identification Number): This is your actual, permanent 12-digit Aadhaar number.
- EID (Enrolment ID): A 28-digit number (a 14-digit enrolment number followed by a 14-digit date and time stamp) printed at the top of the acknowledgement slip you received at the Aadhaar Seva Kendra.
- URN (Update Request Number): A 14-digit number generated specifically when you request an update to your demographic or biometric details (like changing your address online).
Method 1: How to Check Aadhaar Card Status Using Your Enrolment Number (EID) or URN
If you are waiting for a new card or an address update to process, you cannot check the status with just a phone number; you need your EID or URN. Here is exactly how to do it in five easy steps:
- Visit the Official UIDAI Portal: Head over to the official website at myaadhaar.uidai.gov.in and scroll down to the "Check Enrolment & Update Status" section.
- Locate Your Slip: Pull out the physical acknowledgement slip you received when you applied or updated your details.
- Enter Your Details: Input your 28-digit EID or 14-digit URN carefully into the provided text box. Make sure you don't add any spaces, hyphens, or special characters.
- Solve the Captcha: Type the alphanumeric security code displayed on the screen. (If the characters are too blurry to read, simply hit the refresh icon next to it for a new code).
- Hit Submit: Click the 'Submit' button. The portal will instantly display the stage of your application—whether your Aadhaar is in the draft stage, under process, or successfully generated!
Method 2: Aadhaar Card Check Online by Mobile Number (For Lost or Forgotten UID)
Panic inevitably sets in when you realize your physical Aadhaar card is nowhere to be found, and you haven't memorized the 12-digit number. Take a deep breath. As long as your current mobile number or email address is actively linked to your Aadhaar profile, retrieving your number is a breeze.
Steps to Retrieve a Lost Aadhaar Number:
- Go to the main myAadhaar portal and click on the "Retrieve EID/Aadhaar number" tile.
- Select whether you want to retrieve your Aadhaar Number (UID) or your Enrolment ID (EID). (Choose UID if you want the actual card number).
- Enter your full legal name exactly as it was registered on your card.
- Enter your registered mobile number or your registered email address.
- Fill in the Captcha code and click on "Send OTP".
- Check your phone for a 6-digit One-Time Password. Enter it into the portal and hit verify.
Success! Your 12-digit Aadhaar number will be sent directly to your registered mobile number via SMS. You can now use this number to log in and download a digital copy (e-Aadhaar) to your device.
Method 3: How to Verify the Authenticity of an Aadhaar Number
Are you a landlord renting an apartment to a new tenant? Or an employer verifying a new hire's identity documents? Fraud is a real concern, but you can easily do an Aadhaar card check online by number to ensure the document handed to you isn't fake.
- Go to the UIDAI portal and click "Verify an Aadhaar Number".
- Enter the 12-digit UID provided to you by the individual.
- Enter the Captcha and proceed to verify.
If the number is legitimate, the system will display a confirmation message alongside the cardholder's age band (e.g., 20-30 years), gender, state of residence, and the last three digits of their linked mobile number. If the system throws an error, the Aadhaar number is invalid or forged.
No Internet? How to Check Your Aadhaar Status Offline
Technology fails us sometimes. If the UIDAI servers are experiencing downtime or you find yourself without internet access, you can still track your application status offline:
- Toll-Free Helpline (1947): Dial 1947 from your registered mobile number. Follow the Interactive Voice Response (IVR) instructions, or choose to speak directly to a UIDAI executive. Make sure to keep your EID or URN handy before you call!
Crucial Next Step: Fixing the 'Validity Unknown' Signature Error on Your Downloaded e-Aadhaar
Congratulations! You checked your status, found out your Aadhaar is successfully generated, and you've downloaded your e-Aadhaar PDF. But wait—when you open the file, you see a frustrating yellow question mark symbol hovering over the digital signature reading "Validity Unknown".
This is an extremely common, yet infuriating issue. Official e-Aadhaar PDFs are digitally signed by UIDAI, but most modern PDF readers (especially default apps on mobile phones) do not automatically recognize the government's root certificate. Submitting an Aadhaar printout with an unverified yellow question mark or a red 'X' can lead to your identity document being outright rejected by banks, passport offices, and telecom providers.

Traditionally, fixing this error requires transferring the PDF to a desktop computer, downloading Adobe Acrobat Reader, hunting down government root certificates, and manually validating the signature—a tedious, technical process that leaves many people frustrated and stuck.
Enter AadhaarVerify.com. This incredibly handy platform is the ultimate shortcut for anyone struggling with e-Aadhaar PDF signature errors.

Frequently Asked Questions (FAQs)
Can I check my Aadhaar status by name and date of birth only?
No, you cannot check the generation status of your Aadhaar application using just your name and date of birth. You must have your Enrolment ID (EID) or Update Request Number (URN) to track the process. However, as explained in Method 2, if you simply lost your existing Aadhaar number, you can use your name and mobile number to retrieve the UID via SMS.
How many days does it take to get a new Aadhaar card?
Typically, it takes anywhere from 15 to 30 days for a brand-new Aadhaar card to be generated after your initial enrolment at the Aadhaar Seva Kendra. Minor demographic updates (like a change of address) usually process faster, taking about 7 to 15 days.
Can I link my mobile number to my Aadhaar online?
No. Linking a new mobile number or updating your existing one requires strict biometric authentication (a fingerprint or iris scan). Therefore, you cannot do this online. You must physically visit an authorized Aadhaar Seva Kendra, a partnered bank, or a post office to update your phone number.
What should I do if my Aadhaar status says 'Rejected'?
If your status shows up as rejected, it usually means there was a demographic data mismatch, poor biometric capture, or it triggered a duplicate enrolment error. In this scenario, you will need to book a new appointment and re-enrol at an Aadhaar center free of charge.
