Quick answer: Linking compares the two names character by character, so a middle name on one card and not the other, an extra space, or one different letter is enough to fail it. Correct the record that is genuinely wrong, not the one that is easier to change. In most cases that is the PAN, because a PAN correction is done online, costs a small fee and has no limit, while an Aadhaar name update is a counter visit and spends one of only two you get for life. Left unlinked, a PAN can become inoperative, which is why this is worth settling promptly.
The unhelpful part of this problem is the error message. It says the details do not match and stops there, so people begin guessing: maybe the date of birth, maybe the spelling, maybe the father's name. Almost always it is the name, and almost always the difference is small enough that a human reading both cards would not notice it. The system is not reading like a human.
At a Glance
| How the check works | Character by character, not by meaning |
| Commonest cause | A middle name on one card and not the other |
| Next commonest | An initial expanded on one and abbreviated on the other |
| The decision | Which record is actually wrong |
| PAN correction | Online, small fee, no limit on how often |
| Aadhaar name update | Counter visit, and two for your whole life |
| So usually fix | The PAN, unless the PAN is the correct one |
| If left unlinked | A PAN can become inoperative |
Key Takeaways
- The failure is nearly always a small name difference, not a serious discrepancy.
- Decide which record is wrong before deciding which is convenient to change.
- PAN corrections are unlimited; Aadhaar name updates are capped at two for life.
- Look at what your other documents say, because that settles which version is right.
- An unlinked PAN can stop working, so this is not a problem to postpone.
Commonest Differences: Quick Facts
| Middle name present on one card only | The single biggest cause |
| Initial versus expanded name | K. Sharma against Krishna Sharma |
| Extra or missing space | Invisible to you, fatal to the check |
| Spelling variant | Sunil against Suneel |
| Surname order | Recorded differently on each card |
| Married name on one only | Common after a wedding |
| Father's name in the name field | An older enrolment habit |
| Date of birth difference | Less common, and a heavier fix |

Why It Failed
That is why the error feels absurd when you hold both cards and they look the same. Read them letter by letter, including the gaps, and the difference is usually obvious within a minute. Write both names out on paper exactly as printed before doing anything else.
Which Record Is Wrong
The decision the whole fix turns on, and people rush past it.
- If your marksheet and birth certificate agree with the PAN, the Aadhaar is the wrong one, whatever the inconvenience of fixing it.
- If they agree with the Aadhaar, correct the PAN, which is the easier case and also the commoner one.
- If your documents are split, you have a wider problem than linking, and it is worth resolving properly rather than patching one pair.
- After a marriage, the married name usually belongs on both, and the sequence is Aadhaar first then PAN.
Why the PAN Is Usually the Cheaper Side
| PAN correction | Aadhaar name update | |
|---|---|---|
| Where | Online, from home | A Seva Kendra, in person |
| Cost | A small correction fee | A nominal counter fee |
| Limit | None | Two for your whole life |
| Speed | An e-PAN within days | Days to a few weeks |
| Number changes? | No | No |
That lifetime limit on Aadhaar is the reason we push people to check carefully. Spending one of two updates to fix a linking error, when the Aadhaar was correct all along and the PAN was wrong, is an expensive way to solve a cheap problem. The limit and the route past it are on our two-update page.
Fixing It, Step by Step
Write both names out exactly as printed
Letter by letter, including spaces. The difference is usually visible within a minute once you do this.
Check what your older documents say
Birth certificate, Class 10 marksheet, passport. The version most of them carry is the correct one.
Correct whichever record is wrong
PAN online through the official portal, or Aadhaar at a Seva Kendra if the PAN is the correct one.
Wait for the correction to reflect
Days for an e-PAN, and days to a few weeks for Aadhaar. Do not attempt linking before it shows.
Try the link again
On the income tax portal, once both records read identically.
Keep the corrected card and the old one
Because the pair explains the history at any later verification.
