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

12 characters, 12 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').

UUID V7

Unix ms timestamp (48-bit), random bits (74-bit total). Sortable by time.

Excellent DB performance (sequential inserts); sortable; no MAC leakage. Database primary keys; distributed systems. Recommended for most modern apps/DBs.
