The answer lies in the Human-Computer Interface (HCI). Humans are notoriously bad at reading long, unbroken strings. The chances of misreading 7d2a2a4cd13dcf29e7f7 are high. By grouping the characters——developers utilize a technique called "chunking." This cognitive psychology principle allows humans to process small groups of information more effectively. It reduces the error rate when a user must manually type the key into an activation field or read it over the phone to a support technician.
The security and utility of an identifier like rely heavily on entropy. If identifiers were sequential (0001, 0002, 0003), systems would be vulnerable to prediction attacks. A malicious actor could guess the next record to be created and intercept data.

For developers: If you control a system that outputs codes in 7d2a-2a4c-d13d-cf29-e7f7 format, consider adding a prefix like KEY- or ERR- to improve human readability and reduce confusion.