If the correction itself is refused, that is a different problem, and the PAN route is covered on our PAN guide with the Aadhaar counter on our Seva Kendra guide.
When It Is the Date of Birth Instead
- Less common, and heavier, because a date update on Aadhaar is allowed only once in a lifetime rather than twice.
- Check the birth certificate first, since it is the record both others copied from and the one any office compares against.
- Correct the certificate before either card if it is the certificate that is wrong, because otherwise the mismatch simply reappears.
- A gazette cannot help with a date, at any stage, so nobody should be quoting one for this.
The full route is on our Aadhaar date page and our date of birth guide. It is worth reading before spending the single update.
What Happens If You Leave It
So this belongs on the list of things worth finishing rather than tolerating. It is also among the cheapest problems on this website to solve, since in the common case it is one online correction and a fee of a few hundred rupees.
Central Gazette: the Complete Process and File Format
Our core service: most linking failures need no gazette at all. Where the underlying issue is a genuine name change rather than a mismatch, this is the filing as we run it from Lucknow.
Stage 1: The affidavit
This is the one-and-the-same wording, not a name change declaration, and it is what a bank or an employer may ask for while the correction is being processed. It is a bridge rather than a fix, and the correction itself still has to be made.
Stage 2: The Public Notice, in two copies
Each witness gives signature, full name and address, and both sign both copies at one sitting.
Stage 3: The CD and CD-Certificate
Stage 4: Newspapers, fee, covering letter and dispatch
Publish in two newspapers and buy four copies
One Hindi daily of your district and one English paper. Two copies of each edition, since the passport counter asks for complete pages later.
Pay Rs 1,100 on BharatKosh
Before the envelope is sealed, with the function head, PAO and DDO checked on the confirmation screen and two receipts printed.
Write the covering letter
To The Controller, Publication Department, Civil Line, Delhi 110054, saying the formalities are complete and the documents are enclosed, with your mobile number and email.
Assemble, check and photocopy
Affidavit, Public Notice in two witnessed copies, CD with CD-Certificate, both newspaper pages, identity and address proof, photographs and the receipt.
Courier it, tracked
One to three days from most UP districts, with no counter to visit.
Publish, download, then Aadhaar, then PAN
Twenty-five to forty-five days, then the download, then Aadhaar, and PAN after it so the link succeeds first time.
Aadhaar First, PAN Second, Link Third
This is the same sequence used across the whole update journey, and it exists for exactly this reason. The full ordering is on our update order page.
Gazette Fees, Time and the File
| PAN correction | The standard online correction fee |
| Aadhaar name update | A nominal Kendra fee; one of two for life |
| Affidavit, where a bank asks for one | Rs 100 to 500 including stamp paper and notary |
| Adult gazette fee, only for a real change | Rs 1,100 on BharatKosh |
| Newspaper advertisements | A few hundred rupees per paper |
| Typical linking fix | Usually only the PAN correction fee |
| Publication window | 25 to 45 days, where a gazette applies |
The envelope in one line, where publication is genuinely needed: covering letter with your phone and email, affidavit (notarised), Public Notice typed in two copies with two witnesses on each, CD in MS-Word format with the signed CD-Certificate, both complete newspaper pages, photo identity proof, address proof, photographs and the BharatKosh receipt.
Before You Correct Anything: Check These
- Write both names out exactly as printed, including spaces.
- Check your birth certificate and marksheet to see which version is correct.
- Remember the Aadhaar name allowance is two for a lifetime.
- Do Aadhaar before PAN wherever a real name change is involved.
After the Gazette: What Updates Next
Once the link succeeds, check that your bank and employer records carry the same version, since they were often opened from whichever card was to hand. Keep the corrected card together with the older one, because the pair explains the change at any later verification and saves an argument.
What Other Websites Get Wrong
- Wrong: change whichever card is easier. Right: change the one that is actually wrong, or you make the error permanent.
