UUIDs are pretty big when serialized to text; this makes use cases like QR codes and SMS unwieldy in my experience. YMMV

  You can also chose to encode them there in a less spacy format and have best of both worlds.

  Usually you want to store them as integers when possible, like in DB or QR. For text formats like SMS I've often seen base-64 or similar with more characters.
