I forgot my TIN. Can I just apply for a new one?

No. You are allowed only one TIN for life, so you must recover the existing number instead of applying again. Applying for a second TIN can lead to penalties.

Where can I find my TIN without going to the BIR?

Check old payslips, your BIR Form 2316, past tax returns, official receipts, or your TIN card. Many people find their number on one of these.

How do I recover my TIN from the BIR?

Use an official channel such as the BIR TIN Verifier app, your ORUS account, the BIR contact center, or a visit to your RDO with a valid ID.

How to Recover a Lost or Forgotten TIN

TIN2 min readUpdated May 30, 2026

Forgetting your TIN is common, especially if it was issued years ago by a past employer. The important thing is that you recover the old number rather than apply for a new one. Here is how.

First rule: do not apply again

Each person is allowed only one TIN for life, and holding more than one is against the law, with possible penalties. So if you cannot find your TIN, the goal is to recover the one you already have, not to register a fresh one.

Where to look first

Before contacting the BIR, check documents that usually carry your TIN:

Old payslips or your BIR Form 2316 from a previous employer
Your Certificate of Registration if you have a business
Past tax returns or official receipts
Your TIN card, if you were issued one

How to recover it through the BIR

If you still cannot find it, use an official BIR channel: the BIR TIN Verifier mobile app, your ORUS account, the BIR contact center, or a personal visit to your Revenue District Office with a valid ID.

Ask AskOnward for the current steps and what identification you need to recover your TIN.