- Wrong: Aadhaar can be updated freely. Right: two name updates for your whole life, so do not spend one carelessly.
- Wrong: the mismatch must be serious. Right: an extra space is enough to fail the check.
- Wrong: fix PAN first because it is quicker. Right: Aadhaar first where a real name change is involved, or the link fails again.
- Wrong: an affidavit fixes the link. Right: it is a bridge for a bank; the correction still has to be made.

Why We Ask for Both Names in Writing
On a linking call we ask people to type out both names exactly as printed rather than describe them, because the difference is usually a space or a middle name and nobody notices it while speaking. Once we see the two strings, the answer is normally obvious and often costs a few hundred rupees. Vipin Chauhan, B.Tech LL.B, checks the older documents before recommending which side to correct.
- We compare the two strings letter by letter: which finds the cause in a minute.
- We check your marksheet and birth certificate: since they decide which version is correct.
- We protect the Aadhaar allowance: because you only get two for life.
- We do not add a gazette to a mismatch: which needs no publication at all.

PAN and Aadhaar Name Mismatch: FAQs
Why does linking fail when both cards look the same?
The check compares the two names character by character. A middle name on one card only, an initial against an expanded name, or even an extra space is enough to stop it.
Which record should I correct?
The one that is actually wrong, not the one that is easier. Check your birth certificate, Class 10 marksheet and passport; the version most of them carry is the correct one.
Why is the PAN usually the cheaper side?
A PAN correction is done online, costs a small fee and can be repeated. An Aadhaar name update is a counter visit and spends one of only two you get for your whole life.
What is the commonest cause?
A middle name present on one card and absent on the other, followed by an initial on one and the expanded name on the other.
Can an affidavit fix the link?
No. A one-and-the-same affidavit is a bridge a bank or employer may accept while you wait, but the correction still has to be made.
Does my PAN number change?
No. Neither number changes; only the name printed on the record does.
What if it is my date of birth that differs?
Heavier, because Aadhaar allows a date update only once in a lifetime. Check the birth certificate first, since it is what both others copied from.
Can a gazette fix a linking failure?
No, and it is not needed. This is a mismatch rather than a name change, so nobody should be quoting you for publication.
I am changing my name properly. What order do I use?
Gazette, then Aadhaar, then PAN, then link. Doing PAN before Aadhaar makes the link fail for a new reason.
What happens if I never link them?
The PAN can be treated as inoperative, which affects filing returns, claiming refunds, deduction rates and some account operations.
How long does the fix take?
Days for an e-PAN after an online correction, and days to a few weeks for an Aadhaar update. Wait until it reflects before trying to link again.
What should I do first?
Write both names out exactly as printed, including spaces. The difference is usually visible within a minute, and it tells you what you are actually fixing.
Official Sources
- Income Tax Department linking requirements, under which an unlinked PAN may be treated as inoperative.
- PAN correction procedures through the authorised online service providers.
- UIDAI's update framework, under which a name may be updated twice and a date of birth once in a lifetime.
- The Department of Publication's guidelines for change of name, where a genuine change rather than a mismatch is involved.
Facts here are checked against these sources and our own casework. Fees, deadlines and portal behaviour are revised periodically and should be confirmed; the character-by-character nature of the check is the stable part.
The Short Version
Linking compares the two names character by character rather than by meaning, so a middle name on one card only, an initial against an expanded name, or an invisible extra space is enough to stop it. Write both names out exactly as printed and the cause is usually obvious in a minute. Then comes the decision that matters: correct the record that is genuinely wrong rather than the one that is easier to change, because changing the correct card to match the incorrect one makes the error permanent. Your birth certificate and Class 10 marksheet settle which version is right. In most cases the PAN is the one to fix, since a PAN correction is online, cheap and unlimited, while an Aadhaar name update means a counter visit and spends one of only two you get for your whole life. Do not leave it unresolved, because an unlinked PAN can be treated as inoperative.
