TIN Verifier Mobile Application: Taxpayer’s Identification Number (TIN) Inquiry and Validation at Your Fingertips

All of us are adapting to the new normal. The extended lockdown in the country allowed private and public businesses to innovate to serve their customers continuously.

Recently, the Bureau of Internal Revenue (BIR) launched its online TIN verification channel.

The BIR TIN Verifier Mobile Application allows taxpayers to validate their TIN online or inquire about their TIN application status using their mobile phones. A BIR agent will act on their request and will answer accordingly based on available BIR records.

How to use the BIR mobile application


  1. Download the app from the Google Play Store or the App Store;


  1. Read the bureau’s Privacy Notice and tick the “I have read and understood the Privacy Policy” and “Proceed” buttons;


  1. The app will direct you to the Home Page. Tap the “TIN Verifier” button and select your desired transaction- TIN inquiry or TIN validation;


  1. Fill-up the required information;


  1. You will receive a confirmation message that your TIN is verified;


  1. You may screenshot the message for your reference.


Additional Information


  1. Currently, the app is available during weekdays, Monday to Friday, from 8:00 AM to 5:00 PM;


  1. The TIN verification process is not yet fully automated. The BIR agents still manually check the TIN records of the taxpayer before they can answer your transaction.  So, response time may be slow;


  1. Walk-in TIN transactions are still accepted in the Revenue District Offices (RDOs) to serve taxpayers with no access to online service.


The BIR mobile application is still in its initial stage. It needs fine-tuning to make it more useful and convenient for taxpayers. The new system is a step ahead than queuing in the RDOs.
