How to Apply for TIN or Recover a Lost TIN from BIR

The Tax Identification Number (TIN) is very important for all taxpayers, whether you personally own a business or work for some company. This is one of the top requirements for starting a business, no matter what business you may be involved in – on or before you start your operations!

The issuance of TIN is free of charge. Different entities might require different TINs; thus, it is advisable that you bring all necessary documents pertinent to your business and your company before you head off to the Bureau of Internal Revenue (BIR).

There are two ways you can apply for the TIN. The usual method is going to the nearest BIR to file your application but many are now using the second method because it is more convenient: Online Registration!

Visit the BIR eReg website for Online TIN Registration. Server errors are known to occur because of the high volume of users; thus, we advise you to be patient and re-check after a couple of minutes for the link to be available.

Here’s a guide that you can follow to Register TIN Online.

If this online option does not work for you, better apply for the number at a physical BIR office.

For more information, check out the comprehensive guide released by BIR: Index for Application for Taxpayer Identification Number (TIN).

How to Recover a Lost or Forgotten TIN

Although separate TINs are issued for companies owned by individuals and corporations, only one TIN must be used by the same company or individual. Remember, it is a criminal offence to own more than one TIN!

So, if you have forgotten what your TIN is, do not apply for a new one!

Simply call BIR trunkline at (02) 981-8888. You need to provide the BIR personnel on the line with pertinent information like your complete name and birthday before you are given your lost TIN.

Or you can email them at [email protected] Below are sample email message provided by Hannah Faith;

  1. Hi, I remember filing for my TIN number years ago but couldn’t exactly remember if my application had been accepted or denied.

    Now I’m practically not sure if I do have one… Can anybody help me to confirm if wether I do or do not have a TIN number and if so, is it possible if I could get a hand in recovering it?

    Looking forward to anybody that could help me out, it’ll be greatly appreciated and I’d like to thank you in advance to those who are willing to help…

  2. Good day to you,
