When it comes to sending parcels, size definitely matters. Not in a braggy way - we’re talking practicality here. Choosing the right size for your parcel ensures a smooth drop-off, a happy locker, and a delivery that’s right on track. That’s why we’re here with a friendly nudge to help you avoid the old “locker full” surprise. Spoiler: it's super easy to check locker space before you go! 

Check before you chuck (your parcel in the locker) 

We get it - you’ve packed your parcel perfectly, downloaded the label, and are on your way to drop it off. But before you dash out the door, take a sec to check locker availability on our website or in the InPost app. It takes just a moment and can save you a wasted trip. 

Just tap in your location and we’ll show you the nearest lockers, plus how full they are. No more guessing games or driving around on a locker treasure hunt. Win-win.
