UUID V4

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
16 characters, 16 bytes (15 random characters + 1 check character)
64.829 bits of entropy (15 random characters), 3.2768 × 1019 possible IDs
Enough for about 3.8 billion unique IDs for every living person (~8.3 billion) and company (~377 million) on Earth. The average American opens between 60 and 90 unique financial accounts. For financially active individuals or those optimizing rewards and interest yields, this figure routinely exceeds 100 accounts.
About OLC IDs and the checksum
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').
The 16th character is a checksum: a Luhn mod 20 check character computed from the first 15. Each character is mapped to its position in the alphabet 23456789CFGHJMPQRVWX (2 = 0 through X = 19). Moving right to left, every other value is doubled, starting with the rightmost; a doubled value of 20 or more has 19 subtracted (the sum of its base-20 digits). The values are added up, and the check character is the one at position (20 − (sum mod 20)) mod 20. It catches any single mistyped character and most swaps of two adjacent characters. Hyphens are ignored.

Encrypted URL IDs (GUID)
Base64URL encoded encrypted V7 UUID tokens. Each token packs an 8-byte random IV plus a UUIDv7 XOR-masked with an HMAC-SHA256 keystream derived from the IV and a private key, so the token is opaque and non-sequential in URLs but still reversible to recover the original UUIDv7 (and its embedded timestamp) server-side.
