Contact your current or previous employer to request your TIN. The HR or admin department of the company you’re working for keeps your employment records, including your TIN. So for sure, they can help you retrieve your forgotten TIN.

Don’t forget to dial the area code 02 before the numbers (e.g., 0289817000) if you’re calling outside Metro Manila or the country code +63 when you’re calling from another country.

Before speaking with a customer service agent, be ready with your details that might be asked for verifying your identity such as full name, address, and birthdate.


4. Send an email inquiry to the BIR.

If the need to recover your TIN isn’t that urgent or you can’t get through the BIR hotlines, you can inquire about your TIN through email.

Email your TIN verification request, along with your complete name, address, and birthdate, to [email protected]
