What Is an RDO and Why Does It Matter?
Before anything else, it’s important to know what an RDO does. Your BIR Regional District Office (RDO) is responsible for maintaining and updating your tax records. All your tax-related activities — from registration to filing to requesting documents — must be connected to the RDO you are assigned to.
Your RDO affects:
- Where you request your TIN verification
- Where you file certain tax-related documents
- Processing of COR (Certificate of Registration)
- Business registration and closure
- Updating marital status, address, or employment
If you go to the wrong RDO, they’ll redirect you — which means wasted time, longer queues, and repeated trips.
How to Know Your Assigned BIR RDO
1. Call the BIR Hotline
Dial 8538-3200 and request your RDO by providing your full name, birthdate, and TIN.
2. Check Your Old 2316 or COR
These documents usually show your RDO code in the upper section.
3. Visit Your Nearest RDO
If you’re unsure or your records are outdated, visiting the nearest BIR branch can confirm your assigned RDO.
