Lost or Forgot TIN Number
Losing track or forgot TIN number is more common than you think. Whether you never wrote it down after your first BIR registration, lost your TIN card, or simply have not needed it in years, forgetting your TIN does not mean you have to apply for a new one. Your TIN is permanent and it is still in the BIR database. You just need to retrieve it through the right channel.
Your TIN is permanent and never expires. Retrieval is completely free through official BIR channels. No need to start over — we’ll show you the fastest way to get it back.
WARNING: Do Not Apply for a Second TIN
Under Section 275 of the National Internal Revenue Code, possessing multiple TINs is punishable by a fine of up to PHP 50,000 and/or imprisonment. Always recover your existing TIN instead.

The BIR representative will verify your identity through these details before verbally confirming your TIN. BIR hotlines operate Monday to Friday, 8:00 AM to 5:00 PM (PHT).

Steps for walk-in TIN retrieval:
Important note: Under RMC 31-2024, RDOs are no longer authorized to issue manual TIN Verification Slips for employment purposes. If a company’s HR department asks for a TIN Verification Slip, direct them to use the ORUS TIN Verification Tool instead.

This is the fastest method if the document is still accessible.

BIR is required by law to handle your personal information securely and only for its intended purpose.
Verification, not surveillance
The selfie requirement exists solely to confirm your identity — it is not stored beyond the verification process.
