How does ShippingEasy validate addresses?

As part of processing each order, ShippingEasy validates domestic addresses through a US address validation tool from USPS. International addresses are validated through the Melissa Data Global Address Check Tool.

Common Domestic Address Errors

ShippingEasy tries to avoid marking domestic addresses as invalid for minor spelling and punctuation errors. As long as the address is "deliverable" as defined by the latest USPS Delivery Point Validation data, ShippingEasy will not mark the address as invalid.

Instead, ShippingEasy can automatically correct minor spelling and punctuation errors. Learn how to enable auto-correction of minor spelling and punctuation errors in addresses.

These example addresses are eligible for auto-correction by ShippingEasy:

Automatic ZIP Code Correction

For domestic addresses, ShippingEasy will automatically replace invalid ZIP code values whenever the address provides enough information to calculate the correct ZIP code. In addition, ShippingEasy will add the appropriate ZIP+4 code.

Address Errors That Cannot Be Corrected

If a domestic address is not in the USPS Delivery Point Validation database, it is considered invalid by ShippingEasy.

A domestic address is usually marked as invalid for one of two reasons:

Incorrect street number or name: For example, 23616 Summer Pine Dr, Spring, TX 77373 has a street number that does not exist. Tax records for that part of Texas list 23614, 23618, and 23622 as valid street numbers for Summer Pine Dr, but not 23616.
The address exists but does not receive mail service: The USPS defines an eleven-digit delivery point code for every domestic address. If the USPS has not assigned a delivery point code, then the address is invalid. Example: 940 Constitution Blvd, New Kensington, PA 15068 is an accurate street address but gets no postal service.
