I have multiple Amex cards ending in 1000. I've not found a way on apps like Uber and Lyft to know which card I'm selecting as they don't give any other info such as expiration date and full card #. Today, I made the decision to forego Uber even though it was cheaper, because I need to charge to a specific card and it won't let me add it; I already had a card ending in the same 1000, not sure if that's the cause. I ended up using Lyft, but it also has multiple cards ending in 1000, it was impossible to tell them apart and I had to delete both and add the right one back.

Very frustrating. Comes up again and again.
