Philippines TIN number guide

Taxpayer Identification Number (TIN)

The Taxpayer Identification Number (TIN) is an automatically generated reference identification code distributed by the Bureau of Internal Revenue (BIR) to each person enrolled in its comprehensive database. This unique ID contains vital data points required for efficient computer processing and informative report creation.

TIN Format

The distinctive Taxpayer Identification Number (TIN) utilized by the high-volume Philippine taxation system consists of a 9-12 digit all-numeric code, unlike the alpha-numeric Taxpayer Account Number (TAN), enabling more seamless digital processing.

As an example, examine the following TIN format: 000 – 123 – 456 – 001. The initial digit "0" indicates incorporation of a business entity. The subsequent 2nd to 8th digits "00-123-45" comprise a sequential order for streamlined tracing within the extensive database. The 9th digit "6" represents the integrated check number for accurate validation. Thefollowing 10th to 12th digits "001" signify the designated branch code for efficient categorization. Finally, the "000" prefix denotes a pre-generated TIN issued from the vast numbering sequence for prompt identification by the Bureau of Internal Revenue (BIR) across the populous country.
