How to serialize with more than 20 bytes

Hi.
Is there any way or idea to serialize certain event using user_id which is hashed and has more than 20 bytes?
thanks

Based on documentation: https://experienceleague.adobe.com/docs/analytics/implementation/vars/page-vars/events/event-seriali...

"Valid values are alpha-numeric characters up to 20 bytes in length. If you enter a value that is longer than 20 bytes, then the system truncates it to the first 20 bytes."

AEP size might differ but if you create an Analytics services integration in the datastream I would guess the same size limit will be applicable

Yes, I wish that Adobe would update serialization to take more than 20 characters, particularly since system GUIDs are so popular, and those are generally 36 characters, but could be longer...

I've posted an idea about this, https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-ideas/serialization-length-is-overd...

Please add your comments, and any additional details you would like to see, and give it a like to upvote it.

We can't strip the characters.

Anyway thanks for your post.
I liked it.
I do hope this could lead to some improvement.

Oh I agree, stripping characters only works for me on the Google Play transaction IDs... and even then I am stripping from the Order ID field that is used for serialization, then I store a non-stripped version in a custom eVar....

But for Serializing account registrations, our GUIDs are 36 characters, even stripping the dashes out, only gains me a few extra unique values, but not what I truly need to properly serialize my custom event....

Yes! so that's the problem.
I don't know how people can handle this problem.
