Connected to the platforms that power your business
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 standardises details like street abbreviations and postcodes, 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 fulfilment accurate, efficient, and on track.
Automatically correct errors
Print correct addresses for domestic and international shipments. ShipStation cleans up abbreviations and formats postcodes. 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
Customise 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.

Shipping address verification FAQs
What is shipping address verification, and why is it important?
Shipping address verification is the process of checking an address against official databases before you ship. It helps prevent delivery failures, reduces carrier adjustments, and ensures packages reach the right destination the first time.
Which countries does ShipStation validate addresses for?
ShipStation validates addresses for a growing list of countries, including: Addresses for other destinations still flow through your shipping process, but may not receive automated validation.
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?
Yes. ShipStation always shows the original address and makes it easy to review suggested changes. You can enable or disable automatic corrections per store, edit addresses manually, and use warnings or errors as prompts to double-check addresses before you ship.
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.
Will address verification delay my shipping workflow?
No. Verification happens in real time as you enter or import orders. Warnings and errors are flagged instantly, so your team can review or correct addresses without slowing down fulfillment.
