track 24 mail

[sunflower9876]

We put a Tracked 24 large letter in a postbox yesterday not realising it shouldn't be posted in this way. Can anyone tell me what will happen to it. It is not appearing on the tracking system.
Thanks

It won't appear on the tracking system and will likely just go through like normal post. It needs scanning at the post office to go into the tracking system

I did exactly the same recently and it only appeared on tracking once it had been signed for at the other end, so I couldn't see it's journey but did still get the assurance that it had been received which is the important part anyway.

Thanks @dementedpixie and @icklepiglet. Advice/experiences very helpful 😀
