Protect every shipment with shipping address verification
ShipStation verifies and standardizes addresses before labels are created, so packages reach customers on time and at the right door. Catch errors early and reduce delivery mistakes for a smoother shipping process.
Driving fulfillment for the world’s leading brands
Make every address accurate before you ship
ShipStation checks each address as you enter it to catch errors instantly. This helps prevent failed deliveries, avoids costly reships, and keeps customers satisfied without slowing down your team or complicating workflows.
Reduce failed deliveries and unexpected costs
Invalid or incomplete addresses can cause delayed shipments, returned packages, and surprise carrier fees. ShipStation verifies every supported address against trusted postal databases before you buy a label to catch any errors as early as possible. This means fewer reships, more accurate deliveries, and lower overall shipping costs.
Speed up fulfillment with easier manual edits
Automatically flag missing apartment numbers or misspelled streets so your team doesn’t have to constantly hunt for errors. Simple icons indicate which addresses are ready to ship and which need review. Your team can quickly scan, fix, and keep orders moving to save time and confidently ship at scale.
Deliver a smooth customer experience
Accurate addresses lead to more reliable deliveries and fewer “where is my order?” inquiries. ShipStation verifies each address and standardizes details like street abbreviations and ZIP codes, so shipments move quickly and correctly. Every on-time arrival helps build brand trust and keeps customers happy.
Address validation that keeps shipments moving
Check address status at a glance
Prevent shipping delays and costly mistakes by spotting address issues before labels are printed. ShipStation clearly shows which orders are ready to ship and which need attention, so your team can move faster with confidence. Quickly identify residential, commercial, and international addresses to keep fulfillment accurate, efficient, and on track.
Automatically correct errors
Print correct addresses for domestic and international shipments. ShipStation cleans up abbreviations, formats postal codes, and can even add plus-four extensions to U.S. ZIP codes. You decide when to apply automatic corrections and when to keep addresses as entered, giving you the right balance between automation and control.
Set the right rules for every store
Customize address validation for each store so it works the way you do. Automatically correct addresses where data is unreliable, and leave trusted systems untouched—all while validating every order. You stay in control across channels, with fewer surprises and smoother shipping from every store.
See roadblocks ahead of time
ShipStation flags missing or incorrectly formatted address details with clear warnings or errors. Warnings highlight issues like extra or unverified information, while errors indicate problems with fields such as City, State, or Postal Code. In many cases, you can still attempt label creation. If the carrier rejects the address, you get the information you need to correct it and try again.
API tools for developers
ShipStation’s API makes address validation simple to build into your shipping flow. Validate, clean, or skip checks during label creation with a single request. Addresses are verified against trusted databases, updated when better matches are found, or returned with clear error codes—so you can ensure clean data and reliable shipping in real time.

How are international addresses verified in ShipStation?
ShipStation uses trusted postal databases for each supported country in the platform. The process is similar for domestic and international addresses, but may require checks for formatting, postal codes, and local address rules.
Can I verify an address without losing control of my data?

How can developers use API services to check addresses?
Developers can use ShipStation’s label API to verify addresses in real time. By setting the validate address property on label requests, they can check address details, correct them automatically, or surface validation errors inside their own tools. This makes it simple to add shipping address verification to custom workflows and platforms.
