How to Find Your Registered BIR RDO (Philippines)

Your Revenue District Office (RDO) is the Bureau of Internal Revenue office that keeps your tax registration record. It matters because your RDO controls where you: file registration updates, transfer your TIN record, register books/POS, get your Certificate of Registration, and process many clearances. Here’s a complete, practical guide—where to see your RDO, how to confirm it if you’re unsure, and what to do if you need to transfer it.

1) Quick ways to see your RDO code/name

Check these documents and systems you may already have:

BIR Form 2303 (Certificate of Registration) – Front page lists your RDO Code and office name (for businesses/self-employed/mixed income).
eBIRForms Profile – Open the Profile/Taxpayer Information panel of eBIRForms; the RDO Code field shows your current RDO.
BIR eREG or welcome email/SMS (for newly registered taxpayers) – Often states your assigned RDO.
BIR Form 1901/1902/1903/1904/1905 copies – Any stamped/received registration form you filed will indicate the RDO that processed it.
BIR Form 2316 (for employees) – Usually shows the employer’s RDO and often the employee’s RDO if the employer registered you; if they processed your BIR Form 1902, your RDO is typically the same.
Old TIN verification slip/acknowledgment notice – If you’ve ever requested TIN verification, the printout identifies your RDO.
Employer’s HR/Payroll (for current employees) – If HR processed your 1902, they can tell you the RDO where they registered you.

Tip: RDO “code” is a 3-digit identifier (e.g., 043) paired with an RDO name (e.g., “Pasig”). Use the code when filling eBIRForms or registration updates.

2) If you don’t have any documents: how to confirm your RDO

Because of data privacy, BIR won’t freely disclose taxpayer data over casual phone/email. These are compliant ways to confirm:

In person: Visit any BIR office/Taxpayer Service counter and request TIN/RDO verification. Bring a government ID and your TIN. If you only know your name/birthday, they can search and confirm after identity checks.
Through an authorized representative: Send your representative with (a) your signed authorization or Special Power of Attorney, (b) your ID copy, and (c) their original ID.
Through BIR’s official verification channels/apps: Use the BIR-provided verification channel to confirm your RDO code after identity checks (follow the app’s or channel’s instructions for selfies/ID upload or live chat, as applicable).

3) Who assigns your RDO in the first place?

Employees (pure compensation): Usually the employer’s RDO that processed your BIR Form 1902. If you changed employers without transferring your RDO record, your RDO can still be the old employer’s RDO.
Self-employed/Professionals/Mixed income: Place of business (or residence if no fixed place) via BIR Form 1901.
Non-individuals (corporations/partnerships): Principal place of business (Head Office) via BIR Form 1903; branches get separate RDOs.
Estates/Trusts/OCWs/Non-resident citizens: Assigned per the registration rules applicable to those taxpayer types (e.g., last residence of decedent for estates, residence of trustee, etc.).

4) When and why you might need to transfer your RDO

You moved residence (individuals) or moved your principal place of business (non-individuals).
You switched from employee to self-employed (or vice versa) and need the RDO that covers your business address.
Your employer changed RDO and you want your record aligned.
You have multiple registrations (e.g., old 1902 at Employer A’s RDO, then registered 1901 at residence RDO); unifying avoids filing conflicts.

5) How to transfer your RDO (BIR Form 1905)

Form: BIR Form 1905 – Registration Update/Correction/Cancellation Where to file: Generally with the “old” (current) RDO that holds your record (so they can transfer it to the “new” RDO). If you’re unsure which office is “old,” ask any BIR help desk after identity checks.

Core steps (individuals):

Fill out 1905 – Tick “Update of Registration Information” → “Transfer of Home RDO” (or “Transfer of Business RDO” as applicable).
Attach valid ID and proof of new address (e.g., lease, utility bill, barangay cert)—requirements vary by office; bring originals and photocopies.
Submit to old RDO. Keep the stamped copy.
Wait for inter-RDO transfer posting, then transact at the new RDO.

For self-employed/professionals:

If also updating trade name/business address, tick the corresponding boxes; if you moved city, your books of accounts and OR/Invoice “Authority to Print”/POS registration may likewise need updates in the new RDO.

