Tax Deduction and Account Collection Numbers (TAN) is a number allotted to entities that deduct tax. It can happen that a company or individuals responsible for deduction of tax have inadvertently ended-up with two TAN Numbers.
It is important to point out that if a company or entity has various branches they are free to use two different TAN numbers. In case by mistake two are alotted, you should use the one that is often being used.

How to surrender he duplicate or the second TAN?
There is a procedure by which you can surrender the second one. You need to decide on which TAN you want to surrender. You must give-up the one that was not being used regularly.

You cannot file TDS without TAN number?
TAN is extremely important to deposit the tax deducted at source of TDS. You cannot deposit the E TDS without the TAN.
Also you cannot quote PAN in place of TAN. In all cases the later is necessary when you wish to deposit the TDS.
What If You Wish to Correct The TAN Related Data?
You can also correct your address and other related data, if you so wish. The Income Tax authorities can correct the same, after you fill the form which shows the correction for TAN Data.
We wish to reiterate once again that you must quote the TAN, whether you are filing TDS and TCS or whether you are filing through paper or in the electronic form.
