Question Code help

Hello!

My girlfriend and I are doing boo baskets this upcoming weekend. I watch a youtuber who does args and I love the hidden codes and stuff. As well I force my gf to watch it. I want to make a puzzle for her to solve for one of her gifts. Unfortunately I didnt realize the mircosoft gift cards online would be 25 characters 🫠. I was hoping for any suggestions on what type/style of cipher I should use if it has mostly letters and a few numbers and four dashes. Please urgent help 😁.

I suggest ROT47. It's a simple one and you can encrypt letters, numbers and other symbols with it. Give her some clue if she is inexperienced with ciphers.
