v7.9.0: ID Generator

Compare Source

New: ID() — Fast, Human-Readable Random Identifier

(GoFakeIt v7.9.0)

gofakeit.ID() is a new high-performance identifier generator designed for speed, readability, and practically zero collision probability.

Unlike UUID v4 or XID, this generator is intentionally random-first, not structure-based.
Perfect for mock APIs, test data, fixtures, seed data, and temporary identifiers.

---

Highlights

• Human readable alphabet, no confusing characters
  → 23456789abcdefghjkmnpqrstuvwxyz (no 1, l, i or 0, o to alleviate confusion)
• Fast
• Memory Allocation
• Generates from your rand source
• Shorter than UUID, faster than XID, and requires no coordination

---

Example

id := gofakeit.ID()
fmt.Println(id)
// → "3t9qf4c92npxhw7bg6y0"

---

Performance Benchmarks

Measured on Go 1.25

Generator / Function	Benchmark Name	ops/sec	ns/op	B/op	allocs/op
gofakeit.ID()	BenchmarkID-10	31,383,146	37.8 ns	24	1
gofakeit.UUIDv4()	BenchmarkUUIDv4-10	22,131,577	53.8 ns	48	1
github.com/rs/xid	BenchmarkXID-10	16,190,817	74.2 ns	0	0
github.com/google/uuid (v4)	BenchmarkGoogleUUIDv4-10	3,098,770	386.1 ns	64	2

Takeaway: gofakeit.ID() is ~2× faster than XID and ~10× faster than UUID v4, while being shorter and human-readable.

Collision Probability (Randomness Math)

• ID length: 20 characters
• Alphabet: 32 slots with one duplicated character (intentional) → avoids retries, maximizes speed
• Effective entropy: ≈ 98.25 bits

Even under very large bursts, duplication is astronomically unlikely

Collision probability when generating n IDs within 1 second (birthday bound)

n (IDs in 1s)	gofakeit.ID() collision probability
100,000	0.00000000000000000001326
1,000,000	0.000000000000000001326017
10,000,000	0.000000000000000132601736
100,000,000	0.000000000000013260173678
1,000,000,000	0.000000000001326017367838

For comparison (same n):

• UUID v4 (122 bits): much lower probabilities (but significantly slower and longer)
• XID: structural uniqueness (time + machine + pid + counter). Treat collisions as operationally zero when configured normally.

Need structural, sortable IDs? Use XID or Snowflake.
Want random, readable, fast? Use gofakeit.ID().

RNG Behavior

Mode	Behavior
Default (gofakeit.ID())	PCG for speed, seeded via crypto/rand → fast + unpredictable
Full crypto (NewFaker(source.NewCrypto()))	crypto/rand for every ID → maximum randomness (slower)
Deterministic (New(seed))	PCG with fixed seed → reproducible ID sequences (useful for tests/fixtures)

We seed PCG with a cryptographic seed when seed == 0. This prevents accidental identical streams across processes/containers.

---

Example Usage

package main

import (
	"fmt"

	"github.com/brianvoe/gofakeit/v7"
	"github.com/brianvoe/gofakeit/v7/source"
)

func main() {
	// Fast ID — PCG, automatically crypto-seeded
	fmt.Println("fast ID:", gofakeit.ID())

	// Cryptographically secure per-ID RNG
	crypto := source.NewCrypto()
	faker := gofakeit.NewFaker(crypto, true)
	fmt.Println("crypto ID:", faker.ID())
}

📚 New Feature: ISBN Generation

This release adds support for generating valid ISBN identifiers, perfect for mock book data or publishing applications.

Generate a valid ISBN-10 or ISBN-13 string with customizable separator.

gofakeit.ISBN(ISBNOptions{Version: "13", Separator: "-"}) // "978-1-2345-6789-0"

🧰 Options

Field	Description
Version	"10" or "13" (default is "13")
Separator	Custom string separator (e.g. "-", "")

Thanks to @​phoenisx , gofakeit is even more versatile for testing systems that work with books, publishing tools, or educational content.
