What Is the BIR Certificate of Registration (COR / Form 2303)?
The BIR Certificate of Registration (COR), also known as BIR Form 2303, is the official document issued by the Bureau of Internal Revenue (BIR) that authorizes a taxpayer — whether an individual, professional, or business — to legally operate and transact business in the Philippines. It serves as proof that your business is registered with the BIR and is authorized to issue official receipts, file tax returns, and pay the correct taxes.
The COR contains key information including your Taxpayer Identification Number (TIN), registered taxpayer name, business address, Revenue District Office (RDO), tax types you are registered to file, and the date of registration. It must be displayed prominently at your place of business and renewed annually or whenever there are changes to your registration details.

Government Transactions
