How to Verify & Check Tin Number Online Philippines [2023]?

Verifying and checking a Tax Identification Number (TIN) online in the Philippines is a straightforward process that allows individuals and businesses to confirm the validity of their TIN or that of others. The TIN serves as a crucial identification number for tax purposes, and online verification provides a convenient way to ensure accurate tax reporting and compliance.

In this digital age, the Philippine government has made it easier for citizens to access this information online, saving time and effort in the verification process. In this article, we’ll guide you through the process of checking and verifying your TIN online by name using two different methods – the BIR website and the BIR Mobile TIN Verifier app.

Steps to Check TIN Number Online

Here are the two methods to check TIN number online.

Method 1: Check via BIR Website

The BIR website offers a eRegistration (eREG) process that helps people and businesses get a Taxpayer Identification Number (TIN), pay the fee, and get a Certificate of Registration. It also has a feature called eReg TIN Query, which lets you check your basic info like your name, birthday, TIN, and where you deal with taxes (called the Revenue District Office or RDO).

But here’s the thing: you can only use this feature if you have a special account. That means you need to know someone who works at the BIR or has access to the eReg system. If you do, you can ask them to help you check your TIN online.

Here’s how you can verify your TIN number online using the BIR website:

  1. Visit
  2. Check the option on the site “TIN Query Login” on the main page.
  3. If you already have an authorized user account, go ahead and enter your login details. If you don’t, you’ll need to ask someone who does to log in for you.
  4. Once you’re logged in, you’ll see a search box. Enter your TIN number there and then click the search button.
  5. The results will display important information, including your name, address, business type, and RDO code.

  5. The app will then display the results, showing your TIN number and your RDO code, along with your current status (whether it’s active or inactive).