For non-individuals (corporations/partnerships):

Board Resolution/Secretary’s Certificate authorizing the address change, plus DTI/SEC filings (Amended GIS/Articles if address change is material), updated Mayor’s/Lease, etc. Submit 1905 at the old RDO (Head Office), and file branch updates if branches are affected.

If you’re already in the “new” city: Some RDOs accept walk-in assistance to route your 1905 to the old RDO. Bring IDs and proofs; practices vary.

6) Special cases & pitfalls

Two TINs (duplicate) – The law allows only one TIN. If you discover duplicates (common after job changes or OFW registration), go to the RDO and request cancellation/merging using 1905, with an affidavit and IDs. Do this before any transfer to avoid mismatches.
Employee turned freelancer – If you begin freelancing while your record sits at your employer’s RDO, file 1905 to transfer to the RDO of your business address, and register your books, ORs/Invoices, and tax types via BIR Form 1901/0605 as instructed.
Head office vs branches – Head Office stays with its RDO; each branch registers in the RDO of its location via BIR Form 1903/1905 and gets its own ATP/POS registration and Permit to Use.
eFPS/eBIRForms enrollment – Your RDO code must match your enrollment record. If eBIRForms throws RDO/registration errors, confirm your RDO and file 1905 if it’s outdated.
Estate and trust accounts – Transact in the RDO tied to that taxpayer account (estate/trust), not the administrator’s personal RDO.

7) What you can do at your RDO (why accuracy matters)

Register/Update (1901/1903/1905), books of accounts, ATP/POS, additional business lines/branches
Secure: Certificate of Registration (2303), certified copies, TIN verification, closure/suspension processing
File: Certain rulings or requests routed through the district
Get: Taxpayer education and frontline assistance, docket status, some clearances/endorsements

If your record sits in the wrong RDO, you’ll experience delays (e.g., ATP or POS approval) or system mismatches (eFPS/eBIR).

8) Document checklist

To verify your RDO

Government ID
TIN (if known)
Any old BIR form showing your details (optional but helpful)

To transfer RDO (individuals)

BIR Form 1905 (2–3 copies)
Valid ID (original + photocopy)
Proof of new address (lease, utility bill, barangay cert, deed, etc.)
If represented: SPA/authorization letter + your ID copy + representative’s ID

To transfer RDO (non-individuals)

1905, Board Resolution/Secretary’s Certificate
SEC/DTI address-change filings (as applicable)
Lease/Title, updated Mayor’s/location clearances

9) Frequently asked questions

Q: Can I file a return in any RDO while waiting for transfer? A: eBIR/eFPS returns can still be filed electronically, but for on-site services (books registration, ATP, POS), your RDO of record governs. Align your RDO early.

Q: My employer says my RDO is theirs, but I moved cities. Do I need to transfer? A: If you remain pure compensation, you can stay at your employer’s RDO. If you’ll register as self-employed/mixed income or need local services (books, ATP), transfer to your business address RDO.

Q: I lost my 2303. How do I know my RDO? A: Request TIN/RDO verification with ID; once confirmed, you can apply for a replacement 2303 at your RDO.

Q: Can I learn my RDO over the phone? A: Because of data privacy, you’ll usually be asked to verify identity through official channels or appear in person.

10) Step-by-step: If you’re totally unsure of your RDO

Gather your TIN, ID, and any BIR document you still have (2316/2303/190x).
Go to the nearest BIR help desk and request TIN/RDO verification.
If the record is in a far RDO and you need services locally, fill BIR Form 1905 to transfer.
After transfer posting, re-enroll/update your eBIR/eFPS profile to reflect the new RDO code.

11) Bottom line

Your RDO anchors your BIR life—know it, keep it updated, and transfer it when your residence/business changes.
The fastest proofs are your 2303, eBIRForms Profile, and stamped 190x forms; if you have none, use official verification with ID.
Use BIR Form 1905 to transfer, and align your books, ATP/POS, and eBIR/eFPS records to the correct RDO to avoid processing snags.
