Yes, USPS does deliver to Puerto Rico, and it treats the island as a domestic destination. That means standard U.S. postage rates apply, every domestic mail class is available, and you don’t fill out customs forms. Addressing a package to San Juan works the same way as addressing one to San Diego, with one Puerto Rico-specific twist covered below.
Why Domestic Status Matters
USPS classifies mail to Puerto Rico as domestic mail because Puerto Rico is a U.S. territory. The Domestic Mail Manual confirms that mail originating in the United States for delivery to its territories is treated as domestic mail.1Postal Explorer. 608 Postal Information and Resources You pay domestic postage, skip the customs declaration, and drop the package off the same way you would for any stateside shipment.
Private carriers handle it differently. FedEx routes Puerto Rico shipments through its international services division and requires customs documentation, including a commercial invoice describing the goods, their value, and the country of manufacture.2FedEx Puerto Rico. Customs Documentation Support FedEx also applies tiered Out of Delivery Area Surcharges on Puerto Rico shipments ranging from $4.00 to $45.00 per shipment depending on the ZIP code.3FedEx. Puerto Rico Service and Rate Guide 2026 USPS charges none of that.

- Media Mail is the cheapest option for books, CDs, DVDs, and other educational media, though transit times run slower and vary.6USPS FAQ. What is Media Mail
Those delivery windows are USPS targets for the contiguous United States. Mail to Puerto Rico may land on the longer end of the range because it involves air or sea transport, and weather or holiday volume can push things further.7United States Postal Service Office of Inspector General.

How to Address Mail to Puerto Rico
Use “PR” as the state abbreviation, followed by the ZIP code. Puerto Rico ZIP codes start with 006 (northwestern part of the island), 007 (southeastern), or 009 (the San Juan metro area).8Postal Explorer. Publication 28 – Postal Addressing Standards
Include the Urbanization Line
Many Puerto Rico addresses include an “urbanization” name, which identifies a specific neighborhood, sector, or housing development within a city. It’s the extra line that helps the carrier find the right street in areas where street names repeat across developments. USPS Publication 28 places the urbanization line directly after the recipient’s name and before the street address, preceded by the abbreviation “URB.”9Postal Explorer. Publication 28 – Postal Addressing Standards – 292 Urbanization
A correctly formatted address looks like this:
MARIA RODRIGUEZ
URB VILLA VERDE
123 CALLE ROSA
SAN JUAN PR 00926-1234
Leaving off the urbanization name is one of the most common mistakes people make when mailing to Puerto Rico, and it’s often the reason packages get delayed or returned.
Air Transport Restrictions to Watch
Most mail to Puerto Rico travels by air, which matters when an item is restricted to surface-only transport. You can’t simply pick a slower service and have USPS truck the package to San Juan. If an item is barred from air, you’ll need a carrier that offers ocean freight or surface mail to the island.
Items restricted to surface transportation only include:
- Standalone lithium metal and lithium-ion batteries shipped without the device they power. Batteries installed in or packed with equipment can go by air, but only if each cell is rated at 20 watt-hours or less and each battery at 100 watt-hours or less.10Postal Explorer. USPS Packaging Instruction 9D – Lithium Metal and Lithium-ion Cells and Batteries Domestic
- Pre-owned, damaged, or defective devices containing lithium batteries, which are banned from air transport entirely. The outer packaging must be labeled “Restricted Electronic Device” and “Surface Transportation Only.”11USPS. Domestic Shipping Prohibitions, Restrictions, and HAZMAT
- Perfume containing alcohol, which cannot be shipped by air for domestic mail.11USPS. Domestic Shipping Prohibitions, Restrictions, and HAZMAT
- Hand sanitizer, since most formulations contain alcohol and are flammable.
- Safety matches, ground transport only within the U.S.
Plan around these before you’re standing at the counter. A gift box that includes a bottle of perfume or a used laptop simply cannot fly to Puerto Rico through USPS.
EEI Filing for Shipments Over $2,500
Shipments of goods valued over $2,500 per commodity type between the mainland and Puerto Rico require Electronic Export Information filed through the Automated Export System before shipping.12United States Census Bureau. Exports Between the United States and Puerto Rico Part 1 It feels like an international requirement bolted onto a domestic shipment, but the Foreign Trade Regulations treat movement between the states and Puerto Rico as an export for statistical tracking purposes.13eCFR. 15 CFR 30.2 – General Requirements for Filing Electronic Export Information
You file through the AESDirect portal at the Census Bureau’s website, which generates an Internal Transaction Number that serves as your proof of filing. For mail sent between the U.S. and Puerto Rico, that proof must be provided to the carrier by the time the shipment reaches the port of unlading.14eCFR. 15 CFR 30.4 – Electronic Export Information Filing Procedures, Deadlines, and Certification Statements Most personal shipments fall well under $2,500, so this primarily affects businesses and people moving expensive equipment.
Insurance and Filing a Claim
USPS domestic insurance applies to Puerto Rico shipments the same as anywhere else. You can buy coverage up to $5,000 on standard shipments, or up to $50,000 through Registered Mail.15USPS.
