Laravel-USPS

Full Laravel package for the USPS API v3 (OAuth2). Covers all 20 USPS API domains: addresses, tracking, labels, international labels, domestic prices, international prices, service standards, locations, carrier pickup, containers, payments, campaigns, package campaigns, adjustments, disputes, appointments, shipping options, and SCAN forms.

Note: The legacy USPS Web Tools XML API was retired in January 2026. This package uses the new OAuth2-based REST/JSON API at apis.usps.com.

Reference: Official USPS API examples and OpenAPI specs at github.com/USPS/api-examples.

Requirements

• PHP 8.1+
• Laravel 10, 11, 12, or 13
• USPS API credentials from developer.usps.com

Installation

composer require johnpaulmedina/laravel-usps

The service provider and facade are auto-discovered.

Configuration

Publish the config file:

php artisan vendor:publish --tag=usps-config

This creates config/usps.php:

return [
    'client_id' => env('USPS_CLIENT_ID', ''),
    'client_secret' => env('USPS_CLIENT_SECRET', ''),
];

Add your credentials to .env:

USPS_CLIENT_ID=your-client-id
USPS_CLIENT_SECRET=your-client-secret

Artisan Commands

# Validate an address
php artisan usps:validate "1600 Pennsylvania Ave NW" --state=DC --zip=20500

# Track packages
php artisan usps:track 9400111899223456789012

# ZIP code lookup (city/state)
php artisan usps:zip 33101

# Calculate shipping rates
php artisan usps:price 20500 33101 16 --mail-class=PRIORITY_MAIL

# Delivery estimates
php artisan usps:standards 20500 33101

# Find USPS locations
php artisan usps:locations 33101 --type=post-office --radius=5

All commands output formatted tables to the console.

Usage

All API domains are accessible via the Usps facade. Address methods are called directly; all other domains are accessed through fluent accessor methods that return typed API clients.

Addresses

use Usps;

// Validate an address
$result = Usps::validate([
    'Address' => '1600 Pennsylvania Ave NW',
    'City' => 'Washington',
    'State' => 'DC',
    'Zip' => '20500',
]);

Response:

{
    "address": {
        "Address2": "1600 PENNSYLVANIA AVE NW",
        "Address1": "",
        "City": "WASHINGTON",
        "State": "DC",
        "Zip5": "20500",
        "Zip4": "0005"
    },
    "additionalInfo": {
        "deliveryPoint": "00",
        "carrierRoute": "C000",
        "DPVConfirmation": "Y",
        "DPVCMRA": "N",
        "business": "Y",
        "centralDeliveryPoint": "",
        "vacant": "N"
    }
}

DPV (Delivery Point Validation) confirms whether a specific address is a real USPS deliverable location — down to the apartment/suite level.

Code	Meaning
Y	Full match — both street and unit confirmed
D	Primary address confirmed, apartment/suite missing
S	Primary confirmed, apartment/suite provided but doesn't match
N	Not a valid delivery point

When apartment is missing (e.g., multi-unit building):

{
    "address": {
        "Address2": "100 S BISCAYNE BLVD",
        "Address1": "",
        "City": "MIAMI",
        "State": "FL",
        "Zip5": "33131",
        "Zip4": "2011"
    },
    "corrections": [
        {
            "code": "32",
            "text": "Default address: The address you entered was found but more information is needed (such as an apartment, suite, or box number) to match to a specific address."
        }
    ],
    "additionalInfo": {
        "deliveryPoint": "99",
        "carrierRoute": "C038",
        "DPVConfirmation": "D",
        "DPVCMRA": "N",
        "business": "N",
        "centralDeliveryPoint": "",
        "vacant": "N"
    }
}

Correction codes: 32 = apartment/suite needed, 22 = multiple addresses found.

// Full address lookup (raw v3 response)
$result = Usps::addressLookup([
    'streetAddress' => '1600 Pennsylvania Ave NW',
    'city' => 'Washington',
    'state' => 'DC',
]);

Response:

{
    "firm": "",

        "urbanization": ""
    },
    "additionalInfo": { ... },
    "corrections": [],
    "matches": [{ "code": "31", "text": "Single Response - exact match" }]
}

// City/State lookup by ZIP
$result = Usps::cityStateLookup('20500');

Response:

{
    "city": "WASHINGTON",
    "state": "DC",
    "ZIPCode": "20500"
}

// ZIP Code lookup by address
$result = Usps::zipCodeLookup([
    'streetAddress' => '1600 Pennsylvania Ave NW',
    'city' => 'Washington',
    'state' => 'DC',
]);

Response:

{
    "firm": "",
    "address": {
        "streetAddress": "1600 PENNSYLVANIA AVE NW",
        "city": "WASHINGTON",
        "state": "DC",
        "ZIPCode": "20500",
        "ZIPPlus4": "0005"
    }
}

Note: State names are auto-converted to abbreviations (Florida → FL). ZIP codes with dashes are auto-split (20500-0005 → ZIP5: 20500, ZIP4: 0005).

API Domains

Authentication

The package automatically handles OAuth2 client credentials flow. Access tokens are cached per-scope for ~50 minutes to minimize token requests. Each API domain requests only the scopes it needs.
