Complete Directory of Puerto Rico Postal Codes

This means finding accurate Puerto Rico Postal Codes requires using standard 5-digit USPS ZIP codes. Use our updated 2026 directory below to find the exact routing number for any municipality or local address.
Understanding Puerto Rico Postal Codes and USPS Format
Because it is a US territory, all of its postal formats are logically grouped at the very beginning of the national USPS numbering system. Every valid code in this region starts with two zeros:
- 006xx: Primarily covers the western and northwestern municipalities (e.g., Aguadilla, Mayagüez).
- 007xx: Routes mail to the southern and eastern regions (e.g., Ponce, Caguas).
- 009xx: Exclusively assigned to the capital’s metropolitan area, including San Juan and its immediate surroundings.
