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.

Gofakeit v7: What's New!

🎲 math/rand/v2 Integration

• Better RNG 🔒: Now using math/rand/v2 for a more simplistic implementation and two new source types(pcg, chacha8).
• Simplified faker 🧹: Refined faker struct for ease of use, mirroring the simplicity improvements of math/rand/v2.

✨ Highlights

• New Sources : math/rand/v2 added PCG and ChaCha8. Gofakeit also added a sub package called source with additional sources in it.

Example New and NewFaker usage

import (
	"github.com/brianvoe/gofakeit/v7"
	"github.com/brianvoe/gofakeit/v7/source"
	"math/rand/v2"
)

// Uses math/rand/v2(PCG Pseudo) with mutex locking
faker := gofakeit.New(0)

// NewFaker takes in a source and whether or not it should be thread safe
faker := gofakeit.NewFaker(source rand.Source, threadSafe bool)

// PCG Pseudo
faker := gofakeit.NewFaker(rand.NewPCG(11, 11), true)

// ChaCha8
faker := gofakeit.NewFaker(rand.NewChaCha8([32]byte{0, 1, 2, 3, 4, 5}), true)

// Additional from Gofakeit sub package source

// JSF(Jenkins Small Fast)
faker := gofakeit.NewFaker(source.NewJSF(11), true)

// SFC(Simple Fast Counter)
faker := gofakeit.NewFaker(source.NewSFC(11), true)

// Crypto - Uses crypto/rand
faker := gofakeit.NewFaker(source.NewCrypto(), true)

// Dumb - simple incrementing number
faker := gofakeit.NewFaker(source.NewDumb(11), true)
