UUID V4
128 bits, 16 bytes
122 bits of entropy, 5.31691198 × 1036 possible IDs
“...the odds of collision between any two is 1 in 2.71 x 1018 Put another way, one would need to generate 1 billion v4 UUIDs per second for 85 years to have a 50% chance of a single collision.”

OLC IDs
7 bytes
51.863 bits of entropy, 4.096 × 1015 possible IDs
Open Location Code (OLC) alphabet Ids. OLC is a geocoding system that encodes latitude and longitude into a short string of characters. The alphabet is simplified to use only uppercase letters and digits, excluding characters that can be easily confused (like '0' and 'O', '1' and 'I').
