How to Find or Transfer Your BIR RDO Code

Your RDO is the BIR office that holds your records. Here is how to find your code and move it when you change address or employer.

Step by step

1. Find your current RDO codeCheck an old BIR form (1901, 1902, 1903, 1904 or a previous 1905 — the code is usually at the upper right). You can also call the BIR Customer Assistance Division or use the RDO Finder to see the office currently on record.
2. Identify the correct destination RDODetermine which district office covers your new residence or business address using the BIR directory. If your address is near a boundary, confirm jurisdiction with the proposed new RDO before filing.
3. Get the current BIR Form 1905Download the latest Form 1905 (revised October 2025) from bir.gov.ph. Fill in your TIN, current RDO code, registered name, the reason for the update, and the old and new RDO codes with your complete new address.
4. File with the right office for your statusEmployees, EO 98 registrants and other non-business individuals generally file with the new RDO covering their residence, or through ORUS where available. Businesses usually begin at the old RDO, then complete requirements at the new one.
5. Attach any supporting documentsRequirements vary; businesses are often asked for proof of the new address (such as a lease, utility bill or permit). Confirm the exact checklist with the receiving RDO, as it changes.
6. Confirm the transfer went throughAfter processing, verify your records now show the new RDO (for example on your next transaction or via the hotline) before filing returns tied to the new office.

What an RDO is, and why its code follows you

The Bureau of Internal Revenue divides the country into Revenue District Offices, and every taxpayer is assigned to one of them. Your RDO is the office that physically holds your registration records, and its code is a short number that identifies that office on your paperwork. It may feel like a trivial detail, but it is not. File a return or pay a tax while your record sits in the wrong RDO and you can run into rejected filings, misapplied payments and the slow, tedious work of untangling them. Knowing your RDO code, and keeping it aligned with where you actually live or operate, is quietly one of the most useful pieces of tax housekeeping you can do.

Finding the code you have now

There are three reliable ways to discover your current RDO code. The simplest is to look at an old BIR form: your original registration form, whether it was 1901 for the self-employed, 1902 for employees, 1903 for corporations or 1904 for one-time and EO 98 registrants, generally shows the code at the upper right, as does any Form 1905 you filed before. If you cannot find a form, you can call the BIR Customer Assistance Division and ask. The Bureau also offers an RDO Finder that shows the office currently on record for you. Bear in mind that the Finder tells you where your record sits, not necessarily where it ought to be, so it answers the question of your current RDO rather than your correct destination.

Transferring with Form 1905

When you move house, relocate your business, or simply discover that your record is in the wrong place, the instrument for fixing it is BIR Form 1905. This same form corrects an incorrect assignment and moves your registration from one RDO to another. The form was revised in October 2025, so use the current version from bir.gov.ph. On it you enter your TIN and current RDO code, your registered name, the reason for the update, and crucially the old and new RDO codes along with your complete new address. Before you fill it in, work out which district office actually covers your new address using the Bureau’s directory, and if you are near a boundary, confirm jurisdiction with the office you believe is correct so your transfer does not stall.

Where you file depends on who you are

The filing route is not the same for everyone. Employees, EO 98 registrants and other individuals who are not in business generally file the transfer with the new RDO covering their residence, and in some cases through the online update system where it is available. Businesses, by contrast, usually begin the process at the old RDO before completing requirements at the new one. If you are only changing address within the same RDO’s territory, you do not need a transfer at all; you simply update your address, still using Form 1905. And if you have changed jobs, do not assume anything happens automatically: your TIN does not migrate to a new employer’s RDO on its own, and you must request the move yourself.

The online question

Whether you can complete an RDO transfer entirely online is genuinely unsettled in public guidance. Some sources describe transfers as something handled only through an RDO, while others point to a registration update sheet available inside the Online Registration and Update System that allows the change to be started online. Because the picture keeps shifting as the Bureau digitises more of its services, the honest answer is to confirm the current route on bir.gov.ph or by calling the BIR hotline before you assume one way or the other. Requirements for supporting documents, especially for businesses, also vary, so check the exact checklist with the receiving office.

A quick reality check on timing

Transfers are not always instantaneous, and that lag catches people out. If you move your record and then immediately try to transact against the new office, you may find the change has not fully propagated yet. Where a deadline is approaching, it is wise to initiate the transfer well ahead of time rather than on the day you need to file, so the processing window does not collide with a due date. If you are uncertain whether the move has completed, a short call to the hotline or a check on your next transaction settles it before you commit to a filing.

Confirm, and stay cautious

After you file, it is worth verifying that your record actually shows the new RDO before you lodge any return tied to it, whether by checking on your next transaction or by asking the hotline. Throughout, keep your guard up: no legitimate agent needs your TIN together with a password or a one-time code to move your record, and the Bureau does not charge a hidden fee to process a transfer. Anyone offering a paid express transfer through a private chat is best ignored.
