Address

Address objects are used to represent people, places, and organizations in a number of contexts. For example, a Shipment requires a to_address and from_address to accurately calculate rates and generate postage.

Additionally, EasyPost offers several verification tools that can be used to detect deliverability issues, correct minor errors in spelling/formatting, and determine if an address is residential or not (which has a significant effect on Shipment rating for many carriers).

Address Verification by Country

The address verification service supports over 240 countries and territories. Verification levels vary by country. Coverage is continuously expanding to support more global addresses.

Create an Address

Depending on your use case an Address can be used in many different ways. Certain carriers allow rating between two zip codes, but full addresses are required to purchase postage. It is recommended to provide as much information as possible during creation and to reuse these objects whenever possible.

Address objects can also be created inline while creating another object, for example during Shipment creation.

An Address object is immutable once created. All information must be provided during creation; it cannot be modified later.

i.e. 417 Montgomery St

Verify an Address

Verifying an Address before shipping is a great way to reduce issues with delivery.

An address can be verified by including one of the following parameters during creation:

  • verify: Performs standard delivery and ZIP+4 checks.
  • verify_strict: Performs strict verification. If any check fails, the request will return an error.
  • verify_carrier: Allows carrier-grade verification with UPS or FedEx. Must be set to "ups" or "fedex" and used in combination with verify or verify_strict (true).

The most effective time to perform address verification is when the delivery address is entered. If verification fails, request confirmation from the person entering the data, as they may know their address more accurately than the verification process.

The examples below demonstrate different verification options, including delivery checks and strict verification.

Note: As of August 25, 2025, EasyPost only abbreviates street names for USPS address verification when the validated street1 field exceeds 40 characters.
